Buried Antarctic lake teems with life
Last year, scientists drilled 800 meters (roughly a half mile) down through ice to reach a pitch-black Antarctic lake. They now report that lake hosts a thriving community of one-celled microbes.

Fist bumps cleaner than handshakes
A handshake, while welcoming, can transmit lots of germs — many times more than a high five or, especially, a fist bump.

Germs explain some animal behaviors
The bacteria that people and other animals host in and on their bodies are invisible to the eye. Yet they can play a very visible role in behavior. It’s something scientists are just coming to appreciate.

Wind farms: Restaurants for seals?
Scientists have tracked harbor seals visiting the turbines of ocean wind farms. The predators may be drawn by fish that make their homes in the artificial reefs created by the manmade structures.

Meteorites likely wiped out Earth’s earliest life
Enormous meteorites appear to have slammed into Earth several times early in its history. Each mega-smashup would have boiled off oceans and obliterated any bit of life.

Octopus sets egg-nurturing record
Animals will do extraordinary things to help their babies survive. Consider ‘Octomom:’ She sat on one clutch of eggs for nearly 4.5 years.

Fashioning inks to ‘print’ tissues
3-D printing may one day create life-saving tissues and organs for transplants. But first researchers are learning how to tailor cell-filled “inks” for use in inkjet printers.

Dinos ‘quickly’ shrunk into birds
Scientists had long known birds descended from dinosaurs. A study now shows that the morphing from dinos into birds went along with a quick and steady shrinking of their body sizes.

Record Ebola epidemic strikes
A record outbreak of the deadly disease has already claimed nearly 1,000 lives in West Africa. Scientists suspect bats or eating some other wild animals may have triggered the epidemic.
