Sep. 4, 2026 — 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 ...

Sep. 4, 2026 — 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 ...

Sep. 3, 2026 — 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, ...

Sep. 3, 2026 — 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 ...

Sep. 2, 2026 — Some of the attention patterns that make ADHD challenging may also help spark creativity by allowing the brain to explore more ideas and unexpected connections. Researchers think creative activities could potentially channel this “defocused ...

Sep. 2, 2026 — Brain changes associated with Alzheimer’s may begin at least seven years before amyloid plaques become detectable with current PET scans. Researchers uncovered the signal by tracking healthy older adults with repeated brain imaging over nearly 20 ...

Sep. 1, 2026 — Mindfulness, gratitude, and optimism training may improve blood pressure, inflammation, and other heart-health measures within just eight to 12 weeks. The strongest programs paired daily practice with regular reinforcement, suggesting that improving ...

Sep. 1, 2026 — A study of people over 90 found that dementia risk remains strongly shaped by sex, race and genetics, with women and black participants facing notably higher risks. Intriguingly, some people stayed cognitively healthy despite carrying major risk ...

Aug. 31, 2026 — Scientists discovered that human microglia, immune cells that help shape developing brain circuits, can take four to eight years to mature instead of just weeks as they do in mice. The unusually slow process may help explain how the human brain ...

Aug. 30, 2026 — Adults aged 40 and older performed about 12% faster on a test of executive function after using a HEPA air purifier at home for one month. The findings suggest that cleaner indoor air could offer a simple way to help protect the brain from the ...

Aug. 28, 2026 — Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal ...

Aug. 27, 2026 — Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurrence and led to 100% survival at 60 days, though it ...
