When myelin breaks down, white matter in the brain deteriorates, a change commonly seen with aging. At the same time, microglia, the brain’s primary immune cells, can shift from protective responders ...

Millions of myelin-producing cells have been mapped in the mouse brain, advancing our understanding of nervous system ...

Older adults with exceptional memories continue to grow new brain cells. A recent study published in the journal Nature shows that this biological process nearly stops in people with Alzheimer's ...

Researchers used single-nucleus RNA sequencing and chromatin accessibility profiling to map human hippocampal neurogenesis ...

Science has identified eight habits to become a “superager” in your twenties or thirties so you can live and work longer—and ...

New research suggests that super-agers generate twice as many neurons as typical older adults. But you don't have to be a ...

Early mammalian ancestors were nocturnal, sleeping during the day while the dinosaurs dominated the land. However, some mammalian lineages, including human ancestors, independently transitioned to ...

Human pluripotent stem-cells (HPSCs)—including human embryonic stem-cells and human induced pluripotent stem-cells—are reshaping the landscape of regenerative medicine.1,2 In Parkinson's disease, ...

Scientists have identified prematurely aged astrocytes in the brains of Alzheimer’s patients, particularly those with the APOE4 risk gene. Their findings suggest that cellular senescence in these ...

Scientists believe they have discovered the key to maintaining extraordinary memory and cognition well past your 80s. Here's what you need to know.

After new research into so called "super agers," neurogenesis, and Alzheimer's was published in a major journal, ABC4 spoke to one of the researchers to understand what it might mean for you.
