Today my @nytimes.com colleagues and I are launching a new series called Lost Science. We interview US scientists who can no longer discover something new about our world, thanks to this year‘s cuts. Here is my first interview with a scientist who studied bees and fires. Gift link: nyti.ms/3IWXbiE

Now published! Our paper on:
(1) Accurate sequencing of sperm at scale
(2) Positive selection of spermatogenesis driver mutations across the exome
(3) Offspring disease risks from male reproductive aging

Sperm sequencing reveals extensive positive selection in the male germline - Nature

A combination of whole-genome NanoSeq with deep whole-exome and targeted NanoSeq is used to accurately characterize mutation rates and genes under positive selection in sperm cells.

Biology is much more complicated than most non-biologists can imagine. And AI is not going to change this anytime soon.

We still can’t predict much of anything in biology

Biology is hard. Yes, even for AI.

Very saddened to hear of John Gurdon’s passing. I’ve been lucky enough to interact with him at multiple points through my career - from undergrad lectures, through his position as former Chair of @biologists.bsky.social’s Board of Directors, and as an author at @dev-journal.bsky.social.

So excited and grateful to receive R24 NOA from NIH ORIP to create an integrated #zebrafish omics, histology and microCT 3D atlas!

Looking forward to an exciting work with Dr. Postlethwait of U of Oregon, who is the co-PI of the grant.
