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. Remarkably, a single injection restored Reelin levels and produced antidepressant-like effects in preclinical models. The findings hint at a future treatment that targets depression through the gut–brain connection.

MMS has long been promoted as a miracle cure, but new research shows it’s essentially a toxic disinfectant. While it can kill bacteria, it only works at levels that also damage human cells and beneficial gut microbes. Scientists warn that homemade MMS mixtures are especially dangerous due to wildly inconsistent dosing. The study calls MMS a clear case where the risks are high—and the benefits are effectively zero.

Researchers studying nearly 2 million older adults found that cerebral amyloid angiopathy sharply raises the risk of developing dementia. Within five years, people with the condition were far more likely to be diagnosed than those without it. The increased risk was present even without a history of stroke. Experts say this makes early screening for memory and thinking changes especially important.

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 cells lose their stability, and the animals struggle to remember where they’ve been.

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. These troubling trends stand out internationally, as similar declines are largely absent in other wealthy nations, particularly in Nordic Europe, where midlife well-being has improved.

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 for awareness could transform medicine, animal welfare, law, and AI development. But identifying consciousness in machines, brain organoids, or patients could also force society to rethink responsibility, rights, and moral boundaries. The question of what it means to be conscious has never been more […]

Researchers found that small doses of an antibiotic can coax gut bacteria into producing a life-extending compound. In worms, this led to longer lifespans, while mice showed healthier cholesterol and insulin changes. Because the drug stays in the gut, it avoids toxic side effects. The study points to a new way of promoting health by targeting microbes rather than the body itself.
