Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary fin
Greenland sharks may live for 400 years without suffering the kind of retinal decline normally associated with aging. Researchers found healthy eye tissue and active proteins specially adapted for see
Mice that developed compulsive drinking after alcohol abstinence showed more than double the activity in a brain region associated with stress and addiction. Because the signal appeared before they dr
Peppermint oil may have an unexpected benefit for people with mildly high blood pressure. Adults who took a small dose twice daily for 20 days saw their systolic blood pressure fall by an average of 8
Exercise may not be a powerful weight-loss tool on its own, but it appears to play a much bigger role in preventing lost weight from returning. By preserving muscle, supporting metabolism, improving f
People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier an
A simple yeast-based food supplement may help restore the immune system’s ability to fight cancer, according to new research in mice. Scientists found that yeast beta-glucan reprogrammed early immune
Pancreatic cancer patients with at least 21 natural teeth survived nearly two years longer after surgery than those with fewer teeth in a study of 339 people. Researchers suspect tooth loss may reflec
Scientists have linked a specific gut bacterium, Roseburia inulinivorans, to stronger muscles in both humans and mice. Older adults who carried it had 29% greater handgrip strength, while treated mice
NPR's David Folkenflik talks with Don Schaffner, a food microbiology specialist and distinguished professor at Rutgers University, about this summer's foodborne illnesses and recalls.
A few minutes of sprinting may reshape the bloodstream far more dramatically than a much longer moderate workout. Six 30-second sprints altered nearly a quarter of the blood proteins measured and more
A hormone already known for curbing appetite and supporting weight loss may have a surprising second job: protecting the liver from inflammation and scarring. Researchers at McMaster University found
AI may be able to predict how strongly someone will respond to a vaccine before they receive it. By analyzing antibody patterns in more than 4,000 people, researchers found signs of “immune readiness”
The USS Abraham Lincoln – which has been participating in U.S. military operations in the war with Iran – is now on its way home. The roughly 5,000 sailors and marines aboard that ship have spent nine

People who participated in colorectal cancer screening had a 43% lower risk of dying from the disease, according to long-term data from more than 376,000 people in Sweden. The findings suggest that co
A compound made when gut bacteria break down dietary fiber may do more than briefly calm inflammation—it could leave a lasting protective “memory” in the gut. Northwestern Medicine researchers found t
Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could rev
