Feb. 2, 2026 — Chronic stress can damage the gut’s protective lining, triggering inflammation that may worsen depression. New research shows that stress lowers levels of a protein called Reelin, which plays a key role in both gut repair and brain health. ...

Feb. 1, 2026 — When the brain rests, it usually replays recent experiences to strengthen memory. Scientists found that in Alzheimer’s-like mice, this replay still occurs — but the signals are jumbled and poorly coordinated. As a result, memory-supporting brain ...

Feb. 1, 2026 — Middle age is becoming a tougher chapter for many Americans, especially those born in the 1960s and early 1970s. Compared with earlier generations, they report more loneliness and depression, along with weaker physical strength and declining memory. ...

Feb. 1, 2026 — Scientists warn that rapid advances in AI and neurotechnology are outpacing our understanding of consciousness, creating serious ethical risks. New research argues that developing scientific tests ...

Jan. 29, 2026 — Scientists in Sweden and Norway have uncovered a promising way to spot Parkinson’s disease years—possibly decades—before its most damaging symptoms appear. By detecting subtle biological signals in the blood tied to how cells handle stress and ...

Jan. 28, 2026 — A massive international study of more than 3,100 long COVID patients uncovered a striking divide in how brain-related symptoms are reported around the world. In the U.S., the vast majority of non-hospitalized patients described brain fog, ...

Jan. 28, 2026 — Where your body stores fat may matter just as much as how much you carry—especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, ...

Jan. 28, 2026 — AI may learn better when it’s allowed to talk to itself. Researchers showed that internal “mumbling,” combined with short-term memory, helps AI adapt to new tasks, switch goals, and handle complex challenges more easily. This approach boosts ...

Jan. 27, 2026 — A common parasite long thought to lie dormant is actually much more active and complex. Researchers found that Toxoplasma gondii cysts contain multiple parasite subtypes, not just one sleeping form. Some are primed to reactivate and cause disease, ...

Jan. 27, 2026 — Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective ...

Jan. 27, 2026 — Carbohydrates don’t just fuel the body—they may also influence how the brain ages. A large long-term study found that diets high in fast-acting carbs that rapidly raise blood sugar were linked to a higher risk of dementia. People who ate more ...

Jan. 26, 2026 — A new genetic study suggests that obesity and high blood pressure may play a direct role in causing dementia, not just increasing the risk. By analyzing data from large populations in Denmark and the U.K., researchers found strong evidence that ...
