Jan. 13 (UPI) -- How can cultures that developed on opposite sides of the world come to similar understandings about colors, shapes, familial relationships and other categorical systems? The traditional explanation for this cross-cultural continuity is that humans are born with categories wired into their brains. Advertisement Researchers with the Annenberg School for Communication at the University of Pennsylvania, however, have an alternative explanation. It's not the human brain, exactly, that yields categorical consensus across disparate groups, researchers contend in a new paper, published in the journal Nature Communications, but the dynamics of consensus building among large groups of people. The phenomenon of "category convergence" has long been recognized by archaeologists in th...

Science
Oct. 5 (UPI) -- NASA's official watchdog panel has renewed calls for the agency to move faster on a plan to better track and mitigate dangers posed by orbiting debris in space. Members of NASA's Aerospace Safety Advisory Panel said during a regular meeting last week that the agency has made some progress, but it needs to focus on space debris as a top priority. Advertisement At stake is the safety of astronauts, anyone going into space on planned private missions and the nation's growing fleet of satellites used for national security, communications and scientific observation.
