Flu is rising rapidly across the U.S., driven by a new variant of the virus—and cases are expected to keep growing with holiday travel.

That variant, known as “subclade K,” led to early outbreaks in the United Kingdom, Japan and Canada. In the U.S., flu typically begins its winter march in December. On Tuesday, the Centers for Disease Control and Prevention reported high or very high levels of illness in more than half the states.

The CDC estimated there have been at least 7.5 million illnesses, 81,000 hospitalizations and 3,100 deaths from flu so far this season...

Singapore has one of the highest life expectancies in the world, yet many individuals spend almost a decade in poor health toward the end of life. Scientists from the Yong Loo Lin School of Medicine, National University of Singapore (NUS Medicine) are working to understand how aging itself can be modified to prevent age-related diseases, including Alzheimer’s disease.

A new study led by Professor Brian K Kennedy, Department of Biochemistry, Chair of the Healthy Longevity Translational Research Program (TRP), NUS Medicine, has discovered that calcium alpha-ketoglutarate (CaAKG), a safe, naturally occurring metabolite commonly studied for healthy aging, can restore key memory...

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...
