Sep. 22, 2026 — Caffeine may make sleep less restorative even when you fall asleep normally and stay in bed for eight hours, with EEG recordings revealing fewer of the slow brain waves associated with deep sleep. Individual sensitivity varies dramatically, meaning ...

Sep. 21, 2026 — Researchers have found evidence that long COVID may damage dopamine releasing neurons in the brain, potentially explaining persistent fatigue, low motivation, slowed movement, and memory difficulties. The discovery could lead to new treatments that ...

Sep. 21, 2026 — Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar ...

Sep. 21, 2026 — A new needle-thin brain implant can record neural activity, deliver drugs, and stimulate multiple brain regions using a single flexible fiber. Successful tests in mice suggest it could give ...

Sep. 21, 2026 — Scientists have found that the human brain develops from two distinct cellular systems, suggesting that evolution fused together two ancient nervous systems with very different jobs. The discovery ...

Sep. 19, 2026 — Complex systems may work better when their parts are not perfectly alike. Northwestern physicists found that carefully balanced variation, or “disorder,” can make networks such as power grids, ecosystems, neurons, and materials more stable. Even ...

Sep. 18, 2026 — Newer blood thinners may do more than prevent strokes in people with Alzheimer’s disease and atrial fibrillation. Researchers found that patients taking NOACs experienced a slower decline in ...

Sep. 18, 2026 — Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while ...

Sep. 17, 2026 — Scientists discovered that brain-cell axons may not be smooth tubes as textbooks have shown for more than a century, but instead naturally resemble strings of tiny pearls. Those pearl-like structures can change with neural activity and may help ...

Sep. 16, 2026 — Scientists discovered a hidden “immune organ” inside the skull that acts as a rapid first responder against brain cancer in mice. Strengthening this local immune defense improved tumor rejection and survival, raising the possibility of new ...

Sep. 16, 2026 — Scientists reconstructed videos from the brain activity of mice, producing 10-second clips based only on signals from neurons in the visual cortex. The breakthrough could help reveal how the brain reshapes what we see before it becomes our ...

Sep. 15, 2026 — Simply smelling chocolate helped men complete more leg extension repetitions without making the workout feel harder, with dark chocolate producing the strongest effect. The researchers think familiar food aromas may influence appetite and motivation ...
