The sun is zipping through interstellar space more slowly than once thought, suggesting the giant shock wave long suspected of existing in front of the sun is not actually there, researchers say. [More]

In the first university-based planetary science experiment at the National Ignition Facility (NIF), researchers have gradually compressed a diamond sample to a record pressure of 50 megabars (50 million times Earth's atmospheric pressure). By replicating the conditions believed to exist in the cores of several recently discovered "super-Earths" -- extra-solar planets three to 20 times more massive than Earth -- the experiments could provide clues to the formation and structure of these and other giant planets, as well as the exotic behavior of materials at ultrahigh densities.

FDA officials contacted Giant Eagle after positive test for Listeria monocytogenes in shredded lettuce

NANTES, France--Knock, knock. That's not the start of a joke but the hard-luck history of Uranus. New research suggests that the giant planet may have suffered two massive impacts early in its history, which would account for its extreme, mysterious axial tilt.

The news media were abuzz this week with reports of experiments conducted at the Gran Sasso particle detector complex in Italy, apparently showing subatomic particles called neutrinos had traveled from the giant particle accelerator at CERN, outside Geneva, to the Italian detector at a speed just slightly faster than the speed of light -- a result that, if correct, would overturn more than a century of accepted physics theory.

Enceladus, a small satellite of Saturn, has captivated planetary scientists for years with its watery polar geysers and ridgelike surface features known as "tiger stripes." Now it has a new layer of intrigue. The gas and ice escaping from Enceladus and shooting out from the moon's south pole in towering jets, which fill Saturn's diffuse E ring, also seem to rain down on Saturn itself, providing water vapor to the giant planet's upper atmosphere

NEW YORK (Reuters) - New York environmental regulators finalized rules to reduce cooling water intake by power plants and other industrial facilities to reduce fish kills by 90 percent.

By Eugenie Samuel Reich of Nature magazine As Earth's biggest "ear" on the Universe, the giant 305-meter radio dish at Arecibo , Puerto Rico, has played a part in groundbreaking discoveries, searches for alien civilizations and the occasional Holly
