Jan. 18, 2026 Scientists have discovered that breast cancer can quietly throw the brain’s internal clock off balance—almost immediately after cancer begins. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the brain-body feedback loop that regulates stress, sleep, and immunity. Remarkably, when researchers restored the correct day-night rhythm in specific brain neurons, ...

Jan. 18, 2026 Researchers have identified OTULIN, an immune-regulating enzyme, as a key trigger of tau buildup in the brain. When OTULIN was disabled, tau vanished from neurons and brain cells remained healthy. The findings challenge long-held assumptions about tau’s necessity and highlight a promising new path for fighting Alzheimer’s and brain aging. Scientists now believe OTULIN may act as a master ...

Jan. 18, 2026 A long-running Swedish study has followed adults for nearly five decades, uncovering when physical decline truly begins. Fitness and strength start slipping around age 35, then worsen gradually with age. The encouraging twist: adults who began exercising later still improved their physical capacity by up to 10 percent. It’s a powerful reminder that staying active matters, even if you start ...

Jan. 17, 2026 Thyme extract is packed with health-promoting compounds, but it is difficult to control and easy to waste. Researchers created a new technique that traps tiny amounts of the extract inside microscopic capsules, preventing evaporation and irritation. The method delivers consistent nanodoses and could eventually be used in medicines or food products. It may also work for many other natural ...

Jan. 15, 2026 Tryptophan does far more than help us sleep—it fuels brain chemistry, energy production, and mood-regulating neurotransmitters. But as the brain ages or develops neurological disease, this delicate system goes awry, pushing tryptophan toward harmful byproducts linked to memory loss, mood changes, and sleep ...

Jan. 15, 2026 Spikes in blood sugar after eating may be more dangerous for the brain than previously thought. In a massive genetic study, people with higher post-meal blood sugar had a much greater risk of Alzheimer’s disease. The effect couldn’t be explained by visible brain damage, suggesting hidden biological pathways may be involved. Researchers say managing blood sugar after meals could become a key ...

Jan. 12, 2026 Researchers have discovered a brain activity pattern that can predict which people with mild cognitive impairment are likely to develop Alzheimer’s disease. Using a noninvasive brain scanning technique and a custom analysis tool, they detected subtle changes in electrical signals tied to memory processing years before diagnosis. The findings point to a new way of spotting Alzheimer’s ...

Jan. 8, 2026 A large review of studies suggests that exercise can ease depression about as effectively as psychological therapy. Compared with antidepressants, exercise showed similar benefits, though the evidence was less certain. Researchers found that light to moderate activity over multiple sessions worked best, with few side effects. While it’s not a cure-all, exercise may be a powerful and accessible ...

Jan. 16, 2026 A new study warns that a widely used eye ointment can damage a popular glaucoma implant. Researchers found that oil-based ointments can be absorbed into the implant’s material, causing it to swell and sometimes break. Patient cases showed damage only when the implant directly contacted the ointment, a result confirmed in lab experiments. The findings raise concerns about standard post-surgery ...

Jan. 12, 2026 Most U.S. adults have risk factors tied to a little-known condition called CKM syndrome, which connects heart disease, kidney problems, diabetes, and obesity into one powerful health threat. When these issues overlap, the danger rises far more than when they occur alone. Despite low awareness, people are eager to learn how CKM is diagnosed and treated. Experts say understanding how these systems ...

Jan. 12, 2026 Weight-loss drugs like Ozempic and Wegovy are changing how Americans spend money on food. A large Cornell study found households cut grocery spending by over 5% within six months, with even bigger drops at fast-food restaurants. Snack foods and sweets saw the steepest declines, while only a few categories like yogurt and fruit rose slightly. The effects linger for at least a year among continued ...

Jan. 11, 2026 Roasted coffee may do more than wake you up—it could help control blood sugar. Researchers discovered several new coffee compounds that inhibit α-glucosidase, a key enzyme linked to type 2 diabetes. Some of these molecules were even more potent than a common anti-diabetic drug. The study also introduced a faster, greener way to uncover health-boosting compounds in complex ...
