Hermes Agent is shrinking the distance between a scientific idea and testing it. Thank you @NousResearch and @Teknium for building it.

Weaponized incompetence is pretending not to know how to do something until the person affected by your failure does it for you. Strangely, the competence returns when the consequences do.

Intelligence is on tap. Access is abundant. Discernment is not.

Brains do not age uniformly. Our models should not pretend they do.

We spent 70 years teaching computers to follow instructions. Now we’re teaching them to use judgment—and discovering that most “instructions” were undocumented judgment calls all along.

The future arrived early and immediately asked us to verify we’re human.

Is it reasonable to expect that at a conference centre with ~4000 participants, my laptop's Wi-Fi would work in the plenary?

Does brain aging always mean vessel loss? 🧠We found a surprising hypervascularization, driving cognitive decline & blood-brain barrier damage in aging. 👇🧵biorxiv.org/content/10.64898… Led by @MihailMuc

Glymphatic dysfunction in Alzheimer’s disease: A critical appraisal

Thirteen years after the initial publication defining the glymphatic system, we critically reappraise the role of its dysfunction in Alzheimer’s disease (AD). Our understanding of glymphatic function...

Which foods have the highest amounts of NAD boosters? 1. NMN - broccoli, beetroot, green beans 2. NR - oranges, bananas 3. NAD+ - collard, spinach, parsley, cabbage But - 100 g of broccoli has only 14 mg of NMN vs. a dose that lowers cholesterol, BP & trigs of 1000 mg/day

Short-chain fatty acids (SCFAs) promote gut health, lower inflammation and might promote longevity. New study reports sugary drinks are associated with fewer gut bacterial species that make SCFAs @Cell_Metabolism 🧵

What a disappointment today. Can we not work together as North Americans to create an international jurisdiction force to address drug traffickers and other criminals that exploit the fact that we have separate countries and borders.. Instead of a trade war where everyone loses

Prolonged utilization of fat as a fuel promotes cellular senescence during aging! science.org/doi/10.1126/scia…
Mitochondrial fatty acid oxidation drives senescence

Mitochondrial fatty acid oxidation drives senescence

Nuclear DNA damage activates fatty acid–fueled mitochondrial energy metabolism to induce cellular senescence, a hallmark of aging.
