If “I told you so” had a sensation, it would be the sweet cocoon of an 80-degree workspace. For years, women have been saying that the AC is on too damn high. We’ve dragged not one but two sweaters to the office in the summer: one for our slowly numbing legs, and one for our shivering shoulders. Scientific studies have already shown that offices are set for men’s frostier preferred temperatures.

Now a new paper confirms what many of us have long suspected. Women don’t just prefer warmer office temperatures. They perform better in them, too.

For the study, published today in the journal PLOS One, the researchers Tom Chang and Agne Kajackaite had 543 college students in Berlin take different types of tests in a room set to various temperatures between 61 and 91 degrees Fahrenheit. First, the participants had to answer logic problems, like the one about a bat costing $1 more than a ball. Then, the students were asked to add up two-digit numbers without a calculator. Finally, they had to form German words out of the letter scramble ADEHINRSTU.

Do you remember the little woven finger traps you sometimes got as a kid, as a party favor or a reward at a fair? You could comfortably stick your fingers in, but if you tried to pull them out, the weave would tighten and you’d be stuck. Only by maneuvering gently, and not pulling too hard, could you extract yourself.

President Donald Trump finds himself in a sort of impeachment finger trap right now. He isn’t certain to be impeached—but every step he’s taking to try to squirm out of it seems to tighten the bind he’s in.

Consider the president’s tantrum on Wednesday. After inviting Speaker Nancy Pelosi and Senate Minority Leader Chuck Schumer to the White House for a meeting on infrastructure, Trump stomped out of the meeting, supposedly because Pelosi had earlier accused him of participating in a cover-up. (The accusation is unrebuttably true.) Trump insists he did not throw a fit—“I was purposely very polite and calm, much as I was minutes later with the press in the Rose Garden. Can be easily proven.”—but one can’t calmly blow off a meeting. It defeats the point.

T

he call came in 2014, shortly after Easter. Four years earlier, Catrin Almako’s family had applied for special visas to the United States. Catrin’s husband, Evan, had cut hair for the U.S. military during the early years of its occupation of Iraq. Now a staffer from the International Organization for Migration was on the phone. “Are you ready?” he asked. The family had been assigned a departure date just a few weeks away.  

“I was so confused,” Catrin told me recently. During the years they had waited for their visas, Catrin and Evan had debated whether they actually wanted to leave Iraq. Both of them had grown up in Karamles, a small town in the historic heart of Iraqi Christianity, the Nineveh Plain. Evan owned a barbershop near a church. Catrin loved her kitchen, where she spent her days making pastries filled with nuts and dates. Their families lived there: her five siblings and aging parents, his two brothers.

Back in February 2018, I sat down with two leaders of the House Freedom Caucus to discuss, among other things, whether fiscal conservatism had gone extinct.

A few days earlier, with encouragement from his budget director, Mick Mulvaney, President Donald Trump had signed a budget deal boosting federal spending by nearly $300 billion. I told the leaders, Mark Meadows and Jim Jordan, that it seemed precisely the kind of deal that Mulvaney, a self-professed fiscal hawk and a founding member of the Freedom Caucus, would have railed against during his time in Congress.

Meadows shrugged. “He wouldn’t have been supportive of it,” the North Carolina congressman told me. But “he’s got a different boss now.”

Barack Obama is literally more popular than Jesus among Democrats. Unfortunately, neither the former president nor any of the party’s 23 candidates currently seeking the 2020 nomination know quite what to do with that information.

Of course, before any serious endorsement conversation can commence, Obama has to finish his book (between rounds of golf and raising millions for his foundation). The writing has been going more slowly than he’d expected, and according to several people who have spoken with him, the 44th president is feeling competitive with his wife, whose own book, Becoming, was the biggest release of 2018 and is on track to be the best-selling memoir in history. Speaking on the condition of anonymity, like others in this story, these sources note he’ll occasionally point out in conversation that he’s writing this book himself, while Michelle used a ghostwriter. He’s also trying to balance the historical and political needs of a project that will be up to his standards as a writer, and not 1,000 pages long. Obama’s research process has been intense and convoluted, and it’s still very much ongoing, from the legal pads he had shipped to Marlon Brando’s old island in French Polynesia, where he spent a month in March 2017, to the interviews that aides have been conducting with former members of his administration to jog and build out memories.

Four years ago, I wrote a letter to John Walker Lindh, then–inmate number 45426-083 in the Terre Haute penitentiary, to ask for advice about jihadism, Islamic law, and the Islamic State. Lindh is the most famous jihadist America has ever produced. In December 2001, he was pulled, half-dead, from a cellar full of fellow al-Qaeda fighters in northern Afghanistan, and 10 months later he was sentenced to 20 years in U.S. prison for terror-related crimes. He is scheduled to be freed today, with three years off for good behavior, and many—including Donald Trump—have objected to his release.

The story of our correspondence is in my book The Way of the Strangers: Encounters With the Islamic State, but some details appear here for the first time.

I’m an economist. I love data and evidence. I love them so much that I write books about data-based parenting. When questions arise about how to support parents at work (for example, from Alexandria Ocasio-Cortez on Twitter), my first impulse is to endorse paid parental leave. Mountains of data and evidence show that paid leave is good for children’s health, and for mothers in particular. I am more than comfortable making a data-based case for this policy.

But experience, rather than pure data, leads me to believe that what happens after paid leave is nearly as crucial—that is to say, what happens when Mom and Dad return to the office. We need to normalize the experience of parenting while working.    

SEOUL, South Korea—“If the United States believes that it doesn’t need an alliance with the Republic of Korea, I would say it’s okay. If the United States doesn’t want the alliance, we don’t have to beg for it.”

It was a stunning statement to hear in Seoul from one of South Korea’s highest-ranking officials, considering it was in regard to a nearly 70-year partnership forged by American and Korean soldiers who fought and died together during the Korean War. And it was a sign that well beyond South Korea, the United States’ system of alliances is buckling under pressure from President Donald Trump’s campaign to renegotiate the terms of America’s involvement with the world—to turn what used to be a basic tenet of U.S. grand strategy into a blunt question of financial grand totals. Seated in his ornate chambers in April, the speaker of the National Assembly, Moon Hee-sang, was answering my question about Trump’s demand for South Korea to shell out more money to keep American troops in the country, and his threats to impose tariffs on South Korean goods.

Although coral reefs are home to bustling communities of gaudy marine life, half the fishes that live there are hardly ever seen. Aptly known as cryptobenthics—literally “hidden bottom-dwellers”—these species are mostly shorter than two inches and usually hidden in crevices. If you snorkel past, they’ll scurry away. But Simon Brandl of Simon Fraser University has made a career of studying them. And he and his team have now shown that cryptobenthics are a crucial component of healthy reefs because they, more so than other fish, are extremely good at dying.

Pretty much every predator on the reef eats cryptobenthics, and a full 70 percent of these tiny morsels are devoured every week. But since they also reproduce, hatch, and grow at equally phenomenal rates, new individuals are constantly replenishing the ones that are consumed. Entire generations can turn over in a matter of weeks. And this extreme life cycle, Brandl found, is the secret engine of the world’s coral reefs, fueling the food webs that allow their inhabitants to flourish in otherwise nutrient-poor waters.

Enter the phrase weekday wedding into a Google search, and the always revealing “People also ask” feature will serve up an especially telling pair of questions. A hefty portion of people who Google for more information on getting married during the workweek seem to be wondering two things: Do people have weekday weddings? And is it okay to have one?

Apparently, more American couples than ever have decided the answers are yes and yes (or, at the very least, yes and “Well, we think so”). According to data from the 2018 Real Weddings study, conducted by the wedding-planning website The Knot, approximately one in five weddings has taken place on a Monday through Friday for the past seven years. Kristen Maxwell Cooper, the editor in chief of The Knot, believes weekday weddings—the whole-enchilada kinds of weddings, with a ceremony, dinner, and reception, but held on a weekday—are much more popular now than they were a decade or so ago. And despite what many assume, that’s not just because they’re cheaper (though frequently they are); American weddings are transforming to reflect the individual tastes of brides and grooms, and when they take place is just one variable that engaged couples today feel empowered to customize.
