Ultra-intense Laser Blast Creates True 'Black Metal'
"Black gold"is not just an expression anymore. Scientists at the University of Rochester have created a way to change the properties of almost any metal to render it, literally, black. The process, using an incredibly intense burst of laser light, holds the promise of making everything from fuel cells to a space telescope's detectors more efficient -- not to mention turning your car into the blackest black around. Mars: Impact Craters In Tyrrhena Terra Clearly Imaged
The High Resolution Stereo Camera on board ESA's Mars Express obtained images of the Tyrrhena Terra region on Mars. Tyrrhena Terra is part of the ancient, heavily cratered southern Martian highlands. The region is located north of Hellas Planitia, the largest impact basin on Mars. The image scene exhibits three impact craters, located at the eastern border of Tyrrhena Terra with Hesperia Planum. Researchers Recognize 'Lower-Energy' Varieties Of Coastal Islands
A different style of coastal barrier islands that forms under lower-energy conditions than classic ocean-facing barriers, such as North Carolina's Outer Banks, has been identified by coastal geological researchers at Duke University and the University of Ulster in Northern Ireland. The new style of islands is typically found in protected bays and lagoons. 'Nanoshells' Simultaneously Detect And Destroy Cancerous Cells
Researchers at Rice University in Texas have developed a new approach to fighting cancer, based on nanoscale particles that can both detect and destroy cancerous cells. The report appears in the April 13 issue of the American Chemical Society's journal Nano Letters. ACS is the world's largest scientific society. Genetic Differences Point To Ethnic And Racial Disparities In Colorect
Risk of developing colorectal cancer is known to differ across ethnic and racial groups, and now an analysis of 26 studies, involving over 25,000 participants shows that some of these disparities might be explained by distinct patterns of genetic inheritance. Scientists Discuss Improved Biopesticides For Locust Control In West A
Two Virginia Tech scientists contributed by invitation to an international scientific meeting called by Abdoulaye Wade, president of Senegal, to identify strategies for the control of the ongoing locust outbreak in West Africa. Last year, locusts stripped fields of crops and trees of foliage across several countries, causing severe income and food supply loss. 50-year-old Mystery Solved: Protein Tags Regulate Key Ion Channel
A recently discovered process known as sumoylation -- until now thought to be active only in the nucleus -- also occurs near the cell's surface where it regulates proteins, providing a novel target for the development of new drugs. Researchers show that sumoylation regulates the flow of potassium ions, which determine whether "excitable"cells in the brain, heart and skeletal muscles "fire." Identification: Key to Aphids Commonly Found in Small Grains, Corn, an
An illustrated, interactive guide for identifying "the aphid species that are most commonly found in small grains (wheat, rye, and barley), corn, and sorghum in California."Includes photographs of each aphid, and links to related information on damage and management. From the Statewide Integrated Pest Management Program (IPM), University of California, Davis. Sex Life May Hold Key To Honeybee Survival
The number and diversity of male partners a queen honeybee has could help to protect her children from disease, say scientists, who are investigating possible causes of the widespread increase in bee deaths seen around the world. Gallery: Inside the Freedom Tower
