EPFL scientists have shown that a gene linked to a rare childhood disease is essential for regenerating intestinal stem cells after injury.

A recent study by the University of Eastern Finland is the first to report that the fatty acid composition of blood and the enzyme activity associated with it predict the development of bone mineral density from childhood to adolescence. The results of the Physical Activity and Nutrition in Children (PANIC) study were published in the Journal of Bone and Mineral Research.

US Health Secretary Robert F. Kennedy Jr. on Tuesday unveiled the Trump administration's long-awaited plan to tackle chronic disease, calling for better nutrition, tighter scrutiny of medical advertising, and even a new push to boost fertility.

In Finland, the proportion of births among women aged over 35 has increased, in 2024 accounting for 27.7% of all births. This trend has important implications both at the societal level and for individuals.

For adults with a history of smoking undergoing low-dose computed tomography (LDCT) for lung cancer screening, emphysema is predictive of mortality up to 25 years, according to a study published online Sept. 9 in Radiology.

A global research consortium of over 100 study groups in more than 65 countries has launched the Global RETFound initiative, a collaborative effort to develop the first globally representative Artificial Intelligence (AI) foundation model in medicine, using 100 million eye images.

New research by Wistar Institute scientists shows how targeting a cleft in the retinoblastoma protein can kill tumor-protecting macrophages in ovarian cancer. The discovery provides a novel therapeutic target that could potentially make ovarian and other cancers more sensitive to immunotherapies. Their findings are published in Cancer Immunology Research.

A new longitudinal study led by York University's Department of Psychology published today finds that young adults experiencing periods of high stress, anxiety and depressed mood more frequently combined binge drinking with cannabis use in order to get more high and drunk, and were also likely to report more adverse life consequences when combining these substances. Lead author Jeffrey Wardell, Associate Professor in York University's Faculty of Health, says that since cannabis use among young adults has increased after Canada legalized the drug, understanding why people combine the drug and outcomes when they do is important.

Despite the promise of telehealth to bridge rural health care gaps, a new study published in the Journal of Medical Internet Research reveals that many rural-dwelling patients in the United States—especially those who are older, speak Spanish, or rely on public insurance—are still struggling to access virtual care.

Psychiatrists and mental health professionals have always relied on medication and talk therapy to treat depression, but Dr. Nicholas Fabiano, a psychiatry resident at the University of Ottawa, thinks it's time for a shift.

Lung cancer patients who take medications called GLP-1 receptor agonists—commonly prescribed for weight loss and diabetes management—fare better than those who don't, according to research led by Sai Yendamuri, MD, MBA, FACS, Chair of Thoracic Surgery at Roswell Park Comprehensive Cancer Center, and Joseph Barbi, Ph.D., Assistant Professor, Department of Immunology. Results of the study, which involved investigators from both Roswell Park and the Columbia University Irving Medical Center, appear in JCI Insight.

It's a well-known fact that fetal alcohol spectrum disorder (FASD) in children is caused by mothers who drink during pregnancy. But it turns out that the father's drinking habits could also affect a child's growth and development.

In a move that could reshape drug discovery, researchers at Harvard Medical School have designed an artificial intelligence model capable of identifying treatments that reverse disease states in cells.

Diet doesn't just fuel the body, it sends molecular signals that can slow down or speed up biological aging, according to a new perspective in npj Aging. The authors explain that biological age, a measure of functional health, can diverge sharply from chronological age and that targeted nutritional and lifestyle choices can bend the trajectory toward healthier aging.

A person will have Alzheimer's years before ever knowing it. The disorienting erasure of memories, language, thoughts—in essence, all that makes up one's unique sense of self—is the final act of this enigmatic disease that spends decades disrupting vital processes and dismantling the brain's delicate structure.

Lateralization of the brain—the tendency for the left and right hemispheres to specialize in different functions—underlies the development of a left-to-right mental number line, according to a study in newborn chicks.
