Songbirds Offer Clues To Highly Practiced Motor Skills In Humans:

The melodious sound of a songbird may appear effortless, but his elocutions are actually the result of rigorous training undergone in youth and maintained throughout adulthood. His tune has virtually "crystallized" by maturity. The same control is seen in the motor performance of top athletes and musicians. Yet, subtle variations in highly practiced skills persist in both songbirds and humans. Now, scientists think they know why.

Scientist On Quest For Disappearing Eel:

A Queen's environmental scientist will head a new international study to determine whether American eels - the slimy, snake-like fish considered worldwide to be a food delicacy - are dying from chemical pollution in Lake Ontario.

Photo-monitoring Whale Sharks: Largest Fish In The Sea Appear To Thrive Under Regulated Ecotourism:

Up to 20 meters long and weighing as much as 20 tons, its enormous size gives the whale shark (Rhincodon typus) its name. Known as the 'gentle giant' for its non-predatory behavior, this fish, with its broad, flattened head and minute teeth, eats tiny zooplankton, sieving them through a fine mesh of gill-rakers. Listed as a rare species, relatively little is known about whale sharks, which live in tropical and warm seas, including the western Atlantic and southern Pacific.

Two 'Noses' Are Necessary For Flies To Navigate Well:

Animals and insects communicate through an invisible world of scents. By exploiting infrared technology, researchers at Rockefeller University just made that world visible. With the ability to see smells, these scientists now show that when fly larvae detect smells with both olfactory organs they find their way toward a scented target more accurately than when they detect them with one.
