For early humans, one of the first displays of modern behavior was a sort of beach party and clam bake along the coast of South Africa.
Using a little-known Google Labs widget, computer scientists from UC San Diego and UCLA have brought common sense to an automated image labeling system. This common sense is the ability to use context to help identify objects in photographs.

Robert Quimby has an unusual distinction among astronomers. The Caltech postdoctoral researcher has discovered the two brightest star explosions ever witnessed within months of each other.
Quimby's latest find is supernova 2005ap, which at its peak blazed 100 billion times brighter than the sun and was twice as luminous as the previous record holder, a supernova called 2006gy, which he also discovered.

Celebrated scientist attacked for race comments: "All our social policies are based on the fact that their intelligence is the same as ours - whereas all the testing says not really".
Today there are more than 100 entries on NASA's list of asteroids that just might possibly hit Earth, even if it's less than a one-in-a-million chance. One of them, called Apophis, currently has a risk rating of 1 in 45,000 - serious enough to get people thinking about how to avoid a "cosmic Katrina." Chances are that Apophis will soon no longer be considered a threat, but what about those others? And what about the thousands of space rocks that are expected to be added to the list over the next few years?

Scientists exploring a deep ocean basin in search of species isolated for millions of years found marine life believed to be previously undiscovered, including a tentacled orange worm -- "We don't know what it is," scientists said -- and an unusual black jellyfish near the sea floor.
To enhance the Hubble Space Telescope's science capabilities, two new instruments - the Wide Field Camera 3 and Cosmic Origins Spectrograph - will be installed during the fifth and final shuttle servicing mission to the observatory in August 2008.
