Outfitting cells in "invisibility cloaks" could offer a novel approach to treating diabetes

Outfitting cells in "invisibility cloaks" may offer an easier, less damaging treatment pathway for people with diabetes undergoing cell therapy, according to researchers at Penn State.

Opening the black box of biological aging clocks

What do "epigenetic clocks" actually measure? These lab tests have become popular tools for studying biological aging, or how the body's cellular function changes at a faster or slower rate than expected.

A 30-year study found a surprising link between alcohol, survival and heart attack risk

In a 30-year study of 973 middle-aged Swedish male automotive workers, alcohol consumption was associated with lower all-cause mortality and longer estimated time to death, while beer consumption was linked to a higher likelihood of myocardial infarction. No significant association was found between alcohol consumption and stroke, and the authors cautioned that socioeconomic differences, self-reported intake, and other unmeasured factors may have influenced the findings.

Meat, stress and risk-taking: what 38 experiments reveal about masculinity threat

Experimental evidence suggests that masculinity threat can push some men toward health-risk behaviors, with the clearest and most consistent effects seen in meat-related food choices. Across 38 experiments, effects on stress, fitness, risk-taking, and relationships were mixed or limited, while individual beliefs about masculinity shaped how men responded.

Most Americans still believe outdated antibiotic guidance, study finds

"Always finish your antibiotics" is no longer considered medical best practice for all conditions.

Your sleep and stress may be connected in a more complicated way than expected

A seven-day intensive longitudinal study of 106 university students found little evidence that higher-than-usual daytime stress predicted poorer sleep that night. In contrast, better-than-usual subjective sleep was followed by lower perceived stress the next day, while objective sleep associations were generally weak and uncertain.

New study focuses on starving bacteria to prevent Lyme disease

Triggered by a near painless tick bite, Lyme disease causes severe pain and inflammation for more than 475,000 people in the U.S annually, according to the Centers for Disease Control.

Smokers lack awareness of smoking-related cardiovascular risks

An international study has found that despite two decades of global tobacco control efforts, the message still is not getting through to enough smokers that smoking and second-hand smoke cause heart attack and stroke.

Alzheimer's markers show crucial differences across diverse global populations

Established Alzheimer's markers are also detected in blood samples from Nigeria and Tanzania. But other proteins in the blood differ from those seen in a comparable group in Canada.

Interactive platform maps habitat design effects on astronaut wellbeing

In extreme environments, habitats are built for survival. Submarines, Antarctic bases, and post disaster dwellings are designed to prioritize health and safety.

Automated MRI system improves improves evaluation of experimental stroke therapies

Researchers from the Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI) at the Keck School of Medicine of USC have developed an automated system that uses MRI to measure brain tissue changes in animal models for large, multicenter studies of experimental stroke treatments.

Swimming sends wrist-worn heart rate monitors off track

Researchers created an open-access dataset comparing two wrist-worn heart rate monitors with a chest-strap reference during dry-land exercise and swimming. Both smartwatches performed substantially worse underwater, highlighting the challenges water poses to optical heart rate monitoring and providing a resource for future research on aquatic wearables.

Inhaled cannabis reduces premature heartbeats in habitual users

Habitual cannabis users experienced about 9% fewer premature heartbeats on days they inhaled cannabis compared with days they abstained, a counterintuitive finding that adds to the complex and evolving understanding of how cannabis affects the heart, new UC San Francisco-led research found.
