Parents, take note. Lying to your
children and convincing them that Santa Claus is real could be damaging, as it
may undermine you kid’s trust in you, researchers said. Million of parents across
the world convince their kids Father Christmas is real. According to
researchers, parents may not be motivated by purely creating magic for their children,
but by a desire to return to the joy of childhood themselves. Children’s trust
in their parents may be undermined by the Santa lie, they said. It they are
capable of lying about something so special and magical, can they be relied
upon to continue as the guardians of wisdom and truth? The morality of making
children believe in such myths has to be questioned.

Booze Is Bad For Your Brain But Jogging Helps
The holiday season is a good time
for a reminder that alcohol can do bad things to the brain. Studies on animals
suggest that it reduces the number of neutrons in the hippocampus, the brain’s
memory centre, and weakens the mitochondria there. As mitochondria help produce
energy within cells, their impairment can damage or kill brain cells. But two new
animal studies offer some succor: Aerobic exercise, it turns out, may meliorate
some of the effects of heavy drinking on the brain. Both studies were presented
earlier this month at the annual Society for Neuroscience meeting in San Diego.
The first, conducted by physiologists at the University of Louisville, involved
adult male mice. Every day for 12 weeks – the equivalent of several human years
– groups of mice received either injections of alcohol or salt water. Half the
animals in each group were then put through daily treadmill workouts. These exercise
sessions were short but intense. The second study focused on binge-drinking. Researchers
from the University of Houston inserted tubes into the stomachs of female rats
to provide consistent doses of either alcohol or a nonalcoholic liquid one
night for 11 weeks. Half the rats in each group were then kept idle in their cages
for the rest of the week, while the other half ran on wheels for up to two
hours, three days a week. In each study, the brains of the rodents that
exercised after receiving alcohol were substantially different from those of their
sedentary counterparts. The inactive mice had weakened mitochondria in many
neurons; the runners had hardy mitochondria. The sedentary rats given alcohol
had almost 20% fewer neurons in their hippocampi than the control animals. The rats
that were made to work out, though, had as many neurons as the controls.
