| Touch of gold improves nanoparticle fuel-cell reactions Posted: 12 Mar 2012 08:41 AM PDT Chemists have created a triple-headed metallic nanoparticle that reportedly performs better and lasts longer than any other nanoparticle catalyst studied in fuel-cell reactions. The key is the addition of gold: it yields a more uniform crystal structure while removing carbon monoxide from the reaction.  |
| 3-D Printer with Nano-Precision Posted: 12 Mar 2012 07:19 AM PDT Printing three-dimensional objects with incredibly fine details is now possible using "two-photon lithography". With this technology, tiny structures on a nanometer scale can be fabricated. Researchers have now made a major breakthrough in speeding up this printing technique.  |
| Nanotube technology leading to new era of fast, lower-cost medical diagnostics Posted: 09 Mar 2012 07:56 AM PST Researchers have tapped into the extraordinary power of carbon "nanotubes" to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs. The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug development and other fields.  |
| Magnetic moon: Magnetic anomalies on moon are result of asteroid collision Posted: 08 Mar 2012 11:32 AM PST Astronomers have proposed a surprisingly simple explanation for magnetic anomalies that have baffled scientists since the mid-1960s -- they are remnants of a massive asteroid. The researchers believe an asteroid slammed into the moon approximately four billion years ago, leaving behind an enormous crater and iron-rich, highly magnetic rock.  |
| NASA Mars Orbiter catches twister in action Posted: 07 Mar 2012 08:11 AM PST An afternoon whirlwind on Mars lofts a twisting column of dust more than half a mile (800 meters) high in an image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA's Mars Reconnaissance Orbiter.  |
| Citizen scientists reveal a bubbly Milky Way Posted: 07 Mar 2012 08:11 AM PST A team of volunteers has pored over observations from NASA's Spitzer Space Telescope and discovered more than 5,000 "bubbles" in the disk of our Milky Way galaxy. Young, hot stars blow these bubbles into surrounding gas and dust, indicating areas of brand new star formation.  |
| NASA's twin GRAIL spacecraft begin collecting lunar data Posted: 07 Mar 2012 08:11 AM PST NASA's Gravity Recovery And Interior Laboratory (GRAIL) spacecraft orbiting the moon officially have begun their science collection phase. During the next 84 days, scientists will obtain a high-resolution map of the lunar gravitational field to learn about the moon's internal structure and composition in unprecedented detail. The data also will provide a better understanding of how Earth and other rocky planets in the solar system formed and evolved.  |
