A new study presented at the recent American Association for the Advancement
of Science meeting in Chicago shows that when men see photos of scantily
clad women their brain registers the women as objects to be acted
on. SciAm

- '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. BBC
- 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"

with the magnetic signals they detect. BBC

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.
