Fun Fit Fact! ⏰
As we age, we lose power (strength plus speed) at twice the rate of strength alone.
▶️ Watch my amazing rockSTARs (ages 65 to 94) at the Milano Senior Center in Melrose MA demonstrate a few power moves.
Why Power Training Matters:
▪️ Improved Reaction Time — helps prevent falls
🧠 #Brain Boost — may support cognitive #health
👊🏽 Fights #Sarcopenia — combats age related muscle loss
😅 And yes… it is #fun too!

Researchers in Japan and at Seattle's @AllenInstitute have simulated the workings of a whole mouse cortex on a #supercomputer - potentially opening the door to virtual studies of neurological diseases and perhaps even the origins of consciousness. https://www.geekwire.com/2025/simulation-mouse-brain/ #brain #simulation #science #neuroscience #sc25

Japanese researchers have found that people who experience COVID-19 “brain fog” have a higher-than-usual density of a certain neural receptor, a discovery that could pave the way for treatment options. https://www.japantimes.co.jp/news/2025/10/24/japan/science-health/covid-brain-fog-study/?utm_medium=Social&utm_source=mastodon #japan #sciencehealth #covid19 #brain #health
GenAI and what it does to the brain.
Truly excellent "long read" article about genAI and what it does to those who come to rely on it. Well researched, with insightful quotes from thoughtful people.
Good science/tech journalism used to be like that, but on AI topics this has become rare. So much easier for the salaried writer of a mainstream paper just to follow the hype.
The author, Sophie McBain, is listed as a "freelance writer" for Guardian, Times and New Statesman. I am glad she's kept her free mind.

University of New Mexico #scientist is revealing what might be one of the most overlooked causes of #dementia — damage in the #brain tiny #bloodvessels. Dr. Elaine Bearer has created a new way to classify these changes, showing that many people diagnosed with #Alzheimers also suffer from #vascular damage that quietly destroys #brain tissue. Even more surprising, she’s finding #microplastics inside the brain that appear linked to #inflammation & #memory loss. https://www.sciencedaily.com/releases/2025/10/251005085637.htm #healthcare

Researchers linked Long COVID "brain fog" to a systemic increase of AMPA receptors in the brain using PET imaging. Higher receptor density correlated directly with more severe cognitive symptoms and inflammation. This discovery provides a potential biomarker for diagnosis and a new therapeutic target, suggesting drugs that suppress AMPA receptor activity could be an effective treatment.
