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.”

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One of them was retracted by its publisher, CNN—a form of corporate responsibility never seen from a White House notorious for emitting six false statements in a single morning.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.

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.

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.

In the fierce struggle over impeachment, Donald Trump and his Republican defenders are escalating their war on expertise.

As an array of career diplomatic and military officials offer damning testimony against Trump—a procession that will continue today with the appearance of former National Security Council adviser Fiona Hill—the GOP is reprising arguments from 20th-century conservative populists that portray experts as untrustworthy and contemptuous elites out to subvert the will of ordinary Americans. The challenge Trump faces is that such attacks may backfire among the growing number of Americans with advanced degrees, a population that is now much larger than when such conservative firebrands as Joseph McCarthy and George Wallace wielded similar arguments decades ago.
