Sending fan mail via social media: I loved this review by @msobol.bsky.social and @carolinamicro.bsky.social "Tracing ancient life through the genomic record" It's so good. For example, how to account for things like HGT in prok evolution, esp over geologic time scales? doi.org/10.1093/jamb...

DON'T GET ALL EXCITED AND ASSUME GOOD WILL. This is an effort to rebrand already appropriated dollars and already developed programs before the midterms so they have something they can use against being called anti-science. THIS IS NOT NEW INVESTMENT. THESE ARE NOT NEW DOLLARS FOR SCIENCE.

The Senate has taken the first step toward preventing the White House's proposed research funding regulations from taking effect. The measure now moves to the full legislative process. Read more: www.ascb.org/science-policy/first-s…

New Evolution Digest out! 🎉 Does balancing selection maintain fitness variance? Yes, when drift and environmental fluctuations are in play! I discuss why this matters for plant adaptation to climate change. 🌱🌡️ doi.org/10.1093/evol... @sse-evolution.bsky.social @journal-evo.bsky.social

Digest: Drift and environmental fluctuations reveal fitness variance under balancing selection
Abstract. Why natural populations harbor high additive genetic variance for fitness remains an evolutionary puzzle. Connallon and Czuppon (2026) show that

@carolinamicro.bsky.social Huang & @lbobay.bsky.social investigated genomic rearrangements across 121 microbial species, showing that rearrangements occur at a variable pace across bacteria and archaea, pointing to different selective constraints. 🔗 doi.org/10.1093/gbe/evag002 #genome #evolution

NSF needs to hear from you. Among other points, I suggested: keep politics out of science; stop using the threat of cancelling scientific grants to try to control universities; increase NSF funding for fundamental research. Pls send around. Deadline is January 27. Thanks www.nsf.gov/od/updates/n...
