The brain navigates new spaces by 'flickering' between reality and old mental maps, say scientists

The most common first diagnosis of Alport syndrome in Japan is during the universal age-3 urine screening. In 60% of these children, the disease had already progressed far enough to qualify for treatment. Therefore, universal early-age urinalysis may be an apt means for both better prognoses and reduced costs of medical care.

Engineering and health researchers at the University of Waterloo have developed a radar and artificial intelligence (AI) system that can monitor multiple people walking in busy hospitals and long-term care facilities to identify possible health issues.

The genetic roots of a disease or disorder do not always grow into clear-cut, easily diagnosed clinical features. Even if a parent and child have the same genetic marker implicated in an outcome, such as autism, only one may present clinically or they may both present with wildly different features.

Social hierarchies are everywhere—think of high school dramas, where the athletes are portrayed as the most popular, or large companies, where the CEO makes the important decisions. Such hierarchies aren't just limited to humans, but span the animal kingdom, with dominant individuals getting faster food access, higher mating priority, and bigger or better territories. While it's long been thought that winning or losing can influence the position of an individual within a social hierarchy, the brain mechanisms behind these social dynamics have remained a mystery.

A study by Dorothy P. Schafer, Ph.D., and Travis E. Faust, Ph.D., at UMass Chan Medical School, explains how two different cell types in the brain—astrocytes and microglia—communicate in response to changes in sensory input to remodel synapses, the connections between neurons.

For the first time, the OHCAO team at University of Warwick have published national data for children who suffer out-of-hospital cardiac arrest, underscoring the urgent need for CPR training.

Scientists at City of Hope have uncovered a gene called SMOC1 that plays a surprising role in the development of type 2 diabetes (T2D) by converting pancreatic cells that normally produce insulin into those that increase blood sugar.

Quinn Cochran-Zipp went to the emergency room three times with severe abdominal pain before doctors figured out she had early-stage cancer in the germ cells of her right ovary. After emergency surgery four years ago, the Greeley, Colorado, lab technician is cancer-free.

A study finds that a representative sample of people given wearable data collection devices provides more equitable and accurate health data than larger convenience samples of people who already own wearable devices. Leveraging the smartwatches and other data-logging wearables that people already have is a tempting way to gather data, but such groups overrepresent the wealthy, urban, white, and fit people who tend to buy these products.

Pegasus slowly trots out of an elevator, surrounded by doctors and nurses. He's ready to make his rounds and see the many sick children hospitalized at Holtz Children's Hospital, located on Jackson Memorial Hospital's Miami campus.

A Curtin University-led study has identified the most critical risk factors linked to neonatal deaths worldwide, providing comprehensive evidence to help guide global efforts to save newborn lives.

Raising a child is never easy, and for many parents, the journey is made even harder by the quiet weight of mental health struggles. New research shows that mental health conditions often affect both partners—and can deeply influence their children's well-being.

New research presented at UEG Week 2025 shows that microplastics—plastic particles smaller than 5 mm commonly found in the environment—can alter the human gut microbiome, with some changes resembling patterns linked to depression and colorectal cancer.

New research finds that "man's best friend" may help slow biological aging in women. This groundbreaking study, focused on female veterans in the United States, is among the first to examine the impact of working with service dogs on this often-overlooked population. By measuring biological indicators of stress, the researchers have uncovered a key insight: the way stress is felt emotionally doesn't always reflect how it affects the body at a cellular level.

Why the End of Life Option Act had an expiration date is thanks to a near-extinct political impulse: compromise. Opponents feared that vulnerable people would be pushed towards death, exterminated for being too troublesome or expensive.

Robust performance under uncertainty, valid reasoning grounded in evidence, and alignment with real clinical need are prerequisites for trust in any health care setting.

A noninvasive device that delivers weak electrical currents to the brain may help those with multiple sclerosis cut back on excessive cannabis use, a new NYU Langone Health study of women with the condition shows.

Scientists have reversed diabetic heart failure with a genetic therapy in mice and miniature human "hearts" grown from stem cells. The new gene therapy may be a promising treatment for diabetic heart disease, in which the heart can't relax properly between beats.
