🧬GWAS is fundamental in drug discovery, linking disease to genetic variants. However, studying rare and uncommon diseases with GWAS is hard due to the huge sample sizes required. How can we use AI to help GWAS with small cohorts? In a multi-year collaboration GSK

Medicine thrives on knowledge, yet clinical vocabularies are fragmented. AI struggles to unify this knowledge, creating a gap in precision medicine. Excited to share unified clinical vocabulary embeddings, a project led by stellar Ruthie Johnson Half of healthcare foundation AI

This paper has been a long time coming: We looked at the genomes of historical bacterial samples over a century to look for trends of antibiotic resistance genes, finding multiple instances of them in infections before the age of antibiotics...

⚡️Really thrilled that #textgrad is published in @nature today!⚡️ We present a general method for genAI to self-improve via our new *calculus of text*. We show how this optimizes agents🤖, molecules🧬, code🖥️, treatments💊, non-differentiable systems🤯 + more!

🧬 Meet Lyra, a new paradigm for accessible, powerful modeling of biological sequences. Lyra is a lightweight SSM achieving SOTA performance across DNA, RNA, and protein tasks—yet up to 120,000x smaller than foundation models (ESM, Evo). Bonus: you can train it on your Mac. read

When his son Max was diagnosed with a rare disease, our colleague Thomas turned to Gemini to better understand complex scientific papers — and even make new connections across the research community. His story is a powerful reminder of why we work on AI. ↓

Had a great time presenting RLDIF yesterday GEMBio Workshop at #ICLR2025! As a bonus got some seed money from a pitch with Aviv Spinner on an exciting new project, more on that later 👀
