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? š§µ

AI can accelerate scientific discovery, but only if we get the scientistāAI interaction right. The dream of āautonomous AI scientistsā is tempting: machines that generate hypotheses, run experiments, and write papers. But science isnāt just an automation problem ā itās also a

Agree - if bio is the (only) way AI companies can avoid being hated by public⦠Then yay! Finally money into bio?
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

Stand back everyone I have an AI take AI will accelerate biotech more if it can reduce the paperwork-and-meetings burden on scientists by 25% than if it can 100x the speed of data analysis

AI isnāt just a U.S. story anymore. The next wave could come from emerging marketsāwhere AI lowers the cost of talent, software, and distribution. Winners: $MELI $SE $NU $TSM $TCS.NS $INFY $HCLTECH.NS Losers: fragile grids, high-burn tech, and labor-only outsourcers. Read:

Whaa itās gonna be okay / encouraged to tweet links again?? š (And sounds like it was never intended to be discouraged..? What else in life is a lie..)

Wait. Wait. I sense a change in the biosafety filter... (2 weeks ago I couldn't get it to answer basic wikipedia knowledge about genes, now it's happily designing a high throughput screen)
Occasionally flipping back to Claude to see if there's anything it's better at and...so far, no (not even considering that it just refuses to answer bio questions of any sort)

Waaaa phages are responsible for telomerases too? What canāt they do?
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

Just read the paper, and first of all, it's a good paper! They actually went and did pre-training all the way to downstream post-training. The models are small but compared to trillion token LLMs, single cell data is just not that big. Retaining model arch was smart. BUT...here's
An exciting milestone for AI in science: Our C2S-Scale 27B foundation model, built with @Yale and based on Gemma, generated a novel hypothesis about cancer cellular behavior, which scientists experimentally validated in living cells.Ā With more preclinical and clinical tests,
