(Phys.org) —A team of planetary scientists with members from several research centers in France, has developed a theory that suggests that one of the reasons that Greenland's ice shelf is melting faster than models suggest, ...
(Phys.org)—Instead of dust-bunnies under the sofa, this dust helps form ice crystals that are at the heart of clouds. Researchers at Pacific Northwest National Laboratory used dust's loftier disposition to create a new ...
