The results could point toward a long-awaited treatment for one of PTSD’s most distressing and stubborn symptoms. Wed, 05 Aug 2026 23:16:44 EDT https://www.sciencedaily.com/releases/2026/08/260805082450.htm https://www.sciencedaily.com/releases/2026/08/260804034624.htm A simple change in posture may subtly affect how people feel and make decisions. Participants who sat upright reported greater feelings of pride and took more successful risks in a virtual balloon game than those who hunched over. Most did not realize researchers had influenced their posture, helping rule out the possibility that they were merely responding to expectations. The results suggest workplace ergonomics could influence more than physical comfort.

Their unusually fast and localized attack could offer clues for developing targeted treatments against infections and cancer. Wed, 05 Aug 2026 01:10:52 EDT https://www.sciencedaily.com/releases/2026/08/260803080914.htm https://www.sciencedaily.com/releases/2026/08/260803080902.htm Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss. This biological “memory” helps explain why many people regain weight after dieting and why medications such as Wegovy and Mounjaro can help by reducing appetite signals, although their effects may fade when treatment ends. Mon, 03 Aug 2026 23:38:28 EDT https://www.sciencedaily.com/releases/2026/08/260803080902.htm https://www.sciencedaily.com/releases/2026/08/260802223437.htm Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease. They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool.

Eating less protein appears to improve metabolism, reduce inflammation and cellular damage, and activate pathways linked to healthier aging and longer life. Sun, 02 Aug 2026 00:52:01 EDT https://www.sciencedaily.com/releases/2026/08/260801042811.htm https://www.sciencedaily.com/releases/2026/07/260731034204.htm Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate. Researchers believe this self-inflicted damage may help tumors evolve while also creating a potential target for new treatments.

Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk. Every additional 10 years of brain aging raised that risk by nearly 40%. Fri, 31 Jul 2026 03:05:12 EDT https://www.sciencedaily.com/releases/2026/07/260729051540.htm https://www.sciencedaily.com/releases/2026/07/260729051534.htm New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later growth. Researchers say this normal process has been mistakenly treated as an obesity warning sign for 42 years.

Remarkably, one dose of rapamycin improved nearly all of these problems within about two hours. The benefits were temporary, but they suggest that adult brain circuits may remain far more adaptable than previously believed.

It worked when given shortly before or after exposure and also shortened illness and the period when infected animals remained contagious. Researchers say the drug could one day complement vaccination and make outbreaks easier to contain.

Compared with two other common classes of diabetes medications, GLP-1 users had a significantly higher rate of alopecia, though the absolute risk was still low. The hair loss was mainly non-scarring, which means it may be reversible.
