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

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.

Le jeudi est le pire jour de la semaine.

As simple as asking Grok or ChatGPT.
We, the scientific community, should have thought about it !!! Such geniuses !!!

Tweet From Obama mentioning my firing from the Washington post. Wirh a photo of me

The last political column I was allowed to write in the @washingtonpost.com was a criticism of Obama.

His people took issue with my piece, but we were respectful.

Now he is tweeting in support of me.

This is how free political speech and respect for debate *actually works*.

Or used to work.

Let’s be clear about what happened to Jimmy Kimmel Trump’s most brazen attack on free speech yet.

After years of complaining about cancel culture, the current administration has taken it to a new and dangerous level by routinely threatening regulatory action against media companies unless they muzzle or fire reporters and commentators it doesn’t like.

We should do the same at @iecb.bsky.social.
So much underestimated potential for modern art in our building !!!
😆🤣

I don’t know what to think about this …

Let’s hope he will be kicked out. Newton and Elon have nothing to do in the same scientific society.

Really excited to share my first paper from the Whitney lab, alongside an amazing grad student, Polina. Here we identify a chaperone family required for the folding of a central domain of T7SS toxins, and solve the structure of the chaperone-toxin complex. www.pnas.org/doi/10.1073/...
