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. x.com/visegrad24/status/1986…

"It's just a temporary space until your lab is renovated", Weizmann Institute version. Rebuilding better, and doing so fast. (Photo and tagline: Ziv Shulman)

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.

Nothing can break us!
When we came to see our destroyed labs hit by an Iranian missile, we found that a piano had survived @WeizmannScience

Very interesting study!
New work in @ScienceTM connects immunosenescence and the decline of the thymus during aging with a drop in the ligand RANKL—and shows RANKL treatment restores T cell production and rejuvenates immune responses in aged mice. scim.ag/3OZ6uOE

One very ineresting view on aging clocks and what they can or cannot tell us. 👇 nature.com/articles/s41591-0…

Congrats Nurit. In this stidy we show that p21 might be master regulator of cellular microenvironment with a critical role in fibrosis. Thanks to all the coauthors.
What is the contribution of p21-positive senescent cells to tissue fibrosis? @KrizhanovskyLab @WeizmannScience show that p21 controls not only cell cycle progression but also promotes expression of ECM components and immune invasion embopress.org/doi/full/10.10…

Incredible program to apply to
Attention prospective postdocs! The Azrieli International Postdoctoral Fellowship for Research at Israeli Universities in STEM, Humanities, and Social Sciences is now open for applications! You can apply today for the 2025–26 cohort. The Azrieli International Postdoctoral Fellowship supports the best and brightest minds in their postdoctoral research, connecting them with world-class academics and leading researchers. The fellowship provides generous funding for eligible international applicants to conduct research in any academic discipline at accredited institutions in Israel. The Azrieli International Postdoctoral Fellowships are awarded without regard to religion, gender, age or ethnicity. The fellowship is offered for two years. Renewal for a third year will be considered favourably based on a competitive evaluation process. The fellowship is made up of a basic stipend of ILS 168,000 per academic year, with an additional ILS 20,000 granted annually for research expenses and research-related travel. You can find more details here: azrielifoundation.org/wp-con… And apply here: azrieli.smapply.io/prog/inte… The deadline for application is November 18, 2024. Good luck!

Immunotherapy a key to fight aging? We break down our recent study in this animation! 🧪 Immune checkpoint anti-PD-L1 can enhance the immune system to remove senescent cells & ameliorate age-related phenotypes! nature.com/articles/s41556-0…@JuliaMMagdalena @KrizhanovskyLab @UriAlonWeizmann @IdoAmitLab #Aging #AntiAging #Immunotherapy #Longevity #Healthspan #Immunotherapy4aging @NatureCellBio @WeizmannScience

The business side of academic publishers... The question is what would be a better model?
Major academic publishers' revenue and what they pay authors and reviewers: Revenue: Elsevier: $3.9 billion Springer Nature: $2 billion Taylor & Francis: $800M Wiley: $1.8 billion They pay: Academic authors: $0 Peer reviewers: $0
