Around 1,500 years ago, shortly after the collapse of the Roman Empire, a baobab tree started growing in what is now Namibia. The San people would eventually name the tree Homasi, and others would call it Grootboom, after the Afrikaans words for “big tree.” As new empires rose and fell, Homasi continued growing. As humans invented paper money, printing presses, cars, and computers, Homasi sprouted new twigs, branches, and even stems, becoming a five-trunked behemoth with a height of 32 meters and a girth to match.

And then, in 2004, it collapsed.

The tree’s demise was sudden and unexpected. In March, at the end of the rainy season, Homasi was in full bloom. But by late June, its health had suddenly deteriorated. One by one, its stems broke off from the gargantuan trunk and toppled. The last of them fell on New Year’s Day, 2005, ending 15 centuries of life.

The fires on the streets of Ferguson, Missouri, had barely stopped burning when the Department of Justice released an extraordinary report on the city’s police department. In the findings of the 2015 investigation of the Ferguson Police Department, the DOJ’s Civil Rights Division detailed how a municipality had built its social contract on a slow-rolling racist heist. Activists hoped that the Ferguson report—which was prompted by the 2014 police killing of an unarmed black teenager and found that police conduct had “severely damaged the relationship between African Americans and the Ferguson Police Department”—would not only change the city, but would signal that the United States was finally willing to confront the legacy of white supremacy. The Ferguson City Council reluctantly agreed to a consent decree with the DOJ that would overhaul city policing. Federal courts rejected voter-suppression schemes and reaffirmed affirmative action. Movements from Black Lives Matter to LGBTQ advocacy saw an opportunity to broaden the national civil-rights agenda.

Claire is a 14-year-old girl with short auburn hair and a broad smile. She lives outside Philadelphia with her mother and father, both professional scientists. Claire can come across as an introvert, but she quickly opens up, and what seemed like shyness reveals itself to be quiet self-assuredness. Like many kids her age, she is a bit overscheduled. During the course of the evening I spent with Claire and her mother, Heather—these aren’t their real names—theater, guitar, and track tryouts all came up. We also discussed the fact that, until recently, she wasn’t certain she was a girl.

Sixth grade had been difficult for her. She’d struggled to make friends and experienced both anxiety and depression. “I didn’t have any self-confidence at all,” she told me. “I thought there was something wrong with me.” Claire, who was 12 at the time, also felt uncomfortable in her body in a way she couldn’t quite describe. She acknowledged that part of it had to do with puberty, but she felt it was more than the usual preteen woes. “At first, I started eating less,” she said, “but that didn’t really help.”

Smartphones have by now been implicated in so many crummy outcomes—car fatalities, sleep disturbances, empathy loss, relationship problems, failure to notice a clown on a unicycle—that it almost seems easier to list the things they don’t mess up than the things they do. Our society may be reaching peak criticism of digital devices.

Even so, emerging research suggests that a key problem remains underappreciated. It involves kids’ development, but it’s probably not what you think. More than screen-obsessed young children, we should be concerned about tuned-out parents.

Yes, parents now have more face time with their children than did almost any parents in history. Despite a dramatic increase in the percentage of women in the workforce, mothers today astoundingly spend more time caring for their children than mothers did in the 1960s. But the engagement between parent and child is increasingly low-quality, even ersatz. Parents are constantly present in their children’s lives physically, but they are less emotionally attuned. To be clear, I’m not unsympathetic to parents in this predicament. My own adult children like to joke that they wouldn’t have survived infancy if I’d had a smartphone in my clutches 25 years ago.

It was immediately clear that change was afoot in Dallas. I’ve attended the annual gatherings of the Southern Baptist Convention dozens of times, but walking around the convention center this week, I was struck by how unfamiliar it all felt. When I was a child, the convention hall was a sea of silver combovers and smelled of denture paste. While the older, more traditionalist crowd was still present in Dallas, the younger, fresh-faced attendees now predominated.

“The generational shift happening in the SBC has thrust the group into the middle of an identity crisis,” says Barry Hankins, the chair of the department of history at Baylor University and co-author of Baptists in America: A History. “The younger generation thinks differently than the old-guard Christian right about culture and politics, and they are demanding change.”

At 6 o’clock in the morning, shortly after the sun spills over the horizon, the city of Kikwit doesn’t so much wake up as ignite. Loud music blares from car radios. Shops fly open along the main street. Dust-sprayed jeeps and motorcycles zoom eastward toward the town’s bustling markets or westward toward Kinshasa, the Democratic Republic of the Congo’s capital city. The air starts to heat up, its molecules vibrating with absorbed energy. So, too, the city.

By late morning, I am away from the bustle, on a quiet, exposed hilltop some five miles down a pothole-ridden road. As I walk, desiccated shrubs crunch underfoot and butterflies flit past. The only shade is cast by two lines of trees, which mark the edges of a site where more than 200 people are buried, their bodies piled into three mass graves, each about 15 feet wide and 70 feet long. Nearby, a large blue sign says in memory of the victims of the ebola epidemic in may 1995. The sign is partly obscured by overgrown grass, just as the memory itself has been occluded by time. The ordeal that Kikwit suffered has been crowded out by the continual eruption of deadly diseases elsewhere in the Congo, and around the globe.

It’s hard to think of something more tangible than a child incarcerated in a tent city or a former Walmart building—and yet as the story of families being separated at the border mushrooms, one of the central questions has been a semantic one: whether the migrant children are being kept in cages.

Here’s what no one disputes: When the children are separated from their parents, they’re sent to facilities where they are kept in chain-link pens they can’t leave. But are those cages? It depends on whom you ask.

For example, the Associated Press reported over the weekend: “Inside an old warehouse in South Texas, hundreds of children wait in a series of cages created by metal fencing. One cage had 20 children inside. Scattered about are bottles of water, bags of chips and large foil sheets intended to serve as blankets.”

1. The Aristocracy Is Dead …

For about a week every year in my childhood, I was a member of one of America’s fading aristocracies. Sometimes around Christmas, more often on the Fourth of July, my family would take up residence at one of my grandparents’ country clubs in Chicago, Palm Beach, or Asheville, North Carolina. The breakfast buffets were magnificent, and Grandfather was a jovial host, always ready with a familiar story, rarely missing an opportunity for gentle instruction on proper club etiquette. At the age of 11 or 12, I gathered from him, between his puffs of cigar smoke, that we owed our weeks of plenty to Great-Grandfather, Colonel Robert W. Stewart, a Rough Rider with Teddy Roosevelt who made his fortune as the chairman of Standard Oil of Indiana in the 1920s. I was also given to understand that, for reasons traceable to some ancient and incomprehensible dispute, the Rockefellers were the mortal enemies of our clan.

In recent years, the common wisdom has been that girls are dominating when it comes to academic achievement. In reading in particular, girls have consistently outperformed boys. Some studies have also found that in a typical U.S. school district, girls have all but caught up in math—a subject in which they had historically underperformed and from which they’d been discouraged thanks to persistent stereotypes about their academic interests. Take away the burden of challenging stereotypes and discriminatory beliefs and practices, the thinking goes, and girls will do just as well as boys in the STEM fields.

But now, a new study by a team of researchers led by the Stanford education professor Sean Reardon finds that girls’ dominance in school isn’t the case across demographics. Yes, the study confirms: Overall, in the average U.S. school district, girls and boys are performing about the same in math. But the study finds that in communities in which most families are affluent and white, and in which adult men far outearn women in income, girls continue to lag behind their male peers in math achievement. In some of these districts, boys on average outperformed girls in math by two-fifths of a grade level.

The desperate sobbing of 10 Central American children, separated from their parents one day last week by immigration authorities at the border, makes for excruciating listening. Many of them sound like they’re crying so hard, they can barely breathe. They scream “Mami” and “Papá” over and over again, as if those are the only words they know.
