Black grouse in the French Alps need protection from ski cables. To design better warning flags, Simon Potier, @lienardmarjorie.bsky.social & co discovered that the birds see black & white cheques well, don't see deep red & markers must be no more than 16m apart doi.org/10.1242/jeb....

Discovering what black grouse see to protect them from lethal ski lift cables
There is a silent killer lurking in the French Alps: ski lift cables. Over the last 60 years, the seemingly innocuous wires have accounted for almost 600 recorded landfowl deaths in the region, with b...

New paper out in @jexpbiol.bsky.social! Under the leadership of @lienardmarjorie.bsky.social, we explore the visual system of the Black Grouse and how it plays a role in how the species deals (or not) with human-made structures in its environment. journals.biologists.com/jeb/article-...

Exploring the visual system of the black grouse (Lyrurus tetrix): combining experimental and molecular approaches to inform strategies for reducing collisions
Highlighted Article: Investigation of how black grouse perceive their environment suggests how vision-informed marker design may improve detection of aerial structures and reduce collision risk.

🚨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 www.nature.com/articles/s41... This was a truly collaborative effort! 🧵⬇️

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.

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.

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! www.biorxiv.org/content/10.1...

Perception of Temperature Even in the Absence of Actual Change is Sufficient to Drive Transgenerational Epigenetic Inheritance

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.

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.

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
