@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.

כולם עסוקים במהפכה באיראן תהיה או לא תהיה וכמה אולי ימותו. אבל לפני שבוע היתה מהפכה אמיתית, מוכחת, יוצאת דופן, שעוד תציל מיליונים. אבל מהפכה אופטימית קצת פחות מעניינת. מקפיץ שוב את הציוץ. זה באמת הרבה יותר חשוב לאנושות.

הבוקר בשורה פורצת דרך באונקולוגיה. החלבון p53 מונע התפתחות סרטן, ובהרבה סרטנים הוא עובר מוטציות שונות ומתפרק. תרופה חדשה מצליחה לייצב אותו, למנוע התפרקות שלו וככה לעצור את הסרטן. התרופה יעילה רק נגד מוטציה אחת לא הכי נפוצה, Y220C, אבל ככה מתחילים. nejm.org/doi/full/10.10…

I am honored to have been elected to the Association of American Physicians (AAP) — one of the highest honors in academic medicine. AAP membership is limited to 70 physician-scientists per year and recognizes outstanding contributions to biomedical research. 🎉 What this means for the field of Geroscience is that it is finally being accepted by the more established fields of medicine. I consider this good progress! I would like to express sincere thanks to all who have taken part in my journey — sharing ideas, encouragement, laughter, and fun.

מדובר רק בתאים במעבדה, לא ראיתי שחזרו על התוצאות, לא הייתי מסיק מכך כלום על בני אדם עדיין. פשוט מעניין.

SIRT6 decline throws Off Mood, Sleep, and Cognition. rdcu.be/eTvJj Tryptophan byproducts build proteins, NAD+, and neurotransmitters (serotonin and melatonin). Yet, in aging and neurological disease, this balance is lost, leading to impaired mood, learning, and sleep.

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/sta…

@Dr_Singularity We suggested this idea 10 years ago and showed that Bcl2 family inhibitors eliminate senescent cells in the skin. Directed elimination of senescent cells by inhibition of BCL-W and BCL-XL | Nature Communications share.google/RYdUQ0vKkqNV9Y…

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.
