When a University of Washington researcher listened to the audio picked up by a recording device that spent a year in the icy waters off the east coast of Greenland, she was stunned at what she heard: whales singing a remarkable variety of songs nearly constantly for five wintertime months.
In a curious evolutionary twist, several species of a commonly studied fruit fly appear to have incorporated genetic material from a virus into their genomes.
To fight off competition for a partner that it is courting, a male mourning cuttlefish transforms the half of its body not facing its would-be paramour to display female markings, while still displaying mating patterns with the side nearest her. This allows it to pretend it is not a rival to another nearby male while still covertly courting.
Hummingbirds manage to maintain complete control over their aerial position, even when their tiny bodies are being hammered by raindrops.
At least 79 new species of sharks have been discovered by the scientists in South Carolina. Researchers at the Hollings Marine Laboratory at Fort Johnson on Charleston Harbor studied the DNA by allowing the genes to stick to the molecules. This way the researchers were able to compare the genetic coding of the 79 new species with that of the other species. They found that the newly discovered sharks are different from others and called them the "cryptic" species.
The change in climate and genetic exchange has caused the polar bears and brown bears to reunite and interbreed, according to a new study.
