Does every scientist need an AI co-scientist? We sat down with @jrpenades & @CostaT_Lab, two @imperialcollege professors putting @google's new 'AI co-scientist' tool to the test. How long did it take AI to solve the mystery they'd spent a decade trying to figure out? 🧵

AI can accelerate scientific discovery, but only if we get the scientist–AI interaction right. The dream of ā€œautonomous AI scientistsā€ is tempting: machines that generate hypotheses, run experiments, and write papers. But science isn’t just an automation problem — it’s also a

The best thing AI has done for bio is make bio an essential/critical part of the growth story for the biggest companies in the world. In the medium/long term, this will bring in amounts of capital into bio that we have never seen before. Big Tech / MAG7 has always had moonshot

Genome maintenance by telomerase is a fundamental process in nearly all eukaryotes. But where does it come from? Today, we report the discovery of telomerase homologs in a family of antiviral RTs, revealing an unexpected evolutionary origin in bacteria. https://t.co/OlU6HOLQfK
