Geophysicists Detect A Molten Rock Layer Deep Below The American South
A sheet of molten rock roughly 10 miles thick spreads underneath much of the American Southwest, some 250 miles below Tucson, Ariz. From the surface, you can't see it, smell it or feel it. But geophysicists detected the molten layer witha comparatively new and overlooked technique for exploring the deep Earth that uses magnetic eruptions on the sun. Spitzer Spies Eternal Life Of Stardust
A new image from NASA's Spitzer Space Telescope is helping astronomers understand how stardust is recycled in galaxies. The cosmic portrait shows the Large Magellanic Cloud, a nearby dwarf galaxy named after Ferdinand Magellan, the seafaring explorer who observed the murky object at night during his fleet's historic journey around Earth. Now, nearly 500 years after Magellan's voyage, astronomers are studying Spitzer's view of this galaxy to learn more about the circular journey of stardust, from stars to space and back again. [Scary] Pregnant woman says 'maternal instinct' helped her kill attack
FORT MITCHELL, Ky. - A pregnant woman who killed her attacker said a maternal instinct helped her fight off the woman who investigators believe was after her unborn child."I do believe that I fought harder because it was for my child,"Sarah Brady told ABC's "Good Morning America"in interviews aired Sunday and Monday. "It is a maternal instinct to protect your child to the very end."Katherine Smith, 22, died Thursday after luring Brady to her apartment to pick up a package supposedly delivered to the wrong address. When Smith pulled out a knife and attacked the pregnant woman, Brady fought back, striking Smith on the head with an ash tray and stabbing her three times with her own knife, police said. Brady, 26, said she didn't know Smith before the two met at Smith's apartment and can't be certain why Smith wanted to kill her."I really am not sure what was going through her mind,"Brady told ABC. "The only thing I thought was that she was going to kill me and my child and that is the only thing that ran through my mind." Clues To Cause Of Difficulty With Swallowing In Children
Eosinophilic esophagitis (EE) is disease that was first described in children only 20 years ago, but has shown a rising incidence in both children and adults.

University of Colorado at Boulder researchers say a bizarre group of microbes found living inside rocks in an inhospitable geothermal environment at Wyoming's Yellowstone National Park could provide tantalizing new clues about ancient life on Earth and help steer the hunt for evidence of life on Mars. Sea Urchins' Unexpectedly Diverse 'Innate' Immune Capability Points To
Inside that seemingly docile sea urchin there's a surprisingly active innate immune system, probably utilizing previously unrecognized immune mechanisms that may also actively function in vertebrates, including humans, researchers at George Washington University, Washington, D.C., say. "Discovering this capability goes completely against the long-accepted paradigm that the innate immune system (is) 'perfect' in terms of meeting lower animals' needs,"laboratory head L. Courtney Smith added. "It was a big surprise, which continues to astound us." Discarded Placentas Deliver Researchers Promising Cells Similar To Emb
Routinely discarded as medical waste, placentas could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cellsand available now as an early online publication in Stem Cells Express. Physicist Sees Terahertz Imaging As Ultimate Defense Against Terrorism
John Federici, PhD, professor, department of physics, New Jersey Institute of Technology (NJIT) and other physicists at NJIT recently received a U.S. Patent for a Teraherz imaging system and method. Since 1995, Terahertz imaging has grown in importance as new and sophisticated devices and equipment have empowered scientists to understand its potential. What Do 'Ecolabels' Tell About Food?
In a Nutrition Today article, William Lockeretz, PhD, and Kathleen Merrigan, PhD, both professors at the Friedman School of Nutrition Science and Policy at Tufts University, note that the "organic sector has been growing at an annual rate of 20% for the past decade ... [and] ecolabels could soon move into the mainstream."
