At Wednesday's CNN/Univision debate, Hillary Clinton acknowledged something her critics have been saying for a while. "I am not a natural politician, in case you haven't noticed, like my husband or President Obama," she said, "so I have a view that I just have to do the best I can, get the results I can, make a difference in people's lives, and hope people see that I am fighting for them."

Seven swimmers, three rowers, and five canoeists have joined the growing list of Russian athletes banned from the upcoming Rio Games because of doping allegations. Among those banned are 2012 Olympic canoeing champion Alexander Dyachenko, canoeist and Olympic bronze medalist Alexey Korovashkov, and swimmer and Olympic bronze medalist Yulia Efimova.

The decisions were announced by the three sports' respective governing bodies Monday, following the International Olympic Committee's decision Sunday not to issue a blanket ban on Russian athletes over the state-sponsored doping scandal. Instead, each sport's federation has been tasked with investigating its athletes to determine who was implicated in the World Anti-Doping Agency's investigation, which revealed Russian officials tampered with urine samples at the 2014 Sochi Olympics.

The latest announcements bring the total number of Russian athletes banned since the IOC's announcement Sunday up to 18, BBC reported, and investigations are ongoing. The Rio Games begin Aug. 5. Becca Stanek

French President François Hollande said Tuesday that the attackers of a Normandy church had claimed allegiance to the Islamic State.

Two armed men stormed the church in the city of Rouen and took several hostages early Tuesday morning, including the priest and two nuns, then slit the priest's throat before being killed by police, according to The Associated Press. Jeva Lange

Four billion years ago, sometime around Earth's 560 millionth birthday, Luca was born.

Luca is your great-to-an-infinite-degree grandmother and grandfather, as it is your dog's and your goldfish's and your ficus'. Every living thing on Earth owes it existence to Luca, whose very name stands for "Last Universal Common Ancestor." It is the origin of life on Earth, from which the rest of us evolved. And now scientists believe they have mapped a genetic picture of the qualities that would have belonged to Luca, giving us a startling look at how life on Earth might have begun:

...By comparing their sequence of DNA letters, genes can be arranged in evolutionary family trees, a property that enabled [Dr. William F.] Martin and his colleagues to assign the six million genes to a much smaller number of gene families. Of these, only 355 met their criteria for having probably originated in Luca, the joint ancestor of bacteria and archaea.

Genes are adapted to an organism's environment. So Dr. Martin hoped that by pinpointing the genes likely to have been present in Luca, he would also get a glimpse of where and how Luca lived. "I was flabbergasted at the result, I couldn't believe it," he said.

The 355 genes pointed quite precisely to an organism that lived in the conditions found in deep sea vents, the gassy, metal-laden, intensely hot plumes caused by seawater interacting with magma erupting through the ocean floor. [The New York Times]

Chemist John Sutherland, of the University of Cambridge, has a rival theory that life formed in shallow pools, not the ocean. Others say that Dr. Martin's version of Luca is actually the sophisticated descendent of some other original Luca.

But regardless of which theory you believe, as James O. McInerney wrote in a commentary about Dr. Martin's research, Luca is "a very intriguing insight into life four billion years ago." Read all about it at The New York Times. Jeva Lange

A priest was killed after being taken hostage by two armed men in northern France on Tuesday morning, police say. The attackers stormed a church during mass in the Normandy city of Rouen and took several hostages, including the priest and two nuns, then slit the priest's throat before being killed by police, according to The Associated Press. One other hostage is in critical condition, the BBC reports.

The attack comes not even two weeks after an attacker killed 84 people in Nice with a truck, for which the Islamic State claimed responsibility. France is still on high alert following the Nice attack, and last year's terrorist attack in Paris that left 130 people dead. Police say a motive for the Rouen hostage-takers isn't apparent, but anti-terrorism teams have been called to investigate.

The first day of the Democratic National Convention on Monday had its ups and downs, Stephen Colbert said in his live post-convention Late Show monologue. "Bernie Sanders heartily endorsed Hillary Clinton," he said. "It was an impassioned speech, but disappointed some of his supporters. I have not seen that many crying women since Bernie opened for the Beatles." But Day 1 of the Democratic convention was "also known as Hillary Clinton and the terrible, horrible, no-good, very bad day," Colbert said, mostly due to Friday's leak of 19,000 hacked Democratic National Committee emails, showing the DNC favoring Clinton over Sanders.

"In an unprecedented show of bias, the Democrats threw their weight behind the registered Democrat," Colbert said. "That's not farr. That's like Sam's Club refusing to take your Blockbuster card." But if the day started out rocky on Monday, "by early evening, things had calmed down," he said. "But then Bernie supporter Sarah Silverman and Hillary supporter Al Franken took the stage, and Sarah got a little tired of the crowd," telling the "Bernie or Bust" crowd they are being "ridiculous." "Wow, it is rare when the comedian heckles the audience," Colbert said.

"There were a lot of great speeches tonight, but leave it to Michelle Obama to truly unify the Democrats," Colbert said. "With tonight's moving speech, she convinced everyone in that arena that it was finally time to elect as president of the United States former first lady Michelle Obama. She crushed it." Colbert ended with a joke so obvious he would be negligent in not making it: "Anyway, Michelle's speech was so good, I want to hear it again. When is Melania doing it?" Watch below. Peter Weber

As the Democrats kicked off their own chaotic national convention on Monday, Samantha Bee took a last, profanity-tinged look at last week's Republican National Convention. The theme of the GOP convention was that the world is scary and Hillary Clinton's Democrats are trying to divide the nation, a leitmotif Bee found both puzzling and ironic. "It takes a lot of balls to call your opponents divisive when your party is tearing itself in half because you nominated a sociopathic 70-year-old toddler," she said on Monday's Full Frontal.

If you watched last week's Republican convention, you might remember that Donald Trump was merely the last person on stage to portray a dark, broken, dystopian America — but it sounds much scarier when Rudy Giuliani, Florida Gov. Rick Scott, and other speakers are talking terror over the dramatic strains of "Dies Irae" from Mozart's Requiem. Forget "Morning in America," Bee said. "It's the middle of the night in America and someone's kicking in your door — oh, and also, Hillary took your guns away."

After playing some of Trump's speech, Bee said, "Oh, my god, is Donald Trump running for Batman?" But then she reconsidered, arguing that he's re-running Richard Nixon's 1968 campaign. "Now I'm pissed that people are picking on Melania — at least she plagiarized someone good," Bee said. "Like Trump, Nixon courted old, white middle Americans made anxious by civil unrest," a group Nixon called the "silent majority." But Trump won't be just like Nixon, she added. "Nixon got 15 percent of the black vote." There is some mildly NSFW language, but if that doesn't bother you, watch the rest of Bee's Trump-Nixon comparison below. Peter Weber

At the beginning of Monday's post-Democratic convention Late Show, Stephen Colbert took a bite of a Philly cheesecake he pretended to have found on the street of Philadelphia, and then things got strange. Colbert, dressed in hippy-faux tribal-rainbow pants attire, popped up behind what appeared to be the cast of a Hair revival to sing a raga-trance song called "Death, Taxes, and Hillary." A sample: "It's a cheesesteak jamboree, where your mind can be set free / And this power girl will change the world, if her donors all agree." The costumes mix late '60s and early 1970s counterculture and disco, the music is highly reminiscent of the Beatles' Maharishi period, and the animation is Yellow Submarine mixed with your most psychedelic screen saver. Watch below, and even if you're completely sober, you might feel a bit trippy by the end. Peter Weber
