If you are at #Sfn2025, come find us at the BRAIN Toolmakers Social (Sunday, 11/16, 7-9:30 pm). Learn about our simulation tools BMTK, SONATA, and VND - useful for building, sharing, and visualizing bio-realistic simulations of brain circuits! https://t.co/gwtZHnZb1L

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!

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

Happy science fact of the day: It's a year since the first Imaging Neuroscience paper was published, with 280 papers since then. Hence in just the first year, over half a million dollars has stayed within academia, rather than going to Elsevier [shareholders etc].

I guess only companies will be able to afford to apply machine learning and AI to the @uk_biobank freezing out academic labs. Maybe that’s not the intent of this policy but that will be the consequence.

In people w/ Alzheimer's, blood vessels are tortuous and irregular just like what we reported in tau models in 2018. In our new work, we show that there's a lot more perivascular tau than previously thought. Read about clear brains + vascular tau here: https://t.co/Bm3Ipwim6d

Our new lab paper suggests that almost all (between 75-90%) cognitively intact people with abnormal plasma p-tau217 values subsequently developed MCI when followed for <10 years after their blood test. (14% in A-T-) I have mixed feeling of being happy and scarred... 😳#Alzheimer
