The vacuum of empty space may be roiling with energy that drives the expansion of space itself, a new hypothesis proposes.
If you cut the leg off a salamander, it grows back. Humans, however, can't manage the trick. The reasons are far from simple, and to some extent are still a bit of a mystery.
Twenty years ago, IBM computer Deep Blue beat the world's greatest chess player in a first for machines. How far has artificial intelligence come since then?
Laser printers that "sculpt" images at miniscule scales could one day make color photos that don't fade over time the way ink does, according to a new study.
One of the still-unsolved mysteries about Earth's history is how the planet became breathable. Now, scientists say the culprit may have been the giant rock slabs that make up Earth's outer shell.
