Talkin' 'bout
Regeneration

A
powdered compound made from pig bladders could hold the key to regenerating human limbs. In a test case from 2005, a man who had accidentally severed off his fingertip was able to regrow it entirely in four weeks.

The U.S. Army is researching human limb regeneration because of its potential to help soldiers who have lost limbs in battle.

Walk the
Walk

W
hen a wild dolphin became trapped in a marina lock in the 1980s, she was rescued and cared for at a dolphin sanctuary in Adelaide, Australia, where she must have picked up a few tricks from the other dolphins. Nearly twenty years later, marine biologists spotted several wild dolphins near Adelaide performing a trick known as tail walking—rising out of the water to a vertical position and gliding backward for several feet powered by flicks of the tail. Tail walking is a swell trick for trained performing dolphins, but it serves no known purpose in the wild. The biologists concluded that the rescued dolphin learned the skill during her time in the sanctuary and taught it to her pod-mates when she was returned to the wild.

Sleep the
Sleep

D
olphins are “conscious breathers,” meaning that they have to be awake, or semi-awake, to remember to breathe. If they fall asleep entirely, they'll stop breathing and drown. So, dolphins don't ever go completely to sleep. Instead, they rest in short bursts throughout the day, sometimes shutting one eye and resting half their brain while keeping the other eye open and the other half of the brain alert.

Naptime

K
oalas sleep as many as twenty-two hours a day.

Koalas feed almost exclusively on eucalyptus leaves, which provide very little energy (thus the long naptime) and are highly toxic to almost all animals except koalas.
