• 'Fidelity gene' found in voles
  Previous studies indicated a hormone called vasopressin encourages pair-bonding in prairie voles. Scientists had also noticed that promiscuous voles have fewer vasopressin (V1a) receptors, in a bit of their forebrain called the ventral pallidum region.To prove vasopressin has a "taming" effect, the researchers gave meadow voles extra V1a receptors in the ventral pallidum region of their brains.

• Mammals have multiple timers
  One body clock reponds to light-dark cycles, but the other doesn't. Our brains contain more than one biological clock, US researchers have shown. They believe that problems such as jet lag are caused when two of the clocks become out of step with each other. NSU

  Amazingly..., this study does seem to confirm that birds can "reset" their navigation systems daily by comparing the direction of the sunset with the magnetic signals they detect. BBC

• Babies' hands babble
  Speech or sign - it's all the same to a baby. 6 September 2001
  Baby talk: tots shown sign language babble with their hands. Š L. Petitto et al. Babies exposed to sign language make babbling gestures - even if they can hear perfectly. The hand-waving mirrors the first vocal efforts of babies exposed to speech. It suggests that children are sensitive to the rhythms underlying all language, regardless of whether it its expressed with the hands or the mouth. full text at Nature

• Bats eat birds on the wing
  Migrating birds should beware of high-flying bats.
  7 August 2001
  The greater noctule bat waits for the fly-by. As if the arduous journey between northern Europe and warmer climes weren't enough, birds migrating at night may be at the mercy of predatory bats, new research suggests.
