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.

Earlier this week, Alexandria Ocasio-Cortez posted a tweet: At congressional events, she shared (the representative-elect of New York’s 14th Congressional District is currently in Washington for a series of orientations on the workings of the House), she keeps being mistaken for an intern. Or sometimes for the spouse of the person who must be the true new member of Congress. Ocasio-Cortez, a young woman who is also a woman of color who is also a democratic socialist—a politician who won her election, earlier this month, with 78 percent of her district’s vote—keeps getting told that she doesn’t quite belong in Congress. Her tweet sharing that experience was punctuated by a face-palm emoji. It went viral.

The writer Stewart Brand once wrote that “science is the only news.” While news headlines are dominated by politics, the economy, and gossip, it’s science and technology that underpin much of the advance of human welfare and the long-term progress of our civilization. This is reflected in an extraordinary growth in public investment in science. Today, there are more scientists, more funding for science, and more scientific papers published than ever before:

On the surface, this is encouraging. But for all this increase in effort, are we getting a proportional increase in our scientific understanding?  Or are we investing vastly more merely to sustain (or even see a decline in) the rate of scientific progress?

Research shows that practically every dimension of life happiness is influenced by the quality of one’s marriage, while divorce is the second most stressful life event one can ever experience.

Yet nearly half of all married couples are likely to divorce, and many couples report feeling unhappy in their relationships. Instructors of Northwestern University’s Marriage 101 class want to change that. The goal of their course is to help students have more fulfilling love relationships during their lives. In Marriage 101 popular books such as Mating in Captivity and For Better: The Science of a Good Marriage are interspersed with meaty academic studies. Students attend one lecture a week and then meet in smaller breakout groups to discuss the weekly topics, which range from infidelity to addiction, childrearing to sexuality in long-term relationships.

Vicky Warren feels like she’s been attacked from all sides lately. Across the street from her rental apartment in the working-class Los Angeles County city of Hawthorne, noisy planes take off and land at all hours, diverted to the local municipal airport from wealthier Santa Monica, where neighbor complaints have restricted air traffic. On the other side of her apartment, cars on the 105 Freeway sound the frustration of L.A. traffic. She’s even getting assailed within her walls: Termites have invaded so completely that she can’t keep any food uncovered. Flea bites cover her legs; rats are aggressively attacking the boxes she has stored in her garage.

So Warren was disappointed, but not surprised, to learn that invaders are coming from underground, too. She lives on 120th Street, where 40 feet underground Elon Musk’s Boring Company is building a 14-foot-wide, mile-long tunnel to pilot a futuristic transit system untested anywhere in the world. When it’s finished in December, the tunnel will start at the nearby headquarters of SpaceX, Musk’s aerospace company, and end a few blocks past Warren’s apartment. “We’re just sandwiched in between so much already,” Warren told me, shaking her head.

Before the WikiLeaks founder Julian Assange was an international fugitive, he was running a little-noticed experiment in radical transparency. In the early 2000s, his then-obscure site WikiLeaks was mainly concerned with posting small batches of previously private documents ranging from Swiss bank documents to Sarah Palin’s emails.

Then, in 2010, WikiLeaks posted a graphic video depicting the killing of perhaps a dozen Iraqis, including two Reuters journalists, at the hands of the U.S. military. The video brought the organization acclaim from civil libertarians and transparency advocates, and infamy within the U.S. military and elsewhere. Soon after its release, WikiLeaks posted its largest-ever cache of leaked material: a set of diplomatic cables and Army documents, many of which concerned the conduct of the wars in Iraq and Afghanistan. If WikiLeaks began as a mere internet curiosity when it was founded in 2006, within four years, national-security officials in the United States were publicly depicting it as a threat.

The change can be baffling to many parents: Their young girls are masters of the universe, full of gutsy fire. But as puberty sets in, their confidence nose-dives, and those same daughters can transform into unrecognizably timid, cautious, risk-averse versions of their former self.

Over the course of writing our latest book, we spoke with hundreds of tween and teen girls who detailed a striking number of things they don’t feel confident about: “making new friends,” “the way I dress,” “speaking in a group.” In our research, we worked with Ypulse, a polling firm that focuses on tweens and teens, to survey more than 1,300 girls from the ages of 8 to 18 and their parents. (The sample was broadly representative of the country’s teen population in terms of race and geographic distribution.) The data is more dramatic than we’d imagined: The girls surveyed were asked to rate their confidence on a scale of 0 to 10, and from the ages of 8 to 14, the average of girls’ responses fell from approximately 8.5 to 6—a drop-off of 30 percent.

The little girl in the photograph squints and smiles broadly in the sunlight. According to a now-deleted public post on Second Chance Adoptions’ Facebook page, the girl, who the agency calls “Reese” to protect her privacy, is 10 years old, and she has been a member of her family since she was born—first in foster care, then legally adopted just before her first birthday. She loves to laugh, her adopted mom says, and she smiles all the time. She loves pink. She has no special needs. But she needs a new home.

In other posts with more pictures, the reader learns that Reese is the youngest of four daughters; the other three are the biological children of her parents. She gets straight A’s. She loves her parents and her sisters. She grumbles only when her siblings ask her to clean her room. She rarely lies and loves to wear skirts and dresses and listen to music. But according to the information provided by her parents, “This family has drastically changed their lifestyle and have left their faith and extended family for a quiet, secluded life.” It is their hope that “a different family will step forward who can provide her with the socialization and continued relationship with God that she desires.” After spending her whole life thus far with her family, Reese was being advertised on Facebook and the internet at large as available for re-adoption.

Late one chilly evening last September, I excused myself from a small group huddled around a campfire to peck at and mumble into my phone.

No way was a camping trip going to make me miss my Italian lesson.

For most of the preceding year, I had religiously attended to my 15-minute-or-so daily encounters with the language-learning app Duolingo. I used it on trains, while walking across town, during previews at the movie theater. I was planning a trip to Rome in the late spring, and I’ve always been of the mind that to properly visit a country, you’ve got to give the language a shot.

But I had another reason for sticking with it: Duolingo is addictive. It pulled me right in, helping me set daily goals and then launching into simple phrases. Sometimes it demanded that I speak an Italian phrase or sentence (which I always did correctly, to hear Duolingo tell it). But more often it asked me to translate Italian phrases and sentences into English, or vice versa, providing multiple-choice responses. No tedious grammar or vocabulary drills—that stuff, apparently, would seep into my consciousness via exposure to increasingly varied, complex, and interesting sentences.
