As families get ready for outdoor summer adventures, a Simon Fraser University study has found that alcohol significantly reduces the chance of youths being rescued from drowning. The findings indicate that teenagers are nearly eight times more likely than infants to drown without any rescue attempt, while the presence of alcohol quadruples the chance of no rescue attempt.

The U.S. Food and Drug Administration (FDA) has cleared the first over-the-counter wearable device to track blood sugar in young children.

Parents who find time for themselves feel better and show healthier physiological stress patterns on the same day, according to my new research. The findings suggest that even small moments away from daily demands may help mothers and fathers recharge emotionally and physically.

Female patients with kidney failure are significantly less likely to be referred to a transplant center for assessment, according to a new study from ICES, London Health Sciences Center Research Institute (LHSCRI) and Western University. The disadvantage widened with increasing age. The findings were published in the May issue of the Canadian Journal of Kidney Health and Disease.

Is the time teenagers spend on social media really damaging their well-being and mental health? Around the globe, youth mental health problems are on the rise. This has coincided with an ever-increasing amount of time teenagers spend on platforms such as TikTok, Instagram, X and Snapchat.

Nearly one in three adults in Denmark score high on the stress scale, and more than one in 10 feel lonely. This is shown by the large survey The National Health Profile 2025. There is good reason to pay attention to the mental health of the Danish population—and now researchers, municipalities and others working with well-being and mental health promotion have a new tool at their disposal.

The U.S. Food and Drug Administration (FDA) is investigating a multistate outbreak of infant botulism linked to Nara Organics Whole Milk Organic Powdered Infant Formula.

A new study from the German Institute of Human Nutrition Potsdam–Rehbruecke (DIfE) and Charité—Universitätsmedizin Berlin shows for the first time that targeted control of human breathing rhythm can influence decision behavior by modulating heart and brain function. The research team led by Prof. Soyoung Q. Park was able to demonstrate that prolonged exhalation increases heart rate variability and the brain’s reward sensitivity, thus enabling us to make bolder decisions. The study was published in the journal Neuron.

The largest-ever U.K. trial of a urine test used across the NHS to spot when patients skip their medication has shown it may improve adherence to treatment. Led by researchers at the University of Manchester and Manchester University NHS Foundation Trust (MFT), the study investigated the efficacy of a urine test that detects the presence or absence of blood pressure-lowering medications—known as chemical adherence testing, or CAT.

Soccer is faster and more physically demanding than ever—and injuries are one of the biggest challenges facing the modern game. Muscle strains, ligament damage and long-term rehabilitation can affect team performance, player welfare and club finances. As the FIFA World Cup 2026 gets underway, Professor Ian Varley—an expert in soccer injury surveillance at Nottingham Trent University—explains why injuries happen, which are most common and how science is reducing the risk.

A study led by scientists from the A*STAR Genome Institute of Singapore (A*STAR GIS) has uncovered how the gut microbiome can influence gene activity in the liver by acting on short stretches of regulatory DNA that function like molecular “switches.” By testing the activity of more than 100,000 human DNA switches linked to liver biology and comparing results from both in vitro and in vivo approaches, the team identified which switches operate under real physiological conditions and how microbial signals can modify their activity. This provides a clearer biological basis for how gut microbes shape liver function, offering new avenues for precision diagnostics and targeted therapies for liver disease. The findings were published in Molecular Cell.

A human brain network associated with survival in children with diffuse midline glioma (DMG), the deadliest childhood brain cancer, has been identified by UCL clinician-scientists, raising the possibility of entirely new treatment approaches. The researchers found that DMG tumors seem to exploit the brain’s existing neural circuitry to drive tumor growth and progression. Tumors that were more strongly connected to this network were associated with significantly shorter patient survival.

The Trump administration has issued final rules on how states should ensure that millions of Medicaid enrollees prove they’re working or completing other activities, such as job training, volunteering or being enrolled in an educational program.

A research group led by Dr. Keiko Ueno, assistant professor at the Innovative Clinical Research Center, Kanazawa University, has revealed the status of collaboration between fire-based emergency medical service (EMS) agencies and community-based long-term care, welfare , and health organizations in Japan. The study identified six key practical measures essential for building a collaborative model that sustains long-term coordination between medical care and social support needs.

In the largest genetic study of inflammatory bowel disease (IBD) traits to date, researchers have identified a genetic marker associated with more severe ulcerative colitis and Crohn’s disease—the major forms of IBD.

Alzheimer’s-Related Psychosis: Interdisciplinary Perspectives for Understanding and Responding to Delusions and Hallucinations”—the latest report in The Gerontological Society of America’s Insights & Implications in Gerontology series—underscores the clinical, emotional and societal impact of psychosis in individuals living with Alzheimer’s disease and stresses the need for comprehensive, person-centered approaches to care.

Every time we move through a familiar environment, the hippocampus consults an internal map, a detailed spatial representation built up through repeated experience. But what happens when something unexpected occurs on a well-known route? Researchers at the University Hospital Bonn (UKB) and the University of Bonn demonstrated in a mouse model that the brain does not redraw its maps from scratch. Instead, it annotates them, preserving the underlying spatial layout while overlaying new information on top of the existing map. The paper is published in the Proceedings of the National Academy of Sciences.

ALS (amyotrophic lateral sclerosis) is a fatal neurodegenerative disease that gradually affects a person’s ability to move, speak and breathe. It advances differently in every patient. Now, researchers at Nagoya University have developed an AI tool that uses data from patient follow-up studies to estimate the speed of disease progression and identify patterns of muscle decline. The study is published in npj Digital Medicine.

Screening people with the rare, inherited cancer-causing condition Li-Fraumeni syndrome (LFS) brings both medical and economic benefits to patients and health care systems, according to research to be presented to the annual conference of the European Society of Human Genetics.

Understanding why some people stay healthy without developing disease until late in life (have an increased healthspan), whereas others become infirm at a much younger age, has important implications for the health of today’s aging population. Life expectancy has significantly increased in the last two centuries, but healthspan has not kept pace.
