Another fishy #FluorescenceFriday. Even a simple DAPI (blue-yellow) and actin (red) staining can decorate the zebrafish one-day-old embryo spectacularly! 🐟

Thrilled to have my first thesis chapter published in @currentbiology.bsky.social! We combine genomics, gene editing, and performance experiments to reveal the genetic basis and functional consequences of hurricane-induced trait shifts in island lizards! Check it out: www.cell.com/current-biol...
Genomic targets of hurricane-induced selection on clinging performance in an island lizard
Vaughn et al. show that hurricanes drive parallel genomic selection signatures in island anoles. One candidate locus (hs6st1) is associated with rear toe length. CRISPR disruption reduces hindfoot ele...

⁉️ Dear Colleagues: What platforms are you using in your labs using to easily share #code, help students on lab data analyses, and centralize access to pipelines? We do a mix of #bioinformatics and #statistical analyses, using R and other pipelines. We have a linux machine. #Github? #rstudio? THX!!
Tiny Chameleons! By looking at gene family evolution in two South African dwarf chameleons with contrasting forested vs open-canopy habitats, researchers revealed habitat-specific lineages differ in the functional categories genes display across families! doi.org/10.1093/evol... 🌍🧪👇
Are there grants to support small natural history/teaching collections? A little would go a long way to securing some valuable specimens we have at this PUI. But the funding landscape keeps shifting - any leads appreciated! #museum #naturalhistory #ornithology #PUI
#JMIH26 is just a little over a week away. If you're attending, be sure to check out the symposium @danpaluh.bsky.social and I organized celebrating the career and legacy of Aaron Bauer! It will be filled with amazing talks about geckos, snakes, skinks, and more!

Excited to share the final published version of our work on the evolution of dorsal-ventral patterning in fins and limbs, now up on @currentbiology.bsky.social In review we added new single LARM element deletions to assess their impact on dorsality. Take a look! 🔬🧪🐟🐁 www.cell.com/current-biol...
We take for granted that our hands have two sides and can articulate in an endless number of ways. But what about a fish’s fin? Can a fish know something “like the back of its fin,” or have its future told with a fin palm reading? Check out this bluetorial to find out 👇🧪🧬🐟 doi.org/10.1101/2025...

"Right now, in some underfunded lab, a scientist is chasing a question that sounds pointless.... No one can say if they will succeed. But a century of experience says that funding people to do this work is a good bet. If we stop making that bet, we will pay for it in cures no one will know to miss."

New in @science.org ...since our first discoveries of early tetrapods, they have been thought of as "amphibians" characterized by aquatic larvae. But is this true? For the first time, we report exceptional fossils of stem tetrapod babies that upend this paradigm. 1/n www.science.org/doi/10.1126/...
Direct development of stem tetrapods across the fin-to-limb transition
Modern amphibians are characterized by an aquatic larval stage that ends abruptly with a period of widespread tissue remodeling (metamorphosis) upon transition to terrestrial adulthood. A transient la...
