AI titan Anthropic has launched a biology ‘wet lab’ where human scientists and AI agents will work together to design and conduct experiments. The company has released one of the team’s first finds: a peculiar pattern of DNA in the genomes of several giant viruses. go.nature.com/3Tq5g4D

Anthropic’s AI biolab finds ‘CRISPR-like’ DNA in viruses. What’s next?
The detection effort enlisted roughly 950 AI agents that spent more than 21 hours combing through DNA sequence databases.

I’m jealous of everyone who got to be there! I met Dr. Moreau at the Evolution conference, and her SSB presidential talk was inspiring. Definitely don’t miss her talk if you get the chance!

Museums aren’t just collections — they’re classrooms. 🦋🏛️ @corriemoreau.bsky.social's #Scopes100 talk shows how exhibits make #evolution accessible & engaging. loom.ly/vFnwcRo @ncse.bsky.social
Promotional graphic for Corrie Moreau’s Scopes Symposium lecture titled Teaching Evolution through Museum Exhibits. On the left, Moreau is shown speaking at a podium, wearing glasses and a patterned jacket, gesturing with her hands. On the right, text reads “Corrie Moreau – Teaching Evolution through Museum Exhibits.” Logos for Vanderbilt Evolutionary Studies and the National Center for Science Education appear at the bottom, along with a small photo of framed butterfly specimens in a museum display.
