‘My laundromat accepts Apple Pay. Why won’t they take my cash?’

Mary Anna Mancuso at the Miami Herald

Cash “isn’t going out of circulation; it’s disappearing from everyday transactions,” says Mary Anna Mancuso. Businesses “prefer electronic payments” because it “reduces the risk of robbery, digital transactions go into the bank almost immediately and the bookkeeping is simpler.” But it is “worth asking what we lose when convenience becomes the only option.” A “modern payment system should accommodate everyone — whether they choose to tap their phone, swipe a card or hand over a dollar bill.”

‘Ukraine has always been here — and always will be’

Lidia Pilecky at the Chicago Tribune

Ukraine’s “history tells the facts. We were here. We are here. And we will remain here,” says Lidia Pilecky. For “centuries, Russian rulers repeatedly tried to ban the Ukrainian language and suppress the very identity Putin claims never existed.” But “today, Ukrainians defend the universal principle that no nation should be destroyed because a more powerful neighbor claims it has no right to exist.” Ukraine’s “fight is also taking place in classrooms where children learn the truth.”

‘Cyclospora outbreaks will only get worse as climate chaos grows’

Amy Moas at Newsweek

This “has been one of the most dangerous summers on record, and experts have been warning about it for decades,” says Amy Moas regarding “two deaths linked to the outbreak of cyclospora.” It is “easier to associate loss of life with extreme weather when it’s tied to a singular event.” But “you can ‘contact-trace’ this now-fatal outbreak back to the ongoing climate crisis.” If “summer gets longer and warmer, we’ll see a longer, hotter mechanism for the parasite to thrive.”

‘Fancy sodas fall flat with me’

Brenda Cronin at The Wall Street Journal

Fancy sodas “come in winsome bottles or sleek cans and have ridiculous flavors like watermelon-dandelion or rosehip-jacaranda,” but “they taste like carbonated cough syrup with a Windex chaser,” says Brenda Cronin. People “should be reveling in the gourmet soda parade,” if “only the flavors didn’t sound like products from Bath & Body Works” or “taste like a mashup of SweeTARTS and Jolly Ranchers.” When “drinking feels more like penance than a party, I’ll do without.”

What happened

Scientists at Stanford University on Thursday reported in the journal Science that they had successfully directed artificial intelligence to create 16 new viruses. This first-ever use of AI to design and build viruses not found in nature raised “hopes for medical advances” like eliminating drug-resistant bacteria, The New York Times said, while also “raising the disturbing possibility that the technology could someday be used to invent dangerous pathogens.”

Who said what

“Synthesizing viruses from scratch is hardly new,” the Times said, but the Stanford and Arc Institute researchers went “well beyond” previous efforts by teaching AI to “recognize patterns of DNA structure in nature, and then to use that data to write recipes for entirely new viruses.” Their AI tool, Evo, was fed genetic sequences “much like ChatGPT and other language models are trained on large sets of existing text material,” CNN said.

What next?

The new study “arrives at a moment of heightened anxiety regarding danger posed by increasingly powerful AI models,” The Wall Street Journal said. Evo was constrained to create “simple viruses” that can “only infect bacteria and pose no threat to humans.” But the breakthrough “raises urgent biosafety and biosecurity questions,” Johns Hopkins health security experts said in a corresponding Science article. “The ability to compose viral genomes using generative AI now exists; the governance to safely steer it does not.”

What happened

The Senate Homeland Security Committee on Thursday voted along party lines to hold former U.S. infectious disease chief Dr. Anthony Fauci in contempt of Congress for repeatedly refusing to answer questions during testimony on the federal response to Covid-19. Committee Chair Sen. Rand Paul (R-Ky.) and other Republicans contended that Fauci could not invoke his Fifth Amendment rights “because he’d already received a preemptive pardon from former President Joe Biden,” CNN said. But “GOP lawmakers also openly acknowledged” last week that they “hoped to get Fauci to perjure himself in his testimony, allowing them to bring new charges.”

Who said what

“Fauci faced no risk of federal prosecution,” Paul said. “All he had to do was tell the truth.” Fauci’s lawyer called the vote a “crude political stunt” to “punish” a public servant for “exercising his constitutional rights.” Paul appears so “hellbent on putting Fauci in jail” that his office immediately hand-delivered the contempt resolution to federal prosecutors, Politico said. Contempt referrals “rarely bypass the full Senate,” The Wall Street Journal said, and “it isn’t clear whether a referral made in such a manner is legally valid.”

What next?

The Justice Department on Thursday evening said it had received Paul’s referral, is “reviewing it and will work with the Senate accordingly.” If prosecutors decide to file charges and win a conviction, Fauci faces up to a year in prison.

‘The godmother of the “conspiracy mom”’

Jessica Winter at The New Yorker

After JFK’s assassination, Oklahoma housewife Shirley Martin “flung herself into investigating the crime and getting to know some of those closest to it,” says Jessica Winter. It is “generally understood today, as it was not understood 60-plus years ago, that those who subscribe to conspiracy theories tend to do so in order to make sense of an unstable reality,” and “in some ways, Martin was a preview of today’s post-Covid, stay-at-home ‘conspiracy mom’ or of the MAHA moms.”

In China, a “risky experimental treatment was undertaken for a nonfatal condition; oversight by external authorities, regulators and ethical review boards in China was insufficient to avert tragedy,” says Anjana Ahuja. The “episode is another blow to a country vying to become a global leader in biotech,” as “truly advancing science means being open, honest and transparent about mistakes, as well as successes.” Parents “crave better lives for their children and ambitious researchers covet world firsts.”

It “may seem absurd to say that deadlifts and squats and bench presses changed my life,” but “then again, it wasn’t long ago that I couldn’t lift a coffee cup without excruciating pain,” says Emily Hoeven. It is “almost impossible to name an area of life that weightlifting doesn’t improve.” Studies “show that it boosts confidence and mood, strengthens bones, reduces joint pain and chronic inflammation, and improves cognition,” and it “can be especially beneficial for older women.”

‘How to fight a cloud’

Nitish Pahwa at Slate

It “feels like an inflection point” for the construction of AI data centers, as “more community leaders and elected officials are listening to their concerned constituents and hitting the pause button,” says Nitish Pahwa. But an “even bigger fight is at hand: whether these halts on buildouts will eventually lead to permanent bans, or whether elected officials are just kicking the clankers down the road.” It’s “one thing to impose a pause for a period of time” but “another to actually make use of that time.”

What happened

The Senate on Wednesday confirmed Dr. Erica Schwartz as the Centers for Disease Control and Prevention’s first permanent director in nearly a year. Schwartz is “widely considered a qualified and traditional selection for the role,” Politico said. She “has repeatedly affirmed the safety and efficacy of childhood vaccines,” The New York Times said, but the 51-44 vote “fell mostly along partisan lines.”

Who said what

Schwartz will take over a “public health agency beleaguered by political meddling and low morale,” The Associated Press said. Her predecessor, Susan Monarez, was ousted after less than a month following a clash with Health Secretary Robert F. Kennedy Jr. over vaccine policy, The Wall Street Journal said, and the White House was “looking for a CDC nominee who would minimize controversy” this time around.

What next?

Sen. Tim Kaine (D-Va.) said he joined Republicans in voting for Schwartz because public health leadership is urgently needed amid the U.S. outbreaks of measles and cyclosporiasis and Congo’s Ebola crisis. “It’s becoming very obvious what happens when the invisible workings of public health are not functioning the way we need them to,” Johns Hopkins biosecurity expert Gigi Gronvall told The New York Times. But it’s not clear “how much good” Schwartz can do when “the main problem is RFK Jr.”

TV might actually be rotting our brains. Watching television for extended periods of time could increase the risk of dementia and Alzheimer’s disease, new research says. To combat this danger, experts recommend taking breaks from binge-watching and engaging in more mentally stimulating activities.

Your brain on TV

Frequent TV watching in midlife was associated with reduced volume in the parts of the brain vulnerable to Alzheimer’s disease, according to a study published in Alzheimer’s & Dementia. The diminished brain systems include those associated with memory and cognition as well as executive functioning. More surprisingly, the brain volume reduction was not tied to sedentary behavior but specifically to watching TV. “People whose jobs involved sitting for much of the day tended to have healthier-looking brains,” said ScienceAlert. Also, “when the researchers accounted for differences in overall physical activity, that didn't seem to impact the outcome.”

The results also showed that men were particularly vulnerable to these brain changes. “This could be because men and women accumulate sedentary time differently,” Natan Feter, a biological scientist and the lead author of the study, said to ScienceAlert. “Women may interrupt their sitting more often,” or “biological differences in how the brain responds to prolonged sedentary behavior” may be to blame. In general, “women tend to prefer TV programming in shorter chunks, though they spend more time watching overall,” said ScienceAlert. By contrast, “men’s preferences for watching sports and movies” mean they are are “more likely to spend long, uninterrupted periods on the couch.”

Researchers analyzed a sample of 1,712 adults with an average age of 53 years who did not have a diagnosis of dementia when the research began. Between 1987 and 1989, “participants completed a detailed physical activity questionnaire during an in-person interview” where they reported “how often they watched television during their leisure time,” as well as “answered specific questions about how often they sat down during their work hours,” said PsyPost. Between 2011 and 2013, the participants underwent an MRI of their brains.

The study “shows an association, not a cause-and-effect relationship” between TV and dementia, Feter said to Healthline. The researchers also “relied on self-reported data for TV consumption, which can be less precise than timed tracking,” said a news release about the study.

Beyond the screen

“For years, we’ve focused on how much people sit,” David Raichlen, a professor of biological sciences and anthropology at the USC Dornsife College of Letters, Arts and Sciences and the senior author of the study, said in the news release. But these findings “suggest we should also pay attention to what they’re doing while they’re sitting.” For example, working from home, while sedentary, is more “intellectually stimulating” compared to watching TV, said the release.

Because TV watching appears to specifically affect the brain, “we might eventually see a different approach to health guidance around sedentary activities,” said the release. “Rather than just directing their patients to move more, for example, physicians might recommend they reduce television time and add cognitively engaging activities for when they do sit.” Activities like “puzzling, crafts and even texting, which require your brain to work while you are sitting might also change how much sitting negatively impacts your brain,” said ScienceAlert.

“The goal is not to eliminate passive rest,” Dung Trinh, a doctor at the MemorialCare Medical Group and the chief medical officer of Healthy Brain Clinic in Irvine, California, said to Healthline. It is to “build more cognitively engaging moments into the day.”

‘One problem with attacking the Smithsonian? Americans like it.’

Kelsey Ables at The Atlantic

Even as the “museum complex continues to face a pressure campaign from the White House, public fondness for the Smithsonian — for its free entry and eclectic collections — is hard to break,” says Kelsey Ables. Museums have “been largely immune to the most deleterious effects of the culture wars.” Most “Americans, unlike the president, seem to trust these entities to do their thing” so “coming after a history museum may not be the base-galvanizing issue the White House hopes it is.”

‘The US government’s mislabeled map of Africa at a global AIDS conference shows again a failure to understand the continent’

Kenneth Ngure at The Guardian

At the 26th International AIDS Conference, a “slide presented by a senior U.S. State Department official displayed a map of Africa with country names glaringly scrambled and mislabeled,” says Kenneth Ngure. While the “mistake apparently occurred due to an overreliance on AI tools, it carried a painful symbolic weight.” The map “reinforced a longstanding frustration: that too many political leaders treat Africa as a monolithic abstraction rather than a continent of 54 distinct sovereign nations.”

‘Why patients wait months for care they don’t get’

Tessa Adzemović at The Boston Globe

Hospitals “were never designed to become long-term accommodations, but that’s become a reality for a select population,” says Tessa Adzemović. These “patients are medically cleared to leave but cannot be discharged because of capacity bottlenecks, insurance delays or legal complexities.” Many “prolonged hospitalizations have significant implications for patient outcomes, hospital resource utilization and healthcare costs.” The “reasons for these delayed discharges range from financial to administrative to legal, so any solution to the problem must be multifaceted.”

‘“Ted Lasso” is back, but is his moment over?’

A.A. Dowd at The American Prospect

As “comebacks go,” a new season of “Ted Lasso” is “not exactly improbable,” says A.A. Dowd. The show “remains one of the most widely watched series of the last decade, a true juggernaut of popularity.” But at “what point does a show go from having its finger planted firmly on the pulse of now to suddenly looking more out of touch than anything else?” We “may have reached the moment when Ted Lasso’s brand of turn-the-other-cheek humanism is no longer enough.”

What happened

Ariana Grande “will be taking a step back from visibility” following the conclusion of her world tour due to “endless, ongoing public scrutiny,” a representative for the Grammy winner told People over the weekend. The announcement follows the Friday release of Grande’s “Petal” music video, which “reignited fan concerns about her weight loss,” Variety said.

Who said what

“She looks emaciated” in the video, with “sunken” cheeks and a “protruding” ribcage, said critic Monica Hesse in The Washington Post. Grande’s team is “thoroughly irresponsible for not guiding her away from this deeply damaging image for her young fans to see so glamorized,” actor and activist Jameela Jamil said in a now-deleted Instagram post.

The hiatus decision “was made from a thoughtful and empowered place,” Grande told fans during a tour performance in Chicago. “Human beings can need a break sometimes.” She “performs a very physical show,” a source close to the star told People, “and there is a lot of athleticism involved.”

What next?

Grande will finish her Eternal Sunshine tour on Sept. 1 and then take a “much-deserved break,” her representatives said. Her team confirmed that she is also pulling out of leading a revival of Stephen Sondheim’s “Sunday in the Park With George,” which was expected to open next summer in London’s West End.

What happened

Michigan health officials on Monday confirmed the first two deaths linked to the ongoing cyclosporiasis outbreak. The fatalities mark the “first known deaths related to the multi-state outbreak of explosive diarrhea in the United States,” CNN said.

Who said what

Both victims had “significant underlying health conditions” that may have been “impacted by cyclosporiasis and dehydration,” Michigan’s Department of Health and Human Services said in a website update. The parasitic infection is “generally not a life-threatening illness.” This is the “worst year on record for cyclosporiasis” in the U.S., said The New York Times, and Michigan is “at the center” of the “nine-state outbreak linked to iceberg lettuce supplied by Taylor Farms.”

What next?

Health experts in Michigan are “cautiously optimistic” that the outbreak there is “starting to wane,” said the Times. But the deaths reinforce the “importance of continuing efforts to investigate the outbreak, identify its source, and prevent additional illnesses,” food safety expert Wade Syers said to the Detroit Free Press.

Microplastics could be responsible for a lot of heartache. The tiny pieces of plastic have been found in high amounts in patients who suffered from heart attacks, leading experts to question their effect on cardiovascular health. Plastic likely has a more significant impact on health than we currently know and should be taken into account in analyzing environmental risk management.

Heart of plastic

Microplastics were “detected significantly more frequently” in patients who suffered heart attacks, said a study published in the European Heart Journal. Among those who had heart attacks, “micro and nanoplastics were detected in 84% of patients, compared with 40% of patients with chronic ischemic heart disease and 32% of patients with normal coronary arteries,” said a press release about the study.

The “highest levels of plastics were in blood drawn from the blocked artery itself, at the site of the blockage,” said Time. These tiny plastic particles are “found virtually everywhere in the environment, including the air we breathe, the water we drink and many foods we consume,” Pasquale Paolisso, the first author of the study, said in the release. “Scientists have begun to detect these particles in human tissues and organs, raising concerns about their potential health effects.”

The study also found that “people who smoke were six times more likely to have detectable micro and nanoplastics in the blood supplying their hearts than non-smokers,” David C. Gaze, a senior lecturer in chemical pathology at the University of Westminster, said in The Conversation. Therefore, along with the well-known detrimental effects of cigarettes, they “may also act as an efficient delivery system for microscopic plastic particles.”

The same pattern for smoking held for those who were exposed to bad air quality. “Both exposures appeared to amplify each other,” Paolisso and Emanuele Barbato, another author of the study, said to El País. “All patients who smoked and lived in areas with high air pollution had detectable plastics, compared with only one in eight of those who neither smoked nor were highly exposed.”

World of plastic

The study’s findings “do not prove that microplastics cause heart attacks, but they reveal a strong association between environmental exposures, microplastics in the blood and cardiovascular disease,” Barbato said in the press release. Microscopic plastic particles are present in “synthetic clothing fibers, tire wear, degraded packaging and countless other environmental sources,” Gaze said in The Conversation. But “at the moment, we cannot measure our exposure to plastics” in an accessible way, Rocco Montone, an interventional cardiologist at Fondazione Policlinico Universitario Agostino Gemelli in Rome, said to Time.

Microplastics were previously “found inside the liver, kidney, intestine and human brain, among other tissues,” said El País. Scientists have been interested in the health implications for some time. This study “reframes the issue of microplastics not as an isolated curiosity but as another link in a wider environmental exposome interconnected with the air we breathe and our habits,” the study authors said to El País.

The apparent connection between microplastics, smoking and air pollution also “underscores the urgent need to shift from isolated risk factor management toward comprehensive environmental health strategies,” said the study. Such strategies may include the “integration of air quality monitoring, anti-smoking interventions, plastic pollution reduction and exposomic assessment into cardiovascular disease prevention guidelines.”

“America is about to go over a peptide cliff,” said Tom Bartlett in The Atlantic. An FDA advisory panel voted last month to recommend that six unproven peptides be added to the list of custom drugs that so-called compounding pharmacies can sell. Peptides are chains of amino acids that tell cells to regulate biological processes; some peptides, including insulin and GLP-1s, are FDA-approved medicines. But pharmacies were banned in 2023 from dispensing these six peptides—which adherents claim deliver benefits ranging from improved endurance to reduced inflammation—over efficacy and safety concerns. That annoyed Heath Secretary Robert F. Kennedy Jr., a peptides fan, who added eight new members to the panel ahead of the vote, six of whom run clinics that offer the chemicals. The vote is only a recommendation, but “ultimate approval seems likely”—to the glee of sellers anticipating a “peptide gold rush” and the horror of experts who fear we’re opening a “Pandora’s box.”

Demand for injectable peptides is surging “thanks to the endorsement of podcasters, wellness influencers,” and celebrities, said Emily Mullin in Wired. Among the chemicals that got the nod from the panel are two that combine to make the Joe Rogan–backed “Wolverine stack,” which supposedly aids in injury recovery. Undaunted by the lack of evidence that they work, users currently buy peptides on the “unregulated gray market”; the chemicals are sourced from labs in China and India and sold as for “research use only.” The vote “exposed a deep divide” between Kennedy’s appointees and FDA scientists, said Yonathan Daniel in ABCNews.com. The latter cited the absence of clinical trial data and the possibility of harmful immune reactions. But proponents argued thousands of people already take potentially dangerous black market peptides, and that the agency should protect them by granting access to safer product.

This isn’t “just about peptides,” said Julia Belluz in The New York Times. It’s “part of a broader push” to increase access to drugs that haven’t met “the strict evidence standards the FDA usually requires.” The agency “wasn’t designed for this wellness-crazed” telehealth era, in which Americans are “going outside the bounds of traditional health care in growing numbers.” But the FDA is “the only thing standing between consumers and a Wild West market” for untested and potentially harmful drugs. “There has to be a better way forward” than dropping standards and allowing consumer demand to override “scientific evidence.”

‘Kids lose more than just books when school is on a screen’

Sarah Schneider Kavanagh and Katie A. Danielson at The Washington Post

Parents “don’t realize how different many aspects of elementary school have become,” say Sarah Schneider Kavanagh and Katie A. Danielson. Screens “organize the school day,” and “these technological changes in elementary classrooms might look like progress.” But “attention span in particular is weakened when schools prioritize constant stimulation over intellectual endurance.” As “technology becomes more powerful, distinctly human capacities become more valuable, not less.” Children “need a place designed for other aims, such as conversation instead of consumption.”

The “nation’s media capital is in many ways far less central to the national conversation than it used to be,” says Justin Fox. But in the “production of certain kinds of media — journalism in particular — New York is more dominant than ever.” The “New York-ification of media has for the most part continued to grow.” The “journalists who remain are increasingly concentrated in a city that, while wonderful, is utterly different from most of the rest of the country.”

After “years of pandemic disruption, writers’ strikes and uncertainty, theatrical exhibition is finally recovering.” Americans “were told that AI would become the dominant form of visual storytelling.” But “instead, audiences are buying tickets to films that demanded extraordinary effort to make.” They “are discussing performances, practical effects and directorial choices rather than marveling at how efficiently a computer assembled images.”

It is “correct to note that observational studies of annual flu shots suffer from various statistical biases,” say Christopher M. Worsham and Anupam Jena. Randomized trials “have earned their reputation as the ‘gold standard’ because they address a real statistical problem,” and “true randomized controlled trials remain the most rigorous form of evidence.” But this “can be drawn from the data we already have.” The “efficacy of flu shots in children is just one of thousands of questions we could answer this way.”

Almost three in 10 Britons now use AI chatbots to get health advice. And UK medical-policy experts are concerned that this could create confusion, undermine trust in GPs and other healthcare workers, and make it more difficult to take an informed decision about your health.

The warning, from The Academy of Medical Sciences, comes as Open AI rolls out ChatGPT Health in the US. It allows users to “securely connect” their medical records and wellness apps to “ground conversations” in their own health information, so that the bot can “take a more active role” in their health.

ChatGPT Health is not yet available in the UK but, with more than 300 million people worldwide regularly directing their health-related questions to ChatGPT, it could swiftly become a “democratising force in healthcare”, Tanzeem Choudhury, a health-innovation expert at New York’s Cornell University told CBS News. But there are definite risks and trade-offs. “Used well,” an AI tool such as this can “help direct people to trusted sources”, said Yvonne Doyle, a fellow of The Academy of Medical Sciences and former medical director of Public Health England. But it can also mislead “convincingly”.

‘Zero awareness of fallibility’

People have been using the internet to answer their questions for decades, but the “danger” with an AI chatbot is that it responds with “fluent, emotionally convincing paragraphs” and “remembers context”, making it “sound more ‘human’ than many humans”, said Celina Cartoto and Anthony Kelly on RTE. Yet it has “zero awareness of its own fallibility”, always providing an answer, “even when one doesn’t exist”. People need to remember that, though it “speaks like a doctor, listens like a therapist and remembers like a friend”, it is actually “none of them”.

We know that all AI chatbots can “hallucinate” and provide “misleading, inaccurate or even dangerous” information, said CBS News. Open AI has been careful to state that ChatGPT Health is designed to support, not replace doctors, but it has not responded to questions about whether it is “equipped to recognise when to advise a user to seek help from a medical professional”. It seems that “onus is on the user”.

Even before the rollout of the Health feature, there were indications that users could become dangerously reliant on ChatGPT for medical advice. Last month, a 55-year-old US pastor sued OpenAI, claiming its bot “brought him to the brink of death”, by “repeatedly and insistently” misdiagnosing his symptoms of near-fatal pulmonary embolism, said the BBC. An OpenAI spokesperson told CBS News that “ChatGPT is not a doctor and should never be a substitute for medical care, diagnosis or treatment”.

AI can be a “useful educational tool” for health information, said Leana Wen, an emergency doctor in the US, and a clinical associate professor at George Washington University, told CNN. It can “explain medical terminology” and “compare treatment options at a high level”, helping “people prepare questions” for their doctor and be “more engaged” in their care. But “it has important limitations” and “should not replace clinical judgement” by a medically qualified human.

Privacy concerns

There is also the question of privacy. How risky is it to share so much of your individual medical information with an AI tool, such as ChatGPT Health? Open AI has said that Health has “enhanced privacy” and encryption, and that conversations used in the Health tab won’t flow into non-Health chats. But it’s no accident that Health has not yet been rolled out in the UK, or the EU, where data protection and digital privacy laws are stricter than in the US.

“If you are providing data directly to a technology company that is not providing any healthcare services, then it is buyer beware,” Bradley Malin, a biomedical informatics expert, told Time. OpenAI says it will protect your data but “what exactly does that mean”?

It all comes down to whether or not “you trust OpenAI to keep to its word”, Robert Wachter, a medic who has written extensively about AI and healthcare, told the magazine. OpenAI does have “really strong corporate interest in not screwing this up”. Its brand is “dependent” on the user “feeling comfortable” in sharing their information, and any sort of data breach would end that trust.

The end of doctors?

The increasing use of AI programmes for health queries is becoming “existentially threatening” for medics, Jonathan Chen, a doctor at Stanford University Medical Center, told The New York Times. What is our purpose going to be now? Should we “get out of the way and let a computer take over”?

Not for a while yet, Lee Schwamm, associate dean for digital strategy and transformation at Yale School of Medicine, told the paper. And that’s because chatbots can’t yet think critically enough about the health information people are providing – and more importantly, not providing – them with. AI is “really good at matching patterns and making predictions”. But it can only do so “based on the data that it is given about the patient. It has no way to extract” what may be crucial further information itself.

Besides, patients still need a human connection. If you’re going to be told you have a serious health issue, or even how much longer you have to live, “you want to look someone in the eye”.

While the jury is still out on whether diet and zero-sugar drinks are really better for your health than sugary sodas, a recent study has found that the artificial sweeteners they use may have one very unintended side effect: memory loss, particularly among younger consumers. But even though the study found a significant link between artificial sweeteners and memory issues, experts say this is still only a correlation, not causation.

What did the study find?

Several widely used artificial sweeteners may be “associated with faster declines in memory and thinking skills over time,” according to the study published by the American Academy of Neurology. It followed 12,772 adults in Brazil for about eight years and examined their intake of seven sugar substitutes: aspartame, saccharin, acesulfame K, erythritol, xylitol, sorbitol and tagatose. These are “frequently added to ultra-processed products, including flavored water, soft drinks, energy drinks, yogurt and desserts marketed as low in calories.”

Researchers found that the people who consumed the highest amount of artificial sweeteners “experienced a 62% faster rate of cognitive decline than those with the lowest intake,” said USA Today, a rate “estimated to be comparable to about 1.6 additional years of brain aging.” People who were in the mid-range of consumption “experienced cognitive decline that was 35% faster than those in the lowest-intake group.” The memory loss itself was also most prevalent in study participants who were under 60; researchers “did not find the same association among participants older than 60,” said the study.

When it came to the amount of sweetener consumed, those in the “lowest consumption group averaged 20 milligrams per day, while those in the highest group averaged 191 milligrams per day,” said the study. Regarding aspartame, one of the most common artificial sweeteners, the “amount consumed by the highest group was roughly equal to the aspartame in one can of diet soda.”

What is the bigger picture?

This study suggests that sugar substitutes are not as good for you as their marketing makes them seem. “Low- and no-calorie sweeteners are often seen as a healthy alternative to sugar; however, our findings suggest certain sweeteners may have negative effects on brain health over time,” the lead study author, Dr. Claudia Kimie Suemoto of Brazil’s University of São Paulo, said in a press release.

This is not the only new study to suggest that artificial sweeteners have negative health effects; recent research published in the journal Current Atherosclerosis Reports showed that these chemicals are “linked to higher fasting insulin levels and a higher HbA1c — a measure of long-term blood sugar control,” said HealthDay. It also “found that people who consume more artificial sweeteners may have a higher risk of cardiometabolic conditions, including type 2 diabetes and heart disease.”

When it comes to memory issues, scientists are careful to point out that this research doesn’t necessarily mean artificial sweeteners cause lapses. The study “identified a relationship between sweetener intake and cognitive decline but could not determine whether the sweeteners caused the changes,” said USA Today. The data also “did not include every artificial sweetener currently used in foods and beverages,” and Suemoto emphasized that more research was needed.

It’s widely assumed that eight hours is the perfect amount of sleep but a new study found the “sweet spot” is a little less than that, said sleep specialist Dr Allie Hare in The Telegraph.

Getting it right matters because new research, published in Nature, found that “falling short, or exceeding” the “precise window” discovered by the research, is “linked with poorer brain, heart and immune health”.

What did the research say?

People who got between six hours 24 minutes and seven hours 48 minutes of sleep a night were found to have better functioning immune systems, brains and hearts, according to researchers at Columbia University Irving Medical Center.

This ideal amount of sleep was associated with less ageing, as measured by organ-specific biological clocks. Duration alone doesn’t cause organs to age faster or slower, but the findings do suggest that insufficient or excessive sleep may be “markers of poorer overall health across the body”.

Is it different for men and women?

There is also a gender factor because women “seem to do better with a little longer”, Marie-Pierre St-Onge, a professor at Columbia University, told The Washington Post. They need “15, 20 minutes” more sleep, which reflects the “slightly longer” sleep duration reported by the “general population”, which “tends to be slightly longer in women than men”.

Previous research found that sleep is “largely linked to ageing and the pathological burden of the brain”, said Junhao Wen, an assistant professor at Columbia and lead author of the study. But the new research "goes further” and shows that “too little and too much sleep” are “associated with faster ageing in nearly every organ”.

Should we all be getting seven hours?

There are a number of conflicting theories about how much sleep we need. According to individual needs theories, there is no single ideal amount of sleep, because genetics, age, health, activity level and even life circumstances influence how much sleep someone needs. Adaptive or evolutionary theories hold that the correct amount of sleep varies depending on factors such as season, workload, stress, illness and safety.

But we “might be overthinking it”, said Emma Beddington in The Guardian. Sleep is “important and fascinating for science to explore, but surely, for the rest of us”, it’s “best left mysterious”.

There’s “so little we can do” to reach the “ideal” amount of unconsciousness, so “knowing precisely how bad that is for us is unhelpful”.

Social media feeds full of hiking content and glorious views have contributed to a growing interest in the outdoors among young adults. But a worrying number of young people have also needed rescuing from mountainous regions.

Hiking influencers have become an “inadvertent source of inspiration” for their followers to take treks “without understanding the scale of the challenge” and that are “beyond their skill set”, said The i Paper.

Hiking posts can make the “toughest climbs look like a walk in the park”, said Kate Davis, from the Ramblers walking charity. While no influencer would “encourage novices” to take intermediate hikes without proper preparation, said The i Paper, not “everyone is honest” about their experiences.

For example, some content creators will “walk to a scenic spot” and “pose with merchandise” before heading back down, said Nige, who posts on TikTok as W33k3ndwanderer. This can “mislead viewers into thinking” that certain mountains with challenging inclines and scrambles are “easily accessible”.

This combination of misleading content and hikers unaware of factors like weather, technical clothing and time needed to complete a hike could be behind the rise in rescue call-outs.

‘Excitable explorers’

In the Scottish Highlands the number of “mountaineering incidents” involving the 17–25 age group has “nearly quadrupled since 2022”, said The Economist.

In England and Wales last year, 18 to 24-year-olds “kept mountain rescue services busy”, said The Times, with almost 400 incidents, “more than double the 166 in 2019”.

This trend of “excitable explorers” following in “influencers’ footsteps without fully understanding” what the hike entails has led to more rescue call-outs in the US, France, Italy and Switzerland.

Nathan Mburu, 24, a fitness influencer, told the BBC that he and his two friends being “overconfident” and “under-prepared” led to them getting into difficulty on Crib Goch in north Wales last year. The weather conditions quickly turned a “manageable day into something extremely dangerous”, resulting in the group being stuck on a ridge waiting nearly six hours for a rescue team to reach them.

Last year, nearly “a quarter of rescues” in England and Wales were the result of “slipping or tripping”, with common injuries being to the “ankles, lower legs and head”, said The Times. Almost “one in 10 incidents” was because of “poor equipment” and around 20% were due to “severe weather conditions”.

While it’s “great to see more young people going outdoors”, the question is how to make sure every hiker is prepared for the journey ahead. Since people “rarely use maps and compasses”, some parks are “developing signage with common routes”, said Nick Phillips, from Mountain Rescue England and Wales. An initiative will allow people hiking in the Lake District, Peak District and Wales to “scan a QR code” and “upload a map” on to their device with the route “they need to follow”.

‘The drug policy debate’s common ground: better treatment and recovery’

Jim Crotty at The Hill

Few “public policy debates are as polarized as drug policy, which is often framed around two competing visions — prohibition and decriminalization,” says Jim Crotty. Both are “passionate about their positions, and both make valid arguments,” but they “frequently overlook the same prerequisite for success: a system capable of meeting the country’s growing demand for addiction treatment and recovery services.” The U.S. “must help promote careers in treatment and recovery through more competitive pay, streamlined education and licensing pathways.”

‘AI can fuel biological weapons. We must harness its power for defense.’

Annie Jacobsen at The Guardian

AI can “help bad actors generate recipes for biological weapons” but also “track disease outbreaks and deliver critical public health information to millions of people,” says Annie Jacobsen. The “question is not whether AI can do catastrophic harm in the realm of biological sciences — it most certainly can — but whether public health officials can figure out how to deploy AI as a defensive tool faster than malicious actors deploy it as an offensive one.”

‘Joint European response to wildfires is essential’

Le Monde editorial board

The “flames currently devastating much of Western Europe are the latest, and dramatic, manifestation of climate change driven by human activity,” says the Le Monde editorial board. Beyond France and Spain, fires are “raging across Germany, Italy, Ireland, Scotland and the Netherlands,” and the “map clearly shows that any response must be coordinated at the European level.” The “increasing frequency of extreme weather events has forced both rapid adaptation and a global rethinking of how to respond.”

‘We need more therapists. They need more power.’

Isabel M. Perera at USA Today

Americans “need therapy now more than ever before,” but if “you’ve tried to find a therapist recently, you know it’s tough,” says Isabel M. Perera. The “people we rely on to help us cope with life’s hardest moments are themselves unsupported.” Weak “union representation makes it difficult for them to negotiate fair pay” and “advocate for better working conditions.” From “rehab centers to school counselors, the entire mental health ecosystem suffers from underinvestment and fragmentation.”

“Overlooked and underfunded” adult social care has become “the Cinderella service of our wider welfare system”, said Labour List. Now Andy Burnham, whose father has Alzheimer’s and lives in a care home, has told the BBC that he will put “whatever political capital I have” into fixing it.

He is not the first prime minister to vow to tackle the issue. But “successive governments have come undone when faced with the tricky reality” of adequately funding state support to help older people live safely and independently, said The Times.

What did the commentators say?

There have been 22 botched attempts to the reform the English adult social care system in the past 30 years. And those successive failures carry “a heavy political cost”, said Chris Smyth in the Financial Times: long-term underfunding has made pay and conditions in the sector so unattractive to British workers that “visa rules were loosened after Brexit” and care workers arriving from abroad became “the single biggest reason why net immigration to the UK rose to all-time high”.

Now, as Britain’s “demographic centre of gravity” tilts towards retirement, social care is reaching its “most painful financial pinch point” yet, said The Telegraph's editorial board. In 50 years, more than 25% of the population could be over the age of 65, according to the Office for National Statistics. The “best solution” for funding social care on that scale would be an “insurance-based system, where Britons would be encouraged to pay into a fund that would cover their own care in old age, should they need it”.

But Burnham has said social care should be delivered “on an NHS basis”. This implies “a public service free at the point of delivery and funded by some form of taxation”, said The Guardian’s editorial board. When Burnham was health secretary in 2010, he proposed a “national care service” to be funded by a deferred levy on dead people’s estates. Other options could include “a new form of social insurance” or “a combination of private and state payments”.

A more “ambitious” solution would be take responsibility for funding social care away from local councils, whose “revenues don’t map neatly on to local care needs”, and simultaneously reform council tax as a central tax that better reflects current property values and generates revenue for a national social care service, said Ben Zaranko in The Observer. That would “create losers, be complicated and take time but the course of true radical social care reform never did run smooth”.

What next?

Burnham is scheduled to deliver a speech on adult social care on Wednesday. In it, he will “stop short of unveiling” any concrete plans, said the BBC, instead announcing that he is speeding up Louise Casey’s independent review of possible solutions for the system.

Yet “the veteran Whitehall troubleshooter on whom Burnham is relying to come up with answers” has already warned there is no quick fix, said the FT’s Smyth. Earlier this month, she said “we cannot keep pretending that a few tweaks will fix adult social care, or attempt major reform without the public’s backing”.

Scientists are testing the “surprising theory” that “splitting sleep into two separate blocks” may be “the most effective sleep pattern for people working through the night”, said the BBC.

Better management of insomnia

Biphasic sleep means two distinct sleep periods in 24 hours instead of one. Researchers suggest it may be a more natural rhythm, even if the biological reasons for it are still being debated.

The concept has “captured the interest of many today”, said MediaFeed, and some individuals are “experimenting with segmented sleep patterns”. Its supporters say the benefits include “improved restfulness and better management of insomnia”.

During pre-industrial times people often slept in two blocks. Roger Ekirch, a historian at Virginia Tech, found that sleeping in two halves was the “predominant pattern” in the Western world until the mid-19th century. A “typical family” would “go to bed around nine, wake naturally after midnight for an hour or so – for prayer, chores, conversation – then sink back into what they called their ‘second sleep’.”

This changed when artificial light transformed the “economics of the night” and gas lamps “began lighting London’s streets in 1807”. As a result, “people stayed up later, the gap between the two sleeps narrowed and eventually closed”.

‘Dubious’ findings

The shift to a single period of sleep came at the time of the Industrial Revolution, as people changed to new work schedules, which were dictated by “mechanised time”, said MediaFeed.

But Ekirch believes the old approach hasn’t fully disappeared because the prevalence of “middle-of-the-night insomnia” represents a “persistent echo, a relic of this earlier pattern of sleep”.

A study in 1992 sought to discover whether, without industrialisation, humans would have remained natural biphasic sleepers. It limited participants to just 10 hours of light per day and found that they naturally shifted into a biphasic sleep pattern.

But the experiment drew criticism. In 2023, Niall Boyce wrote in the journal Medical History that its findings were “dubious” and suggested participants were simply restless.

Disrupted sleep, whether by working night shifts or insomnia, does have health implications. When we sleep, “our brain consolidates the memories of the day, processes emotions, and solves problems that defied it in the waking hours. It also strengthens immune defences and repairs muscle tissue”, said the BBC

So for those struggling to get enough sleep, “it’s not solely about being tired, but potentially about repeatedly disrupting a system that's doing far more behind the scenes than many people realise”.

Some experts have warned that biphasic sleep could have health risks, including from disruptions to circadian rhythms. Existing research on the topic is “fragmented” because some studies treat biphasic sleep as “one long sleep plus a brief nap”, but others “count only two equal periods”, so there is “no agreed definition”.

Spring forward, fall back — that old rule of thumb for resetting clocks at the start and end of daylight saving time may soon be a relic of the past, as the House of Representatives last week overwhelmingly supported a bill to make the time change permanent. And President Donald Trump has expressed his support. After all, people like later sunlight hours. But keeping the clock on summer hours could have negative ramifications.

‘Hidden consequences’

Americans are “tired of the biannual time change,” and making daylight saving time permanent is a “commonsense reform that will improve everyday life for millions,” bill sponsor Rep. Vern Buchanan (R-Fla.) said in a statement, per The Hill. Trump agrees. Passing the bill would be a “very nice WIN for the Republican Party,” he said on Truth Social. But there would be “hidden consequences” to year-round daylight saving, said Axios. Under the reset the “sun won't rise until 8 or 9 a.m. in the winter,” leaving “millions of children” and commuters to start their days “in the dark.”

There would probably be health consequences too. Morning sunlight is “key to maintaining our circadian rhythms” and “overall health,” said The Washington Post. “Circadian misalignment” can cause lost sleep, which in turn is connected to “obesity, Type 2 diabetes, cardiovascular disease, mood disorders” and other health challenges. Americans “would be misaligned all year long,” Vanderbilt University’s Beth Malow said to the paper.

The change would disrupt the daily prayer practices of Orthodox Jews, said NPR. Some prayers “can only be said communally” and are often performed “every morning before heading out for work or school.” The change would be a problem for a “synagogue that has had a morning prayer service for 100 years” if it cannot muster enough of the congregation to “show up at the prayer time close to 9 o'clock because they have jobs,” Rabbi A.D. Motzen, national director of government affairs for Agudath Israel of America, said to the outlet. “Some Muslim prayers and religious observances” would also be affected, said Axios.

Airlines “could take up to two years” to adjust their “complex scheduling” to permanent daylight saving, said CBS News. The shift could affect “crew and aircraft positioning” as well as “domestic and international connectivity,” trade group Airlines for America said in a statement. Trucking and railroad companies that are “also timetable dependent” would face challenges as well, said CBS.

‘Abandoned prematurely’

Congress authorized permanent daylight saving in 1973 to save energy during the oil crisis, said The Independent. The project was “abandoned prematurely” amid concerns about “children and criticisms from the construction and agricultural industries.”

Permanent standard time might be a healthier alternative, said Yahoo News. Stanford University researchers determined that sticking to the regular clock all year would result in “300,000 fewer strokes and 2.6 million fewer people with obesity.” People need “more morning light and less evening light” to have a balanced day, Stanford University’s Jamie Zeitzer said to the outlet.

What happened

More than 1,000 people have died of Ebola in Congo, in the fastest-growing outbreak on record, African health officials said Wednesday. Congo’s Ministry of Health said 2,536 cases have been reported since this outbreak was declared May 15. There are no approved vaccines or treatments for the Bundibugyo virus responsible for the outbreak.

Who said what

“These are people dying” because “we don’t have vaccines, we don’t have medicine, we don’t have funding,” Dr. Jean Kaseya, head of the Africa Centers for Disease Control and Prevention, said at a health summit in Ghana. In the worst outbreak to date, which killed more than 11,000 people between 2013 and 2016, it “took about eight months from the first case to reach 1,000 deaths,” The Associated Press said. The current outbreak in Congo appears to be “spreading faster than health officials can track it.”

What next?

An Ebola vaccine from Merck licensed to target the Zaire virus could also offer some protection against the Bundibugyo species, according to a paper published Wednesday in the New England Journal of Medicine. The World Health Organization has “expressed lukewarm support” for testing the vaccine in Congo, Stat News said, but Bundibugyo-specific vaccines are “still months away” from clinical trials.

‘This is why our fresh produce keeps making us sick’

Timothy D. Lytton at The New York Times

While “cases of cyclosporiasis have reached a new high this year, the parasitic infection has spread in recent summers, too, abetted by warmer weather and higher consumption of fruits and vegetables,” says Timothy D. Lytton. To “break the cycle of infection, the fresh produce industry has to step up its efforts to prevent contamination on farms and better sanitize food.” The government also “needs to identify outbreaks more quickly so that contaminated food can be removed from store shelves.”

‘The new college virtue isn’t about if you cheat, but how well’

Natalie Sandoval at USA Today

At colleges, AI “makes cheating easier, certainly,” says Natalie Sandoval. But its “rise is downstream from a cultural shift in higher education.” Americans are “witnessing a move away from a culture that valued honor and integrity (think of the social conditions that once made ‘a man of his word’ mean something) toward one where ambition and prestige are the only markers of worth.” To “be a striver is to be concerned with the appearance of prestige above all else.”

‘The attack on workers begins and ends with Black women’

Black women have “always been the backbone of the American economy,” say Anna Gifty Opoku-Agyeman and Rep. Ayanna Pressley (D-Mass.). In 2025, “thousands of Black women left or lost their jobs, with college-educated Black women and Black women in the federal workforce being disproportionately impacted.” What is “happening to Black women in the workforce is a harbinger for every worker and family in America,” a “perfect storm of this administration’s attacks on workers’ rights, equal pay and the workforce.”

‘“The Odyssey” will overwhelm you — and not only with spectacle’

The “movie industry appears to have been turned entirely upside down this year” as big-budget films have “dramatically underperformed,” says Will Leitch. This is “why there remains, truly, no one like Christopher Nolan,” who has “more on his mind than just spectacle.” His new film “The Odyssey” is “about the hubris of man, about how the more we convince ourselves we have conquered nature and the gods, and believe that we no longer need to look to history.”

What are peptides?

These short chains of amino acids are found naturally in the body and act as useful messengers, telling cells when to repair damaged tissue, produce hormones, reduce inflammation, and more. Scientists have turned a number of peptides into safe and effective drugs, including insulin, which moves sugar from blood into cells, and GLP-1 (the P stands for peptide), which helps regulate appetite and is used in weight-loss medications such as Ozempic. But a growing number of Americans are now taking peptides that, unlike those drugs, haven’t undergone a rigorous testing and approval process.

Administered via self-injection, these chemicals are claimed to result in thicker hair, increased libido, greater muscle mass, better skin, heightened focus, and more. Their seemingly miraculous properties have been praised by tech CEOs, podcaster Joe Rogan, and celebrities such as Gwyneth Paltrow, Jennifer Aniston, and Kim Kardashian, who says her daily regimen “changed my life.” But many doctors are alarmed by a craze that has thousands of people injecting themselves with substances of dubious origin and whose long-term effects are unknown. “It’s unfounded and reckless,” said Eric Topol, director of the Scripps Research Translational Institute.

How big is the industry?

Investors believe it’s a $1-billion-to-$3-billion-a-year market, but hard figures are elusive, because most peptides are sold on the quasi-legal gray market. Some are prescribed by doctors and dispensed by compounding pharmacies, which produce tailored medications. Others, which are legal to buy but not approved for use in humans, are sourced from Chinese labs and labeled “for research purposes only.” According to U.S. customs data, imports of Chinese hormone and peptide compounds hit $328 million in the first nine months of 2025, double the total for the same period of 2024. The wild success of GLP-1 drugs, which raised awareness of peptides, has partly fueled the boom, along with growing interest among the wealthy in biohacking—using regimens and supplements to improve the body’s performance and longevity— and glowing testimonials from social media influencers and peptide converts. “I hear it all day, every day: ‘This changed my life,’” said Amanda Kahn, a New York City–based doctor nicknamed the “peptide princess.”

Why do people take peptides?

For a legion of reasons. Proponents of GHK-Cu, a peptide found in human plasma, say it boosts collagen production and improves hair and skin. NAD+, touted by Paltrow as “one of my biggest wellness tools,” is claimed to benefit energy levels and memory. Many peptide fans talk about the makeup of their “stack,” or regimen of daily shots. Combine BPC-157 and TB-500 and you get the Rogan-touted “Wolverine stack,” named after the self-healing Marvel Comics mutant superhero. Iván Pol, a celebrity facialist, says a daily stack including GHK-Cu and BPC-157 has raised his energy, dropped his cholesterol, and lowered his body fat. Hassan Sleiman, a 45-year-old roofing contractor in Michigan, claims a regimen of seven peptides has eased body pains and boosted his vitality. At the University of California, Santa Barbara, says 22-year-old student Ryan Roberts, “everybody does them.” The long-term health risks of this experimentation are not yet known, but doctors are worried about higher cancer risk.

Can peptides increase the risk of cancer?

A recent study by University of Utah researchers found BPC-157 could promote the growth of tumor cells; TB-500 has been shown to speed tumor growth in lab animals. Doctors note that none of these peptides have scientifically proven benefits. People taking them are “becoming lab rats,” said Adam Taylor, a professor of anatomy at Lancaster University in the U.K. Users, even enthusiastic ones, have reported side effects including hair loss, blurred vision, rashes, and dizziness; two women who got peptide injections at an antiaging festival in Las Vegas last year were hospitalized with swollen tongues, elevated heart rates, and breathing trouble. Adding to doctors’ worries are concerns about purity and dosing, because users typically buy from websites selling unregulated Chinese product— some of which comes from plants that previously produced the deadly opioid fentanyl. Irregularities and contamination are common. Still, one high-profile peptide enthusiast wants to make it easier to get peptides: Health Secretary Robert F. Kennedy Jr.

What is Kennedy doing?

A self-declared “big fan” of peptides, he has pledged to end their “aggressive suppression” by the FDA. Under former president Joe Biden, the agency classified 19 peptides as unsafe and barred compounding pharmacies from producing and selling them. Later this month, an FDA advisory panel will meet to discuss seven of the chemicals, including those in the Wolverine stack, and issue recommendations. Since at least seven of the panel’s 14 members have ties to the peptide industry or clinics promoting them, it’s expected they’ll advise removing the restrictions—even though FDA scientists in June recommended against doing so, citing insufficient evidence on the peptides’ effectiveness and safety.

What will happen if the ban is lifted?

It will likely set off a multibillion-dollar gold rush among potential sellers. Among those poised to profit is the San Francisco-based telehealth firm Hims & Hers Health, which last year acquired a peptide-manufacturing facility in Menlo Park, Calif.; the company’s stock price spiked nearly 50% in April in anticipation of possible FDA action. Kennedy and other proponents say removing the restrictions will boost production at reliable, FDA-inspected facilities and open the door to the research critics say is lacking. But critics fear the FDA’s stamp of approval will simply legitimize the use of unproven substances whose dangers may only become apparent in coming years. “We’re all holding our breath a little bit,” said Peter Koshland, who teaches clinical pharmacy at UC San Francisco, “and just hoping that nobody gets hurt.”

What happened

U.S. health officials have linked an ongoing cyclosporiasis outbreak to iceberg lettuce from Mexico that was sent to Taco Bell locations across five states. The supplier has not been officially named, but “two individuals familiar with the inquiry” told The Washington Post the company is Taylor Farms. At least 1,645 cases of the parasitic infection, which can cause explosive diarrhea, have been confirmed as of Friday, most of them in Michigan.

Who said what

“Do not eat shredded iceberg lettuce from Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia,” the CDC said in a statement. Taco Bell itself has “taken immediate action” to “indefinitely” remove the lettuce from its nationwide supply chain, the company said in a press release.

What next?

The FDA said it had “increased screening at the border” for the “implicated” products and is working with the supplier to figure out if any contaminated lettuce remains on the market. Taylor Farms is “one of the largest producers of fresh lettuce and vegetables in the country,” serving many leading restaurant chains, The New York Times said. “Additional implicated brands, restaurants, retailers, or distribution channels” may yet emerge, the FDA warned.

What happened

Defense Secretary Pete Hegseth said Wednesday that the Pentagon will introduce testosterone screenings for soldiers over the age of 30. The screenings will be available to troops under 30 by request, and any soldier found to have lower testosterone levels will have the option to undergo hormone treatment. The new policy is designed so soldiers “have the right testosterone levels to operate at” their “absolute best,” Hegseth said in a video on X captioned “The High-T Department of War.”

Who said what

The secretary’s messaging “blends known science” on testosterone with “broader and less substantiated claims,” The Associated Press said. The new policy shows the secretary “takes direction from the far corners of the manosphere,” Rep. Chrissy Houlahan (D-Pa.), an Air Force veteran, told the AP. Hegseth “did not address” whether the “thousands” of women who “serve in frontline combat roles” would also be “subjected to hormone testing,” Politico said.

What next?

The screenings will be “conducted annually as part of service members’ periodic health assessments,” said Task & Purpose. But Hegseth has not disclosed when the screenings will begin.

What happened

Health officials are investigating whether restaurant chain Taco Bell “played a role” in the ongoing multistate outbreak of cyclosporiasis, The Washington Post said Tuesday. The foodborne parasitic infection can cause explosive diarrhea and is suspected to have sickened nearly 7,000 people across at least 34 states.

Who said what

Salad greens could be a “potential source for this outbreak,” Michigan’s health department said in a statement. But no “specific food item” has yet been confirmed as the culprit, said the U.S. Centers for Disease Control. The public is “largely flying blind” about what foods to avoid, CBS News said. Taco Bell said it has started “voluntarily and temporarily” removing some ingredients from select restaurants “as a precautionary measure.”

What next?

Taco Bell said it will continue to “closely monitor the situation and follow the guidance of public health authorities.” The CDC is analyzing lab data “to find a signal connecting the cases,” said Gwen Biggerstaff, deputy director of the CDC’s division of foodborne, waterborne and environmental diseases. Reports of new cyclosporiasis infections will likely continue through August, she added.

Data from more than 747,000 participants has been made available to scientists and doctors, creating an unparalleled genomic and electronic health record database “powering next-generation discoveries” in so-called “precision medicine”, the National Institutes of Health (NIH), the US medical research agency, has announced.

What is it?

Precision medicine, as defined by the NIH’s National Human Genome Research Institute, is an “innovative approach that uses information about an individual’s genomic, environmental and lifestyle information to guide decisions related to their medical management”.

Generally considered analogous to “personalised medicine” or “individualised medicine”, its goal is “to provide a more precise approach for the prevention, diagnosis and treatment of disease”.

What are the obstacles?

In theory, “therapies targeted to a person’s genetic make-up should be more effective and have fewer side effects”, said the BBC’s David Cox. But in practice, personalised medicine has in the past proved “erratic and expensive”. Another problem has long been that it “requires people to trust governments and companies with their genomic data, while the regulatory environment around medicines is ill-equipped to cope with therapies that are designed for just one person”.

That is the “paradox at the heart of precision medicine,” said NIH director Jay Bhattacharya. “To tailor treatments to individuals, you actually need very large populations to uncover the patterns that connect genetics, lifestyle, and the environment to health outcomes.”

What conditions could benefit from it?

NIH’s All of Us data has already fuelled more than 1,400 peer-reviewed publications across the US and around the world. Recent related breakthroughs range from a first-of-its-kind clinical genetic test predicting inherited risk of heart disease to the development of a low-cost prostate cancer risk model.

In a small-scale trial in California, people with early-stage dementia were given bespoke treatment plans targeting their personal nutritional deficiencies, ongoing infections and environmental exposures, which saw their symptoms improve.

A new “groundbreaking” genomic test could see millions of women with breast cancer spared debilitating chemotherapy, following the results of a trial that could “transform healthcare guidelines worldwide”, said The Guardian.

And in April, The New York Times reported on the story of KJ Muldoon, born in 2024 with an incredibly rare enzyme deficiency. In the space of just six months, a team at Children’s Hospital of Philadelphia and Penn Medicine designed a personalised therapy that was able to correct the single misspelled letter in his DNA using gene-editing technology. It was perhaps the “most important medical story of the decade”, said the paper.

AI modelling has also made analysis of huge datasets cheaper and more efficient. A recent study in the Annals of Medicine and Surgery suggests this is already having an impact on a range of critical specialities, including cardiology, infectious diseases, and oncology where machine learning models are able to analyse new sets of biomarkers so enabling “ultra-targeted therapies that strike tumour-specific mutations with remarkable precision”.

Even in psychiatry, AI is increasingly being used to predict treatment resistance for antidepressants well in advance. “This is the future of tailored, bespoke medicine,” said Forbes.

What happened

Sen. Mitch McConnell (R-Ky.) revealed Sunday that a fall at his Washington home last month led to a hospital stay. His announcement ends a “weekslong silence” that had “spurred speculation about his condition,” The Wall Street Journal said.

The 84-year-old senator said he briefly lost consciousness after the incident but did not break any bones or suffer a concussion, stroke, heart attack or other serious injury. He was later diagnosed with a mild case of pneumonia.

Who said what

McConnell acknowledged the delay in explaining his condition, saying in a statement that “folks of my generation often hesitate to share the vulnerability that comes with growing older.” McConnell’s injuries were “minor” and he “responded rapidly” to pneumonia treatment, his attending physician said. The Kentucky senator “has faced a string of health concerns in recent years that have caused some to question his ability to serve in the legislature,” The Hill said.

What next?

McConnell said he remains focused on completing his Senate work before retiring when his current term ends in January.

The series of heatwaves “afflicting” Europe this summer have been the “worst ever”, said The Guardian. Cities have become practically “unliveable” and higher temperatures are “further exacerbating” socioeconomic and economic divisions.

The unfortunate consequences of the current heat for many in the UK are “disturbed sleep and sticky days in the home office”. But around the world, high temperatures often exacerbate gender inequality, and women, particularly in low-income families, are “at the sharp end”.

Why are women more affected?

Women are more at risk of health complications during a heatwave for two main reasons, Dr Nighat Arif, an NHS GP who specialises in women’s health, told the BBC. First, women respond differently to men in the heat – they sweat less and start sweating at a higher temperature. These thresholds make it harder to “quickly shed heat” and fewer visible indications mean women can find it hard to judge how much their “bodies are under burden”.

The second reason is hormone regulation. Levels of oestrogen and progesterone shift “most substantially” during the menstrual cycle, perimenopause, menopause, pregnancy and while breastfeeding. This can knock the brain’s temperature regulation systems “out of kilter”, said Dr Arif.

Periods may feel more uncomfortable, while hot flushes and night sweats are more likely for perimenopausal and menopausal women. A recent study published by The Lancet suggested that heat stress may “increase the likelihood of adverse outcomes for the mother and child, particularly in higher-risk pregnancies”, said the BBC.

How does this present itself socially?

“How people experience heat is often gendered” and “socially and culturally determined”, said researchers Febe De Geest and Sergio Jarillo on The Conversation. In domestic settings, particularly across Africa, Asia and Oceania, women are forced to spend more time indoors in “poorly ventilated homes”, acting as primary caregivers. In Bangladesh, Cambodia and Nepal, heatwaves have also been linked to increases in child marriages: “struggling families force unions on their daughters to ease financial stress and reduce household costs”.

In workplace settings, research shows that women are sometimes required to wear more clothing for religious reasons and tend to receive “inadequate sanitation”. So they are likely to drink less to “avoid using unhygienic toilet facilities, leading to dehydration and further health problems”. These factors are not “trivial inconveniences; they compound heat exposure in ways that shape how women experience hot weather”.

Even in countries typically associated with better provisions for the heat, there is a “seasonal upswing in violence associated with hot weather”, said The Guardian. This could be due to the “temperature-aggression theory”, where hot weather increases “discomfort, frustration, impulsivity, and aggression, all of which make violence more likely”, or could be linked to greater alcohol consumption, which in turn “increases the opportunities for interpersonal conflicts and subsequent violence”.

Depressingly, it only takes “fairly small shifts” in temperature to increase the likelihood of domestic violence, particularly for the most vulnerable, said the European University Institute. A 1C rise in daily temperature is associated with “approximately a 2.7% increase in domestic violence reports”.

And in disadvantaged areas the effect is “much more intense”, due to more crowded living arrangements, lower cooling capacity and lower access to outdoor spaces. “Each degree of additional temperature is associated with up to a 50% larger relative increase in domestic violence incidents compared to richer areas.”

What can be done?

In practical terms, during periods of extreme heat it is important that women drink “least six to eight cups of non-alcoholic, non-caffeinated, transparent-liquid drinks” to help with temperature regulation, Dr Anisha Patel told ITV. Above all, women should continue to take prescribed medication as normal, including HRT or other drugs designed to help with the menopause.

Across the world, women are “already adapting creatively, and often without institutional support” to improve their situation, said De Geest and Jarillo on The Conversation. In Ahmedabad, India, women have painted their roofs white and used “coconut husks and paper waste” to make the structures cooler, and in Jakarta women have “established shaded communal areas that function as informal cooling centres”.

Policymakers need to realise that women suffer on many fronts, not just in biology but across “culture, power and intersections of class, caste and migratory status”. Their suffering is “largely invisible” to those heading climate responses.

Making sure women can cope with the heat is “not a woman’s problem”, Dr Arif told the BBC. “This is a societal problem. If we get it right for women, we get it right for everyone.”

All over the world, a growing number of late-in-life mothers are facing overlapping symptoms as they deal with postpartum challenges while also entering the perimenopause period. With so little research available on either condition, women are turning to each other to parse their experiences.

Fighting two battles at once

Last year in the United States, the number of births among women ages 35 to 39 was up by 90% since 1990, according to the Centers for Disease Control and Prevention. In 2023, births among women ages 40 and older exceeded teen births for the first time in the country’s history. As these numbers increase, more women are confronting the “bewildering convergence of two mind- and body-altering hormonal events,” The Washington Post said: the postpartum period and the transitional years of perimenopause marked by “hormonal instability” that can “wreak havoc for up to a decade before menopause occurs.”

There are specific struggles as more women experience postpartum and perimenopause simultaneously, Jessica Shepherd, an OB-GYN and the chief medical officer at the telehealth platform Hers, said to Self. Postpartum symptoms “can take upward of a year to resolve” following pregnancy. Meanwhile, perimenopause can arrive as early as your late 30s. With women waiting to have kids later in life because of “changing cultural norms and a boom of fertility medicine,” it is “no wonder even first-time moms” are becoming “more likely to hit perimenopause while postpartum.”

The symptoms can overlap because post-childbirth, estrogen and progesterone drop to their pre-pregnancy levels. In perimenopause, those same two hormones “tumble downward, often on a zigzagging path,” which can trigger “similar mental symptoms, like anxiety or a short fuse,” said Self. The picture “gets fuzzier in moms over 35,” who are both “more likely to be heading toward menopause” and may be at greater risk for postpartum depression.

Breastfeeding, which can cause prolactin and oxytocin levels to soar, also complicates the issue. When women are nursing, it can “create this pseudomenopausal state” due to low estrogen, which may cause “symptoms like vaginal dryness, low libido, hot flashes and night sweats,” OB-GYN Stacey Silverman Fine said to Self.

Women owed the ‘respect of more research’

In the medical community, there is a “dearth of knowledge” about the intersection of the postpartum and perimenopausal stages, Suzanne Fenske, an OB-GYN who specializes in perimenopause and menopause, said to the Post. This is only made worse by the fact that the United States “offers minimal postpartum care,” the outlet said. Women’s health concerns are often “systemically dismissed,” and “women have been socialized to downplay their experiences.” Thankfully, that is shifting, in part because physicians are more outspoken on social media and awareness is spreading to “mainstream pop culture.” Every time you turn around, there’s a “book that’s out about perimenopause or menopause” or a “popular TV show alluding to these changes,” said Fenske.

Within the “maelstrom of hormonal chaos,” many women point to one “meaningful bright spot,” the Post said. Postpartum and perimenopausal mothers are “finding one another” and “building a sense of connection around their shared experience.” Online forums and group chats can be a “lifeline for postpartum and perimenopausal moms” who might “otherwise feel alienated in spaces dominated by younger parents.”

With so much gray area in our knowledge of the overlap, it is of paramount importance to listen to and believe patients, OB-GYN Talat Uppal told the Australian Financial Review. Before we can help patients navigate these intersecting life stages, we have to listen to their concerns. With more women birthing after 40, “we need to really give them the respect of more research.”

A parasite capable of causing extreme diarrhea has been found in 18 states, with a particularly large outbreak in Michigan. Though the source of the infections has yet to be identified, experts recommend taking precautions with fresh produce and practicing good hygiene to reduce the risk of contracting the disease.

What is cyclosporiasis?

Cyclosporiasis is a form of food poisoning that comes from the parasite Cyclospora cayetanensis. It can cause “watery, and sometimes explosive, diarrhea and other stomach problems,” as well as a low-grade fever in some cases, said the Cleveland Clinic. Symptoms can start any time between two and 14 days after consuming contaminated food or water. The parasite is more common in tropical countries, but in mid-June, 145 cases were reported in the U.S.

“People became sick after eating food in the United States and did not report any travel during the 14 days before they got sick,” said the CDC. Those infected ranged from ages 5 to 86 years old, and though there have been hospitalizations, there have yet to be any deaths from the condition.

There has been growing concern about cyclosporiasis because Michigan, “which typically identifies about 50 cases of cyclosporiasis in a year, has reported at least 170 cases” in under two weeks, said CNN. There is “currently no evidence of a single, multistate Cyclospora outbreak linking all cases,” said the CDC. Instead, researchers are “working to identify various potential clusters and sources of illness in multiple states.” Though Michigan has had the most cases, Alaska, Colorado, Connecticut, Illinois, Florida, Georgia, Louisiana, Massachusetts, New Jersey, New York, North Carolina, Ohio, Pennsylvania, Tennessee, Texas, Virginia and Wisconsin have also had reported infections.

Investigators have yet to pinpoint the cause of the current outbreak, but the most likely culprits are “cilantro, basil, plants that grow and that you might put in a salad or use as a garnish,” or “strawberries, blueberries, melons, things that grow in fields,” David Freeman, a professor emeritus of infectious diseases at the University of Alabama at Birmingham, said to CNN.

What can be done?

Taking precautions is key to preventing illness. Cooked food is safer than fresh produce, as heat can kill the parasite. Washing produce can also help reduce the chance of ingesting the parasite. “Thoroughly washing hands and kitchen counters, as well as cutting surfaces, is important too,” but “bleach doesn’t kill the parasite,” said CNN. “Handwashing with soap and water and a follow-up with an alcohol-based hand sanitizer are safer bets.”

If you contract cyclosporiasis, antibiotics can help clear the infection. If not treated, “symptoms may last for a month or longer” and increase the “risk of severe dehydration and other complications,” said the Cleveland Clinic. “With proper diagnosis and treatment, most people feel better after a week or two,” but you “may still have occasional bouts of diarrhea for up to a month.”

The Trump administration has officially brought the Presidential Fitness Test back from the dead after it was discontinued in 2013, and Secretary of Health and Human Services Robert F. Kennedy Jr. is lauding it as a major step forward for children’s health. But some health experts aren’t so sure that the revitalized test will improve youngsters’ lives in a meaningful way.

‘Not much has changed’

The test, which was sunsetted during the Obama administration in favor of a different regimen called the Presidential Youth Fitness Program, is now back by executive order from President Donald Trump. But “compared to previous iterations of the test, not much has changed: It includes a timed run, an upper-body strength test and a core test, with benchmarks set by a child’s age and gender,” said Chelsea Cirruzzo at Stat News. Health experts worry that such a stringent “focus on specific physical activity benchmarks could turn some kids off exercise.”

The “worst experiences that people tend to report” from childhood fitness tests are “something having to do with embarrassment,” Matthew Ladwig, an assistant professor of integrative human health at Purdue University Northwest, told Stat News. Negative memories of exercise as a child are “associated with adult sedentary behavior” later in life, a 2018 study co-authored by Ladwig found. Embarrassment is a “leading indicator. A lot of people felt that with the old test, which, unfortunately, shares a lot of similarities with the new one.”

Others question “whether a fitness test alone will be enough to move the needle on physical activity and exercise,” said Mary Kekatos at ABC News. “When you think about a math test and English test, it’s private failure. If you don’t do very well on a test, the teacher knows and you know, but the rest of your classmates don’t know,” Jackie Goodway, a kinesiology professor at Michigan State University, told ABC. “But if you come in last in the mile run and everybody’s laughing at you, it’s public humiliation.”

‘A healthy nation can only exist if its citizens are fit’

Others believe that the physical promises of the Presidential Fitness Test outweigh any negatives. A “healthy nation can only exist if its citizens are fit,” and “policymakers are finally recognizing the problem,” said K. John Lee at The Oklahoman. The reimplementation of the exam comes at a time when many children cannot “pass a military physical fitness test,” and “whether or not a student ever serves in uniform,” that “should concern us.”

“Too many young people are spending less time moving and building healthy habits,” said Rep. Jeff Van Drew (R-N.J.) in a statement. Reviving the test will “give students a positive goal to work toward and make physical activity a bigger part of their everyday lives.” By “bringing back the Presidential Fitness Test,” said Kennedy in the same statement, America is “giving parents, schools and communities the tools to help children build healthy habits, strengthen their bodies and discover what they’re capable of achieving.”

On its own, a physical test would be more of a “performative gesture than a real public health campaign to tackle the childhood obesity epidemic,” The Washington Post editorial board said in an August 2025 op-ed, after Trump announced the test’s return. But a “focus on the health of America’s children is welcome, especially if it draws added attention to the need for more school time devoted to physical activity.”

New medicine can be found even in the iciest of locations. During an expedition to Antarctica, scientists discovered a species of sea squirt that may promise a new cancer treatment. The marine organism contains bacteria capable of producing a toxin that could eventually become a widely available drug. However, research still needs to be done on the species and bacteria before it can be tested on humans.

The dive

The cancer-fighting sea squirt, also called an ascidian, was first discovered 20 years ago and identified as a potential cancer therapy. The bacterium in the organism, Candidatus Synoicihabitans palmerolidicus, can “produce the metabolite palmerolide A, which kills melanoma cells without causing too much harm to healthy human cells,” said Discover.

Scientists have now conducted a second expedition to Antarctica to “better understand the compound and explore whether it could someday contribute to new therapies for patients battling melanoma,” said a news release by the University of South Florida. “Our expedition focused on determining where the ascidian’s melanoma-killing bacterium occurs and how widespread it is,” Sam Afoullouss, a postdoctoral researcher who participated in the dive, said in the release. “We also wanted to understand how it lives inside the organism and how that connects to the compounds linked to melanoma research.”

Sea squirts are “sac-like marine invertebrates that tend to live on sloped sea beds,” said the BBC. The ascidians found in Antarctica have “evolved over millions of years to cope with the harsh conditions there, producing chemical defenses that can deter predators and disease.” The discovered species was found at “depths between 60 and 80 feet, often along sloped or vertical seafloor surfaces where water currents are strong,” said the release. These “currents help deliver nutrients that sustain the organisms.” Such conditions allow for the organisms to be highly specialized.

The test

The researchers tested the sea squirt’s bacteria on melanoma cells in mice. “The good news is it didn’t kill the mice,” Bill Baker, a chemistry professor at the University of South Florida who led the first expedition and advised the second one, said to The Guardian. “It did kill their cancer, so we know it has the physiological properties to act like a drug.” The scientists are also analyzing the “quantity and distribution of palmerolide A, the bacterium, and the molecular target of palmerolide A,” Baker said to Discover. “These analyses will help us determine, for example, whether the ascidian and bacterium are working in concert, whether the bacterium is detrimental to the ascidian, or one of several other potential relationships between the two.”

Most FDA-approved drugs originated in nature, and Antarctica could be a rich source of new possibilities. While the sea squirt shows promise, the “pathway to producing a safe and effective anti-melanoma drug, with approval for use in humans, is long,” said The Guardian. It would “require a succession of strictly regulated and ever-expanding trials even after a drug was formulated.” Still, the knowledge gained from this expedition “could significantly advance the timeline.”

There may be a few sore heads and impeccably timed phone-calls to bosses in England this morning, after last night’s win over Mexico in the World Cup, but any football fans must be thankful they don’t live in Germany where workers will have to report to a doctor in person, to get a sick note on the first day they are ill, under sweeping new reforms.

The government is “tired of its workers calling in sick”, said the Deep Dive, but unions and family doctors are opposed to the new law.

What is Germany doing?

“The number of sick days is too high,” said Friedrich Merz, the German chancellor, announcing the plan. The government is “creating a set of tools that will enable those involved, both employees and companies, to correct this,” he added.

The “tough” new rules are “aimed at boosting Germany’s stagnating economy”, wrote Hans van Leeuwen, international economics editor of The Telegraph.

Although they will be “welcomed” by employers, they have “angered” the country’s “powerful trade unions”. The services sector union, Verdi, accused Merz of creating a “culture of distrust of employees”.

Doctors also have “opposed” the new system because they believe the new requirements will “swamp” GP surgeries with “unnecessary appointments”.

What are sickness policies like elsewhere?

In the Netherlands, employers are generally obliged to pay employees on sick leave 70% of their wages for up to two years. If that amount is less than minimum wage, then the employer must boost this to the minimum wage for the first year. Norway is even more generous: it provides up to a year of income replacement at 100% of salary (subject to an earnings cap).

Although the US is one of the richest countries in the world, there is no nationwide entitlement to paid sick leave in the US, so access depends largely on state laws, local ordinances and employer policies. This means coverage varies considerably. Only 14 of the 50 states have paid sick leave mandates in place, which means sick workers are often forced to rely on health insurance pay-outs to cover their wages.

In the UK employees who earn over £125 a week and are off sick for four or more days in a row, are entitled to £123.25 per week of statutory sick pay for up to 28 weeks. This equates to around 15% of the average UK weekly wage. Employees need to give their employer proof if they’re ill for more than seven days. Many employers have a sick pay policy which is more generous.

How many sick days do people take?

In 2025, 149 million working days were lost to sickness or injury in Britain – an average of more than four days per worker. On average, Americans take roughly one to three days of sick leave per year.

In Germany, workers take about three weeks, or 15 working days, of sick leave per year. This is lower than in France, but higher than Sweden, the Netherlands, Denmark, Poland and Italy.

Desperate to soothe symptoms caused by unbalanced hormones, women are turning to a TikTok trend that recommends combining allergy medication and antacids to treat conditions like PMS or menopause. Despite a lack of clinical evidence, experts say there may be a reason the cocktail is helping some people keep persistent symptoms at bay.

OTC relief

People who feel “extra rotten in the days leading up to their period” are finding relief from this TikTok-approved concoction, said NPR. The over-the-counter combo “helps to combat premenstrual blues,” leading participants to feel “less irritable and more energetic.” Others going through perimenopause and menopause reported that it “helps to lessen similar symptoms.” The drugs also went viral last year amid claims they helped manage symptoms of premenstrual dysphoric disorder (PMDD), where patients “experience depression and anxiety caused by premenstrual hormonal shifts.”

Some women struggling with “conditions marked by hormonal fluctuations” swear that the blend finally provides some relief, said People. It helps with “hot flashes, mood swings and sleeplessness often associated with these disorders.” The specific drugs most often “touted in this hormonal cocktail” are Allegra and Pepcid AC.

To date, there have not been any clinical trials testing the safety or efficacy of this trend. Those who are using the combo are operating in an “evidence-free zone,” Leigh Frame, the executive director of the Office of Integrative Medicine & Health at George Washington University, said to NPR. There is “no evidence that it does or doesn’t work."

However, experts agree there is a “plausible biological mechanism” for why some may be seeing benefits, said NPR. It has to do with histamine, a chemical released when you come into contact with an allergen, which triggers an inflammatory response. There is evidence that suggests “histamine also fluctuates with your menstrual cycle.” Estrogen, which stimulates the release of histamine, “ebbs and flows throughout the month,” while progesterone acts as a “sort of natural antihistamine.” But in the days leading up to your period, progesterone “takes a nosedive.” In perimenopause, too, the levels of both hormones “rise and fall rapidly, often erratically.”

Both allergy medication and antacids are histamine blockers that interact with different receptors throughout the body, said Mara Rivera, a psychiatrist who specializes in reproductive health challenges, to NPR. The theory is that this combination may help keep histamine in check, basically replacing the effect of progesterone. In some ways, the trend is a modern-day example of an old wives’ tale. Women have been “doing this forever, just talking to one another, and seeing what works,” Rivera said.

Feeling unheard

The popularity of the “DIY Allegra and Pepcid AC cocktail” stems in part from “women feeling like they are not being heard by their doctors,” said People. Women are “hungry to know more and to help themselves,” and they often “feel like they’re not being listened to,” Soma Mandal, the medical director of women’s health at Jersey Shore University Medical Center at Hackensack Meridian Health, said to People. It is important to “find someone who will listen,” who will “take complaints seriously” and who also understands that this is a “physiologic part of life and deserves the appropriate treatment.” If you are not getting that level of care with your current practitioner, “then it’s time to move on."

Experts are not against open discussion and the sharing of symptoms and potential remedies over social media. It is “great that we are asking these questions and bringing up these ideas,” because we “desperately need more research in midlife women’s health,” gynecologist Amy Voedisch said to Everyday Health.

‘The case against fireworks’

Char Miller at Time

“This year’s Fourth of July fireworks promise to be especially explosive,” but they have “negative consequences for our environment and our health,” says Char Miller. Climate change is “making landscapes more vulnerable to fire,” and fireworks also “pose other life-threatening challenges.” They “can degrade air quality for hours or even days.” For “people with asthma, cardiovascular disease, or other respiratory conditions, the toxic air presents genuine health risks.” Drone displays “are an innovative alternative with far fewer risks.”

‘Assailed by right and left, the Peace Corps continues to make an apolitical difference’

Jonathan Zimmerman at The Philadelphia Inquirer

Republicans have “proposed to eliminate funding for the Peace Corps,” but the organization “has also been the target of left-wing attacks,” says Jonathan Zimmerman. Neither side “believes that Americans can be a force for good in the world,” and that is “why the Peace Corps matters.” It is “based on the simple proposition that bringing different people together can help them thrive. And it’s a standing rebuke to cynics on the right and the left.”

‘Why the Arab League could not stop Israel’s genocide’

Rami G. Khouri at Al Jazeera

“Arabs are perplexed by why their governments and the Arab League have been so docile in the face of the Israeli genocide in Gaza,” says Rami G. Khouri. But Arab states “have never been able to harness their natural, human and geographic resources to become powerful, confident states that are not constantly manipulated.” They “rely heavily on non-Arab powers for financial, military, technological and other assistance that is vital for their survival; this deep dependence has diluted their sovereignty.”

‘The obesity curve finally bent. Now comes the hard part.’

Ashish K. Jha at The Boston Globe

GLP-1s “appear to have done what no public health effort could” for obesity, but “having a treatment is not the same as getting it to the people who need it,” says Ashish K. Jha. Obesity drugs “should be covered by health insurance.” Coverage “should be broad and clinically grounded. It currently is not.” Insurance companies can “build in lower-cost maintenance once a patient stabilizes, so the choice is not a $1,000 injection forever or watching the weight return.”

While postpartum depression is widely known as an issue that affects mothers, researchers are increasingly finding that it can be experienced by fathers too. Postpartum depression is often used as a shorthand for any perinatal mood disorder, which can include anxiety and OCD. Understanding how that manifests differently across genders could be key to getting men the help they need.

New parenting stress

Fathers are “at risk for the same things that mothers go through,” said Sheehan Fisher, a perinatal clinical psychologist, to The New York Times. About 10% of fathers develop symptoms like depression and anxiety during the perinatal period, which lasts from pregnancy through the first year after childbirth. That is about half the proportion of mothers who develop similar symptoms. Conditions in fathers could be more prevalent than assumed because “men may be less likely to seek help than women are and often have different symptoms,” said the Times.

Depressed dads are more prone to expressing aggravation, annoyance or even rage, Daniel Singley, a psychologist who founded a therapy center for men, said to the Times. Beneath those emotions, they are likely “feeling hurt, sad, afraid, ashamed, helpless, hopeless,” but “what we see externally is anger and irritability.” These feelings can also present with physical symptoms such as muscle tension or stomach pain.

Evidence suggests a relationship between “paternal employment, psychological status, history of maternal mental illness, first pregnancy, marital relationship” and paternal postpartum depression, researchers said in a 2021 study. Another major risk factor is a “prior history of depression in the man,” said Psychology Today. Men also “typically experience a decrease in testosterone levels during the woman’s pregnancy,” which can contribute to a higher risk of depression.

Postpartum depression in fathers is “real and affects a substantial number of fathers,” said Psychology Today. It can have “deleterious effects for the father, the mother and the baby.” Screening for PPD in men is “important and yet is underutilized.”

Seeking help

Men can go undiagnosed because they prioritize the mother’s concerns over their own symptoms, or because they have a “hesitancy to admit” that they are struggling, Fisher said to the Times. Nearly half of PPD cases in women start during pregnancy, with the first postpartum weeks considered a high-risk period. For men, the riskiest window is three to six months after babies are born, possibly related to the “infants’ growing needs and activity or to the mothers returning to work.”

The number one risk factor for paternal postpartum depression, though, is “maternal postpartum depression,” Singley said to the Times. There is “a lot of stress” because men “want to be supportive, want to be caregivers,” and the “system is set up, really, to support women,” Brett Biller, a psychologist, said to CBS News. As paternal PPD becomes more widely recognized, the availability of resources should increase as well. Whether it's “medication, talk therapy or both,” there is “nothing wrong with that,” Biller added. “Mental health difficulties are the same as physical difficulties, and there’s a correlation between the two.”

Men are sometimes taught that “seeking support for their mental health is a sign of weakness,” psychologist Adam Borland said to the Cleveland Clinic. “But it’s not.” If you’re living with male postpartum depression, “it’s the best step you can take to best care for yourself and your family.” Adjusting to a baby can be trying, but if your depressive symptoms persist for weeks, don’t hesitate to reach out for guidance.

There is “nothing shameful or embarrassing” about the condition, Borland said. Fatherhood is a “huge new job, with long hours and no pay and you deserve support.” Asking for help means you are “doing what you need to do so you can be the best man — and best dad — you can be.”

Alzheimer’s disease, a progressive brain disorder that gradually degrades a person’s cognitive and memory functions, is the No. 1 cause of dementia. There’s currently no cure, but according to a study published in the journal ACS Chemical Neuroscience, a new copper-based treatment may be on the horizon.

Clearing out

Alzheimer’s is “driven by the buildup of toxic proteins called amyloid beta,” said a release about the study. These proteins are usually flushed into the bloodstream through the blood-brain barrier. However, in those with Alzheimer’s disease, the “pumps doing the heavy lifting, called P-glycoprotein (P-gp), weaken significantly, clogging the drain and trapping the toxic proteins in the brain.”

A buildup of these proteins in the brain leads to memory loss and cognitive decline. But the copper-based compound Cu(ATSM), which has “anti-inflammatory and neuroprotective properties,” can clear them from the brain, said senior study author Joseph Nicolazzo in the release. It does so by “increasing the number and activity” of the P-gp pumps, said Newsweek.

The study is the first to show that Cu(ATSM) can boost the amount of P-gp pumps “by 24.1%, effectively linking the repair of the blood-brain barrier to a reduction in toxic proteins and improved cognitive function,” said lead study author Jae Pyun in the release. “Over 56 days, the treatment reduced toxic amyloid-beta by 42% and improved spatial learning by nearly 44%.”

Not just yet

Alzheimer’s disease is the No. 1 cause of dementia, accounting for about 60% to 80% of cases, according to the Alzheimer’s Association. The condition also worsens over time. In its early stages, “memory loss is mild, but with late-stage Alzheimer’s, individuals lose the ability to carry on a conversation and respond to their environment,” said the association. “On average, a person with Alzheimer’s lives four to eight years after diagnosis but can live as long as 20 years, depending on other factors.”

Cu(ATSM) improved the long-term spatial memory of mice, showing promise for future human clinical trials. The compound has also “already progressed to clinical testing for conditions like Parkinson’s and ALS,” said Nicolazzo in the release. However, “despite its promising results in animals, a pilot comparative analysis found that Cu(ATSM) provided no significant benefit to humans with ALS,” said Science Alert.

More than 7 million Americans 65 and older are estimated to be living with Alzheimer’s. By 2050, that number is projected to rise to close to 13 million, according to the Alzheimer’s Association. A drug that could prolong cognition and lifespan would be a game changer for patients and their families.

The disease itself is still full of unknowns. Alzheimer’s “involves the biological environment of the aging brain, including membrane biology, inflammation, vascular function, lipid metabolism and cellular resilience,” said neuroscientist Dayan Goodenowe to Newsweek. “So any single mechanism still has to be validated before we know whether it produces meaningful clinical benefit.”

The Department of Health and Human Services is moving to make adjustments to testosterone-therapy labels, reversing changes made over a decade ago that restricted availability for some men. With hormone drugs being hailed as yet another wellness drug, experts worry the requested adjustments could trigger a testosterone free-for-all.

Why is the HHS asking for revisions?

The Food and Drug ​Administration as of 2015 required testosterone therapy labels to state that the “safety and effectiveness of the treatment had not been ​established” in men with symptoms associated with idiopathic hypogonadism, an age-related condition “involving low testosterone levels without a known underlying cause,” said Reuters. Now the HHS is requesting that labels be revised to remove that statement. The HHS also wants to update information related to prostate cancer risk and revise warnings regarding enlarged prostates after reviewing new data and evidence on the safety and benefits of hormone therapy.

These updates could “pave the way for easier access to testosterone replacement therapy” for a wider subset of men, said CNN. During Men’s Health Month, the HHS is “putting science back at the center of men’s healthcare,” said HHS Secretary of Health Robert F. Kennedy, Jr in a press release.

What are the risks of lessening the barrier to testosterone therapy?

No matter the outcome of the suggested revisions, experts warn that patients should still have “in-depth talks with their doctors about whether testosterone therapy could be helpful for them,” and doctors should “complete thorough evaluations,” said CNN. Besides, taking a warning off a label “isn’t the same as saying every man should be on the medication,” Jamin Brahmbhatt, a urologist and men’s health expert at Orlando Health, said in an email to the outlet.

For a man who genuinely has low testosterone, the “benefits are real: improved energy, sex drive, mood, muscle and bone strength,” Brahmbhatt said of testosterone therapy. However, for those with normal levels that are just “chasing an improvement in health motivated by online influencers,” the risks “may not outweigh the benefits.”

While experts insist that testosterone is not just a lifestyle drug that “men take to build muscle and feel good,” it is “increasingly being marketed that way,” said Nature. Influencers and “podcasters such as Joe Rogan and his guests” have “sung the hormone’s praises” and “scores of testosterone clinics are popping up” globally.

People have always “wanted a fountain of youth,” said Landon Trost, a urologist, to the Houston Chronicle. Hormones, “since really the 1970s or even earlier,” were considered the magical pills to achieve that goal. Today, the hormone is “widely prescribed in ways that aren’t covered by insurance” and that don’t “always align with mainstream medical guidance,” said the outlet.

Relaxed scientific protocols and standards within the Department of Health and Human Services have led to an increase in clinics offering experimental stem cell treatments to parents of children with severe autism. Despite being technically unapproved by the Food and Drug Administration, parents are shelling out tens of thousands for treatments that claim to improve language and social skills and reduce problem behaviors.

Operating ‘beyond the bounds of FDA approval’

Although there is a lack of FDA approval and little evidence of its efficacy, stem cell treatments for autism are being steadily provided across the country. Children with autism “as young as 18 months old” are getting “unapproved stem cell treatments” at clinics in Florida, Texas and elsewhere, “part of a growing market operating beyond the bounds of FDA approval,” said The Guardian.

The procedure involves sedating a child before administering intravenous doses of millions of stem cells, “commonly derived from human umbilical cords harvested at birth,” said The Guardian. Sometimes the doctors providing the treatment have “no scientific expertise in autism or child development.” Instead, they have “entered the booming stem cell sector,” billing the procedures as “regenerative medicine” for children, “some of whom have severe disabilities.”

As stem cell clinics “multiply across America,” they are “finding an influential ally in the U.S. Health Secretary Robert F. Kennedy Jr.,” said The Guardian. Kennedy’s influence could lead to new policy, said Paul Knoepfler, a stem cell biologist and unofficial watchdog of stem cell clinics, to the outlet. The FDA has not taken action in the last 18 months. This could mean a “big change coming from the FDA very soon, backing off oversight of birth-related stem cells.”

Several clinics prominently cite an early Duke University study involving 25 autistic children that “suggested possible improvements following umbilical cord stem cell infusions,” said Trial Site News. But a “larger and more rigorous follow-up trial” involving 180 children failed to “demonstrate significant improvements in core autism symptoms compared with placebo controls.” Similar results emerged from a “placebo-controlled study conducted by Sutter Health.” This has led researchers to conclude that the “evidence does not currently support routine use of stem cell therapies for autism outside formal clinical research settings.”

Up until now, Americans seeking stem cell therapies for autism have looked abroad to places where they are approved and federally regulated or operating in grey areas. There is a flourishing multibillion-dollar industry of “stem cell tourism” in places such as “Mexico and Panama” and “as far afield as Abu Dhabi,” said The Guardian.

But most European countries limit the use of stem cell injections to clinical trials, and they are not an approved treatment for autism. In January, the Indian Supreme Court ruled that stem cell therapy cannot be used as a clinical treatment for autism spectrum disorder, making it clear it is “not only unethical but amounts to medical malpractice,” said Indian network NDTV.

When ‘hope outpaces evidence’

The biggest lesson from this story is “not political,” said Trial Site News. “It is human.” Parents seeking unsanctioned stem cell therapies are “not irrational.” Most are “navigating difficult realities” with “limited options and enormous responsibility.” The danger emerges when “hope outpaces evidence.” The appropriate response is “neither unquestioning enthusiasm nor reflexive dismissal” but rather “rigorous clinical research, transparent reporting, long-term safety monitoring and honest communication with families.”

After RFK promised to find a cure for autism last year, some people were “appalled and fearful,” clinical social worker Jennifer Cork said at Psychology Today. Plenty of families whose children require substantial support, however, were “relieved that someone in a position of power was finally talking about their struggles.” The issue is that these families “don’t need untried, expensive treatments.” They need “affordable therapies, respite care and adequate accommodations that they don’t have to fight for.” They also need Kennedy to “remember that autistic people are human beings, not lab rats.”

Infecting yourself with internal parasites doesn’t sound like the best way to feel better but scientists have “engineered” the genes of hookworms to deliver medicine – and “it’s just crazy enough to work”, said ZME Science.

US researchers have genetically modified hookworms to produce and secrete specific antibodies. This is a “first step” towards creating “living pharmaceutical factories” that can deliver therapeutic proteins “directly inside the host”, they said in their study, published in Nature Communications.

Internal leeches 

The hookworm has “spent millions of years perfecting how to assure long-term survival inside a human host, and how to get molecules out of its body and into ours”, said senior author Makedonka Mitreva, from Washington University in St Louis, on EurekAlert.

They are like an “internal leech”, infecting upwards of 400 million people globally, mostly in tropical regions, said LiveScience. As they latch on to the inner wall of the gut to feed on blood, they release “anti-inflammatory and immunosuppressant compounds to prevent the body from flushing them out”.

Scientists have already noted that this “cocktail of compounds” produced naturally by hookworms could help treat some metabolic disorders. But the new study takes things further – by engineering in an extra molecule for the worm to secrete.

Mitreva and her team used CRISPR gene-editing technology to insert into a hookworm egg genome “a gene coding for an antibody known to counteract” the pufferfish poison tetrodotoxin, a lethal, weaponisable neurotoxin with no known commercial antidote. They then infected hamsters with the modified parasites, and samples taken later showed the hamsters had antibodies to tetrodotoxin circulating in their blood.

“It was like the perfect moment,” Mitreva told R&D World. Now “we can start embarking on hookworms being a two-in-one platform” because we’ve shown they “can not only deliver a drug, but produce that drug and deliver it”.

‘Internal allies’ 

The goal now is to use this technology on humans. In the future, we “could see these worms engineered to produce a variety of other medications and excrete them inside the human body”, said LiveScience. They could potentially provide long-term treatments for chronic conditions such as inflammatory bowel disease, or even protective treatments for military personnel exposed to chemical or biological threats. Mitreva’s study was, in fact, funded by the US Department of Defense with a view to developing a treatment for tetrodotoxin poisoning.

This is an “exciting” approach that “paves the way for all sorts of injection-free biologic drug delivery”, said ZME Science. It’s “tantalising” to think that “engineered hookworms could one day” be our “internal allies, providing continuous therapeutic benefits while living safely within a human host”.

The upcoming release of the UK’s first weight-loss pill, Wegovy, has been described as “game-changing” by a leading pharmacy provider.

“We’ve already seen record demand ahead of the expected launch”, said James O’Loan, chief executive of Chemist4U. With the majority of people expressing interest in the new obesity treatment not being previous users of weight-loss injections, this indicated that the new pill “could widen access to millions of people across the country”.

How does it work?

Made by Danish pharmaceutical giant Novo Nordisk, the pill is an oral version of weight-loss medicine Wegovy, containing the same active ingredient, semaglutide.

Where GLP-1 injections “pass directly into the bloodstream, the pill has to first be absorbed through the stomach”. This is possible through “scientific innovation, creating a way of encapsulating semaglutide and shielding it from stomach acid”, said The Telegraph’s health and medical journalist David Cox.

As with injections, the Wegovy pill “mimics the effects of a gut hormone called GLP-1, released after eating, which regulates appetite and signals a feeling of fullness”.

The pill is taken daily, compared to the weekly injection, and comes in different doses which can be steadily increased each month.

How effective is it?

Early tests suggest it has a similar effect to injectable Wegovy. After 64 weeks, adults taking the pill lost an average of 14% to 17% of body weight, with about one in three people losing 20% or more.

Regulatory guidelines from the Medicines and Healthcare products Regulatory Agency state that only people classified as clinically obese, with a Body Mass Index (BMI) of more than 30, or those who are overweight (BMI of 27-30) with at least one weight-related health condition such as high blood pressure or type 2 diabetes, will be eligible to receive the drug.

How much will it cost?

To start with, it will be available in the UK only on prescription privately and not free on the NHS. While exact prices are yet to be set, Robert Bradshaw, a superintendent pharmacist at Oxford Online Pharmacy, told The Telegraph he expects the Wegovy pill to “come in roughly at the same price as the injections”.

“I suspect the pill will be priced somewhere around about £80 to start with, progressing to £130 [for the intermediate dose], and maybe £160 for the top dose.”

With other drug companies developing their own weight-loss pills, however, “competition could also drive down the costs of treatment, as first-generation drugs, or those that offer slightly poorer top-line results, command lower prices”, said The Economist. Some government-funded health systems are likely to make “population-scale deals in the coming years, which could broaden access” further.

Are there any side-effects?

“These are similar whatever the version and related to levels of the drugs in the blood rather than how they are administered,” said Dr Mark Porter in The Times. Common side effects include “nausea and vomiting (slightly more common with the pill version), diarrhoea and/or constipation and abdominal discomfort, but these generally settle once people get used to the medicine”.

The much rarer but more serious side-effects “such as gallbladder problems (stones), inflammation of the pancreas (pancreatitis) and visual problems (optic neuropathy) probably remain the same as with injectables”.

But with the latest NHS statistics suggesting 66% of all people over 16 in England are overweight, and with obesity rates “continuing to spiral”, doctors are “optimistic that the emergence of GLP-1 tablets can serve as a major boost to public health”, said The Telegraph.

And globally, if generic semaglutide were made available to everyone with obesity and diabetes, it could save between 2.1 million and 3.1 million lives a year, according to one model, said The Economist.

If you have ever felt like you couldn’t stop eating your favorite sweet treats and savory snacks, that’s by design. The tobacco industry had a heavy hand in the growth of ultraprocessed food in the U.S. And despite no longer being involved, its marketing tricks remain.

A new addiction

Big Tobacco employed its tactics in marketing cigarettes to also market ultraprocessed food, according to a series of papers published in the American Journal of Public Health (AJPH). In the 1980s, U.S. tobacco giants Philip Morris and R.J. Reynolds made a “major entrance into the food industry” when they had “strong cash flows yet experienced growing scrutiny regarding their tobacco products,” said one of the AJPH papers. Investing in food and beverages was an attempt to improve their corporate image, so the team acquired several major brands, including Del Monte Foods, General Foods, Kraft, Nabisco and 7UP.

Tobacco companies “spent decades amassing research on how to make cigarettes more pleasurable and addictive with chemical additives” and “deliberately applied this knowledge to food manufacturing,” according to “internal company records,” said NPR. Thus came the rise of added sugars and artificial flavorings in food and beverages. These additives are known to be “hyperpalatable,” activating the same part of the brain as cigarettes or other drugs.

Along with changing the composition of the products, aggressive marketing tactics became the norm. Big Tobacco “applied the same strategies to developing light and reduced food products with the express goal of retaining customers who might otherwise stop consuming some of their products,” said lead paper author Tera Fazzino, an associate professor of psychology at the University of Kansas, to NPR.

The companies “divested from the food system from 2000 to 2007,” said the papers. However, their impact has been long-lasting. Ultraprocessed foods “now account for 70% of packaged foods in the U.S. and 62% of the calories in children’s diets,” said Fast Company. These foods have been linked to a variety of health problems, including obesity, diabetes and cardiovascular disease.

“Children are really, really vulnerable to this kind of messaging,” said paper author Laura Schmidt, a professor at the University of California at San Francisco, to The Washington Post. “The goal is to hook the consumer at the youngest possible age because, as you grow up, they have instilled brand loyalty in you.”

Trying to quit

There have been growing calls for regulating the production and sale of ultraprocessed foods, notably as part of Health Secretary Robert F. Kennedy Jr.’s Make America Healthy Again agenda. Last summer, for example, federal agencies “began a joint effort to define ultraprocessed food,” said Bloomberg. This definition could be “used on product labels in an effort to nudge consumers to reach for healthier items.” The ultimate goal is to implement labeling on the front of packaging that indicates what foods are ultraprocessed. But creating such a definition is not so simple, as it could “inadvertently ensnare some healthier items like yogurt.”

While Kennedy may be pushing back against ultraprocessed food, the Trump administration has made “policy changes that could exacerbate the problem,” said The Guardian. The administration also “failed to direct policy changes that could help, like redirecting government corn subsidies toward whole fruits and vegetables.”

But better monitoring could lead to needed changes. Countries might “consider establishing a baseline of ultraprocessed or hyperpalatable food availability in their food environments to monitor food system health,” said the papers. There may also be a “global need to consider regulation of multiple addictive products disseminated by tobacco companies.”

With many in the Trump administration pushing an anti-vaccine agenda, declining measles vaccination rates have forced scientists to reinvigorate the hunt for a drug that could fight the virus. While the FDA has not approved any measles drugs yet, researchers seem hopeful that a breakthrough is on the horizon.

Why are researchers revamping the measles drug search?

For a long time, the quest to create a measles drug was essentially dormant, as the virus “had been kept at bay in the United States for more than two decades thanks to a remarkably effective vaccine,” said The New York Times. But in 2025, amid anti-vaccine sentiment from the White House, a “series of outbreaks popped up in unvaccinated communities across the country,” marking the worst year for measles in the U.S. since 1991.

The outbreak led to a “‘very crowded’ hunt for new measles therapeutics that could prevent or treat infections,” said the Times. Currently, if an unvaccinated individual contracts the measles, doctors can “offer ways to manage symptoms, which often include fever, fatigue, cough and a hallmark blotchy rash,” said Science News. But they “can’t fight off the virus itself.”

How far away is an approved measles drug?

There have been several breakthroughs from various scientific groups, and many feel that FDA approval of a measles drug is imminent. At least one antiviral drug, GHP-88310, was recently shown to “help treat measles, croup and other related viral diseases that cause contagious and life-threatening respiratory infections,” said The Independent. The drug is the “most promising inhibitor” of this virus family that causes measles “we have encountered in years of research,” Carolin Lieber, a senior postdoctoral fellow at Georgia State University’s Center for Translational Antiviral Research, said in a statement.

GHP-88310, which is taken orally, could “offer a much-needed option to treat measles in the midst of increasing endemic transmission in the U.S. and throughout the world due to vaccine hesitancy,” said Drug Discovery News. The drug could provide an alternative to the typical measles defense mechanism, ring vaccination, in which “direct and social contacts around an infected person are vaccinated.” But with “increasing vaccine hesitancy in some population groups, ring vaccination is no longer a viable option in some communities.”

The success of the drug doesn’t necessarily mean it will become ubiquitous as a measles treatment, partially due to people’s feelings about the disease. “One of the biggest misunderstandings about measles is that it’s ‘not that bad,’” Kathryn Hastie, a structural virologist at San Diego’s La Jolla Institute for Immunology, said to Science News. The virus instead can “cause a range of complications that can severely impact people’s lives, including pneumonia and blindness.”

Another company, Saravir, is developing its own measles antibody treatment. The medication could be a “potential multi-billion dollar market opportunity,” Dr. Ronald Moss, Saravir’s CEO, told the Times. Moss estimates there are 44 million people in the U.S. and EU who are “uniquely vulnerable to measles,” and if even a small portion of that group is exposed, it’s a “pretty big population that we would want to protect.” Still, the antibody treatment and other measles drugs could be cost-prohibitive. If the “drug makes it through trials,” said the Times, Saravir “expects the infusions to cost roughly $2,500.”

The Food and Drug Administration has approved the use of bemotrizinol (BEMT) in sunscreens. The chemical has been used in European and Asian brands of sunblock for decades. BEMT can provide better sun protection and last longer while being less greasy on the skin.

New kid in the block

Sunscreens are supposed to protect against both ultraviolet A (UVA) and B rays (UVB). UVB is “high-energy radiation that is typically associated with sunburns and can cause genetic mutations that lead to skin cancer,” said Scientific American. UVA rays have also “increasingly become recognized as relevant for skin health,” and their “longer-wavelength radiation” can “penetrate deeper into the skin than UVB, breaking down the skin’s structure and creating harmful, skin‑aging molecules.” Unfortunately, while most U.S. sunscreens are effective against UVB radiation, they “provided significantly lower UVA protection with the average unweighted UVA protection factor just 24% of the labeled SPF,” said a 2021 study.

BEMT, though, is capable of ”protecting against both ultraviolet A and B rays while not leaving white streaks associated with mineral-based sunscreens,” said The Associated Press. The ingredient is “generally recognized as safe and effective for use in sunscreens by adults and children 6 months of age and older,” said the FDA. “For too long, American consumers have been applying sunscreen and believing they were fully protected, not knowing that their product was delivering far less UVA protection than the label implied,” Alexa Friedman, a senior scientist at the Environmental Working Group, said in a statement.

Screening issues

There have been many efforts to get the government to approve new sunscreen ingredients, but they were “bogged down for decades by the FDA’s bureaucratic system for updating its lists of safe nonprescription drug ingredients,” said the AP. Bemotrizinol’s approval marks the “first ingredient to go through a streamlined process authorized by Congress in 2020.”

Sunscreen is an important step in preventing skin cancer, but there has been a mounting anti-sunscreen movement “amid an increasing distrust of the medical establishment and a desire by some for natural alternatives,” said The Washington Post. Much of the concern has surrounded chemical sunscreens, which get absorbed into the skin. In 2019, scientists from the FDA found that these sunscreens’ ingredients can stay in the body at unsafe levels after just one day of use. Bemotrizinol is “broad-spectrum and far more stable, so it doesn’t break down in the sun,” said NBC News. It “also has low levels of absorption into the body.”

What the US is trying to do in Kenya reeks of “neo-colonialism”, said The Daily Nation (Nairobi). To protect Americans from the deadly Ebola outbreak that is thought to have already killed at least 91 people in the Democratic Republic of Congo (DRC), the Trump administration has decreed that no one with the disease may enter its borders, even if they’re a US citizen. Any American unlucky enough to have contracted the virus in DRC should instead be sent for treatment hundreds of miles away to a specially commissioned Ebola health centre in Kenya.

Cue outrage in Nairobi. “Kenya is NOT America’s biohazard dumping ground,” fumed a spokesman for one of Kenya’s doctors’ unions, echoing widespread fury at the proposal to set up a 50-bed quarantine facility at Kenya’s Laikipia Air Base. And hundreds of protesters took to the streets of Nanyuki, the town closest to the air base, fearing the disease might spread to their community. They blocked roads and set fire to tyres, and police had to fire tear gas to disperse them.

According to some reports, two people were shot dead. Yet despite the uproar, and a temporary court order blocking the site’s construction, Kenya’s President William Ruto has vowed to press ahead with it.

Potentially ‘catastrophic’

The debacle in Kenya is far from the only mistake the US has made over the Ebola crisis, said The East African (Nairobi). “Epidemics are best fought collectively”, but under Trump the US has withdrawn from the World Health Organisation (WHO) and shut down USAID, scuppering the international response needed to stem the current outbreak, which has now spread to Uganda.

Trump’s decisions have been disastrous, said Craig Spencer in The New York Times. Over the past year, critical surveillance networks in DRC have been dismantled, with the result that US officials only learnt of the first Ebola death a month after it happened, making it inevitable that the outbreak would turn “catastrophic” in scale.

To put this in context, the world’s worst-ever Ebola outbreak, which broke out in Guinea in 2014, went on to kill 11,300 and infect 28,600 others. That outbreak was first detected when there were around 40 to 50 cases; for this one, that number was 400 to 500. And to make matters worse, rapid tests and vaccines do not exist for the Bundibugyo strain of Ebola that is behind this latest epidemic.

“We are not getting ahead of this virus. We are running after it,” said Denis Mukwege in Le Monde (Paris). It’s already the third-largest outbreak in history, and could well become the deadliest ever.

Deep mistrust

The challenges facing teams on the ground are immense. For a start, the epicentre of the outbreak is war-torn eastern DRC, where conditions make contact-tracing almost impossible. And as the US has cut aid to the DRC from $1.34 billion in 2024 to just $428 million in 2025, local responders have “far fewer resources” than in any comparable recent crisis.

To add to the crisis, front-line health workers are “deeply” mistrusted by the local population, said The Economist. Look what happened two weeks ago in the small town of Mongbwalu in northern DRC, where a group of young men made four different attacks on the local hospital in a bid to retrieve the body of an Ebola victim for burial. The day before that, townsfolk had torched an isolation unit.

The crucial requirement is for the response to be consolidated under a single actor, just as it was for the 2014 outbreak when the UN Mission for Ebola Emergency Response (UNMEER) took charge, said Anthony Banbury in The Washington Post. Congolese health workers and international NGOs have done an excellent job so far, but the lack of coordination has been a serious hindrance. “It is like going to war with scattered, independent military units, but no central headquarters directing the overall effort.”

In the absence of a body like UNMEER to devise and oversee a strategy for containing the outbreak, this epidemic could “spin out of control”. And then the world would be in real trouble.

The size of the global beauty and personal care market is astounding and is expected to approach $700 billion in 2026. From scented shampoos festooned with exotic oils to anti-aging creams and blemish-removers, those who can afford them seem to have a bottomless appetite for new products. Discerning consumers, however, may notice small but significant differences in ingredient lists depending on whether their purchases are made in the European Union or the United States.

These differences may look random but reflect longstanding differences in public health philosophies. “The EU tends to act on early signals, animal studies, preliminary lab findings, and the U.S. believes in waiting for real-world evidence before restricting anything,” said Ashley Fike at Vice. Still, the scope of the beauty market means that regulators need to stay vigilant even after bans are issued. Consumer Reports, for example, found methylene chloride in a number of hair dyes that the company tested in April 2026, despite the chemical being banned in the U.S. for cosmetics products since 1989.

Here are six prominent examples of beauty products and ingredients the EU has prohibited that remain legal in the U.S.

Coal Tar Dyes

Unlike many of the substances on this list, coal tar dyes are exactly what they sound like — or at least they were when they were invented. They are “mainly derived from petroleum nowadays, but they have retained their original name,” said Consumer Reports.

The FDA “must approve these color additives for use” in most beauty care products, although a loophole still exists for hair dyes, “which do not require FDA approval as long as the product includes a special cautionary statement and directions for a preliminary skin test,” said Consumer Reports. Hair dyes have been linked to increased risk of a number of different cancers, “including uterine and breast cancer, as well as the formation of ovarian tumors,” said the Environmental Working Group.

Formaldehyde and formaldehyde-releasing preservatives

Formaldehyde is a commonly used ingredient in nail polishes, hair straighteners and even some liquid baby soaps in the United States. In liquid baby soaps, consumers may find these formaldehyde releasers in ingredient lists: DMDM hydantoin, quaternium-15, diazolidinyl urea, imidazolidinyl urea, bronopol and sodium hydroxymethylglycinate.

Yet these ingredients are typically found only in trace amounts in baby soap products. “Maybe the greatest benefit of fearmongering about formaldehyde in shampoo is to make mommy breathless,” said Joe Schwarcz at McGill University. The chemicals, in the end, are found in higher concentrations in products like hair gels and dyes. Some states are running ahead of the federal government on this front, with Washington banning the use of formaldehyde-releasing chemicals in 2025.

Hydroquinone

Hydroquinone “works by decreasing the production and increasing the degradation of melanin pigments in the skin” and thereby “increasing the risk of skin cancer,” said the Campaign for Safe Cosmetics. In the U.S. it is mostly used in skin-lightening products purchased mostly by people of color, making its continued legality especially problematic.

The EU has banned all use of hydroquinone in cosmetics, while the U.S. has required a prescription to access such products since 2021. As with many other such ingredients, it is relatively easy to acquire them without a prescription if you know where to look. Regulators promised to “take action against those continuing to market these potentially harmful and illegal OTC products,” said the FDA.

Parabens

Parebens are “chemicals known for their preservative and antimicrobial properties” that “protect products from the things that shorten shelf life, such as yeast, bacteria and mold,” said the Cleveland Clinic. Just as the United States has more permissive rules governing these items’ use in food products, so too are parabens more likely to be found in beauty products in the U.S. versus the EU.

Parabens that are banned in the EU include isopropylparaben, isobutylparaben, phenylparaben, benzylparaben and pentylparaben, while others like propylparaben and butylparaben are allowed only under strict concentration limits. As for the U.S., we “do not have information showing that parabens as they are used in cosmetics have an effect on human health,” said the FDA.

Phthalates

Phthalates are “typically colorless liquids used to make plastics more flexible and resilient,” said the Centers for Disease Control. Some studies suggest that these chemicals can “disrupt hormones and damage the reproductive system,” said the Environmental Working Group.

The EU has banned the use of dibutyl phthalate (DBP) and diethylhexyl phthalate (DEHP) in cosmetics and personal care products. You can find phthalates in a number of products in the U.S., including nail polish removers and scented soaps. Critics charge that the U.S. has largely allowed the beauty and personal care industry to regulate itself. U.S. government regulators insist they don’t “have evidence that phthalates as used in cosmetics pose a safety risk,” said the FDA.

Triclosan

Triclosan is an “antimicrobial agent found in a wide variety of antibacterial soaps and detergents, as well as in many deodorants, toothpastes, cosmetics, fabrics and plastics,” said the Campaign For Safe Cosmetics. There is also evidence that it is an “endocrine disruptor and impacts thyroid function and thyroid homeostasis.”

The chemical remains an ingredient in countless products from whitening toothpastes to eyeshadows, although the FDA did ban its inclusion in household soap products in 2016. Companies can still include triclosan in over-the-counter antiseptic after going through a premarket review process with the FDA, and the chemical can be used without restriction in cosmetics and toothpastes. In the EU, triclosan is completely banned in cosmetics as of 2025, and products containing it “can no longer be made available on the European market,” said the Obelis Group.

For the people of Gaza, “fear is no longer linked only to what falls from the sky”, but also to “what crawls from below”, said Prospect.

Rats and other rodents have “taken over everything in a frenzy” and, with summer approaching, their numbers are expected to soar even higher.

Physical and psychological threats

A “plague” of rodents is “terrorising” the area, said the Financial Times, as rats and weasels “chew their way into tents, biting children and contaminating food”. A Unicef spokesperson who visited Gaza this month said rodents are becoming “a huge, huge problem because of accumulated rubble everywhere”.

The threat they pose is more than psychological. Rats transmit diseases through urine and waste, causing fever and other illnesses. Diabetic patients are particularly vulnerable to rodent bites, as they may not feel it happening and serious complications can occur.

More than 72,000 Palestinians have been killed in Israel’s war in Gaza, and rats began “eating human bodies under the rubble”, Samah al-Dabla, who was displaced from Beit Lahiya in northern Gaza, told Al Jazeera.

Rats are now appearing in the tents where many Gazans live. Al-Dabla has tried to buy rat poison but the prices are too high and she already struggles to afford enough food for her family. Any food she manages to obtain tends only to attract more rats.

Mounting problem

Dr Ayman Abu Rahma, director of preventive medicine at Gaza’s Ministry of Health, told Al Jazeera that the problem has three main causes: damage to sewage systems, decomposing bodies under the rubble, and the amount of rubbish building up in the territory. Gaza City’s main landfill site is a “breeding ground for rodents in a densely populated area”, said Al Jazeera.

Local officials want to convert waste into organic fertiliser, but the war has destroyed much of the equipment needed for such a process.

The urgency is clear: rubbish dumps are located close to tents in displacement sites, creating serious “health hazards that will increase as summer temperatures rise”, humanitarian officials and residents told the Financial Times.

Cogat, the Israeli Ministry of Defence body that monitors aid access to Gaza, said that “nearly 170 tons of pesticides and thousands of traps for rats, mosquitoes, and other pests have been brought into the Gaza Strip in recent weeks”.

But Salim Oweis, the Unicef spokesperson who visited Gaza, said the amount allowed in is “barely enough for a few weeks” and “the whole of Gaza” is affected.

A needle-free universal vaccine may soon be on the horizon. Scientists have successfully run the first trial, which showed the vaccine can safely elicit an immune response to several viruses. But more research is needed before it’s approved for widespread use, so larger trials are now planned.

How was the vaccine developed?

This universal vaccine is the first human-tested inoculation to have its active component designed by computer simulations, according to a study published in the Journal of Infection. The vaccine has an AI-created “super-antigen,” a “protein that mimics shared features across multiple coronaviruses, rather than targeting a single specific strain, which can trigger the body’s immune system to fight a broad array of pathogens with those base characteristics,” said Euronews. Researchers “used all the available genetic sequence data for Sarbeco coronaviruses,” which are “zoonotic viruses that primarily circulate in bats and can jump to humans or other mammals.” They then “applied machine learning to create the super-antigen.”

“Viruses like influenza, coronaviruses and the Ebola group are evolving continuously, and by the time vaccines are rolled out, they may be poorly matched,” Saul Faust, a professor at the University of Southampton and the study’s chief investigator, said in a news release. But this “new class of universal vaccines are future-proofed,” as they “not only protect against many variants simultaneously but potentially against related viruses that haven’t yet emerged.” The universal vaccine can therefore curb outbreaks and even prevent future pandemics.

The vaccine is also needle-free. It’s administered through a microfluidic jet, which “uses a high-pressure, hair-thin stream of liquid to push vaccine blueprints directly into skin cells,” said Sky News. Without needles, it has greater “global applicability by reducing volume requirements, eliminating sharps waste and improving uptake in settings where needle-based administration is a barrier,” said Euronews. And it also doesn’t have to be kept as cold as traditional vaccines, making it “well-suited for use in low- and middle-income countries and in rapid-response scenarios.”

Is it effective on humans?

The vaccine has already shown promise in humans. The first clinical trial was conducted with 39 volunteers, and it was “well-tolerated at all four doses with no significant safety concerns elicited,” said the study. It also “triggered immune responses in the volunteers not only to SARS-CoV-2 and SARS but to related bat viruses that could potentially jump from animals to humans and cause future pandemics,” said the release.

However, the “magnitude of the response was limited and did not increase predictably with higher doses,” though this is likely influenced by prior Covid-19 exposure and vaccination history among participants, said the study. A larger Phase 2 trial will “next assess the vaccine’s ability to induce immune responses in a wider and more diverse population and confirm that it generates strong, broadly protective immune responses,” said the release.

The clinical trial proves the success of a whole new way to create vaccines. The use of AI “could protect against future emerging virus threats” and reduce the “need for frequent reformulation, which is a fundamental limitation of current vaccines,” said the release.

The old vaccine development system was like a “dog chasing its tail,” study lead Jonathan Heeney, a researcher from the University of Cambridge’s Lab of Viral Zoonotics, said in the release. “We can escape the constant cycle of chasing the virus variants circulating in humans and updating the vaccines to try to catch up.”

‘Flu vaccines should not be this hard’

Katherine J. Wu at The Atlantic

In a “typical year, the process of bringing a new seasonal flu shot to market is one of the United States’ most predictable vaccine routines,” but this is “not a typical year,” says Katherine J. Wu. The job would normally “fall to the CDC’s expert vaccine advisory panel, known as ACIP, which guides the agency’s recommendations,” but “currently, no functional ACIP exists to guide this autumn’s immunization campaigns.” This “could further undermine ACIP’s role as a key scientific check on government policy.”

‘How women are shaping Minnesota’s cannabis industry’

Clemon Dabney at The Minnesota Star Tribune

Cannabis legalization “created a market in Minnesota. Women are helping create its culture,” says Clemon Dabney. While women are “still underrepresented in cannabis ownership,” the “women who are launching dispensaries across the state” are “doing far more than opening stores.” These women are “claiming space in an industry where they have too often been overlooked, underestimated or asked whether a man is really behind the business.” They “are setting the tone for what this market becomes.”

‘Is Britain getting a new prime minister?’

Eliot Wilson at The Hill

In “America, changes of leaders are predictable,” but “in Britain, it is more nuanced,” says Eliot Wilson. It is “impossible to predict whether Sir Keir Starmer will still be prime minister at the end of this year, this month or perhaps even this week.” There is “no bar to a party in office changing its leader, who then becomes prime minister.” Will the United Kingdom “have a new prime minister by autumn? Yes. Or possibly no.”

‘AI leaders are cosplaying James Bond villains’

Gautam Mukunda at Bloomberg

“Shark Tank impresario Kevin O’Leary wanted to build data centers on 40,000 acres in rural Box Elder County, Utah,” the “latest battle in the war that might determine the future of artificial intelligence,” says Gautum Mukunda. AI “might unleash miracles of productivity, cure cancer or make energy too cheap to meter,” but it “can’t do any of those things — or at least it can’t do them in the United States — if the public rejects the technology.”
