| NASA Mars rover finds mineral vein deposited by water Posted: 07 Dec 2011 03:20 PM PST NASA's Mars Exploration Rover Opportunity has found bright veins of a mineral, apparently gypsum, deposited by water. Analysis of the vein will help improve understanding of the history of wet environments on Mars.  |
| SETI search resumes at Allen Telescope Array, targeting new planets Posted: 07 Dec 2011 10:48 AM PST The Allen Telescope Array (ATA) is once again searching planetary systems for signals that would be evidence of extraterrestrial intelligence. Among its first targets are some of the exoplanet candidates recently discovered by NASA's Kepler space telescope.  |
| One of the world's smallest electronic circuits created Posted: 07 Dec 2011 10:29 AM PST Scientists have engineered one of the world's smallest electronic circuits. It is formed by two wires separated by only about 150 atoms or 15 nanometers.  |
| Best routes found to self-assembling 3-D shapes Posted: 07 Dec 2011 08:30 AM PST Researchers have found optimal configurations for creating 3-D geometric shapes — like tiny, highly simplified geodesic domes that assemble by themselves. The team developed the algorithmic tools and tested selected configurations. The research may lead to advances from drug-delivery containers to 3-D sensors and electronic circuits.  |
| Vampire star reveals its secrets Posted: 07 Dec 2011 07:54 AM PST Astronomers have obtained the best images ever of a star that has lost most of its material to a vampire companion. By combining the light captured by telescopes at the European Southern Observatory's Paranal Observatory they created a virtual telescope 130 meters across with vision 50 times sharper than the NASA/ESA Hubble Space Telescope. Surprisingly, the new results show that the transfer of mass from one star to the other in this double system is gentler than expected.  |
| New '3-D' transistors promising future chips, lighter laptops Posted: 06 Dec 2011 12:15 PM PST Researchers have created a new type of transistor made from a material that could replace silicon and have a 3-D structure instead of conventional flat computer chips.  |
| Computer simulations shed light on the physics of rainbows Posted: 06 Dec 2011 12:15 PM PST Computer scientists who set out to simulate all rainbows found in nature, wound up answering questions about the physics of rainbows as well. The scientists recreated a wide variety of rainbows by using an improved method for simulating how light interacts with water drops of various shapes and sizes. Their new approach even yielded realistic simulations of difficult-to-replicate "twinned" rainbows that split their primary bow in two.  |
