Happy to share our latest work, now on BioRxiv! Here, we determined the cryo-EM structure of the yeast SEAC (GATOR)-EGOC (Ragulator-Rag) supercomplex, providing new insights into the function of this amino acid-sensing hub. biorxiv.org/content/10.110…
How is timely and accurate sister chromatid separation achieved? A process that is happening around 30-50 billion times per minute!!! in the human body needs tight regulation (to avoid cancer development...). paper: lnkd.in/eHCYuyhc comment: lnkd.in/ezyw2dxi
So happy to see this paper of ours online. Special thanks to Ryan Montalvo and RJ for the true team work. sciencedirect.com/science/articl…
Ozempic exists because scientists studied Gila monster saliva. The exact kind of basic research this Administration would have cut without hesitation. Breakthroughs like this happen only if we choose to fund science even if the outcome is impossible to see at the start.
“We’ll lose 125 million pounds by this time next year.” RFK Jr. says the new deal with GLP-1 drug companies will play a major role in helping Americans get healthier. “It’s going to have dramatic effects on human health in this country.”
What a structure!

What @drjohnm sees is that doctors simply accept what guideline writers put into those colored boxes: Which would b fine if guidelines were written by neutral Martians free of dualities of interests. But that’s not the case open.substack.com/pub/johnmandro… @Coronary4front @gbiondizoccai
nearly all the plant-based products we tested had elevated lead levels: vegan powders had 9x as much lead as dairy & 2x as much as beef dairy-based powders had the lowest levels, but half were still too contaminated for safe daily use how could this be? well...
my latest investigation for @ConsumerReports is based on months of reporting and 60+ lab tests of leading protein supplements we found that most protein powders and shakes have more lead in one serving than our experts say is safe to have in a day — some by more than 10 times !
Truly exciting work done in Roger’s group!
We’re looking for an enthusiastic postdoc to join our team. 😊 The project focuses on protein design and cryo-EM applied to cancer research. 🔬🧪 Position funded for 3 years. Please share 🙏 Job description and details (deadline: October 11th): cnio.es/en/empleo/post…

Amazing stuff as always from the Hornberger lab. As much as I love TOR, there are also many other things going on!

🕰️ Is #aging driven by a programmed/programmatic mechanism, or by the unavoidable burden of imperfect maintenance? Our @NatureAging Perspective argues that aging reflects finite maintenance and reduced evolutionary pressure🧵 nature.com/articles/s4358… @schumacherbj @AlexeiMaklakov
I think one issue is that we often conflate the causes of a disease with the reverse direction of effective therapies. I am sitting next to Roy now, I suppose I could ask him!
Much needed for the community!

What if the food you eat every day is slowly damaging your health? We’re surrounded by so many diets and endless advice that is conflicting which leaves most of us confused. So I wanted to sit down with someone who has studied and lived it for their whole life. Dr Andrew…
