@MunozEspin_Lab @EarlyCancerCam @FrukLab @NatureAging Very nice study! Congrats!

@IdoWolf1 Ido, this a specifc drug for a specific, and rare, mutation. It is not relevant to other p53 mutations, which are, of cause, a major problem in cancer. This is a great breackthrough, but from here to millions is unfortunately a long way to go.

A few weeks ago, I heard the Philharmonic perform in New York, and outside there was a demonstration. It was after the ceasefire, and the people there weren’t protesting Gaza. The signs we saw weren’t about Gaza at all. They were about Israel - about the existence of Israel.

The charade is over. It’s now completely clear that to protest the Philharmonic in Paris by lighting torches, at a moment when Hamas and Israel have already agreed to a ceasefire, is not about stopping the bloodshed. It has nothing to do with humanitarian concerns. It is about hatred. It is about inciting the destruction of Israel. It is about trying to delegitimize anything connected to Israel.

What we are seeing is one of the most ambitious and radical projects of our time: an effort to indict Israel in a way that makes its very existence impossible, and any violence against it - against its citizens or its institutions - morally acceptable and even justified across intellectual and political life. This is a project to incite a new war.

@Dr_Singularity We suggested this idea 10 years ago and showed that Bcl2 family inhibitors eliminate senescent cells in the skin.

@NatureAging @JuliaMMagdalena Thank you Hanna @NatureAging for organizing this exciting focused issue. It was a pleasure to work on it.

[Nature Aging @NatureAging]

🎉Immune aging focus 🎉 @JuliaMMagdalena and @KrizhanovskyLab explore immune surveillance of senescent cells, including mechanisms of clearance, evasion and paracrine senescence, as well as therapeutic strategies https://t.co/2cWxb8evpN https://t.co/BY4sWzq5IQ

It took me more than 10 days before I could enter Ullman and climb to the burnt lab. Heartbreaking. Thankful to @WeizmannScience for helping us get up on our feet and look forward.
