Astronauts are more than cosmic travelers. They’re also research subjects in the careful study of what exactly outer space does to the human body. On the ground, researchers measure vitals, draw blood, swab cheeks, and more. In orbit around the Earth, the astronauts do the work themselves.

That’s how they found the blood clot.

An astronaut was carrying out an ultrasound on their own body as part of a new study, guided in real time by a specialist on the ground. A similar test before the astronaut launched to space had come back normal. But now the scan showed a clump of blood.

“We were not expecting this,” says Karina Marshall-Goebel, a senior scientist at NASA and the author of the study, published earlier this month. “This has never been reported before.”

His eyes fall to the floor when I ask him to describe it. We’ve been tiptoeing toward it for 45 minutes, and so far, every time he seems close, he backs away, or leads us in a new direction. There are competing theories in the press, but Joe Biden has kept mum on the subject. I want to hear him explain it. I ask him to walk me through the night he appeared to lose control of his words onstage.

“I—um—I don’t remember,” Biden says. His voice has that familiar shake, the creak and the croak. “I’d have to see it. I-I-I don’t remember.”

We’re in Biden’s mostly vacant Washington, D.C., campaign office on an overcast Tuesday at the end of the summer. Since entering the Democratic presidential-primary race in April, Biden has largely avoided in-depth interviews. When I first reached out, in late June, his press person was polite but noncommittal: Was an interview really necessary for the story?

Through four long days of impeachment hearings, witness after witness sat passively by as Republican lawmakers responded to their detailed testimony by arguing that President Donald Trump had a legitimate reason to be suspicious of Ukraine, because he believed that the country “tried to take me down” in 2016.

That silence from the witness table ended this morning, as Fiona Hill used her opening statement before the House Intelligence Committee to accuse Republicans on the panel of peddling a “false narrative” that amounted to Russian propaganda.

“Based on questions and statements I have heard, some of you on this committee appear to believe that Russia and its security services did not conduct a campaign against our country—and that perhaps, somehow, for some reason, Ukraine did,” Hill, the former top expert for Ukraine and Russia on the National Security Council, told the lawmakers. “This is a fictional narrative that has been perpetrated and propagated by the Russian security services themselves.”

For a reporter, it’s a heart-stopping moment. You’re in an interview and suddenly a source offers up something you never expected anyone to unearth: video evidence of the president’s perverse pleasures.

“You were going to ask about the pee tape?” Glenn Simpson, the co-founder of the research firm Fusion GPS, which commissioned the infamous Steele dossier, asks me. “We’re going to screen it for you right now.” He motions to a TV on the wall of his conference room. I turn to look, taken in by Simpson’s deadpan expression and convinced for a half second that he and his partner, Peter Fritsch, somehow possess the alleged clandestine video of Russian prostitutes urinating on a bed at the Ritz-Carlton Hotel in Moscow for the delectation of future President Donald Trump.

Devin Nunes, the ranking Republican on the Intelligence Committee, opened today with a statement attacking media reporting on the Trump administration. He singled out six stories for attack.

One of them was retracted by its publisher, CNN—a form of corporate responsibility never seen from a White House notorious for emitting six false statements in a single morning. Another was an opinion piece in New York magazine by Jonathan Chait that did not claim to report news, but instead built known facts into a damning narrative of Donald Trump’s Russia connection. The other four range from the exaggerated to the unverified to the apparently mistaken.

But let’s take a closer look at those errors and what they mean. One of the stories singled out by Nunes was published by BuzzFeed News. That story asserted that Trump had explicitly directed his then–personal attorney, Michael Cohen, to lie to Congress about the Trump Tower Moscow project. Cohen would ultimately testify to Congress that Trump’s direction was implicit, not explicit.

The flight that put the Boeing Company on course for disaster lifted off a few hours after sunrise. It was good flying weather—temperatures in the mid-40s with a slight breeze out of the southeast—but oddly, no one knew where the 737 jetliner was headed. The crew had prepared three flight plans: one to Denver. One to Dallas. And one to Chicago.

In the plane’s trailing vortices was greater Seattle, where the company’s famed engineering culture had taken root; where the bulk of its 40,000-plus engineers lived and worked; indeed, where the jet itself had been assembled. But it was May 2001. And Boeing’s leaders, CEO Phil Condit and President Harry Stonecipher, had decided it was time to put some distance between themselves and the people actually making the company’s planes. How much distance? This flight—a PR stunt to end the two-month contest for Boeing’s new headquarters—would reveal the answer. Once the plane was airborne, Boeing announced it would be landing at Chicago’s Midway International Airport.

To watch the public impeachment hearings of Donald Trump is to experience a very particular form of whiplash. The House inquiry has featured a series of small collisions, between Democrats and Republicans, yes, but also between accountability and its opposite. Here is a proceeding partly led by lawmakers who have, when it comes to the president, repeatedly prioritized fealty over facts. And here is the key question at hand—did Donald Trump extort a U.S. ally for his own political gain?—chafing against all the other questionable matters not being addressed in the hearing: the reported frauds, the well-documented lies, the atmospheric fact of Trump’s bigotries. The procedural precision guiding the House inquiry—bribery, high crimes and misdemeanors—is constitutionally mandated; it is a proportional response. Watching it play out, however, is a little like watching Hannibal Lecter getting tried for tax evasion.

Jessica Black is a Pittsburg, California, mother of two black teenagers, both of whom have been disciplined multiple times at their middle and high schools. Her daughter has been suspended more than once, and teachers often deem her son’s behavior out of line, reprimanding him for not taking off his hoodie in class and for raising his voice.

In observing her own family and others, Black has noticed a pattern: Behaviors that many black parents might consider annoying but developmentally appropriate, such as an ill-timed joke or talking back to an adult, are treated by school staff as cause for suspension. From there, students are pushed out of classrooms, lose learning time, and can end up in the school-to-prison pipeline. “It’s a totally different environment, a totally different culture,” Black said when we spoke in July 2018.

Listening to the radio on her drive home from work back in January, 48-year-old Brooke Clagett caught the tail end of an interview with a man she couldn’t identify. “I was just stunned by how, on every subject that he discussed, he sounded reasonable and thoughtful,” Clagett told me last night. She pulled up in front of her house, but she didn’t go inside: “It was one of those classic driveway moments where you stay in the car to get to the end of the interview to find out who the hell it was.”

The man turned out to be Pete Buttigieg, the 37-year-old mayor of South Bend, Indiana. Fans I’ve spoken with have sometimes talked about their first time hearing Buttigieg in the same way someone might describe a religious experience. But Buttigieg’s success in the presidential primary has, in some ways, been miraculous: A little-known Midwest mayor who decided less than a year ago to run for president is now leading polls in the first two voting states. And yesterday, Clagett, who first heard his voice 10 months ago, was the happy host of a crowded pro-Buttigieg debate-watch party at Hank’s Oyster Bar in the Dupont Circle neighborhood of Washington, D.C.

1. The Disappearance

At 12:42 a.m. on the quiet, moonlit night of March 8, 2014, a Boeing 777-200ER operated by Malaysia Airlines took off from Kuala Lumpur and turned toward Beijing, climbing to its assigned cruising altitude of 35,000 feet. The designator for Malaysia Airlines is MH. The flight number was 370. Fariq Hamid, the first officer, was flying the airplane. He was 27 years old. This was a training flight for him, the last one; he would soon be fully certified. His trainer was the pilot in command, a man named Zaharie Ahmad Shah, who at 53 was one of the most senior captains at Malaysia Airlines. In Malaysian style, he was known by his first name, Zaharie. He was married and had three adult children. He lived in a gated development. He owned two houses. In his first house he had installed an elaborate Microsoft flight simulator.
