A new study of COVID-19 shutdowns in the United States reveals pronounced disparities in air pollution -- with disenfranchised, minority neighborhoods still experiencing more exposure to a harmful air pollutant compared to wealthier, white communities.
Monster wildfire tests years of forest management efforts
Ecologists in a vast region of wetlands and forest in remote Oregon have spent the past decade thinning young trees and using planned fires to try to restore the thick stands of ponderosa to a less fire-prone state.
Research shows microbes play critical role boosting vigor of hybrid corn
A new paper appearing the Proceedings of the National Academy of Sciences gives new detail and understanding to the cultivation of corn, one of the United States' biggest cash crops.
Signs of life on Mars? Perseverance rover begins the hunt
NASA's Mars 2020 Perseverance rover has begun its search for signs of ancient life on the Red Planet. Flexing its 7-foot (2-meter) mechanical arm, the rover is testing the sensitive detectors it carries, capturing their first science readings. Along with analyzing rocks using X-rays and ultraviolet light, the six-wheeled scientist will zoom in for closeups of tiny segments of rock surfaces that...
Researchers develop novel method for glucagon delivery
For children with Type 1 diabetes, the risk of experiencing a severe hypoglycemic episode is especially common—and for parents, the threat of that happening in the middle of the night is especially frightening. Sudden and critical drops in blood sugar can go undetected overnight when the child is asleep, resulting in coma and death—an event known as "dead in bed syndrome."
COVID-19 shutdowns reveal racial disparities in exposure to air pollution
A new study of COVID-19 shutdowns in the United States reveals pronounced disparities in air pollution—with disenfranchised, minority neighborhoods still experiencing more exposure to a harmful air pollutant compared to wealthier, white communities. This first-of-a-kind study published today by researchers at the George Washington University looks at how air pollution changed after schools and...
