“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…

Scientists at MIT have found compelling chemical evidence that Earth’s earliest animals were likely ancient sea sponges. Hidden inside rocks over 541 million years old are rare molecular “fingerprints” that match compounds made by modern demosponges. After…

For decades, scientists believed a fertilized egg’s DNA began as a shapeless mass, only organizing itself once the embryo switched on its genes. But new research reveals that the genome is already carefully arranged in three dimensions long before that critical…

Heart disease is on track to tighten its grip on American women. New projections from the American Heart Association warn that over the next 25 years, cardiovascular disease will rise sharply, driven largely by a surge in high blood pressure, diabetes, and…

A sweeping scientific review highlights wild blueberries as a standout food for cardiometabolic health. The strongest evidence shows improvements in blood vessel function, with encouraging signs for blood pressure, cholesterol, blood sugar, gut health, and…

New research by engineers at the University of Colorado Boulder aims to get to the bottom of why, as the saying goes, you get a "skip in your step" when you're happy.

Gene therapy has been successfully used to treat a number of diseases, including immune deficiencies, hereditary blindness, hemophilia and, recently, Huntington's disease, a fatal neurological disorder.
