Inventor recalls eye imaging breakthrough

If you’ve been to an eye doctor and had an image taken of the inside of your eye, chances are good it was done with optical coherence tomography (OCT)—a technology invented by clinician-scientist David Huang ’85, SM ’89, PhD ’93, and now used in 40 million procedures per year.  OCT is a...

AI at MIT

AI at MIT

At MIT, AI has become so pervasive that you can almost find your way into it without meaning to. Take Sili Deng, an associate professor of mechanical engineering. Deng says she still doesn’t know whether she’d have gone all in on artificial intelligence had it not been for the covid pandemic....

This tool could show how consciousness works

This tool could show how consciousness works

How does the physical matter in our brains translate into thoughts, sensations, and emotions? It’s hard to explore that question without neurosurgery. But in a recent paper, MIT philosopher Matthias Michel, Lincoln Lab researcher Daniel Freeman, and colleagues outline a strategy for doing so with...

Artificial scientists

Artificial scientists

AI companies frequently invoke the possibility of AI-enabled scientific discovery as a justification for their existence: If the technology eventually cures cancer and solves climate change, then all the carbon emissions and slop videos will have been well worth it.  Already, LLMs can assist...

China’s open-source bet

Silicon Valley AI companies follow a familiar playbook: Keep the secret sauce behind an API, and charge for every drop. China’s leading AI labs are playing a different game: They ship models as downloadable “open-weight” packages. This lets developers adapt the models and run them on their own...

Weaponized deepfakes

Weaponized deepfakes

For years, experts have warned that deepfakes—AI-generated videos, images, or audio recordings of people doing or saying things they haven’t actually done in real life—could be deployed in malicious ways.  These dangers are now here. Improvements in deepfake technology, and the widespread...

Building agent-first governance and security

Building agent-first governance and security

As AI agents increasingly work alongside humans across organizations, companies could be inadvertently opening a new attack surface. Insecure agents can be manipulated to access sensitive systems and proprietary data, increasing enterprise risk. In some modern enterprises, non-human identities...

Git 2.54 introduit en expérimentation la commande git history

Git 2.54 introduit en expérimentation la commande git history

Git annonce la version 2.54. La principale fonctionnalitée est la commande git history. Attention, pour le moment, elle est en expérimentation. git history est là pour "réécrire" l'histoire des référentiels Git. On peut déjà réorganiser un dépôt avec la fameuse commande rebase. Pour des cas plus...

Colossal Biosciences said it cloned red wolves. Is it for real?

Colossal Biosciences said it cloned red wolves. Is it for real?

If you want to capture something wolflike, it’s best to embark before dawn. So on a morning this January, with the eastern horizon still pink-hued, I drove with two young scientists into a blanket of fog. Forty miles to the west, the industrial sprawl of Houston spawned a golden glow. Tanner...

Chinese tech workers are starting to train their AI doubles–and pushing back

Chinese tech workers are starting to train their AI doubles–and pushing back

Tech workers in China are being instructed by their bosses to train AI agents to replace them—and it’s prompting a wave of soul-searching among otherwise enthusiastic early adopters.  Earlier this month a GitHub project called Colleague Skill, which claimed workers could use it to “distill”...

The Download: bad news for inner Neanderthals, and AI warfare’s human illusion

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. The problem with thinking you’re part Neanderthal There’s a theory that many of us have an “inner Neanderthal.” The idea is that Homo sapiens and a...
