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.

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 History of Transposable Element Invasions in Drosophila melanogaster #Drosophila

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

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 🧪

Please share your "AI" policies, for classrooms, undergraduate researchers and graduate researchers in your lab with me to help me develop one for my lab. I have seen several of you share some really thoughtful documents over the past few months, but I forgot to save the posts. Thank you!

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...

Happy to share the lab’s latest preprint! Led by PhD student @isaiahwill.bsky.social, we hope that this thorough characterization of expression patterns for many #drosophila fat body driver lines will be a useful resource to the fruit fly community.

Every reviewer wants a shorter paper, containing three additional papers

Meanwhile excellent scientists across Canada are shuttering up their labs and unable to pay trained staff because the CIHR budgets have not kept pace with inflation. I have nothing against the new recruits, I just wish that 🇨🇦 wanted to support all the folks aready here trying to advance knowledge.

With @ewanflintham.bsky.social @thomaslesaffre.bsky.social and @sarperotto.bsky.social we've been thinking about what theory tells us about sexual antagonism (SA = when selection favours different trait values in females and males). Our review is here: tinyurl.com/ct5mk8mv

My PhD advisor, Adam Jones made G-matrices super intuitive to me. He's got some good papers that are easy to read. Also a software GUI for easy modeling. Might help how to intuit changes with having to get too under the hood. doi.org/10.1093/jher...
