Congratulations Felix, @katjareinhard.bsky.social @farrowlab.bsky.social and all involved! Amazing accomplishment !

🚨Very happy that my PhD work is now out in @nature.com!

We discovered that evolution, by acting in the midbrain, shifted the threshold to escape in Peromyscus mice, to fine-tune defensive strategies in different environments

This was a truly collaborative effort! 🧵⬇️

U.S. Tells Court It Plans to Deport Scientist to Russia

The Trump administration intends to deport a Harvard scientist back to Russia, government lawyers told a federal judge on Wednesday. The scientist fled the country in 2022 and fears she will be arrested there over her protest of Russia’s war in Ukraine.

Thank you Sir! Patience is a virtue they say ;-)

Some chemosensors however are too critical to lose: we identify a handful of V1Rs tuned to universal metabolites (steroid & bile-acid sulfates). Deer mouse receptors respond exactly like their mouse counterparts —showing conserved sequence = conserved function

The repertoires of chemoreceptors and their
expression profiles have followed markedly different trajectories during the evolution of the olfactory sensory systems of rodents #Genomics #Evolution #Olfaction

Same smell, different story: 800 deer-mouse odorant receptors have 1-to-1 homologs in mouse and rat, yet only 20 % of V1R & 7 % of V2R orthogroups are shared. Main olfactory path = stable; pheromone path = wild.

The Functional and Genetic Architecture of Olfaction in Deer Mice Mammals have well-developed olfactory systems, but the molecular logic driving the extraction of biological information, how this logic evolves and contributes to differences in behavior remain unclea...

🧬 New study out: we report a chromosome-level assembly of the deer mouse Peromyscus maniculatus! A launching pad for chemosensory-evolution research. Read more 👉 www.biorxiv.org/content/10.1...

Perception of Temperature Even in the Absence of Actual Change is Sufficient to Drive Transgenerational Epigenetic Inheritance Can processes occurring in one individuals nervous system influence the physiology of the descendants? Here we explored the provocative hypothesis that parents sensation or perception of environmental...

Scared to share this after 10 freaking years of waiting, but here we go: We found that temperature *perception* can change the biology of the next generations, even when “it’s just in the parents' head”. Read how C. elegans neurons control epigenetic inheritance!

Single bird flu mutation could let it latch easily to human cells, study finds The potential mutation would allow the avian influenza virus sweeping through cattle herds to attach to a receptor protein on the surface of our cells.

Scientists are reporting that it would take just a single mutation in the version of bird flu that has swept through U.S. cattle herds to produce a virus adept at latching on to human cells, a much simpler step than previously imagined.

Happy VSS submission day to all who celebrate! #VisionScience

Ce traité est nécessaire pour notre industrie, pour la transition écologique… et même pour notre agriculture.

Tant pis pour les fakes news sur le bœuf aux hormones.

Un thread qui ne va pas me faire que des amis. ⤵️

Just put together the beginnings of a systems & behavior neuro starter pack (focus on rodent work) - obviously a lot of people missing, and most included are in my own little bubble, so if you want to be added do reply here! go.bsky.app/Hxpe53o
