Frozen squirrels and the human brain

For the seventh episode of the BBC Earth Podcast, we’re bringing
your stories about adaptation. Did you know, during its 8 month
hibernation, the Arctic ground squirrel can survive
with a core temperature of 3 degrees below freezing? Scientists
have been studying this astounding little rodent’s long, cold
sleep to understand whether its hibernation can help
revolutionise understanding of our own brains. We also
meet the ‘Lightning Bug Lady’ Lynn
Faust who has studied fireflies her entire life and
tells us about the beautiful display these creatures put
on, when trying to attract a mate. We speak to a man who
describes nature’s resurgence following the catastrophic nuclear
disaster in Chernobyl and get to grips with some surprising
silver linings to a human catastrophe.
