A tremendous loss. Philippe was incredibly kind, human, a visionary scientist and a wonderful mentor. His team, the department of Immunology @immunopasteur.bsky.social and more broadly @pasteur.fr mourns a great mind.

That's a wrap ! Beautiful science, lively discussions and a really amazing community, it was a real pleasure to organise with @magalisuzanne.bsky.social this first cell extrusion meeting #CellExIt1. Looking forward number 2 !

I don't see why the number of application will go down in the coming year if this is related to reduction of funding in the US + AI assisted grant drafting. This is going to be a long lasting pb so I would expect this to be maintained for some years...

Not mentioning subconscious bias and how this could influence the profile of people allowing themself to apply (this will surely influence the social metrics of who is applying)

Applying for an ERC grant in the 2027 competitions: what you need to know The ERC plans to launch the grant competitions under its 2027 Work Programme between July 2026 and June 2027, with the calls for proposals introducing several changes to the eligibility rules for appl...

I understand the rational of the problem of handling more applications, but this very harsh 2 year ban will surely amplify bias of self inhibition for applying and reinforce existing bias regarding application profiles... I am sure there are other ways...

AI badly needs a dose of skepticism Some scientists are too eager to believe their own claims

AI is powerful, but hype gives it pseudoscience vibes.

When claims are unfalsifiable, detached from reality, or driven by tools looking for problems, we risk undermining real progress.

Overselling AI does not accelerate science: It erode trust.

Choanoflagellates — our closest animal relatives — form multicellular colonies in two ways: cell division AND aggregation.

This previously unknown "mixed multicellularity" suggests our animal origins are more complex than thought.

I saw that many time as reviewer and systematically inform the editor (even if I get to see the other reports after editorial decisions is sent). IMO people doing this should just be banned from reviewing considering all the harms it can do to authors

Now the sky is the only limit 🤩
