Aug. 29, 2026 — A ketogenic diet outperformed Mediterranean and low-fat diets in several measures of metabolic health during a clinical trial involving people with obesity, prediabetes, and fatty liver disease. All three groups lost about 10% of their body weight, ...

Aug. 29, 2026 — Dogs and humans may have more in common when it comes to aging than scientists realized. Researchers with the Dog Aging Project found that patterns of small molecules in dogs’ blood were linked to longer or shorter lifespans in remarkably similar ...

Aug. 29, 2026 — People with chronic insomnia who used melatonin long term had a roughly 90% higher risk of developing heart failure over five years, according to a large preliminary study. The findings do not prove melatonin causes heart problems, but they raise ...

Aug. 28, 2026 — Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal ...

Aug. 28, 2026 — Scientists have identified a protein that acts like a brake on the nervous system’s ability to repair damaged connections. Blocking AHR helped injured nerve fibers regrow and improved movement and sensation in mice with nerve or spinal cord ...

Aug. 28, 2026 — Scientists have created light-activated drugs that helped blind mice perceive light again and restored visually guided behavior without gene therapy, implants, or specialized lighting. Even more intriguingly, two of the most promising compounds ...

Aug. 28, 2026 — A popular vanilla flavoring in e-cigarettes may interfere with some of the earliest steps of human development. In lab experiments, vanillin caused embryonic stem cells to lose their ability to develop normally and pushed them toward forming only ...

Aug. 28, 2026 — Every one of 212 plant-based meat alternatives and drinks tested in the UK contained at least one naturally occurring fungal toxin, though concentrations remained below recommended EU guideline ...

Aug. 27, 2026 — Ultra-processed foods make up a huge share of the American diet, and new research suggests they may carry another serious health risk for men. In a nationally representative study of more than 17,000 U.S. men, those who ate more ultra-processed ...

Aug. 27, 2026 — The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not prevent most people from catching a cold, although ...

Aug. 27, 2026 — Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurrence and led to 100% survival at 60 days, though it ...

Aug. 27, 2026 — Researchers discovered a brain-based “brake” that can shut down chronic nerve pain in mice by calming an overactive pain circuit. Targeting this system more precisely could one day lead to powerful pain relief without affecting opioid receptors ...
