A young brain for an old bee

We are all familiar with the fact that cognitive function declines as we get older. Moreover, recent studies have shown that the specific kind of daily activities we engage in during the course of our lives appears to influence the extent of this decline. A team of researchers from Technische Universität Berlin are studying how division of labour among honey bees affects their learning performance as they age. Surprisingly, they have found that, by switching their social role, aging honey bees can keep their learning ability intact or even improve it. The scientists are planning to use them as a model to study general aging processes in the brain, and they even hope that they may provide some clues on how to prevent them. Dr. Ricarda Scheiner, leader of the research team, will present these findings at the Society of Experimental Biology Annual Meeting in Glasgow on Wednesday 1st July 2009.
