Humanity AI Commits $500 Million to Build a People-Centered Future for AI

Folks, this is really important:

Humanity AI Commits $500 Million to Build a People-Centered Future for AI

A broad coalition of philanthropic leaders today announced Humanity AI, a $500M 5-year initiative dedicated to making sure people have a stake in the future of artificial intelligence (AI).

Manipulations génétiques, virus créés par l’IA, bactéries miroirs : quelles limites à la recherche scientifique ? Elles pourraient aider à lutter contre les cancers… mais aussi détruire toute trace de vie sur Terre ! Ce sont les bactéries miroirs. En avez-vous déjà entendu parler ? Et la vie miroir, ça vous dit q...

Proteolytically activated antibacterial toxins inhibit the growth of diverse Gram-positive bacteria Many species of bacteria produce small-molecule antibiotics that enter and kill a wide range of competitor microbes. However, diffusible antibacterial proteins that share this broad-spectrum activity ...

A recent cool preprint by John Whitney's lab on a new family of antibacterial proteins secreted by Gram-positive bacteria that enter and kill a broad spectrum of bacteria. Cell entry is receptor-independent and relies on cleavage by a co-secreted protease and the PMF.

20 years of hard work by the Waksman group in London.
So happy that I could modestly contribute to this scientific adventure.

Open position to work on Type IX secretion (#T9SS) in our lab, in collaboration withe the group of Eric Reynolds at the Dental School of the University of Melbourne. Please spread the word, and forward to anyone potentially interested ! Apply here:

C'est vrai que ce sont les 'Mamadous' qui ont foutu l'hôpital public à terre... Bizarre, pour moi les coupables sont ailleurs... sous les ors de la République.

These people claim they are 'real' Christians. I am no specialist, but I thought the Bible was about welcoming the stranger, caring for the poor, and healing the sick... How do they reconcile their hatred for the majority of humans with their faith? That's a mystery.

Still Time to read this new study form Mathilde Guzzo’s Lab post doc @cjresearch.bsky.social with our structural contribution !

We will have soon an Open position for a PhD thesis position to work on bacterial secretion systems !

Stay tuned !!

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.
