French scientists say they've determined calcium is involved in long-term memory formation in honeybees. Researchers from France's National Center for Scientific Research, the French Calcium Research Network and the University of Toulouse found calcium acts as a switch between the bees' short- and long-term

By studying in great detail the 'ringing' of a planet-harboring star, a team of astronomers using ESO's 3.6-m telescope have shown that it must have drifted away from the metal-rich Hyades cluster.
