Stanford scientists discover a seafood that can reverse signs of aging
A substance found in edible sea squirts appeared to reverse several signs of aging in older mice. Plasmalogen supplements improved memory and learning, strengthened connections between brain cells, reduced inflammation, and even helped the mice grow thicker, darker hair. Research

A longer exhale may push your brain toward bolder decisions
Slow breathing with a prolonged exhale made people more willing to take risks by changing heart activity and increasing the brain’s sensitivity to rewards. The findings suggest that something as simple as controlling your breath can directly influence how you evaluate choices.

Scientists reveal the hidden instructions that build the human brain
UCLA researchers have discovered two powerful influences that help guide how the human brain forms before birth. Radial glia, stem cells responsible for producing much of the cerebral cortex, change their behavior depending on how they process glucose and on physical contact with

New injectable treatment helps the brain rebuild after stroke
Duke researchers developed an injectable scaffold that helped stroke-damaged brains grow new blood vessels, support nerve regrowth, and recover movement in mice. The treatment appears to work partly by recruiting the body’s own immune cells, including neutrophils that may switch

Bats carry dangerous viruses without getting sick. This may be why
Scientists discovered that more than 500 species of vesper bats possess two separate sets of antibody genes, an immune arrangement never before found in mammals. The surprising system could help explain how bats tolerate so many viruses without becoming seriously ill.

One immune switch may help drive aging across the body
Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and memory remain remarkably youthful.
