A long-term study found that while a ketogenic diet prevented weight gain, it also triggered major metabolic problems. Mice developed fatty liver disease, abnormal blood fats, and an impaired ability to control blood sugar—especially after reintroducing carbohydrates.…

For most of human existence, listening was closely tied to moments that carried meaning, emotion or survival. Nature supplied the backdrop—wind, water, animals—and music surfaced in hunting rituals, ...

Findings could create new opportunities to treat and study neurodegenerative diseasesScientists discovered that sugar metabolism plays a surprising role in whether injured neurons collapse or cling to life. By activating internal protective programs, certain…

The World Health Organization (WHO) has validated Brazil for the elimination of mother-to-child transmission (EMTCT) of HIV, making it the most populous country in the Americas to achieve this historic milestone.

The World Health Organization (WHO)’s Second Global Summit on Traditional Medicine, jointly organized with the Government of India, opens today, bringing together government Ministers, scientists, Indigenous leaders, and practitioners from more than 100 countries.

Study provides clearest evidence to date to link severe CTE to dementia risk.

“Forever chemicals” known as PFAS have quietly infiltrated everything from nonstick pans to food packaging—and now new research suggests some of them may be speeding up the aging process itself. In a nationally representative U.S. study, two lesser-known…

Baby dinosaurs weren’t coddled like lion cubs or elephant calves—they were more like prehistoric latchkey kids. New research suggests that young dinosaurs quickly struck out on their own, forming kid-only groups and surviving without much parental help, while…

The World Health Organization (WHO) today announced recommendations for the viral composition of influenza (or “flu”) vaccines for the 2026-2027 northern hemisphere influenza season. The announcement was made following a 4-day consultation examining global…

The World Health Organization (WHO) has certified Denmark for the elimination of mother-to-child transmission (EMTCT) of HIV and syphilis, recognizing the country's sustained commitment to ensuring every child is born free of these infections.

Healthy food in schools can help children develop healthy dietary habits for life, according to the World Health Organization (WHO), which released a new global guideline on evidence-based policies and interventions to create healthy school food environments.

Participants in a New Zealand e-bike pilot program say cycling has improved their physical and mental health and helped in managing chronic conditions such as diabetes and asthma, a study from the University ...

Treatments for cardiovascular conditions have never been better. Knowledge about how to improve heart health has steadily improved. Yet, in the U.S., progress in cardiovascular health has largely stalled ...

The most comprehensive study to date into the health effects of collagen supplements found benefits for skin health and significant relief from osteoarthritis symptoms—but no meaningful improvements ...

Has the U.S. Department of Agriculture flipped everything you thought you knew about nutrition on its head? At first glance, the newly released dietary guidelines featuring a new food pyramid may seem ...

Higher levels of blood lactate may be the key to a longer life for people with the neurodegenerative condition ALS, new research suggests. A study at The University of Queensland and Japan's Shiga University ...

At Super Bowl parties, weddings, Independence Day cookouts and Thanksgiving dinners, people celebrate with large spreads of food. When faced with many options, extra food variety increases people's selection ...

Researchers at Nagoya University have created a more efficient iron-based photocatalyst that could reduce the need for rare and expensive metals in advanced chemistry. Unlike earlier designs, the new catalyst uses far fewer costly chiral ligands while still…

Scientists have unveiled a breakthrough way to turn natural gas—long burned as fuel—into valuable chemical building blocks for medicines and other high-demand products. By designing a clever iron-based catalyst powered by LED light, researchers managed to…

The dominant theory in neuroscience has been that the sensory processing circuits in our brain are finalized in early childhood and fixed afterward. A recently published study, however, overturned this ...

Researchers found that cutting two amino acids common in animal protein—methionine and cysteine—made mice burn significantly more energy. The boost in heat production was nearly as powerful as constant exposure to cold temperatures. The mice didn’t eat less…
