That college degree may be useful in many ways, but new research suggests it probably won’t keep your brain from shrinking with age. Over the years, a number of studies have suggested that education might buffer people against age-related declines in memory and thinking. But those findings did not prove a cause-and-effect relationship. In the…  read on >  read on >

In rare cases, people hospitalized for COVID-19 can develop heart failure, even if their hearts were previously healthy, new research shows. The researchers found that of over 6,400 COVID-19 patients at their hospital, 0.6% newly developed heart failure. That included eight patients — mostly relatively young men — with no history of heart disease or…  read on >  read on >

A strong immune response to the virus that causes COVID-19 by the placenta may help explain why infected pregnant women face a higher risk of complications, such as preterm birth and preeclampsia, researchers say. The Yale University team analyzed blood and placental tissue from 39 women at different stages of pregnancy. They detected evidence of…  read on >  read on >

The risk of mother-to-newborn transmission of COVID-19 is low, but the illness in pregnant women can trigger preterm birth, researchers say. The new study looked at 255 babies born in Massachusetts last year to mothers with a recent positive test for COVID-19. Only about 2% of the 88% of babies who were tested for COVID-19…  read on >  read on >

Not even your beloved feline is safe from COVID-19. Using in-depth genetic analyses, a new investigation in the United Kingdom suggests that people can pass COVID-19 on to their cats. “We identified two cats that tested positive,” said study lead author Margaret Hosie. “Both of them were from suspected COVID-19 households.” One case involved a…  read on >  read on >
