Researchers have found that NASA’s PACE satellite can detect nitrogen dioxide pollution with enough precision to isolate emissions from individual factories and highway corridors.This new level of detail turns widespread atmospheric haze into a traceable source and reshapes the way pollution is identified, managed, and reduced.What the map shows Across Los Angeles and other monitored areas, the satellite’s new map separates nitrogen dioxide into separate plumes that were previously mixed.Based on these observations, Zachary Fasnacht of NASA’s Goddard Space Flight Center demonstrated that PACE can distinguish nearby emission sources rather than merging them into a single signal.In these…

Exposure to “permanent chemicals” during pregnancy may increase the risk of childhood asthma, according to a new study from Sweden. Researchers at Lund University have found that prenatal exposure to extremely high levels of per- and polyfluoroalkyl substances known as PFAS in drinking water is consistent with high rates of childhood asthma in communities that have dealt with decades of pollution. The findings, published Thursday in the journal PLOS Medicine, are noteworthy. Exposure to PFAS causes a myriad of well-documented health effects, but its association with asthma has not been well studied. “We were surprised because we had no expectations…

How does the brain eliminate waste products? It relies on a specialized drainage network known as the lymphatic system. Scientists have been working to understand how this system works, pushing brain imaging techniques to new limits in the process.
