A few months ago, @elena-romero.bsky.social published a paper showing that HIV escape from broadly neutralizing antibody 10-1074 is driven by very recurrent mutation. In her latest, she asks - just how soft are the signatures of these sweeps? www.biorxiv.org/content/10.6...

Haplotype and diversity signatures of ultra-soft selective sweeps in HIV-1Many urgent medical and agricultural challenges are driven by resistance evolution via soft selective sweeps of multiple simultaneous mutations. Standard approaches to detect these mutations involve g...www.biorxiv.org

Applications are open for SFI's 2027 Complexity Postdoctoral Fellowships. SFI is looking for recent Ph.D. graduates with strong quantitative and computational skills who want to pursue independent, transdisciplinary research. Deadline: September 30, 2026 Apply: santafe.edu/sfifellowship

Dear microbiome enthusiasts: I'm excited to be moving my lab to New York University this fall (& the NYU Institute for Engineering Health); with joint-appointment @isbscience.org I'm hiring a postdoc @ NYU to look at diet-driven evolution in the gut: apply.interfolio.com/189980 Please share! 🦠🤓

In new study led by @bdadonaite.bsky.social, we show many influenza HAs (H5, H7, H9, H1, H2, H3) can use avian or human MHC-II to enter cells. We then use novel combo of deep mutational scanning & cryoEM to define how H5 HA binds to avian MHC-II. Preprint: doi.org/10.64898/202...

Scientists, especially younger ones, are going to have to come to terms with the idea that “doing science” is no longer enough. We all have to fight for science: what it means, what are its values, and why it matters.

What if an embryo made immune cells before it finished building the tissue they usually come from? In our new preprint, we show that annual killifish embryos specify neutrophils before germ layers are fully resolved. www.biorxiv.org/content/10.6... Huge thanks to my PI, @ohnolog.bsky.social ! 🧵

Early immune cell development precedes gastrulation in annual killifishDuring embryogenesis, cell types arise in a predictable order because developmental regulators act sequentially. But how evolutionary changes in morphogenesis reshape the signaling environments that a...www.biorxiv.org

Excited to see @jonj-udd.bsky.social's fantastic work out @genetics-gsa.bsky.social. Selection in _heterozygotes_ is the primary force shaping allele frequencies of loss-of-function mutations in humans, even in genes only associated with purely recessive diseases. 🧪🧬 doi.org/10.1093/gene...

Allele Frequencies at Recessive Disease Genes are Mainly Determined by Pleiotropic Effects in HeterozygotesAbstract. The classic theory of mutation-selection balance predicts the equilibrium frequency of genetic variation under negative selection. The model preddoi.org

The human genome is no blueprint or algorithm — it’s something else entirely, something living with promiscuous logic. Can new genomic AI models, such as Evo 2 and AlphaGenome, untangle these tricky knots or will the genome confound them, too? www.quantamagazine.org/why-the-huma...

Aggregating many experiments into one zero-shot protein language model score obscures that current models cannot meaningfully rank a set of fit mutations or prioritize new-to-nature functions @clauswilke.com www.biorxiv.org/content/10.6...

Antibody LMs learn what looks antibody-like, but not how selection turns naive germline antibodies into strong binders. @aakarshv1.bsky.social and I are excited to share CoSiNE, a model that learns this germline-to-mature process for variant effect prediction and antibody design. (1/8)

We urge GSA members and the genetics community to submit a public comment on the recently proposed OMB regulations—which pose drastic challenges to the scientific enterprise—by July 13, 2026! Submit your comments here: www.regulations.gov/document/OMB...

This was one of the most complex projects I have ever been involved in. Took us the better part of a decade, but I thoroughly enjoyed every minute of it. Especially the intensive and extensive interactions with @wsdewitt.github.io, @matsen.bsky.social, and @tylernstarr.bsky.social

Out now in Science! Our study challenges long-standing assumptions about transcription factor specificity in eukaryotes. Novel single-molecule measurements of TF behavior in living cells reveal an independence of locus-specific binding from DNA sequence recognition.🧵 www.science.org/doi/10.1126/...
