Mite-y discoveries!
Two teens from Russia discovered tiny mites living inside grass-like plants called rushes. Three of the species they turned up are new to science.

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!

Don’t mess with a frustrated fish
When a trout doesn't get the snack it expected, look out. These fish get aggressive. Sometimes they can defeat even bigger fish.

These insects thirst for tears
In some parts of the world, insects will drop by for a savory beverage. Interestingly, neither a croc — nor a scientist who offered his eyes up to ‘tear-sipping’ bees — seemed bothered much by the freeloaders.

One plus to wearing stripes
A zebra’s black-and-white coat doesn’t offer cooling or camouflage, researchers find. Instead, its stripes appear to keep away biting flies — and deadly diseases.

Sea otters picked up swine flu
A new study finds that large numbers of sea otters off of the U.S. Pacific coast have been exposed to the ‘pandemic’ type of this killer virus.

When a species can’t stand the heat
When temperatures rise, New Zealand’s tuatara produce more males. With global warming, that could leave the ancient reptile species with too few females to avoid going extinct.

Explainer: How invasive species ratted out the tuatara
The introduction of rats to New Zealand led to huge population losses of the ancient tuatara. These uncommon reptiles vanished from the mainland. This left isolated populations to survive on several dozen isolated islands.
