Every animal with bones has blood with hemoglobin, which binds with oxygen and makes the blood appear red. Every animal, that is, except one. The ocellated icefish (Chionodraco rastrospinosus) has gin-clear blood. And it has no scales. And it lives nowhere but the inky depths down to 3,200 feet (1 kilometer) in the icy waters off Antarctica.

A new university-led study with NASA participation finds ancient Antarctica was much warmer and wetter than previously suspected. The climate was suitable to support substantial vegetation -- including stunted trees -- along the edges of the frozen continent.

After more than two decades of drilling in Antarctica, Russian scientists have reached the surface of a gigantic freshwater lake hidden under miles of ice for some 20 million years — a lake that may hold life from the distant past and clues to the search for life on other planets.
