Male circumcision is made easier by a clever South African invention. We trained health care workers to use it

Researchers led by Aurore Perrault at Concordia University, Canada and Valeria Kebets at McGill University, Canada, have used a complex data-driven analysis to uncover relationships among multiple aspects of sleep and individual variation in health, cognition, and lifestyle.

Efforts to suppress or change a child's gender identity and sexuality are ineffective and cause long-term harm, according to new research.

For patients with vestibular schwannoma (VS), those with anxiety have more severe dizziness, according to a study published online Oct. 2 in JAMA Otolaryngology-Head & Neck Surgery.

A new treatment for a debilitating inflammatory condition which affects joints and skin has shown promising early results in an international clinical trial of more than 200 patients worldwide.

A pilot study published in the Journal of the American Geriatrics Society found that a prehabilitation program that combines physical therapy, nutrition, and mindset support in the weeks leading up to major elective surgery is feasible and has the potential to improve postoperative outcomes.

To better understand anxiety, a psychologist from the University of Kansas studied 90 teenage girls in sessions spanning three years, using wearable eye‐tracking glasses as the subjects gave a speech to two judges: one who responded positively and one who responded potentially negatively. In other words, one judge maintained a neutral facial expression, occasionally looked around the room, and shifted in their seat.

In lieu of animal experiments, researchers from the University of Rochester are using state-of-the-art microchips with human tissue to better understand how the brain operates under healthy conditions and is damaged through neurodegenerative diseases or conditions like sepsis.

Cognitive decline and anxiety in Parkinson's disease are often only recognized at a late stage, yet they can greatly impact people's lives. Research by Marit Ruitenberg focuses on new tests and methods to improve early identification of these symptoms.

More than three-quarters of U.S. counties and jurisdictions are experiencing declines in childhood vaccination rates, a trend that began in 2019, according to a September 2025 NBC News–Stanford University investigation. The report also found a "large swath" of the U.S. no longer has the "basic, ground-level immunity" needed to stop the spread of measles.

Understanding the interaction between immune cells and cancer cells has important implications for cancer immunotherapies, including checkpoint inhibitor drugs and cell-based therapies, as well as newer treatments like cancer vaccines.

Advanced Chemistry of Catalonia (IQAC) of the Spanish National Research Council (CSIC), an institution under the Ministry of Science, Innovation and Universities, has discovered that a small compound—a peptide made up of four amino acids called CAQK—has a significant neuroprotective effect in mouse models of traumatic brain injury.

Child welfare professionals work in a stressful environment. Seeing families at risk of having children removed from the home frequently results in occupational trauma, burnout and negative health outcomes. University of Kansas researchers have published a study showing an intervention they delivered to child welfare workers across the state reduced secondary traumatic stress and improved resilience, which can ease the strain on workers and lead to better family outcomes.

UT Southwestern Medical Center researchers have identified two distinct populations of cells known as antigen-presenting cancer-associated fibroblasts (apCAFs) that appear to support the survival and growth of malignant tumors. Their findings, reported in Cancer Cell, could one day lead to new therapies for notoriously hard-to-treat cancers, including pancreatic cancer and advanced colorectal cancer (CRC) that has spread throughout the abdomen, known as peritoneal metastasis.

A major cardiovascular risk factor is thickening of the heart walls (hypertrophy), which can result from high blood pressure—but is also linked to inherited diseases of the heart which can lead to sudden death.

A "genomic-first" approach to screening for rare genetic disorders—identifying specific genetic variants and then studying associated traits and symptoms—can identify these conditions earlier and more frequently than standard genetic testing driven by clinical symptoms, a Geisinger study found.

A new study based on the 2022 National Youth Tobacco Survey has uncovered a concerning gap in how health professionals support young people dealing with mental health challenges and tobacco use.

A supplement of ketones may be the magic bullet that allows patients using weight-loss drugs to avoid the potentially adverse side-effect of a shrinking heart and skeletal muscle, according to a University of Alberta study in the European Journal of Preventive Cardiology that "fine-tunes" the popular therapy to protect lean muscle while shedding the same amount of fat.

In a new online trend, people are scuttling, crawling, and bounding around on all fours while filming themselves—and their videos are getting a lot of attention. The practice is called quadrobics, and it's quite the spectacle.
