Am increasingly excited about agent use cases that can improve biology research. This feels like one of them!

Agents are finally starting to work in biology. We’ve partnered with Anthropic and major biotech vendors - Vizgen, AtlasXOmics, Takara, 10x Genomics - to build a tool that allows scientists to steer their own analysis with natural language. Raw spatial data to publication

Can you rejuvenate an old brain by giving it young immune cells? 🧠 My lab @calico put it to the test. In our new study, we replaced the brain's immune cells in old mice with young ones. The result? The old brain environment forced the young cells to age RAPIDLY. A 🧵👇

Nice to see epigenetic drift hitting mainstream. I recall how in 2008 we showed genes like HOX drift as a result of DNA repair and proposed this as a cause of aging — and almost no one knew what we were talking about https://t.co/Sv6ZK47pap
