Despite more violent crimes, it's safer to be a cop today than 50 years ago
There is no doubt that policing is a dangerous profession. But is it safer to be a cop today than it was 50 years ago? Yes, according to a study that analyzed police officer deaths (felonious and non-felonious) in the United States from 1970 to 2016. The study represents one of the most comprehensive assessments of the "dangerousness" of policing to date and provides an important historical contex

NASA's OCO-3 measures how plants grow—and glow

The light is far too dim for us to notice under normal circumstances, but it can be measured with a spectrometer. Called solar-induced fluorescence (SIF), it's the most accurate si
