What's That Smell?

Aging flies lose middle-term memory

Abstract: Elderly flies lose the capacity to identify evil odors, but memories don't flee immediately after the insects take a sniff, according to new research. The work reveals that old age impairs a middle stage of memory storage, and it links the deficit to a known memory-control gene. The connection provides a starting point for deciphering why brain retention falters with age.
