(Phys.org)—A very large team of European astronomers has found that they were able to measure the degree of electrical activity in thunderstorms using information derived by collisions of space particles with Earth's atmosphere. ...
Some of the same chemical reactions that occur in the atmosphere as a result of smog and ozone are actually taking place in your house while you are cleaning. A researcher in Drexel's College of Engineering is taking a closer ...
