Blue, green, brown, or something in between—the science of eye color explained

When doctors prescribe oxybutynin, it's usually for an unglamorous problem: bladder incontinence. But researchers have discovered a surprising new role for this decades-old drug—one that could open the door to treatments for a devastating class of genetic illnesses known as mitochondrial diseases.

Improved pay for NHS staff is important to prevent high numbers leaving the service, according to new data from UCL and University of Leicester researchers.

Scientists from the Center for Medicinal Cannabis Research (CMCR) at the University of California San Diego School of Medicine found that, in the largest such study to date, frequent cannabis users did not display impairments in driving performance after at least 48 hours of abstinence. The new findings have implications for public health as well as the enforcement of laws related to cannabis and driving.

Mitochondria act as energy factories in cells and have their own, separate DNA. Mutations to mitochondrial DNA (mtDNA) have been observed in cancer, but it has been unclear how these changes might affect cancer growth.

Researchers from Keele University have revealed that retired Olympic athletes are more likely to develop skin cancer and osteoarthritis than the general population.

A study published in The New England Journal of Medicine finds that individuals who received medication for opioid use disorder (MOUD) while incarcerated were significantly more likely to continue treatment six months after release than those who did not receive MOUD.

Researchers at the University of Oulu's Research Unit of Clinical Medicine and Oulu Business School have examined how symptoms of adolescent ADHD (attention-deficit/hyperactivity disorder) and oppositional defiant disorder (ODD) are related to adult income.

The concept of the midlife crisis is part of the common lexicon. But did you know it was thought to occur at around age 35?

While vaccines can be very effective for preventing viruses, like the influenza A virus (IAV), they are often strain-specific and prone to viral escape mutations. IAV alone is responsible for around 500,000 deaths worldwide each year. To better serve vulnerable populations and prevent pandemic conditions, scientists have been searching for ways to create better, more universal, mutation-resistant, off-the-shelf IAV therapeutics.

Rapid scientific advances are accelerating the development of medical innovations, from personalized treatments to curative gene therapies and advanced diagnostic tools. But significant policy and regulatory reforms at the Food and Drug Administration are needed to fully harness the game-changing potential of these technologies, according to a new white paper from the USC Schaeffer Center for Health Policy & Economics.

A study from The University of Texas at San Antonio Health Science Center indicates that changes in the body that lead to type 2 diabetes occur long before current diagnostic thresholds for prediabetes are met.

For women who've overcome cervical cancer, new research from MUSC Hollings Cancer Center points to another health risk that may not be on their radar: anal cancer.

"Magic mushroom" edibles sold at smoke shops and convenience stores are likely to contain no psilocybin but instead a range of undisclosed active ingredients, a study led by an Oregon State University College of Pharmacy scientist shows.

If you've been supermarket shopping lately, you might have noticed more foods with big, bold protein claims on black packaging—from powders and bars to yogurt, bread and even coffee.

The government plans to redirect some children off the National Disability Insurance Scheme (NDIS) and onto a new program called Thriving Kids. When announcing the change last month, health and disability minister Mark Butler explained:

It might seem like a harmless habit to linger on the loo with your phone while "taking care of business," but research shows that prolonged toilet time can increase the risk of several health problems. Here are the main ones.

New research from the University of Sydney's Charles Perkins Center has found that genes play an active role in shaping the bacteria found in our gut, questioning the idea that gut health is influenced only by diet.

Accurate laboratory results are essential for clinical decisions—but every measurement carries some uncertainty.
