Scientists are growing miniature human brains in labs around the world. (Yep, you read that right.) For Wired, Claire L. Evans reports on the latest research in the field of organoid intelligence, or OI, where scientists are artificially growing brain organoids from tiny human samples, whether skin, blood, teeth, or even hair. As these seed-sized globs mature, they are able to send and receive electrical signals, and even learn to remember and anticipate them. In other words, this living matter is programmable. “And this is where things get truly weird,” writes Evans.

For now, these neural computers are mostly of interest to researchers who want to work with neurons without taking on the tedious wet-lab husbandry themselves. Eventually, however, the company hopes that neurons will prove themselves to be an energy-efficient, resilient substrate for more general computing applications—including some tasks currently handled by AI, like image recognition and classification.

“When you think about what you want from AI, it’s biology,” said Brett Kagan, Cortical Labs’ chief operating officer, when I reached him over Zoom. “You want it to be self-repairing as much as possible. You want it to be adaptable. You want it to be long-lived. You want it to be energy-efficient. These are all features you get for free in biology.”

Every adult who purports to care about a free press should read at least one story about the frustrating hurdles and bad-faith nitpicking confronted by student journalists (and their advisors). Earlier this year, a young reporter for the Redwood High School Bark found a few local references in the US Department of Justice’s public files concerning Jeffrey Epstein, the sex offender who died in 2019 while awaiting trial on sex-trafficking charges. Soon, the high school faced legal threats, and administrators grew concerned that students had published inaccurate information. Ara Rosenthal tells the story of the steady, diligent young journalists who weathered the worries and pressures of the adults around them—and kept their story intact.

I have a vague eighth-grade memory of trying to run 400 meters in under a minute. The operative word here, of course, is “trying.” But what eluded me then is nothing for the middle- and high-school kids of today, who are shattering track records on a weekly basis. Some of that is sneaker technology, some of it is training, some of it seems to be an intense competitive drive fueled by social media. Whatever it is, Brendan I. Koerner has seen it in his own kids—and now he throws himself into the world of scholastic speedsters for his latest Wired feature.

The results make track old-timers shake their heads with wonder. In April, for example, an eighth-grade boy shattered the national middle-school record for the mile (he ran it sub-4:18). Just two weeks later, an eighth-grade girl ran the 400 meters faster than any US high schooler had at that point in the year (she clocked 51.58).

It’s not just the superstars who are getting faster. The runners in the pack behind them are picking up the pace, too, and they’re transforming what’s considered a decent time. “I think I have 10 middle-school girls who run between a 4:56 and a 5:16 mile,” says Peterson. “Ten years ago, you’d be like, ‘That’s insane.’ Now it’s nothing.” When these kids head to high school, they have the strength and experience to flourish right away. But given the sky-high expectations they face, the intensity can come at a cost.
