DHEA-S hormone linked to shorter lifespan in men, but not women

A recent study published in the Open Access Journal of Sports Medicine reveals that hockey players' cognitive processing speeds vary by position—and that these abilities can be trained.

Appendix cancer is a condition that, until recently, was so rare that most people never gave it a second thought. For decades, it was the kind of disease that doctors might encounter only once or twice in a career, and it was almost always found in older adults.

Breathing—a natural and essential process—can be an incredibly labored process for people with cystic fibrosis. CF, a genetic disease that affects secreted fluids (mucus, sweat, digestive juices), causes problems throughout the body, but most CF patients have symptoms in the lungs.

Cornell researchers have discovered a new cell signaling pathway involved in ovulation, a potential target for future research on infertility, contraception and ovarian disease.

People who carry a bitter "supertaster gene" have been linked to various health conditions including bipolar disorder and poor kidney function, University of Queensland researchers have found.

"We tend to consume more than enough protein already," says Roger A. Fielding, senior scientist at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) and professor at the Friedman School of Nutrition Science and Policy.

Excess fat mass estimated by waist-circumference-to-height ratio predicts the risk of liver damage better than body mass index (BMI) estimated obesity, a new study shows. Waist-to-height ratio is a cheap and universally accessible tool to detect the risk of fatty liver disease both in the young and adult population.

Telehealth can make health care easier to access for patients with attention-deficit/hyperactivity disorder (ADHD) who need treatment, but experts worry about an increased risk of substance use disorder for patients being prescribed controlled medications such as stimulants for ADHD during these appointments.

Glioblastoma (GBM) is the most aggressive and lethal form of brain cancer, with a median survival of only 15 months despite intensive treatment. Current therapies—including surgery, radiation, and chemotherapy—offer limited long-term benefit, and immune-based treatments have so far shown minimal success. The complexity of the tumor's microenvironment and its ability to suppress immune responses contribute to the poor prognosis.

A medical research team at Saarland University, led by Professor Bergita Ganse, has discovered a new approach to monitoring bone fracture healing by measuring blood supply to the tissue at the fracture site and the level of oxygen in the blood. Bone regeneration can be monitored quickly and easily using near-infrared light rather than harmful shorter wavelength radiation.

Researchers at the University of California, Davis, have developed an investigational brain-computer interface that holds promise for restoring the voices of people who have lost the ability to speak due to neurological conditions.

New research indicates that children infected with COVID-19 may face increased cardiovascular disease risks indicated by blood plasma metabolic changes.

Scientists have discovered a unique class of small antibodies that are strongly protective against a wide range of SARS coronaviruses, including SARS-CoV-1 and numerous early and recent SARS-CoV-2 variants. The unique antibodies target an essential highly conserved site at the base of the virus's spike protein, effectively clamping it shut and preventing the virus from infecting cells.

A recent study led by Judit Simon from the Department of Health Economics, Center for Public Health, at the Medical University of Vienna shows for the first time comprehensively the extent to which people with mental disorders suffer from physical illnesses—and the resulting hospital costs.

Diabetic weight-loss medications are effective for people with schizophrenia without affecting psychotic symptoms, University of Queensland researchers have found.

As more and more people spend time chatting with artificial intelligence (AI) chatbots such as ChatGPT, the topic of mental health has naturally emerged. Some people have positive experiences that make AI seem like a low-cost therapist.

A cluster of at least 10 botulism cases linked to Botox procedures at a spa outside Boston is raising concerns about the safety of the popular cosmetic procedure.

Infection control researchers at Mass General Brigham have developed a virtual reality (VR) tool to train clinicians on core concepts in infection control, including cleaning and disinfecting portable medical equipment, to prevent the spread of infections throughout health care facilities.
