Resetting the body clock could help the brain recover after stroke

Strengthening the body’s natural daily rhythms helped mice recover after stroke by improving the brain’s waste-clearing system and reducing lingering inflammation. The approach worked even when treatment began three days after the stroke, suggesting circadian-based therapies could eventually offer a new way to support long-term recovery.

Scientists found a surprising driver of Alzheimer’s outside the brain

Scientists found that immune cells contributing to Alzheimer’s-related brain damage may be activated in lymph nodes outside the brain before traveling into the nervous system. Blocking this pathway in mice dramatically reduced neurodegeneration and preserved cognitive abilities, pointing to a potentially more accessible treatment target.

160-million-year-old proteins show surprising power against superbugs

Scientists resurrected antimicrobial peptides from mammals that lived millions of years ago and found that some were more potent against drug-resistant bacteria than modern human versions. These evolutionary relics could provide new clues for designing treatments as antibiotic resistance becomes an increasingly serious threat.
