Saturn’s Secondary Aurora Is Much More Like Jupiter’s In Origin Than It Is The Earth’s Posted: 21 Jun 2008 07:00 PM CDT Researchers have discovered a secondary aurora sparkling on Saturn and also started to unravel the mechanisms that drive the process. Their results show that Saturn's secondary aurora is much more like Jupiter's in origin than it is the Earth's.

Low Testosterone Appears To Increase Long-term Risk Of Death Posted: 21 Jun 2008 07:00 PM CDT Men may not live as long if they have low testosterone, regardless of their age, according to a new study. The new study adds to the scientific evidence linking deficiency of this sex hormone with increased death from all causes over time--so-called "all-cause mortality."

Getting Wrapped Up In Solar Textiles Posted: 21 Jun 2008 07:00 PM CDT Expert in the integration of solar cell technology in architecture are creating designs for flexible photovoltaic materials that may change the way buildings receive and distribute energy.

Promising Chinese Herbal Targets Identified For Acute Pancreatitis Posted: 21 Jun 2008 07:00 PM CDT Researchers have determined the genetic treatment mechanism of Chaiqinchengqi decoction, which is a basic Chinese herbal compound commonly used in the treatment of acute pancreatitis. It can upregulate sarco/endoplasmic reticulum Ca2+-ATPase (SERCA) mRNA expression of pancreatic tissue as well as inhibit the elevation of calcium concentration in pancreatic acinar cells while relieving pancreatic lesions in an acute pancreatitis model of rats.

Experimental Phone Network Uses Virtual Sticky Notes Posted: 21 Jun 2008 07:00 PM CDT The rapid convergence of social networks, mobile phones and global positioning technology has given engineers the ability to create something they call "virtual sticky notes," site-specific messages that people can leave for others to pick up on their mobile phones.

Chill Out, Your Computer Knows What’s Best For You Posted: 21 Jun 2008 07:00 PM CDT Computers are starting to become more human-centric, anticipating your needs and smoothly acting to meet them. The technologies under development leave humans free to concentrate on their real work instead of having to think about the computer and how to operate it.

Exciton-Based Circuits Eliminate A ‘Speed Trap’ Between Computing And Communication Signals Posted: 21 Jun 2008 01:00 PM CDT Particles called excitons that emit a flash of light as they decay could be used for a new form of computing better suited to fast communication, physicists at UC San Diego have demonstrated.

Huntington's Disease: Discovery Will Assist Treatment And Research Into Fatal Brain Disorder Posted: 21 Jun 2008 01:00 PM CDT Research using newly developed Magnetic Resonance Imaging technology could soon allow clinicians to confirm Huntington's disease before symptoms appear in people who have the gene for the fatal brain disease.

Digital Water Pavilion Makes A Splash In Spain Posted: 21 Jun 2008 01:00 PM CDT An MIT-designed building with walls made entirely of water is being unveiled Thursday at the opening of the Zaragoza World Expo in Spain. This is the first of its kind and illustrates the potential of digital architecture to create spaces that dynamically adjust to people and conditions. The "water walls" that make up the structure are generated by high-speed computer controlled solenoid valves. They can be programmed to take varying shapes, to display patterns, images and text, and to respond dynamically to input from sensors.

New Weapon For Attacking Tumor Invasion And Metastasis Posted: 21 Jun 2008 01:00 PM CDT Scientists have determined that AMD3100, originally developed in acquired immune deficiency syndrome treatment, could markedly inhibit spreading of colorectal cancer cells by blocking a new pair of ligands and its unique receptor. This effect differs from the usual inhibition by a conventional chemotherapic agent that is more specific to cancer cells with high metastatic potential.

Wavelets Crunch Through Doctors' Day Long Struggle To Diagnose Brain Tumors Posted: 21 Jun 2008 01:00 PM CDT Today if doctors devote a full day to analysis and expert thought, they may be able to provide just half a dozen patients with a diagnosis of the precise type of brain tumor they face. Now researchers have devised an automated technique that can give a preliminary analysis of the precise brain tumor type within seconds.

Elderly's Restless Nights Helped By Ancient Martial Art Posted: 21 Jun 2008 01:00 PM CDT More than half of all older adults complain about having difficulties sleeping. Most don't bother seeking treatment. Those who do usually turn to medications, which can lead to other health problems. Now, researchers report that practicing Tai Chi Chih, the Westernized version of the 2,000-year-old Chinese martial art, promotes sleep quality in older adults with moderate sleep complaints.

Novel Compound May Treat Acute Diarrhea Posted: 21 Jun 2008 07:00 AM CDT In a development that may lessen the epidemic of diarrhea-related deaths among children in developing countries, scientists have discovered a novel compound that might lead to an inexpensive, easy-to-take treatment.

Project Succeeding To Relocate Caspian Terns Posted: 21 Jun 2008 07:00 AM CDT A major initiative to create alternative nesting sites for the largest colony of Caspian terns in the world -- and to help protect juvenile salmon and steelhead in the Columbia River -- is finding early success.

New Inhibitors Of Estrogen-dependent Breast Cancer Cells Posted: 21 Jun 2008 07:00 AM CDT Researchers have discovered a new family of agents that inhibit the growth of estrogen-dependent breast cancer cells. The finding has opened an avenue of research into new drugs to combat estrogen-dependent breast cancers.

Aquatic Insect 'Family Trees' Provide Clues About Sensitivity To Pollution Posted: 21 Jun 2008 07:00 AM CDT A new study in the Proceedings of the National Academy of Sciences shows that examining an insect's "family tree" might help predict a "cousin" insect's level of tolerance to pollutants, and therefore could be a reliable way to understand why certain insect species thrive or suffer under specific ecological conditions.

Educational Benefits Of Social Networking Sites Uncovered Posted: 21 Jun 2008 07:00 AM CDT In a first-of-its-kind study, researchers have discovered the educational benefits of social networking sites such as MySpace and Facebook. The same study found that low-income students are in many ways just as technologically proficient as their counterparts.
