New paper with @jacobmusser.bsky.social @dts.bsky.social on reproducibility of LLM assisted research. Much of what we learned about engineering reproducible work in past decades still applies. Central organizing principle is whether the LLM sits on data path or off it. www.cell.com/patterns/ful...

Sailing in @biorxivpreprint.bsky.social ready for summer, our study on the iconic Portuguese man o' war 🪼 is out: www.biorxiv.org/content/10.6.... We use (epi)genomics to understand a critter that fascinates me since childhood. Massive team effort with @obog.bsky.social, Cummins and Neely groups. 🧵

Ever wanted to assemble specific genes out of raw sequence reads? Try sharkmer, a tool for in silico PCR (sPCR) developed with @shchurch.bsky.social - academic.oup.com/bioinformati.... Feed it raw reads and primer sequences, it gives you amplicon sequences. Can work on a laptop in minutes.

Sharkmer: repurposing PCR primers for targeted genome assembly using in silico PCR

AbstractSummary. We introduce an in silico PCR (sPCR) method for the assembly of specific genomic regions spanned by PCR primers using raw sequence reads.

Our eLetter github.com/caseywdunn/s... responding to a recent Science paper was just posted. The paper found more genes with consistent support for sponge-sister than ctenophore-sister. We found several technical issues that, when corrected, reverse the conclusions and recover ctenophore-sister.

As the Gulf Stream carries man o’ war colonies north, winds push them on shore 🏖️, causing strandings along the U.S. East Coast - from Florida in the winter to New England in the summer.

Our new paper on structure and growth of Porpita porpita - rdcu.be/etcY6 . Like Velella and Physalia, this is a colonial cnidarian that floats at the surface of the Ocean. The whole colony arises form a single embryo through clonal growth that gives rise to many specialized bodies.

Our chromosome-scale genome assembly of Nanomia septata, a siphonophore - doi.org/10.1101/2025... . Much larger than many other cnidarian genomes, fewer chromosomes, and highly rearranged. No smoking gun for how they achieve complex colony-level organization. Great work Namrata Ahuja and friends!

Even on a dive boat, sometimes the most spectacular displays are above water. This was from when @caseywdunn.bsky.social and I were on a small liveaboard off Komodo, Indonesia. I like the offset paths of the double-flash on the right.
