A new study offers insight into the health and lifestyle indicators—including diet, physical activity and weight—that align most closely with healthy brain function across the lifespan. The study used machine learning to determine which variables best predicted a person’s ability to quickly complete a task without becoming distracted.

It’s been long established that our working memory, which allows us to temporarily hold and use information, such as remembering a phone number or a shopping list, is largely driven by the brain’s prefrontal cortex. However, new research finds that the part of the brain used in visual processing plays a much more critical role in working memory than previously thought.

Washington state reported 25 times as many whooping cough cases last year as the year before, according to new data that serve as a reminder of the disease’s continued surge here and nationwide.

Living in zero gravity can lead to periodontitis, a common and serious condition where the gums become inflamed and the bone that supports teeth starts to break down, eventually leading to tooth loss, scientists reveal in a new study.

When the brain is under pressure, certain neural signals begin to move in sync—much like a well-rehearsed orchestra. A new study from Johannes Gutenberg University Mainz (JGU) is the first to show how flexibly this neural synchrony adjusts to different situations and that this dynamic coordination is closely linked to cognitive abilities.

Esther Bejarano’s son was 11 months old when asthma landed him in the hospital. She didn’t know what had triggered his symptoms—neither she nor her husband had asthma—but she suspected it was the pesticides sprayed on the agricultural fields near her family’s home.

Stony Brook University-led researchers tracked post-traumatic stress disorder symptoms in more than 12,000 World Trade Center responders for 20 years and found that recovery was often delayed, non-linear and incomplete.

Rest, rehab and patience are cornerstones of injury recovery. But should quitting alcohol be a part of any recovery plan? This is what England cricket captain Ben Stokes has done—saying he’s given up alcohol in a bid to quickly recover from a serious hamstring injury.

At some point in their lifetimes, approximately one out of every eight women in the United States will be diagnosed with breast cancer. That estimate from the American Cancer Society becomes even more troubling when considering that the rate of breast cancer incidence continues to climb, rising around 1% every year from 2012–2021.

Exercising is healthy, but it also puts strain on the heart. During physical exertion, the protein troponin is released—a biomarker indicative of cardiac damage. New research from Radboudumc involving a thousand athletes shows that elevated troponin levels after exercise are not due to coronary atherosclerosis. This suggests that the cause of elevated troponin levels after exertion lies elsewhere.
