Microplastics discovered in human reproductive fluids

The University of Minnesota is stepping up efforts to identify biological threats that could trigger an epidemic, launching an institute to track disease-spreading infectious pathogens at the genetic level and monitor wastewater statewide.

Capital Medical University, in collaboration with the Chinese Academy of Sciences, reports that betaine, a molecule produced in the kidney and enhanced through sustained exercise, operates as a potent inhibitor of inflammatory and aging-related pathways.

As part of its ongoing quest to redefine how people understand and address the brain's health and performance, the Center for BrainHealth at UT Dallas collaborated with the Camp Pendleton Intrepid Center on new research investigating the effects of cognitive rehabilitation protocols on the brain performance of active-duty service members (ADSMs) with mild traumatic brain injury (mTBI) and post-traumatic stress disorder (PTSD). Cognitive strength, resilience, agility and focus are essential to military readiness and overall well-being.

More people in the United States died by gun suicide in 2023 than any year on record—more than by gun homicide, accidental shootings and police shootings combined.

When ocrelizumab became the first FDA-approved treatment for early forms of multiple sclerosis (MS) in 2017, it offered patients immense hope. The long-awaited drug is a monoclonal antibody that depletes B cells—the immune cells that drive MS progression. Exactly how ocrelizumab does this, however, remains unclear.

A landmark 30-year study of over four million women in England has revealed that women with endometriosis-associated infertility are significantly more likely to become pregnant compared to those with infertility from other causes.

Since their discovery by Wilhelm Roentgen in 1895, X-rays have become a staple of modern medical care, from imaging teeth and broken bones to screening for the early signs of breast cancer.

A Texas mother of two, Brianna Henderson, was diagnosed with a rare and potentially fatal heart condition after having her second child. In addition to avoiding another pregnancy that could be life-threatening, Henderson has to make sure the contraception she uses doesn't jeopardize her health.

Tens of thousands of people suffer needless heart attacks and strokes every year because they aren't taking cholesterol-lowering drugs, a new study says.

University of Texas Southwestern Medical Center scientists found that activating fibroblast growth factor 21 (FGF21) exclusively in the fat tissue of adult male mice prolonged lifespan under sustained high-fat diet feeding, achieving extended life-spans without previously associated reductions in growth or bone density.

Scientists have revealed how certain immune cells may be quietly helping prostate cancer grow—and how blocking them could help the body fight back.

When a person starts to lose their balance on a slippery surface, the natural reaction is to raise the arms to restore balance. Adults aged 65 and older may move their arms more slowly when slipping, which could increase their risk of falling, according to a University of Arizona Health Sciences-led study.

There has been a lot of research focused on understanding women's experiences with depression during the menopause transition and early menopause, but there are few studies on perimenopausal women's experiences with emotional arousal, such as anger. A new study shows that women's anger traits significantly decrease with age starting at midlife.

A new study examining racial disparities in unmet pain treatment finds that patients suffering from acute pain whose opioid treatment preferences were not met during an emergency department visit are at elevated risk of misusing them three months later. This was particularly true for Black patients, who were likelier than whites to be sent home without an opioid prescription.

Gene therapy can improve hearing in children and adults with congenital deafness or severe hearing impairment, a new study involving researchers at Karolinska Institutet reports. Hearing improved in all 10 patients, and the treatment was well-tolerated.

A new AI model is much better than doctors at identifying patients likely to experience cardiac arrest. The linchpin is the system's ability to analyze long-underused heart imaging, alongside a full spectrum of medical records, to reveal previously hidden information about a patient's heart health.

Struggle with math? A gentle jolt to the brain might help.

Canada must address the growing crisis of communicable diseases that has occurred in tandem with a rise in misinformation that threatens our health systems, argue the authors in an editorial in the Canadian Medical Association Journal.
