A bit of modeling, a bit of experiments, lots of evolution. Researcher @cnrs @cefemontpellier

New paper out @pnas.org: We explore why fly wings evolve along "lines of least resistance" and reconcile the "rate paradox" between population variation and divergence. Check out how a low dimensional model of selection on size explains it all: www.pnas.org/doi/full/10....

We found a viral Trojan Horse: a virus can hide inside another virus.This one surprised us: deltaviruses don’t just borrow a helper virus. They can travel inside it. A literal Trojan Horse “virus-in-a-virus” route into cells. 🤯 Kudos to 1st author @viroscope.bsky.social and co-authors !

Deltaviruses spread through a viral Trojan Horse

Hepatitis D-like satellite viruses, known as deltaviruses, have been recently discovered in a wide range of animals. These viruses are thought to expr…

Researchers in the US might be having feelings about writing grants atm-I know I am! We still need to write them. In this Evolution Exchange, I again chat with Sam Scheiner, who summarizes how to write a competitive proposal. His advice is gold, and helpful regardless of funder. Pls RT!

💬 In the second installment of The Evolution Exchange, retired NSF Program Officer Dr. Sam Scheiner returns to discuss how to craft a successful research proposal. Watch or read the transcript here: www.evolutionsociety.org/the-evolutio...

Thanks to @eseb.bsky.social for funding our proposal for a Special Topic Network on Polygenic Adaptation. Watch out for workshops/seminars and more activities. The STN runs for several years, so we hope this innitiative can sustain the network of oldies and new members of the polygenic community!

How do bacteria deal with double costs? And how costly are unusual levels of mistranslation anyway? In short - antibiotics are more of an issue than less/more mistranslation, but the latter changes how populations deal with antibiotics. For the long story, check out our new paper!

So happy that this work simultaneously measuring the costs of antibiotic exposure and mistranslation is finally out in MBE! Work from @deepaagashe.bsky.social (who was ultra patient!) and my labs. Do see the research highlight here, with Nishant's lovely graphic. academic.oup.com/mbe/article/...

Kudos to @pdevillemereuil.bsky.social for writing a blog post about our paper published earlier this years in the one and only @peercomjournal.bsky.social ! You want to know how genetically variable plasticity is in your fav system, and what components of reaction norm shape vary the most? Try this!

Pierre de Villemereuil@pdevillemereuil.bsky.social · 8mo ago

Took me a year (😱), but I finally published a blog post about our article on the #quantgen variance partition of phenitypic plasticity with @lmchev.bsky.social, published in @peercomjournal.bsky.social. 🇬🇧 devillemereuil.legtux.org/quantitative... 🇫🇷 devillemereuil.legtux.org/fr/genetique...

The Black Death was history's worst documented demographic disaster. New research shows it was also a bizarre anomaly, the unlikely result of volcanic eruptions, multiple consecutive poor harvests in Italy, a war between Genoa, Venice and the Mongols, AND a Black Sea plague outbreak. @science.org

Medieval volcano may have indirectly sparked Europe’s Black Death

Crop failures caused by eruptions possibly forced grain imports from plague-ridden regions
