Electronics may confuse a bird’s ‘compass’
Birds use Earth’s magnetic field to help guide them as they migrate. A new study suggests that electromagnetic radiation given off by some electronic devices may act like “noise” and confuse the long-traveling birds.

Even penguins get the flu
Scientists have just identified ‘live’ bird flu virus in Antarctic penguins. But the infections may not be novel. There are some signs these germs have been infecting local wildlife for up to 80 years.

Surprise! Fossils in a flash
By studying how dead tissues decay — or turn to ‘instant’ fossils — scientists are gleaning helpful clues to what ancient life looked like.

Helping birds doctor their babies
Darwin’s finches will soften their nests by weaving in fibers, such as stray bits of cotton. An observant biologist offered those birds some insecticide-treated cotton and the birds took it, which saved their young from deadly parasites.

Move over cheetah: Mite sets new speed record
A super-speedy species sprints faster than any other land animal — for its size, a new study finds. Scientists may someday tap this tiny mite’s technique to create robots and other devices that zip around at sensational speeds!
