These should be boom times for sex.

The share of Americans who say sex between unmarried adults is “not wrong at all” is at an all-time high. New cases of HIV are at an all-time low. Most women can—at last—get birth control for free, and the morning-after pill without a prescription.

If hookups are your thing, Grindr and Tinder offer the prospect of casual sex within the hour. The phrase If something exists, there is porn of it used to be a clever internet meme; now it’s a truism. BDSM plays at the local multiplex—but why bother going? Sex is portrayed, often graphically and sometimes gorgeously, on prime-time cable. Sexting is, statistically speaking, normal.

In the early 1980s, the world of school book fairs was “a highly competitive and very secretive industry,” according to a New York Times article at the time. The fairs numbered in the thousands and spanned the United States. They were put on by a mix of organizers: A few national corporations, about 25 to 30 regional companies, and assorted bookstores.

By the 1990s, one organizer reigned: the Scholastic Corporation. Scholastic, founded in 1920 to publish books and magazines aimed at young readers, had purchased several of its smaller competitors. The company became the largest operator of children’s book fairs in the country, a title it still holds today.

But we’re not here to talk about Scholastic’s business history, and I think you know that. If you’re a young adult who attended elementary school in the United States, I’d guess that when you saw the headline on this story, something deep inside your mind cracked open. With an unmistakable pang of nostalgia, the memory of a Scholastic book fair, with all its concomitant joys, came flooding in.

“I want them to talk about racism every day,” Steve Bannon, President Donald Trump’s former strategist, told The American Prospect last year. “If the left is focused on race and identity, and we go with economic nationalism, we can crush the Democrats.”

Bannon was tapping into an old American tradition. As early as the 1680s, powerful white people were serving up racism to assuage the injuries of class, elevating the status of white indentured servants over that of enslaved black people. Some two centuries later, W. E. B. Du Bois observed that poor white people were compensated partly by a “public and psychological wage”—the “wages of whiteness,” as the historian David Roediger memorably put it. These wages pit people of different races against one another, averting a coalition based on shared economic interests.

I first felt reality shift when, at 7 a.m. on a Saturday, there was a line for a class called Body Blast Bootcamp, and I worried that there wouldn’t be enough room for everyone.

The draw to this explicitly not-fun undertaking, others in line told me, was that we would be glad to have done it when it was over. We all made it in, and the workout studio was a carpeted conference room where an Instagram-famous instructor with a microphone headset was waiting to give us high fives. “The hardest step is showing up!”

Once we started working out, a person walked around apparently taking Instagram videos, and people were not bothered by this. Another brought a mini tripod to get some shots of herself in action. There was shouting and a Coldplay house remix. Someone offered me a box of alkaline water, and I drank it because no neutral water was available.

Over the past few years, an international team of almost 200 psychologists has been trying to repeat a set of previously published experiments from its field, to see if it can get the same results. Despite its best efforts, the project, called Many Labs 2, has only succeeded in 14 out of 28 cases. Six years ago, that might have been shocking. Now it comes as expected (if still somewhat disturbing) news.

In recent years, it has become painfully clear that psychology is facing a “reproducibility crisis,” in which even famous, long-established phenomena—the stuff of textbooks and TED Talks—might not be real. There’s social priming, where subliminal exposures can influence our behavior. And ego depletion, the idea that we have a limited supply of willpower that can be exhausted. And the marshmallow test, where our ability to resist gratification in early childhood predicts our achievements in later life. And the facial-feedback hypothesis, which simply says that smiling makes us feel happier.

Last week, the NRA kept defending gun rights, the AARP kept advocating for older Americans, and the California Avocado Commission was as steadfast as ever in touting “nature’s highest achievement.” By contrast, the ACLU issued a public statement that constituted a stark, shortsighted betrayal of the organization’s historic mission: It vehemently opposed stronger due-process rights for the accused.

The matter began when Secretary of Education Betsy DeVos put forth new guidelines on how to comply with Title IX, the law that forbids colleges that receive federal funding to exclude any students, deny them benefits, or subject them to any discrimination on the basis of sex.

The most controversial changes concern what happens when a student stands accused of sexual misbehavior. “Under the new rules, schools would be required to hold live hearings and would no longer rely on a so-called single investigator model,” The New York Times reports. “Accusers and students accused of sexual assault must be allowed to cross-examine each other through an adviser or lawyer. The rules require that the live hearings be conducted by a neutral decision maker and conducted with a presumption of innocence. Both parties would have equal access to all the evidence that school investigators use to determine facts of the case, and a chance to appeal decisions.” What’s more, colleges will now have the option to choose a somewhat higher evidentiary standard, requiring “clear and convincing evidence” rather than “a preponderance of the evidence” in order to establish someone’s guilt.

In the east of Brazil, mysterious cones of earth rise from the dry, hard-baked soil. Each of these mounds is about 30 feet wide at its base, and stands six to 13 feet tall. From the ground, with about 60 feet of overgrown land separating each mound from its neighbors, it’s hard to tell how many there are. But their true extent becomes dramatically clear from space.

Using satellite images, Roy Funch from the State University of Feira de Santana has estimated that there are about 200 million of these mounds. They’re arrayed in an uncannily regular honeycomb-like pattern. Together, they cover an area roughly the size of Great Britain or Oregon, and they occupy as much space as the Great Pyramid of Giza 4,000 times over. And this colossal feat of engineering is, according to Funch, the work of the tiniest of engineers—a species of termite called Syntermes dirus, whose workers are barely half an inch long.

The Halifax Security Forum is designed to be a gathering of the world’s democratic countries, which are allied to protect each other. Hosted by the Canadian defense minister, the Forum’s signature is the brief videos that introduce the annual gathering. This year’s intro showed relay runners, mostly American, at the Olympics from Berlin in 1936 forward, ending in an uncertain baton handoff—a powerful metaphor for the free world’s worries about American leadership in the age of Trump.*

The Halifax Forum, occurring just after President Donald Trump unleashed yet another petulant tirade against Germany and France that culminated in the unseemly taunt that Parisians were speaking German until the U.S. intervened in World Wars I and II, had a funereal feel this year. Allies are grieving the loss of an America they believed in, as it sinks in that they cannot rely on us any longer.

QUEENS, N.Y.—“Choosing not to speak,” Alexandria Ocasio-Cortez was telling me one day last month, “is taken and read just as deliberately as choosing to speak.”

Fresh off her upset primary victory over Representative Joe Crowley here, the nation’s most famous congressional candidate was speaking pretty much everywhere this summer—stumping for fellow progressives all over the country, hitting the late-night talk shows, and jousting with her many conservative critics on Twitter.

Last week, Ocasio-Cortez made her Washington debut in similar fashion.

In town for the biannual weeklong orientation session for newly elected members of Congress, the 29-year-old progressive star from the Bronx narrated the experience in Instagram stories to her 642,000 followers, complained about being mistaken for a congressional spouse or intern on Twitter, and called out a conservative journalist who suggested she was dressed too fancily for “a girl who struggles.”

President Donald Trump says that the U.S. immigration system is broken, and in recent days he has railed against what he says is an “invasion” by Central American migrants making their way to the United States. Along with a regular diet of tweets to that effect, he has accelerated the process begun during the Obama presidency of deporting those in the country illegally; criticized the migration of family members of American citizens; and called for a merit-based system of immigration.

Trump’s support for a policy that attracts skilled workers might run counter to his administration’s actual actions, but it underscores a conundrum that has bedeviled successive presidential administrations: how to fix the country’s immigration system, with its years-long backlogs and millions of undocumented workers, while remaining competitive in a global marketplace.
