Alligators' Muscles Move Lungs Around For Sneaky Maneuvers In Water

Without a ripple in the water, alligators dive, surface or roll sideways, even though they lack flippers or fins. University of Utah biologists discovered gators maneuver silently by using their diaphragm, pelvic, abdominal and rib muscles to shift their lungs like internal floatation devices: toward the tail when they dive, toward the head when they surface and sideways when they roll.

T.J. Uriona, a University of Utah doctoral student in biology, holds a juvenile American alligator. Uriona and his professor, biologist C.G. Farmer, have published a study showing how alligators use muscles to move their lungs backward to help them dive, and to one side or the other to roll.

Why queen bees are made and not born

The ability to create bee "super queens" that can shrug off disease has arisen from the discovery of how royal jelly works.

A study of royal jelly, the creamy, thick secretion used to feed honey bee larvae and groom queens, has been discovered to have a powerful effect on genes and scientists now know how to mimic its effects, which will be give them an invaluable new technology to help make resistant bee strains.

Ornithologists announce discovery of new bird species

The announcement of the discovery of a new bird comes with a twist: It's a white-eye, but its eye isn't white. Still, what this new bird lacks in literal qualities it makes up for as one of the surprises that nature still has tucked away in little-explored corners of the world.

Ornithologists, including one from Michigan State University, describe for science a new species of bird from the Togian Islands of Indonesia - Zosterops somadikartai, or Togian white-eye, in the March edition of The Wilson Journal of Ornithology.
