In the early days of the pandemic, doctors noticed something about the people severely ill from COVID-19: Many were obese. The link became more apparent as coronavirus swept across the globe and data mounted, and researchers are still trying to figure out why. Full coverage of the coronavirus outbreak Excess weight increases the chances of developing a number of health problems, including heart disease and diabetes. And those are among the conditions that can make COVID-19 patients more likely to get very sick. But there's some evidence that obesity itself can increase the likelihood of serious complications from a coronavirus infection. One study of more than 5,200 infected people, including 35 percent who were obese, found that the chances of hospitalization rose for people with...

Skin fibroblasts were successfully reprogrammed into the smooth muscle cells (red) and endothelial cells (white) which surround blood vessels. The cells’ nuclei are shown in blue. Credit: Bersini, Schulte et al. CC by 4.0 Salk study is the first to reveal ways cells from the human circulatory system change with age and age-related diseases. Salk scientists have used skin cells called fibroblasts from young and old patients to successfully create blood vessels cells that retain their molecular markers of age. The team’s approach, described in the journal eLife on September 8, 2020, revealed clues as to why blood vessels tend to become leaky and hardened with aging, and lets researchers identify new molecular targets to potentially slow aging in vascular cells. “The vasculature is...

COLUMBUS, Ohio — Popping a Tylenol for that nagging headache may do more than just provide some pain relief. A new study finds that taking acetaminophen may also cause an individual to take greater risks than they would otherwise. Researchers at The Ohio State University conducted a series of experiments to see how the popular pain reliever affects decision making. While we often hear warnings about how acetaminophen can affect the liver, this latest side effect may give thrill-seekers reason to pause. In one experiment, researchers had 189 college students take 1,000 mg of acetaminophen, the suggested dosage for a headache. Some students were unknowingly given a placebo instead of the drug. Once the medication kicked in, participants were given a list of various events and then rated...

Fears have arisen that bubonic plague could spread into China after its bordering country Mongolia reports its third victim who died of the Black Death this year. A 38-year-old man had died from the plague on Monday in Mongolia's western Zavkhan province after eating marmot meat last month, said the local authorities. It comes as China's Inner Mongolia region, near the Chinese border with Mongolia, has recorded two deaths caused by the plague in August, prompting the authorities to impose partial lockdowns and quarantine residents. Fears have arisen that bubonic plague could spread into China after its bordering country Mongolia reports its third victim who died of the Black Death this year. This picture taken on September 4 shows a man walking with the Chinese nation...
