University of Maryland School of Medicine’s Institute of Human Virology contributes to Global Virus Network studies suggesting that the oral polio vaccine can protect people in developing nations that do not yet have access to COVID vaccines
A team of NYU Tandon researchers investigated whether mortality prediction models vary significantly when applied to hospitals or geographies different from the ones in which they are developed. With electronic health records from 179 hospitals across the U.S. with 70,126 hospitalizations from 2014 to 2015 — they investigated whether data could explain variations in clinical performance based on factors like race.

Feeling unhappy? Go find a park—the bigger the better—and try taking a walk outdoors. That’s the takeaway of a major new study measuring the happiness effects of city parks in the 25 largest U.S. cities. The happiness benefit of urban nature on users was akin to the mood spike people experience on holidays like Thanksgiving or New Year’s Day. The research is the largest study of its kind—using massive amounts of data from social media—to quantify the mood boosting benefits on urban nature. The happiest place on Twitter? The great outdoors. The study will appear March 30 at 2 pm EST in PLOS One journal.
