Learning a new skill triggers both temporary cell swelling and lasting brain growth

BY THE OPTIMIST DAILY EDITORIAL TEAM Did you know that every time the brain learns something, it changes physically? A study in PLoS Biology is the first to track exactly what those changes are, and found two separate processes happening at different speeds and in different locations, and that Read More...

Copper compound targets Alzheimer’s at the blood-brain barrier

BY THE OPTIMIST DAILY EDITORIAL TEAM Most Alzheimer’s research goes after the toxic proteins directly. This study asks a different question: what if the brain’s own clearing system could be fixed instead? Research from Monash University’s Institute of Pharmaceutical Sciences, published Read More...
