Geologists push back date basins formed, supporting frozen Earth theory Even in geology, it's not often a date gets revised by 500 million years. But University of Florida geologists say they have found strong evidence that a half-dozen major basins in India were formed a billion or more years ago, making them at least 500 million years older than commonly thought. 'Smart' materials get smarter with ability to better control shape and size A dynamic way to alter the shape and size of microscopic three-dimensional structures built out of proteins has been developed by biological chemist Jason Shear and his former graduate student Bryan Kaehr at The University of Texas at Austin. Study debunks theory Asian students are top notchers in US A belief that Asian-Americans are taking over US universities, outperforming other groups and grabbing the bulk of math, science and engineering degrees has been debunked in a landmark study. Microsoft to sell Office, OneCare for $70 a year (AP) -- Microsoft Corp. will begin selling its Office programs to consumers on a subscription basis starting mid-July, in a bid to reach thrifty PC buyers who would otherwise pass on productivity software. 10,000 people in world-first cerebral palsy study Researchers from the University of Adelaide, Australia, have launched the largest study of its kind in the world in a bid to better understand the possible genetic causes of cerebral palsy. Some fundamental interactions of matter found to be fundamentally different than thought Collisions have consequences. Everyone knows that. Whether it's between trains, planes, automobiles or atoms, there are always repercussions. But while macroscale collisions may have the most obvious effects - mangled steel, bruised flesh - sometimes it is the tiniest collisions that have the most resounding repercussions. Researchers identify potential new drug candidates to combat 'bird flu' As the specter of a worldwide outbreak of avian or "bird flu" lingers, health officials recognize that new drugs are desperately needed since some strains of the virus already have developed resistance to the current roster of anti-flu remedies. First images of solar system's invisible frontier NASA's sun-focused STEREO spacecraft unexpectedly detected particles from the edge of the solar system last year, allowing University of California, Berkeley, scientists to map for the first time the energized particles in the region where the hot solar wind slams into the cold interstellar medium. Simple insulation could combat heat, cold and noise Around the world, an estimated one billion people--mostly in rural villages and the shanty towns surrounding developing-world cities--live in houses whose roofs are nothing more than thin sheets of corrugated metal. These houses become unbearably hot in the summer, freezing in the winter (especially in high-altitude regions), and deafeningly noisy when heavy rains pound on the bare metal. Study shows quantum dots can penetrate skin through minor abrasions Researchers at North Carolina State University have found that quantum dot nanoparticles can penetrate the skin if there is an abrasion, providing insight into potential workplace concerns for healthcare workers or individuals involved in the manufacturing of quantum dots or doing research on potential biomedical applications of the tiny nanoparticles. ... |
