- newParents’ stress may be quietly driving childhood obesity, Yale study finds
A Yale study found that lowering parent stress can help protect young children from obesity. When parents practiced mindfulness and stress-management skills, their kids showed healthier eating patterns and avoided the weight gain seen in families that only focused on diet and exercise.

- newBrain scans reveal how ketamine quickly lifts severe depression
A new brain-imaging study has revealed how ketamine produces its fast antidepressant effects in people with treatment-resistant depression. Researchers tracked changes in a critical brain receptor that helps neurons communicate and found that ketamine reshapes its activity in specific brain regions tied to mood and reward. These shifts strongly matched improvements in patients’ symptoms. The findings could help scientists develop better ways to predict who will benefit from ketamine therapy.

- new165,000 dementia patients reveal hidden stroke risk from common drug
A massive UK study of more than 165,000 dementia patients has uncovered troubling new evidence about risperidone, a commonly used drug for severe agitation. Researchers found the antipsychotic increases stroke risk in dementia patients across the board—including those with no prior heart disease or stroke—challenging the long-held belief that some patients might be safer candidates than others. Because risperidone is the only drug of its type licensed for dementia, doctors often use it as a…

- newScientists say this simple diet change could transform your gut health
A growing trend called “fibermaxxing” is putting dietary fiber in the spotlight—and for good reason. Fiber plays a powerful role in keeping the body healthy, from supporting digestion and feeding beneficial gut microbes to helping regulate blood sugar and cholesterol. Researchers say getting enough fiber may even lower the risk of conditions like obesity, diabetes, and certain cancers.

- A new “magic mushroom” drug could treat depression without psychedelic hallucinations
Scientists are exploring a new way to harness the medical promise of psychedelic compounds without the mind-bending side effects. Researchers created modified versions of psilocin — the active form of psilocybin from “magic mushrooms” — that still target key serotonin pathways linked to depression and other brain disorders but appear to cause far fewer psychedelic-like effects.

- Scientists discover hidden brain cells that may stop Alzheimer’s tau buildup
Scientists have uncovered a surprising new role for little-known brain cells called tanycytes that may influence the development of Alzheimer’s disease. These specialized cells appear to help remove toxic tau protein from the brain by transporting it from the cerebrospinal fluid into the bloodstream. When tanycytes become damaged or dysfunctional, tau can accumulate in the brain, a hallmark of Alzheimer’s.

- Scientists finally reveal why mint feels cold
Scientists have revealed how the body’s microscopic cold sensor, TRPM8, detects both chilly temperatures and the cooling effect of menthol. The discovery finally shows how the sensation of “cool” works at the molecular level—and could inspire new treatments for pain and eye disorders.

- Study finds phone use on the toilet may cause painful medical condition
Scrolling on your phone while sitting on the toilet might be doing more harm than you think. A new study found that people who use smartphones during bathroom visits had a 46% higher risk of hemorrhoids compared to those who don’t. Researchers discovered that phone users tend to spend significantly longer on the toilet, often getting distracted by news or social media, which may increase pressure on anal tissues.

- Scientists discover a brain signal that may trigger autism’s domino effect
Researchers have uncovered a surprising molecular chain reaction in the brain that may play a role in some forms of autism. The study suggests that nitric oxide, a tiny signaling molecule normally involved in fine-tuning communication between brain cells, can sometimes trigger a cascade of changes inside neurons. When nitric oxide activity rises, it can alter a protective protein called TSC2, weakening an important cellular brake and allowing the mTOR pathway, which controls growth and protein p…

- Golden Retriever genes linked to anxiety, aggression, and intelligence in humans
Scientists studying 1,300 golden retrievers have uncovered genetic clues explaining why some dogs are more anxious, energetic, or aggressive than others. Remarkably, several of the same genes linked to canine behavior are also tied to human traits like anxiety, depression, and intelligence. The discovery suggests dogs and humans share biological roots for emotions and behavior. Understanding these links could help owners better interpret their pets’ reactions and even improve training and vete…

- Mayo Clinic discovers rare gene mutation that causes fatty liver disease
Mayo Clinic researchers have identified a rare mutation in the MET gene that can directly cause metabolic dysfunction-associated steatotic liver disease. The mutation disrupts the liver’s ability to process fat, leading to inflammation, scarring, and potentially cirrhosis. The discovery began with a father and daughter who had the disease without typical risk factors. Large-scale genomic data suggests similar rare variants may quietly contribute to the disease in many more people.

- Scientists create cartilage scaffold that helps the body regrow bone
Researchers in Sweden have engineered a cell-free cartilage scaffold that can guide the body to rebuild damaged bone. By removing the cells but preserving the structure and natural growth signals, the material acts as a blueprint for the body’s own repair process. In animal studies, it helped regenerate bone without triggering strong immune reactions. The team now plans to scale up production and begin testing the approach in humans.

- Scientists discover protein that triggers diabetic blindness
A newly identified protein may hold the key to preventing diabetic blindness. Researchers discovered that LRG1 triggers the earliest damage in diabetic retinopathy by constricting tiny retinal blood vessels and reducing oxygen supply. In mice, shutting down this protein stopped the damage before it could take hold. The finding could pave the way for treatments that protect vision before symptoms ever begin.

- A 4,000-year-old sheep reveals the secret of an ancient plague
A mysterious form of plague that spread across Eurasia thousands of years before the Black Death has finally revealed a crucial clue. Scientists analyzing ancient DNA discovered the bacterium Yersinia pestis in a 4,000-year-old domesticated sheep from a Bronze Age settlement in the Ural Mountains—the first time the pathogen has ever been found in a non-human host from that era. Because this early strain couldn’t spread through fleas like the medieval plague, researchers have long puzzled ove…

- Boosting a key brain protein could help treat Rett syndrome
Researchers have discovered a new way to increase a key brain protein damaged in Rett syndrome, a rare genetic disorder that affects thousands of children worldwide. Early studies in mice and patient-derived cells show the approach can restore normal brain cell function, raising hopes for future therapies.
