If you find your computer slowing down, its fan running frequently or your web browser opening little windows that stay open for long periods, you might have been cryptojacked. Michigan State computer security scholars Pranshu Bajpai and Richard Enbody explain what that means, how it relates to cryptocurrency, and how to protect yourself and your computer.

The federal government recently decided to treat burning wood to generate electricity as “carbon neutral.” Tufts University’s William Moomaw, the coordinating lead author of the Intergovernmental Panel on Climate Change report on renewable energy, disputes that position and explains what else he believes is wrong with “converting forests into fuel.”

Last week, an Indian man tried to snap a selfie with a wounded bear – which promptly mauled him to death. University of Florida’s Michael Weigold explores the psychological forces that fuel our urge to snap and share photos of ourselves and why some are willing to risk their lives to do so.
