We've updated the Frequently Used GAL4 and Other Binary Drivers resource flybase.org/GAL4/freq_us... with 3 more GAL4 drivers (Scer\GAL4[Adh.PF], Scer\GAL4[c527], and Scer\GAL4[srp.D.cCa]) and added an image to Scer\GAL4[bap.3].

Can mathematics explain how biological patterns are formed? Alan Turing thought so. Join me, @benswedlund.bsky.social , as we explore his reaction-diffusion theory and how it transformed our understanding of pattern formation and self-organisation.

In his seminal 1952 theoretical paper, Alan Turing proposed that partial differential equations, representing molecules (“morphogens”) that react with one another and diffuse through space, can encode spontaneous periodic pattern formation. doi.org/10.1098/rstb...

I followed the definition of Wellman & Strother (2015) for terrestrial taxa, so for these purposes terrestrial includes aquatic, freshwater species. If you don't like that decision - or want to check out sources etc., or modify estimates - all relevant data, code, etc.: 10.5281/zenodo.22766005

I was inspired to put my big boy pants on and do this properly (having used a hand drawn version for a long time) for a talk on terrestrialisation at this years @thepalass.bsky.social meeting - #PalAss26. In that light, here is the same, but with scatterpies showing proportion of terrestrial taxa.

The Tree of Life web project is back! A phylogenetic view of biodiversity way ahead of its time (ca. 1995!), conceived and led by David Maddison, collaborative & human-curated, widely used in teaching. Defunct technology had doomed it until Travis, Danny, and Andrew revived it. 🥳🎉 🧪 #evolbiol

The Tree of Life Web Project is back online! tolweb.org Thanks to Travis Wheeler (@wheelerlab.org), Danny Mandel, and Andrew Lenards, the original programmers for ToLWeb, for retooling the code to work on a modern OS! It is hard for me to believe it lives again.

OTD in 1854, Charles Darwin began sorting his notes in preparation for writing a treatise with the working title “Natural Selection.” He would never publish the book, instead publishing a short “abstract”—titled “On the Origin of Species”—in 1859. 🐋🌱 #HistSTM #evolbio 🧪

Recombination helps evolution—but it can also cause mutations. New theory shows that even small increases in mutation near crossovers can oppose the evolution of higher recombination rates. By @sarperotto.bsky.social and Bret Payseur academic.oup.com/evlett/advan...

Elevated mutation near crossovers inhibits the evolution of recombination

Abstract. Recombination diversifies offspring genomes and helps ensure chromosome segregation during meiosis. Mutation rates are elevated near crossovers d
