Bird bones may be hollow, but they are also heavy
03/21/2010 - 23:00
For centuries biologists have known that bird bones are hollow, and even elementary school children know that bird skeletons are lightweight to offset the high energy cost of flying. Nevertheless, many people are surprised to learn that bird skeletons do not actually weigh any less than the skeletons of similarly sized mammals. In other words, the skeleton of a two-ounce songbird weighs just as much as the skeleton of a two-ounce rodent.

How dinosaurs rose to prominence

Marine conditions of Aralar mountain range of 120 million years ago
03/21/2010 - 23:00
The Early Aptian (120 million years ago) was an age of intense volcanic activity on Earth, eruptions that emitted large amounts of carbon dioxide into the atmosphere, thus causing a revolution in the carbon cycle. As a consequence, great changes happened in the whole of the terrestrial system. A researcher in Spain has studied how these changes happened in the marine environment of the Aralar mountain range (at that time it was under the sea) in the Basque Country, and found more than one surprise.

When it comes to 3-D puzzles, Rubik's Cube pales in comparison with the latest creation from a team of geophysicists. They have just put the finishing touches on a 20-year effort to precisely describe the relative movements of the interlocking tectonic plates that make up about 97 percent of Earth's surface.
