France's Pasteur Institute said it has fully sequenced the Andes virus detected in a French passenger from the MV Hondius cruise ship and found that it matched viruses already known in South America, with no evidence so far of new characteristics that would make it more transmissible or more dangerous.

A protein best known for driving cancer growth also helps damaged tumor cells survive by repairing their DNA, according to a new study that could influence how some cancers are treated.

Starting middle school brings big changes—new schools, heavier workloads, shifting friendships. These changes are easy for parents to see. But alongside them, something less visible may be happening: a rise in anxiety linked to puberty. In a new study led by FIU psychology postdoctoral associate Amanda Baker and published in Research on Child and Adolescent Psychopathology, researchers found that as children move through puberty, they report increasing anxiety while parents' perceptions of their child's anxiety remain relatively unchanged.

Severe childhood malaria is linked to long-term cognitive impairment, according to a new study from Indiana University School of Medicine researchers and their collaborators at Makerere University in Uganda. The findings, recently published in JAMA, suggest children who survive cases of cerebral malaria and severe malarial anemia experience cognitive and academic impairment that persists into adolescence. The correlation highlights an urgent need for the development of better prevention strategies and more effective therapies to minimize the lasting effects of one of the world's most dangerous diseases.

The survival rates of patients with esophageal and gastric cancers have improved. However, many survivors continue to experience long-term symptoms. On May 29, Kenneth Färnqvist will defend his thesis "The architecture of survivorship: patterns of quality of life, symptom dynamics, and self-care in esophageal and gastric cancer" in which he has investigated how quality of life, symptoms, and self-care develop over time.

A blood test that detects tumor DNA circulating in the bloodstream may help select the most effective treatment options for cancer patients whose tumors have started to spread, according to one of the largest randomized controlled trials of its kind presented at the Congress of the European Society for Radiotherapy and Oncology (ESTRO 2026).

Every day, millions of Americans open a fitness app, glance at their step count, and may even feel a mild pang of guilt before closing it again. The problem with most health tracking technology is that it watches your activity, but it doesn't really know you. A research initiative out of Stanford University School of Medicine is betting that the difference between an app people ignore and one that actually changes behavior comes down to a simple idea: the right message, for the right person, at the right moment.

Peripheral artery disease (PAD) affects 8 to 12 million Americans. The condition is caused by the buildup of plaque (cholesterol and other substances) inside blood vessels, restricting blood flow to the legs and disproportionately impacts marginalized communities. A leading cause of limb amputation, PAD often goes undetected until patients experience complications, in part because diagnosis requires a visit to a specialized clinic for a time-consuming and cumbersome ankle-brachial index (ABI) test.

Scientists' discovery of a molecular "switch" that activates an energy-burning pathway in mice has the potential to lead to new treatments for bone disease. The study, published in Nature, sheds new light on brown fat. Unlike white fat, which stores energy, brown fat cells burn calories, producing heat as a byproduct. For years, it was believed this process relied on a single pathway. More recently, researchers discovered a parallel pathway, but how it became activated had remained a mystery.

As worsening air quality and wildfire events increasingly impact communities worldwide, a study recognized by the American College of Sports Medicine (ACSM) as a 2025 Paper of the Year is drawing attention to a growing but often overlooked threat to athletes and active individuals: the impact of air pollution on performance, health, and safety.
