It is generally defined as microorganisms developing the ability to somehow prevent the intended effects of the antibiotic. That… Keep Reading

Research Briefs—Oct. 28, 2014

Physicists transport marbles with optical tractor beam The tractor beam—a long-distance invisible attraction beam—is a legendary staple in science fiction. In real life, moving objects using only light seems absurd, if not impossible. However, in a paper published in Nature Photonics, a team of Australian and American physicists successfully transferred glass marble ten centimetres using… Keep Reading
