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!

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!

Well done @timjanicke.bsky.social and colleagues, looking good !

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

A new study by Evin et al. @isemevol.bsky.social with Colline Brassard #MECADEV in Science reveals that dogs already exhibited a wide variety of shapes and sizes more than 11,000 years ago, long before modern breeding practices. www.science.org/doi/10.1126/...

Check out the paper explaining what this is about, and also the database itself!

I was quite impressed and humbled yesterday to give a talk at the @linneansociety.bsky.social, in front of this very portrait and plate!

Very proud to see this work highlighted by the journal! Publishing in Evolution has always meant something special to me. Congrats to the first author Sylvain Pouzet who found the energy to keep on working on his master project during his PhD.

Genetic architectures of #ComplexTraits vary widely. @yuvalsim.bsky.social @jkpritch.bsky.social @gs2747.bsky.social &co show these diffs arise from mutational target size & heritability per site; when controlled for, all tested traits have similar architectures @plosbiology.org 🧪 plos.io/47mZXqT

Nicolas Sarkozy a raison : ce n’est pas lui qu’on humilie, c’est la France. Mais pas au sens où lui l’entend… www.mediapart.fr/journal/fran...

Global warming is not a “con job.” It is a fact. In the face of Donald Trump’s new denial of climate change, CNRS scientists have reacted by pointing to the facts and levers for action to halt this planetary crisis.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/... ), we find the opposite: animals exchange genes more, and for longer, than plants

Looking forward to speaking @dzg2025berlin.bsky.social in Berlin on Anthropocene Biology in Eastern Europe and Beyond. I will talk about the implications of #war on wildlife. Sadly, science meets reality when my departure to Berlin was delayed due a #drone attack in Poland.

Absolutely stunning story! I'll just drop this line here: "Clonal males may thus be regarded as organelles at the superorganism level, resulting from the integration of this alien genome into a colony that directly replicates it."

Why do males and females often differ in traits? The expected answer: selection. But our new paper in GENETICS shows that genetic drift alone can generate sexual dimorphism — even when male & female optima are the same

The next speaker from our Organismal Resilience symposium is Luis Chevin @lmchev.bsky.social! Luis' work takes a genetic perspective on evolution and ecology. His projects consider a range of species, from theoretical models to observations in the wild. Book to hear from Luis on 20 November 🧪 🌍 👇

Do ectotherms age more strongly in warm environments? And if so, does it mean reduced fitness and population viability in a warmer world? We investigated these questions in a recent study based on an experiment with Daphnia magna (1/7) @t-ergon.bsky.social @biovitenskap.bsky.social

@cnrsecologie.bsky.social regrette profondément l'adoption de cette loi à la vision court-termiste & ses conséquences graves sur l’environnement, qui méprise santé & bien-être de la population & le rôle des espèces sauvages dans la prod. agricole. La communauté scientifique n'a pas été entendue.
