At least 27 Palestinians are reported to have been killed and dozens injured in Israeli attacks on an aid distribution site in Rafah run by the Gaza Humanitarian Foundation – the third consecutive day of violence at the Israel and US-backed group's hubs.

UN Secretary-General António Guterres has called for an independent investigation into the shooting of Gazans seeking aid at GHF sites.

What is the GHF?
The group is the "linchpin" of a new system designed to "wrest distribution away" from UN aid organisations, said The Associated Press. There are currently four GHF hubs, "all close to Israeli military positions".

It remains unclear who is funding the group, which claims to have "more than $100 million in commitments from a European Union government", but has not named the country. The US and Israel have denied being the funding source.

Why is it controversial?
Aid distribution operations were handed to GHF after Israel demanded an alternative delivery plan, accusing Hamas of siphoning off a significant portion of the UN aid entering Gaza.

The UN has denied that allegation and rejects the use of GHF, arguing it allows Israel to use food as a weapon, violates humanitarian principles and is ineffective at delivering aid.

Is it ineffective?
Aid distribution points run by GHF have been chaotic. There was "no process" and "no system" in place to distribute food aid at the Rafah site, said Al Jazeera journalist Hind Khoudary, reporting from Gaza. "You just need to run first to be able to get the food" and only a "very limited amount" of "flour, oil, lentils and other canned food" is being distributed.

A "smart mother" often makes a "better diagnosis than a poor doctor": medical students are often given this century-old advice from pioneering German surgeon Dr August Bier.

That view has been backed by a new study that found parental intuition was better than medical tests at predicting the deterioration of an unwell child – strengthening the case for parents' concerns to be taken more seriously, and their right to ask for a second opinion.

'Permission to speak up'
The study, published in the Lancet Child & Adolescent Health, analysed data from nearly 190,000 A&E visits by children to a hospital in Melbourne, Australia. The carer of each child was asked, "Are you worried your child is getting worse?" The researchers found that "caregiver concern for clinical deterioration" was "significantly associated" with a need for ICU admission and mechanical ventilation, with children four times more likely to need such care if their caregiver had voiced these concerns.

Caregiver concern was "more strongly associated" with ICU admission than "any abnormal vital sign", including heart rate, breathing or blood pressure. Overall, children whose caregivers had said they were concerned the child was deteriorating were "more unwell, more likely to be admitted to an inpatient ward, and stayed in hospital almost three times as long".

These are findings "we cannot ignore", said lead study author Erin Mills, of Melbourne's Monash University. Parents should be treated "as part of the care team and "we want every hospital to recognise that, and give parents the permission, and power, to speak up".

A boost for Martha's Rule
The findings will boost support for Martha's Rule, the new scheme in NHS hospitals that gives patients and their families the right to an urgent second medical opinion about a seriously ill patient. It is named after Martha Mills, who died of sepsis in a London hospital after her parents "repeatedly raised concerns" about her deterioration but were "dismissed" by doctors, said The Times.

MPs heard in March that thousands of patients or their loved ones had already sought a second opinion about their NHS care under the trial.

BBC One's Bafta-winning "Race Across the World" has become one of the channel's hottest shows, spawning a celebrity spin-off and even a live immersive experience in London. The much-loved programme follows two-person teams racing to a finish line that is often in a far-flung  part of the world. This year, the five teams are covering 8,700 miles, from the Great Wall of China to the far south of India, in a bid to win £20,000.

The challenge lies in the wildly low budget that they must stick to for the two-month adventure – the cash equivalent of the air fare from start to finish. But plane journeys, as well as credit cards and mobile phones, are banned.

Some fans are so enamoured with the premise that rather than battle through the ultra-competitive audition process, they are embarking on their own adventures with limited budgets and resources. Some of the "DIY trips" taken by "adventurous families" include interrailing around Europe, a "hop-on, hop-off" bus trip through Peru and a four-month "epic journey" across South America, said The i Paper.

One of last year's winners, Alfie Watts, has shared his top tips. Watts, who travelled from Japan to Indonesia on the show, recommends budgeting for £40 a day as a minimum and considering less-trodden paths. "I was absolutely shocked by the affordability of Uzbekistan when I went there in March," he told eSIM travel company Airalo. "I also found Brazil and, of course, Southeast Asia extremely cheap."

Some travel agencies have also devised their own tours inspired by the show. Audley Travel offers various itineraries in China, Nepal and India, including a 15-day "Classic China tour" of "iconic sites".

Rachel Reeves must think big to fund Labour's 'battle-ready' Britain. Tweaks and tinkering won't do
Polly Toynbee in The Guardian
"Who in their right mind would want to be Rachel Reeves right now?" writes Polly Toynbee. At next week's spending review, "whatever the numbers say", the story will be of "painful cuts to most things". Revenue must be raised for defence but the "whole tax and spending ship is an unseaworthy rustbucket encrusted with barnacles" that needs "stripping down and rebuilding". Labour MPs should "grasp worthwhile reform": they have "nothing to lose but their nerve".

20 Months Into the Genocide, Zadie Smith and Ian McEwan Discover Their Backbones
Nadeine Asbali on Novara Media
After "600 days of genocide", some famous UK writers have "finally decided to speak up against Israel's brutal annihilation of Gaza", says Nadeine Asbali. Online reactions to their open letter applaud their "bravery", but "is it really brave" just to "speak out at the exact point it poses least threat to their careers"? We should remember "those who came before" these signatories and "risked their fortunes and platforms to speak up for Palestine".

Tinder now has a height feature. What a relief
Claire Cohen in The Times
Predictably, people are saying Tinder's new height feature is "a 'filter for short men', followed by the usual chorus of 'women are so shallow'". Yes, it can be "rotten for short men on dating apps, but it's often rubbish for tall women too". I'm 5ft 9in and recall my "disappointment" when a man I met after "months of chatting online" turned out to be 5ft 4in. All of us "reserve the right to fancy who we fancy".
