Oct. 20, 2026 — The aging brain may be undergoing a remarkable transformation rather than simply losing its abilities, shifting its focus from remembering details to understanding the bigger picture. Scientists suggest this change could be an evolutionary ...

Oct. 20, 2026 — Scientists have found a promising way to protect the brain from Alzheimer’s-related damage by blocking immune cells that contribute to the destruction of neurons. In mice, the treatment preserved ...

Oct. 19, 2026 — Scientists have discovered why some people with a high genetic risk of Alzheimer’s remain mentally sharp into their 80s, uncovering a rare mutation that protects the brain from harmful protein buildup. The findings reveal a potential new way to ...

Oct. 19, 2026 — Walking just 3,000 steps a day could help slow Alzheimer’s-related brain changes, according to new research. Scientists discovered that physical activity was linked to less buildup of harmful tau proteins and nearly half the cognitive and ...

Oct. 19, 2026 — A discovery in tiny algae led to a Nobel Prize-winning breakthrough that allows scientists to switch brain cells on and off using light. The revolutionary technique has already helped researchers activate memories and is opening new possibilities ...

Oct. 19, 2026 — Scientists have uncovered an unexpected culprit behind sleep loss in Alzheimer’s disease: overactive immune cells in the brain. By temporarily removing these cells, researchers restored more than ...

Oct. 18, 2026 — Eating too much salt may do more than raise blood pressure. It could also harm memory and social behavior. In a new study, Japanese researchers discovered that a soy-derived compound called LPC70 ...

Oct. 18, 2026 — Eating blueberries every day could have surprising effects on mood, according to a small study that found greater reductions in depressive symptoms among older adults who consumed the fruit for three months. Researchers also detected changes in gut ...

Oct. 18, 2026 — A psychedelic compound found in magic mushrooms appears to have an unexpected effect: calming highly aggressive fish. Researchers discovered that low doses of psilocybin significantly reduced aggressive attacks in mangrove rivulus fish without ...

Oct. 18, 2026 — Researchers have uncovered three brain pathways linked to lasting improvements in people receiving deep brain stimulation for severe, treatment-resistant depression. They also discovered that patients who failed to improve after two years shared a ...

Oct. 17, 2026 — Scientists have discovered that a protein linked to youth helps protect the brain’s immune cells from age-related decline. Restoring the protein in older mice improved the cells’ ability to clear ...

Oct. 17, 2026 — Scientists have uncovered a surprising cause of age-related cognitive decline involving brain cells previously thought to be entirely beneficial. As these cells become dysfunctional, they can produce abnormal amounts of myelin, disrupting nerve ...
