The everchanging social, political, and economic landscape in many countries has become more tenuous and intense in recent years.

A study of preschool children found that brief digital or traditional gameplay improved performance on tasks requiring quick responses, but reduced performance on tasks demanding greater concentration and self-control.

Mitochondria are popularly known as the "powerhouse of the cell," but these cellular structures do so much more-including acting as signaling hubs.

Conventional wisdom holds that younger brains are better equipped to recover from injury. Their greater flexibility allows them to adapt, rebuild connections and compensate for damage in ways older brains often cannot.

The body's heart muscle (for pumping blood), skeletal muscle (for movement and posture), and brown fat (for heat production), each require a lot of energy and make a lot of waste. And that waste needs to be managed.

More than 56 million U.S. adults feed wild birds. For many, filling a feeder is a routine way to connect with birds and other wildlife. But researchers know less about what that interaction may mean for the people doing it.

Different autoimmune diseases often share genetic risk factors, but not through a single common genetic vulnerability.

Autophagy is an intracellular degradation mechanism in eukaryotes. The autophagosome, which encloses damaged or excess cellular material for degradation, is constructed from lipids supplied by the endoplasmic reticulum (ER), via the lipid transfer protein Atg2.

Researchers have identified a link between specific activities in gut bacteria and the liver disease PSC.

Albert Arias, MD, chief of addiction psychiatry at Carilion Clinic, has received an award from the National Institute on Drug Abuse (NIDA) to research how psilocybin, a psychedelic compound being studied for several psychiatric and substance use disorders, can offer a new approach for people with cocaine use disorder.

Pop-up messages that warn of the harms of social media - such as mental health consequences - have potential to reduce young people's social media use, a new Stanford Medicine study has found.

Medicaid has a reputation for paying doctors less than other health insurers. But exactly how much less has been difficult to establish, particularly for the vast majority of Medicaid patients whose care is provided through private health plans.

Researchers at the University of Oslo and Oslo University Hospital have, together with international collaborators, discovered that a small molecule made exclusively by gut bacteria can actively drive disease in the bile ducts and worsen primary sclerosing cholangitis (PSC), a serious liver and bile duct disease.

A lab-grown micro bladder may explain why urinary tract infections (UTIs) return so frequently, according to a study led by researchers at UCL, the University of Oxford and the University of Leicester.

For decades, natural killer (NK) cells have been classified into two main groups based on surface markers: one specialized for cytokine production and the other for direct killing.

Although the number of US children under age 12 with obesity being prescribed the weight loss drugs Saxenda, Wegovy, and Zepbound remains low, the number is 310 times higher in June 2026 than it was in 2019, when the drugs were initially prescribed, a new study shows.

As aging populations drive rising global healthcare demands, finding scalable ways to prevent cognitive decline has become a vital public health priority.

As the human brain takes shape before birth, a remarkable type of stem cell helps give it many of the features that make it distinctly human.

Some of Europe's most well-known historic manuscripts, including the York Gospels, have proven to be biological time capsules for uncovering the 3,500-year history of the sheeppox virus (SPPV).

A marathon, 100 kilometers or even 230 kilometers in one go: Anyone running such distances puts enormous strain on their body.
