A woman’s uterus has been kept alive outside the body for the first time
“Think of this as a human body,” says Javier González. In front of me is essentially a metal box on wheels. Standing at around a meter in height, it reminds me of a stainless-steel counter in a restaurant kitchen. It is covered in flexible plastic tubing—which act as veins and arteries—connecting a

Why this battery company is pivoting to AI
Qichao Hu doesn’t mince words about how he sees the state of the battery industry. “Almost every Western battery company has either died or is going to die. It’s kind of the reality,” he says.

Are high gas prices good news for EVs? It’s complicated.
I live in a dense city with plentiful public transportation options and limited parking, so I don’t own a car. I’m often utterly clueless about the current price of gasoline. But as the conflict in Iran has escalated, fossil-fuel prices have been on a roller-coaster, and I’ve started paying attentio
The snow gods: How a couple of ski bums built the internet’s best weather app
The best snow-forecasting app for skiers and snowboarders isn’t from any of the federally funded weather services. Nor from any of the big-name brands. It’s an independent app startup that leverages government data, its own AI models, and decades of alpine-life experience to offer better snow (and s

Agentic commerce runs on truth and context
Imagine telling a digital agent, “Use my points and book a family trip to Italy. Keep it within budget, pick hotels we’ve liked before, and handle the details.” Instead of returning a list of links, the agent assembles an itinerary and executes the purchase. That shift, from assistance to execution,

This scientist rewarmed and studied pieces of his friend’s cryopreserved brain
L. Stephen Coles’s brain sits cushioned in a vat at a storage facility in Arizona. It has been held there at a temperature of around −146 degrees °C for over a decade, largely undisturbed. That is, apart from the time, a little over a year ago, when scientists slowly lifted the brain to take photos…

The Bay Area’s animal welfare movement wants to recruit AI
In early February, animal welfare advocates and AI researchers gathered in stocking feet at Mox, a scrappy, shoes-free coworking space in San Francisco.

Mind-altering substances are (still) falling short in clinical trials
This week I want to look at where we are with psychedelics, the mind-altering substances that have somehow made the leap from counterculture to major focus of clinical research. Compounds like psilocybin—which is found in magic mushrooms—are being explored for all sorts of health applications, inclu
