Presto! It's A Semiconductor -- Researchers Transform The Properties O
Researchers at the University of Pennsylvania may not have turned lead into gold as alchemists once sought to do, but they did turn a quantum dot -- nanoscale crystals -- from an insulator to a semiconductor. Their findings represent a key step towards the fabrication of functional nanocrystal-based devices and circuits. NASA Successfully Demonstrates Innovative Nanosatellite System
Big things can come in small packages, and engineers at NASA's Johnson Space Center are making progress on a tiny spacecraft that holds major promise for future exploration. Work on the volleyball-sized Miniature Autonomous Extravehicular Robotic Camera (Mini AERCam) moved forward with successful initial tests on its docking system. The Mini AERCam is designed to help astronauts and ground crews see outside the spacecraft during a mission. Marshes Tell Story Of Medieval Drought, Little Ice Age, And European S
Sediment layers from a tidal marsh in the Hudson River Estuary provide great details on the area's climate. They have preserved pollen from plants, seeds, and other materials. These past remnants allowed researchers from Columbia University, New York, N.Y. and NASA to see evidence of a 500 year drought from 800 A.D. to 1300 A.D., the passing of the Little Ice Age and the impacts of European settlers. Northwest Science &Technology
Collection of articles from this University of Washington publication highlighting "science and technology news in the greater Pacific Northwest (Washington, Oregon, Idaho, Montana, Wyoming, Alaska, British Columbia)."Stories cover topics such as Northwest windstorms, sustainable building, radio frequency identification (RFID), and space medicine. The "SciScape"section includes articles for children. Collaborative Cross To Provide Powerful Resource For Mouse Model Resea
A thousand new strains of mice being bred at Oak Ridge National Laboratory as part of an international effort will provide researchers with a powerful resource for studying human disease. The Shape Of Life: Research Sheds Light On How Cells Take Shape
Brown University physicists have identified a surprising force in pattern formation -- physical force. Results of their work shed important light on how life takes shape inside cells and are published in the Proceedings of the National Academy of Sciences. New Gene Linked To Bipolar Disorder
A new gene linked to both depression and bipolar disorder has been identified by University College London and Danish researchers. Software Helps Doctors Calculate Heart Attack Risk
Pioneering computer software is helping doctors to decide how best to treat patients admitted to hospital with suspected heart attacks. Horatio Alger, Jr. (1832-1899)
