Over 70 million Americans wear digital activity trackers (DATs) to record their sleep, steps and heart rate. A new study from Scripps Research found that these devices could also provide insight into even more, including individual health risks like obstructive sleep apnea (OSA) and high blood pressure.

The findings, published in the Journal of Medical Internet Research on December 3, 2025, used DATs to identify an association between sleep variability—the night-to-night fluctuation of when an individual falls asleep and wakes—and their risk of developing sleep apnea and hypertension. This research joins a growing body of evidence that DATs could become more useful clinical tools to assess health risks in the near future.

“Data from digital activity trackers provides a uniqu...

A humble Brazilian coastal plant used in folk medicine is now backed by science as a potential natural fighter against inflammation and arthritis.

A research team in Brazil has found strong evidence that the Joseph’s Coat plant (Alternanthera littoralis) is both safe and effective at reducing inflammation, easing pain, and protecting against arthritis. The study was carried out by scientists from the Federal University of Grande Dourados (UFGD), the State University of Campinas (UNICAMP), and São Paulo State University (UNESP).

Joseph’s Coat grows naturally along Brazil’s coastline and has long been used in tradi...

Researchers have developed experimental drugs that encourage the mitochondria in our cells to work a little harder and burn more calories. The findings could open the door to new treatments for obesity and improve metabolic health.

Obesity is a global epidemic and a risk factor for many diseases, including diabetes and cancer. Current obesity drugs require injections and can cause side effects, so a safe way to boost weight loss could deliver significant public health benefits.

The study, led by Associate Professor Tristan Rawling from the University of Technology Sydney (UTS), has just been published in Chemical Science, where it was highlighted as “pick of the week.”

Temporal lobe epilepsy, which results in recurring seizures and cognitive dysfunction, is associated with premature aging of brain cells.

A new study by researchers at Georgetown University Medical Center found that this form of epilepsy can be treated in mice by either genetically or pharmaceutically eradicating the aging cells, thereby improving memory and reducing seizures as well as protecting some animals from developing epilepsy.

The study appears in the journal Annals of Neurology.

Current challenges and hopes for treatment
“A third of individuals living with epilepsy don’t achieve freedom from seizures with current medications,” says senior author Patrick A. Forcelli, Ph.D...
