The fallout from the fact that data science/classical machine learning & generative AI are both called "AI" has been remarkably broad & persistent

Policy addresses the wrong harms, companies have been confused about who should lead efforts, hiring is misguided, academic discussion is often muddled.

We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...

After reading several pieces about the rise of China biotech, I think one of the narratives seems to be incorrect. The assumption that a faster regulatory path to first-in-human clinical trials compared to the west doesn't seem borne out by the data.

Nice list of thoughtful starting places for thinking about the implications of China's rising drug discovery capabilities.

Finally read this by @sashagusevposts.bsky.social - very interesting piece. There's some fascinating bit of sociology of science to be done on when things get counted as replication crises versus when they're seen as healthy methodological progress.

Super excited to announce our latest flagship model Borzoi: major props to Johannes & David Kelley et al for advancing it. It's been a long journey from our prior Enformer model into this one. A few innovations: i) longer DNA context, ii) adaptation to predict RNA-seq abundance and splice isoforms,
