Raj Chetty got his biggest break before his life began. His mother, Anbu, grew up in Tamil Nadu, a tropical state at the southern tip of the Indian subcontinent. Anbu showed the greatest academic potential of her five siblings, but her future was constrained by custom. Although Anbu’s father encouraged her scholarly inclinations, there were no colleges in the area, and sending his daughter away for an education would have been unseemly.

But as Anbu approached the end of high school, a minor miracle redirected her life. A local tycoon, himself the father of a bright daughter, decided to open a women’s college, housed in his elegant residence. Anbu was admitted to the inaugural class of 30 young women, learning English in the spacious courtyard under a thatched roof and traveling in the early mornings by bus to a nearby college to run chemistry experiments or dissect frogs’ hearts before the men arrived.

The 50th anniversary of the moon landing is almost here, and NASA has gone all-out for the occasion.

The agency has been celebrating the memory of Apollo 11 for months. It has published a steady stream of archival photos and footage of the astronauts suiting up, blasting off, and posing on the lunar surface with the American flag, a pop of color against an expanse of gray. It refurbished the room at the Johnson Space Center where Mission Control monitored the journey so that now it looks the way it did in 1969, down to the coffee cups, clipboards, and packs of cigarettes. NASA headquarters even asked every communications officer at the agency to be “mindful of posting evergreen materials during the next few weeks that could get better attention once we’re past that spotlight event,” a spokesperson told me. Apollo 11 is NASA’s most famous mission, and the moon landing is one of the most defining moments in human history. It’s been moon time, all the time.

Robert Spada walked into the decrepit warehouse in Detroit and surveyed the chaos: Thousands of cardboard boxes and large plastic bags were piled haphazardly throughout the cavernous space. The air inside was hot and musty. Spada, an assistant prosecutor, saw that some of the windows were open, others broken, exposing the room to the summer heat. Above the boxes, birds glided in slow, swooping circles.

It was August 17, 2009, and this brick fortress of a building housed evidence that had been collected by the Detroit Police Department. Spada’s visit had been prompted by a question: Why were police sometimes unable to locate crucial evidence? The answer lay in the disarray before him.

America needs teachers: A majority of the country’s most experienced K–12 educators are expected to retire in the next few years, while research suggests that thousands of others will likely leave the profession prematurely, citing job dissatisfaction. How to get more people to join the profession? A little more than a decade ago, policy makers came up with one idea they thought would help: Give teachers some extra support in paying off their student loans. So, in 2007, Congress tasked the U.S. Department of Education, which administers federal financial aid, with offering student-debt relief to recent graduates in public-service careers: Essentially, make your minimum monthly payments for 10 years and your loans will be erased.

It might have been the first-ever nationalist revolt launched from a Ritz-Carlton ballroom. This week, conservative intellectuals and politicos in Washington tucked into plated dinners and sipped from at least four varieties of seltzer at a new gathering, the National Conservatism Conference. In defiance of conservative-movement shibboleths, they applauded new rallying cries: No more worshipping on the altar of free markets at the expense of the middle class. No more endless wars dedicated to slaying perceived monsters overseas. No more shame about saluting the flag, defending borders, and demanding assimilation. “Today,” declared Yoram Hazony, the American-educated Israeli scholar who organized the event, “is our independence day.”

In the summer of 2017, the mountain lions, bobcats, and other residents of the Santa Cruz Mountains were treated to the dulcet tones of the ecologist Justin Suraci and his friends, reading poetry. Some of the animals became jittery. Others stopped eating. A few fled in fear.

Suraci, who’s based at the University of California at Santa Cruz, wasn’t there to see their reactions. He and his colleagues had strung up a set of speakers that would regularly play recordings of human speech in an area where people seldom venture. And they found that, the quality of the poetry aside, even the gentlest of human speech can make wild animals—even top predators—unnerved and watchful, in ways that shake entire food webs. It’s the clearest demonstration yet that we are among the scariest of animals—a super-predator that terrifies even the carnivores that themselves incite terror.

Magali Trejo-Martinez, a 22-year-old living in Salem, Oregon, recently went on a date that was rather uninspiring. “I had dinner, had a couple margaritas, and then went home,” is how she recapped the evening. This outcome wasn’t entirely surprising—she says she wasn’t very interested in the guy when she agreed to go out with him—but it wasn’t a letdown either, because he paid the bill. While her heart wasn’t in it, her stomach was: “I mean, if it’s dinner, I’m not going to say no, so that I don’t have to go home and cook,” she told me.

Trejo says that when she goes on a date where food, not romance, is her priority, she doesn’t feel bad, noting that she still makes an effort to be an engaging dinner companion. “If it’s a guy that’s inviting me out, I do expect them to be the one to pay,” she says. “But I am also bi, so if I like a girl, I like to be the dominant one and then I will go and pay.” And when she is the one who gets asked, she’ll sometimes still say yes to an otherwise inauspicious date. “If it involves food,” she said, “I am always down.”

Heaps of research suggest that social relationships make people happier—but which relationships, specifically? A guilt-ridden afternoon with a mother-in-law might not have the same effect as drinks with a best friend. A “fair-weather friend” stands by your side only during good times.

Recently a group of researchers set out to determine whose company we actually seek out when we’re happy or unhappy. Their findings, published this month in the journal Psychological Science, suggest that when times are actually good, the people we turn to aren’t friends at all. They’re strangers.

The study’s authors looked at the moods and social interactions of more than 30,000 people, most of whom were French, over the course of a month. The data were collected through an app called 58 Seconds, which would text the participants at various times of the day and ask them to type in how they were feeling, what they were doing, and whom they were with, if anyone.

Some conservative national-security practitioners gathered recently to find common ground on the future. The meeting wasn’t, as described in The Washington Post, flooded with regretful signatories of various anti-Trump letters, recanting in the hopes of career advancement. In attendance were people who had served in the Trump administration and people who’d refused to serve, united by a desire to restore principled national-security policies. What follows is an abbreviated version of my paper for the gathering, which was on how to engage young Americans with conservative principles.

In my experience, conservative foundational beliefs appeal to our successors. We can win over young Americans to our principles, but first we have to live by those principles. Americans under age 30 voted for Democrats by a 35-point margin in 2018 in large part because we don’t.

The American conventional wisdom about weight loss is simple: A calorie deficit is all that’s required to drop excess pounds, and moderating future calorie consumption is all that’s required to maintain it. To the idea’s adherents, the infinite complexity of human biology acts as one big nutritional piggy bank. Anyone who gains too much weight or loses weight and gains it back has simply failed to balance the caloric checkbook, which can be corrected by forswearing fatty food or carbs.

Endocrinologists have known for decades that the science of weight is far more complicated than calorie deficits and energy expenditures. And in 2016, the fickle complexity of weight came to broad national attention. In a study of former contestants on a season of the weight-loss reality show The Biggest Loser, scientists found that years later, the contestants not only had gained back much or all of the weight they’d lost on the show, but also had far weaker metabolisms than most people their size. The contestants’ bodies had fought for years to regain the weight, contrary to the contestants’ efforts and wishes. No one was sure why.
