When a whale dies, it often decomposes quite quickly-the process starts within hours of an animal's stranding on shore. Depending on the species, they may have six inches or more of blubber, an insulating layer that traps heat inside and turns their internal organs to mush. That can make Jennifer Bloodgood's job very difficult. As...

Are you feeling it? I hear it's close: two years, five years-maybe next year! And I hear it's going to change everything: it will cure disease, save the planet, and usher in an age of abundance. It will solve our biggest problems in ways we cannot yet imagine. It will redefine what it means to...

Mustafa Suleyman, CEO of Microsoft AI, is trying to walk a fine line. On the one hand, he thinks that the industry is taking AI in a dangerous direction by building chatbots that present as human: He worries that people will be tricked into seeing life instead of lifelike behavior. In August, he published a...

A few weeks ago, I set out on what I thought would be a straightforward reporting journey. After years of momentum for AI-even if you didn't think it would be good for the world, you probably thought it was powerful enough to take seriously-hype for the technology had been slightly punctured. First there was the...

MIT researchers have developed a new bionic knee that is integrated directly with the user's muscle and bone tissue. It can help people with above-the-knee amputations walk faster, climb stairs, and avoid obstacles more easily than they could with a traditional prosthesis, which is attached to the residual limb by means of a socket and...

A lot of attention has been paid to how climate change can reduce biodiversity. Now MIT researchers have shown that the reverse is also true: Loss of biodiversity can jeopardize regrowth of tropical forests, one of Earth's most powerful tools for mitigating climate change. Combining data from thousands of previous studies and using new tools...

With help from artificial intelligence, MIT researchers have designed novel antibiotics that can combat two hard-to-treat bacteria: multi-drug-resistant Neisseria gonorrhoeae and Staphylococcus aureus (MRSA). The team used two approaches. First, they directed generative AI to design molecules based on a chemical fragment their model had predicted would show antimicrobial activity, and second, they let the...

City life is often described as fast-paced." A study coauthored by MIT scholars suggests that's more true than ever: The average walking speed in three northeastern US cities increased 15% from 1980 to 2010, while the number of people lingering in public spaces declined by 14%. The researchers used machine-learning tools to assess 1980s-era video...

Chatbots today are everything machines. If it can be put into words-relationship advice, work documents, code-AI will produce it, however imperfectly. But the one thing that almost no chatbot will ever do is stop talking to you. That might seem reasonable. Why should a tech company build a feature that reduces the time people spend...
