How 3D printing could make better cooling systems
A new 3D-printed design could make an integral part of cooling systems like air conditioners or refrigerators smaller and more efficient, according to new research. Heat exchangers are devices that whisk away heat, and they’re everywhere—used in data centers, ships, factories, and buildings. The aim is to pass as much heat as possible from one […]
The Download: brain-computer interfaces, and teaching an AI model to give therapy
This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Brain-computer interfaces face a critical test Brain computer interfaces (BCIs) are electrodes put in paralyzed people’s brains so they can use imagined movements to send commands from their neurons through a wire, or […]
How do you teach an AI model to give therapy?
On March 27, the results of the first clinical trial for a generative AI therapy bot were published, and they showed that people in the trial who had depression or anxiety or were at risk for eating disorders benefited from chatting with the bot. I was surprised by those results, which you can read about […]
Brain-computer interfaces face a critical test
Tech companies are always trying out new ways for people to interact with computers—consider efforts like Google Glass, the Apple Watch, and Amazon’s Alexa. You’ve probably used at least one. But the most radical option has been tried by fewer than 100 people on Earth—those who have lived for months or years with implanted brain-computer […]

The first trial of generative AI therapy shows it might help with depression
The first clinical trial of a therapy bot that uses generative AI suggests it was as effective as human therapy for participants with depression, anxiety, or risk for developing eating disorders. Even so, it doesn’t give a go-ahead to the dozens of companies hyping such technologies while operating in a regulatory gray area. A team […]
How a bankruptcy judge can stop a genetic privacy disaster
Stop me if you’ve heard this one before: A tech company accumulates a ton of user data, hoping to figure out a business model later. That business model never arrives, the company goes under, and the data is in the wind. The latest version of that story emerged on March 24, when the onetime genetic […]

“Spare” living human bodies might provide us with organs for transplantation
This week, MIT Technology Review published a piece on bodyoids—living bodies that cannot think or feel pain. In the piece, a trio of scientists argue that advances in biotechnology will soon allow us to create “spare” human bodies that could be used for research, or to provide organs for donation. If you find your skin […]
Anthropic can now track the bizarre inner workings of a large language model
The AI firm Anthropic has developed a way to peer inside a large language model and watch what it does as it comes up with a response, revealing key new insights into how the technology works. The takeaway: LLMs are even stranger than we thought. The Anthropic team was surprised by some of the counterintuitive […]
