Brain scans reveal which disorders are linked to faster brain aging
A massive MRI study found that Alzheimer’s disease, mild cognitive impairment, psychiatric disorders, and addiction are associated with distinct patterns of accelerated brain aging. The strongest effects appeared in Alzheimer’s and mild cognitive impairment, while ADHD and autism

Vagus Nerve Stimulation Could Help New Skills Stick
Stimulating the vagus nerve after practice helped mice develop stronger long-term motor learning, revealing a potentially important window when the brain is still locking in a new skill. The effect was linked to rhythmic changes in brain blood vessels, hinting that body-to-brain

Cancer-fighting t cells burn out. Scientists may have found a fix
Cancer immunotherapy can lose its punch when tumor-fighting T cells become exhausted, but researchers may have found a way to keep them going longer. Scientists at Memorial Sloan Kettering Cancer Center identified a signaling molecule called MEK that can push T cells to burn thro

The “glue” holding your cells together has a surprising second job
Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, researchers found that cells can dramaticall

Your gut bacteria may reveal how fast your brain is aging
A UCLA study links faster brain aging to specific gut bacteria and chemical byproducts, with older-looking brains also associated with poorer memory, focus, and mood. The findings suggest that biological signs of brain aging may appear decades before obvious symptoms and could ev
