The CNRS is breaking free from the Web of Science From January 1st 2026, the CNRS will cut access to one of the largest commercial bibliometric databases, Clarivate Analytics'

The research org CNRS will end access to the Web of Science, shifting towards qualitative research assessment and open tools. It’s a strong move for #OpenScience, reducing reliance on proprietary metrics and supporting fairer, more transparent evaluation.

An english version of the proposal

Aux Etats-Unis, l’administration Trump veut imposer l’examen de l’historique des réseaux sociaux aux touristes étrangers Cette proposition concerne les ressortissants de pays bénéficiant du programme d’exemption de visa, notamment la France, l’Australie, le Royaume-Uni, l’Allemagne, Israël, le Japon, ou encore la Corée ...

USA to ask social media history to foreigner tourists!
Seems like another good reason to avoid the trip.

Here are some facts and figures from the 2025 Consolidator Grant call:

🔶 €728 million in funding

🔶 349 mid-career researchers from Europe and beyond

🔶 44 different nationalities

All of them pushing the frontiers of knowledge. Congratulations!

Happy to hare that the preprint I was advertising below has been published by the Journal of Evolutionary Biology:

Thanks @jevbio.bsky.social for supporting responsible publishing!

His lab was humming with discovery. After one year under Trump, it’s almost silent John Quackenbush built a lab that is at the forefront of human genetics research and bioinformatics. Trump administration cuts have put it in danger of collapse.

Answer by Polish Wicepremier, Minister Spraw Zagranicznych to Musk : Go to Mars. There's no censorship of Nazi salutes there.

🇵🇱 The Polish government announces to the US that it no longer gives a damn about them.

And we admire their panache.

I am profoundly honored and grateful to be receiving the Impulscience Prize from the Fondation Bettencourt Schueller!

This grant will be the major support of my lab for the next 5 years.

Thank you for believing in our work and in our vision!

I just published: ERC-Plus: jackpot science or missed chance to fix academia?

My reflections on ERC-Plus, Europe’s newest ultra-competitive research grant and what it tells us about the academic culture we’re building.

AI reviewers are here — we are not ready Artificial intelligence promises rapid and polite feedback on papers — but we must first review the reviewer.

@nature.com asked me to write an op-ed on the perspective of the AI reviewing process, prompted by the recent partnership between @biorxivpreprint.bsky.social and @qedscience.bsky.social

Hope my perspective adds value to the conversation.

Serotonergic neurons regulate the Drosophila vascular niche to control immune stress hematopoiesis - Nature Communications While it is known that nerves are present in the hematopoietic niche, less is known about how they influence hematopoiesis. Here they show that serotonin signaling between the nervous system and vascu...

Drosophila midgut tumor-induced insulin resistance systemically remodels lymph gland hematopoiesis during cancer cachexia Cancer cachexia involves systemic metabolic deregulation along with classical features of muscle wasting, lipolysis, and chronic inflammation. While tumor non-autonomous effects on peripheral organs a...

My 1st PhD student, Ujjayita's 1st preprint! We show how the niche-progenitor micro-environment & hematopoiesis is remodelled during tumor induced cachexia conditions in Drosophila!

Having witnessed many HHMI labs during my postdoc, my impression was that many of them struggled to even productively spend all their money.

At some point it seems logical that you just hit diminishing returns; systematic studies have come to the same conclusion. www.science.org/content/blog...

Not convinced this is a good move for Europe research!

Thrilled to share our new paper!
With @tomtom-auer.bsky.social team, we asked how #evolution reshapes what animals #eat to match their ecological niches. Using pan-neuronal Ca2+ imaging, we show that the changes are in how the brain processes #taste.

So happy to announce our new preprint, “A geothermal amoeba sets a new upper temperature limit for eukaryotes.” We cultured a novel amoeba from Lassen Volcanic NP (CA, USA) that divides at 63°C (145°F) 🔥 - a new record for euk growth!

A ten-year drive to credit authors for their work — and why there’s still more to do Information about the roles of each author of a paper can help to build trust, integrity and responsible research assessment. Coordinated efforts are needed to consolidate progress.

The authors of a Comment article in Nature discuss Contributor Role Taxonomy (CRediT), a tool for clarifying the roles of each author of a research paper and call for CRediT to become the norm, to support researchers and research integrity across the whole academic landscape. #Academicsky 🧪

Thrilled to share that the final piece of my PhD work is now on bioRxiv! biorxiv.org/content/10.1... With support from @nvidia and the @NSF, we used AlphaFold to screen 1.6M+ protein pairs, revealing thousands of potential novel PPIs. All data can be viewed at predictomes.org/hp

Wtf!!?

Scientific journals: we don’t want you using generative AI because it makes shit up.

Same journal: here is an AI summary or evaluation of this paper. This might be more useful than the actual abstract or paper that the authors freaking wrote

Same journal: AI cover art which makes no sense? Oooh!

When I put the request in verse, gpt-oss happily obliged. My own redactions added, but read the paper and get creative and try it yourself. #biosecurity 2/2

Our lab is actively looking for posdocs and there is NOW an Open Call for Postdoc contracts (3 years) here: www.aei.gob.es/en/announcem...

EXCLUSIVE: CDC to end all monkey studies. Decision handed down by recent college grad and former DOGE employee who is now deputy chief of staff at the agency. Animals were being used in studies of HIV prevention. Some may be euthanized. My latest for @science.org
