Dec. 5, 2025 — Regular consumption of polyphenol-rich foods like tea, coffee, berries, nuts, and whole grains may significantly support long-term heart health. A decade-long study of more than 3,100 adults found that those who consistently ate polyphenol-packed ...

Dec. 5, 2025 — A large study found that people with impaired kidneys tend to have higher Alzheimer’s biomarkers, yet they don’t face a higher overall risk of dementia. For those who already have elevated biomarkers, kidney problems may speed up when symptoms ...

Dec. 5, 2025 — Researchers engineered a strained germanium layer on silicon that allows charge to move faster than in any silicon-compatible material to date. This record mobility could lead to chips that run cooler, faster, and with dramatically lower energy ...

Dec. 4, 2025 — Researchers found that people with anxiety disorders consistently show lower choline levels in key brain regions that regulate thinking and emotions. This biochemical difference may help explain why the brain reacts more intensely to stress in ...

Dec. 4, 2025 — Researchers studying people with major psychiatric disorders found that drinking up to four cups of coffee a day is associated with longer telomeres. This suggests a potential slowing of biological aging by about five years. However, drinking five ...

Dec. 4, 2025 — Scientists have captured a never-before-seen, high-resolution look at influenza’s stealthy invasion of human cells, revealing that the cells aren’t just helpless victims. Using a groundbreaking imaging technique, researchers discovered that our ...

Dec. 3, 2025 — A unique vaccine rollout in Wales gave researchers an accidental natural experiment that revealed a striking reduction in dementia among seniors who received the shingles vaccine. The protective effect held steady across multiple analyses and was ...

Dec. 2, 2025 — Scientists have discovered that a single gene, GRIN2A, can directly cause mental illness—something previously thought to stem only from many genes acting together. People with certain variants of this gene often develop psychiatric symptoms much ...

Dec. 2, 2025 — As the last Ice Age waned and the Holocene dawned, deep-ocean circulation around Antarctica underwent dramatic shifts that helped release long-stored carbon back into the atmosphere. Deep-sea sediments show that ancient Antarctic waters once trapped ...

Dec. 1, 2025 — Researchers have found a small but powerful switch inside breast cancer cells that helps them survive stressful conditions. When this switch flips, the cells activate protective programs that make them tougher and faster-growing. The finding reveals ...

Dec. 1, 2025 — Scientists have found that common foods can contain hidden contaminants formed during cooking or through environmental exposure. A new testing method called QuEChERS helps identify these chemicals more quickly and with greater ease. The research ...

Dec. 1, 2025 — A high-speed “zap-and-freeze” method is giving scientists their clearest view yet of how brain cells send messages. By freezing tissue at the instant a signal fires, researchers revealed how synaptic vesicles behave in both mouse and human ...
