*Samples of rock, sediment from beneath the sea-floor help explain quakes like Japan’s*

New samples of rock and sediment from the depths of the eastern Pacific Ocean may help explain the cause of large, destructive earthquakes similar to the Tohoku Earthquake that struck Japan in mid-March.

Nearly 1,500 meters (almost one mile) of sediment cores collected from the ocean floor off the coast of Costa Rica reveal detailed records of some two million years of tectonic activity along a seismic plate boundary. (more…)

Making a Spectacle of Star Formation in Orion

Looking like a pair of eyeglasses only a rock star would wear, this nebula brings into focus a murky region of star formation. NASA’s Spitzer Space Telescope exposes the depths of this dusty nebula with its infrared vision, showing stellar infants that are lost behind dark clouds when viewed in visible light.

Best known as Messier 78, the two round greenish nebulae are actually cavities carved out of the surrounding dark dust clouds. The extended dust is mostly dark, even to Spitzer’s view, but the edges show up in mid-wavelength infrared light as glowing, red frames surrounding the bright interiors. Messier 78 is easily seen in small telescopes in the constellation of Orion, just to the northeast of Orion’s belt, but looks strikingly different, with dominant, dark swaths of dust. Spitzer’s infrared eyes penetrate this dust, revealing the glowing interior of the nebulae. (more…)

Research Reveals New Secret Weapon For Le Tour

Winning margins in the Tour de France can be tight. In 2010 just 39 seconds separated the top two after more than 90 hours in the saddle. When every second counts, riders do all they can to gain competitive advantage, from aerodynamic carbon fibre bikes to the latest sports nutrition.

Now there could be a new, completely legal and rather surprising weapon for riders aiming to shave vital seconds off their time – beetroot juice. (more…)

Significant Natural Gas Resources Remain to Be Discovered in Cook Inlet, Alaska

The Cook Inlet Region of Alaska contains an estimated mean of 19 trillion cubic feet of natural gas, about 600 million barrels of oil, and 46 million barrels of natural gas liquids, according to a new assessment by the U.S. Geological Survey (USGS). This estimate is of undiscovered, technically recoverable oil and gas resources, and includes both unconventional and conventional resources.

These gas estimates are significantly more than the last USGS assessment of southern Alaska in 1995, in which a mean of 2.14 trillion cubic feet of gas was estimated. This increase in the undiscovered resource is attributed to new geologic information and data. (more…)

Caltech-led Researchers Measure Body Temperatures of Dinosaurs for the First Time

Some Dinosaurs Were as Warm as Most Modern Mammals

PASADENA, Calif.—Were dinosaurs slow and lumbering, or quick and agile? It depends largely on whether they were cold or warm blooded. When dinosaurs were first discovered in the mid-19th century, paleontologists thought the y were plodding beasts that had to rely on their environments to keep warm, like modern-day reptiles. But research during the last few decades suggests that they were faster creatures, nimble like the velociraptors or T. rex depicted in the movie Jurassic Park, requiring warmer, regulated body temperatures like in mammals.

By tracking atmospheric features on Neptune, a UA planetary scientist has accurately determined the planet’s rotation, a feat that had not been previously achieved for any of the gas planets in our solar system except Jupiter.

A day on Neptune lasts precisely 15 hours, 57 minutes and 59 seconds, according to the first accurate measurement of its rotational period made by University of Arizona planetary scientist Erich Karkoschka. (more…)
