Decoding the language of sleep with artificial intelligence Sleep is one of medicine's underused data streams. Clinically, disturbed sleep has often been treated as a symptom of a disorder, but sleep is also a physiological state in which brain, cardiac, respi...

The data from sleep is incredibly rich, a window into health and risk of many diseases, decoded by AI.

As speech models are being deployed in real-world taxi and emergency service settings, the failure to accurately transcribe named entities can cause delays and errors in critical settings.

What do LLMs think about on their own, when we let them think freely?

We generated 250K “daydream” samples across models 🧠
GPT → coding
Qwen → multiple-choice math exams
Llama → literature
DeepSeek → math, religion, psychology

This is figure 1, which shows LMs struggle to affirm first-person beliefs in factually false scenarios.

Large language models (LLMs) may not reliably acknowledge a user’s incorrect beliefs, according to a paper in Nature Machine Intelligence. The findings highlight the need for careful use of LLM outputs in high-stakes decisions. go.nature.com/48VRpIQ 🧪

AI bots wrote and reviewed all papers at this conference Event will assess how reviews by models compare with those written by humans.

Next week @jameszou.bsky.social & colleagues will host a conference where all the papers are written by AI agents & reviewed by them too.

What do you reckon? A good chance to put AIs through their paces? Or a way to divert AI slop from elsewhere? 🧪🤖

My story here:

A circular flow diagram that compares current and proposed practices for LLM development using data from adopters and non-adopters. Three gray boxes represent current practices: “R&D,” “Chat Models,” and “Adopters’ Needs and Usage Data,” connected in a clockwise loop with black arrows. A blue box labeled “Non-adopters’ Needs and Usage Data” adds a proposed feedback path, shown with blue arrows, linking non-adopter data back to R&D and adopters’ data.

As of June 2025, 66% of Americans have never used ChatGPT.

Our new position paper, Attention to Non-Adopters, explores why this matters: AI research is being shaped around adopters—leaving non-adopters’ needs, and key LLM research opportunities, behind.

"We found a troubling emergent behavior in LLM.
—When LLMs compete for social media likes, they start making things up.
—When they compete for votes, they turn inflammatory/populist.
—When optimized for audiences, LLMs inadvertently become misaligned."

Researchers create ‘virtual scientists’ to solve complex biological problems Stanford Medicine researchers created a team of virtual scientists backed by artificial intelligence to help solve problems in their real-world lab.

“Good science happens when we have deep, interdisciplinary collaborations, and often that’s one of the main bottlenecks and challenging parts of research,” said HAI Faculty Affiliate @jameszou.bsky.social who led a study on AI-driven virtual labs: med.stanford.edu/news/all-new...

Researchers create ‘virtual scientists’ to solve complex biological problems An AI lab developed by Stanford Medicine researchers has already shown promising results, generating ideas for a more effective COVID-19 vaccine in just a few days.

We created a team of AI agents to mirror my Stanford lab 🤖. Led by a PI agent, the AI scientists ran their own group meetings and discovered effective binders to new CoVID variants that we validated.
