A team of U.S. and South Korean researchers have developed an AI model called MSI-SEER that can not only predict microsatellite instability-high (MSI-H) tumors based on tissue slides, but also flag “what it does not know.” “Have you ever asked ChatGPT anything, and the response was, ‘I don’t know?’” Cheong Jae-ho asked during an interview with BioWorld. “Probably not, and that is the problem with AI now.”

The Nobel Committee announced today that it has awarded the 2025 Nobel Prize in Physiology or Medicine to three scientists for their discovery of regulatory T cells, which are a critical part of the way the body prevents autoimmune attacks.

Pharma companies are collaborating to boost the power of artificial intelligence (AI) in drug discovery by allowing access to proprietary structural data to train a large language model. Each of the partners is contributing data from several thousand experimentally determined protein:ligand interactions, creating one of the most diverse datasets and the richest chemistry assembled to date for model training.

The Human Cell Atlas project has delivered a fresh tranche of data mapping fibroblasts in healthy and diseased skin and pointing to drug targets with potential in multiple diseases across a range of tissues. Using single cell sequencing and spatial genomics, a technique for showing how gene expression varies at different locations within a tissue, nine different subpopulations of fibroblasts were identified, six in healthy skin and three in disease samples.

Globally, over half of people living with HIV are women. But in clinical cure trials, they make up only about 20% of participants. And that gender imbalance is causing researchers to miss out on ways to improve cure strategies. Because women’s immune systems appear to be better at controlling HIV infection in a way that silences the reservoir – the provirus integrated into host cells in infected persons.

The Royal College of Psychiatrists in the U.K. has published its first-ever guidance to support research into psychedelic drugs as therapies for conditions including treatment-resistant depression, substance abuse disorders and posttraumatic stress disorder, saying that in a fast-moving field there is a risk of jumping ahead of the evidence.

Two back-to-back papers published in Nature on Sept. 10, 2025, shed new light on the unexpected role of neurons in shaping the evolution of small-cell lung cancer (SCLC). It’s already known that, in gliomas, cerebral cancer cells actively damage axons, contributing to tumor progression through direct neural disruption.
