What’s next for IVF

What’s next for IVF

Forty-eight years ago this July, Louise Joy Brown became the world’s first person born with the help of in vitro fertilization. Millions more IVF babies have entered the world since then. And that’s partly thanks to advances in technology that have made IVF safer and more effective. But it’s still...

Digging for clues about the North Pole’s past

Digging for clues about the North Pole’s past

In the past, even with an icebreaker and during peak melt season, getting to the North Pole wasn’t a sure bet.

Il arrive à lire un LaserDisc avec un simple microscope

Shelby Jueden, un passionné de tech rétro qui anime la chaîne YouTube Tech Tangents, vient de montrer qu'un simple microscope numérique permet de distinguer le contenu vidéo gravé sur un LaserDisc. L'encodage analogique du format rend les données directement visibles sous grossissement, alors que...

Mechanistic interpretability: 10 Breakthrough Technologies 2026

Mechanistic interpretability: 10 Breakthrough Technologies 2026

Hundreds of millions of people now use chatbots every day. And yet the large language models that drive them are so complicated that nobody really understands what they are, how they work, or exactly what they can and can’t do—not even the people who build them. Weird, right? It’s also a problem....

Meet the new biologists treating LLMs like aliens

How large is a large language model? Think about it this way. In the center of San Francisco there’s a hill called Twin Peaks from which you can view nearly the entire city. Picture all of it—every block and intersection, every neighborhood and park, as far as you can see—covered in sheets of...

Listening to battery failure

Listening to battery failure

Lithium-ion batteries produce faint sounds as they charge, discharge, and degrade. But until now, nobody could interpret those sounds to detect when a battery might be about to lose power, fail, or burst into flames. Now, MIT engineers have found a way to do that, even with noisy data. The findings...

AI materials discovery now needs to move into the real world

The microwave-size instrument at Lila Sciences in Cambridge, Massachusetts, doesn’t look all that different from others that I’ve seen in state-of-the-art materials labs. Inside its vacuum chamber, the machine zaps a palette of different elements to create vaporized particles, which then fly...
