| Posted: 08 Oct 2012 01:18 PM PDT Whether it's a wedding, birthday party or other celebration, these days the chances are you'll have your camcorder with you to record the great occasion. But we often forget to bring the data cable along with us, so despite promising the hosts to transfer the images to their computer the morning after, we hardly ever do. |
| Deep cleaning with carbon dioxide Posted: 08 Oct 2012 01:18 PM PDT In server components, hard disks, or clock mechanisms, the smallest impurities lead to malfunctions and short circuits; in optical components such as lenses, they impair quality because they scatter light; in threaded holes, they cause mechanical failure. The phenomena of progressive miniaturization and ever more complex components are presenting the manufacturers of cleaning technologies and tools with big challenges. However, cleaning with carbon dioxide (CO2) has proven itself an effective means of removing extremely fine dirt particles. |
| How pulsars slow down with age Posted: 08 Oct 2012 06:15 AM PDT Researchers have developed a model which explains how the spin of a pulsar slows down as the star gets older. A pulsar is a highly magnetized rotating neutron star which was formed from the remains of a supernova - an explosion which happens after a massive star runs out of nuclear fuel. A pulsar emits a rotating beam of electromagnetic radiation, rather like that of a lighthouse. This beam can be detected by powerful telescopes when it points towards and sweeps past the Earth. |
| Liquorice offers clue to cleaner medical implants Posted: 08 Oct 2012 06:15 AM PDT A new coating utilizing nanotechnology will allow surgeons to sterilize medical devices that contain biological components. A nanotech material containing an extract from liquorice can be used to sterilize and protect medical devices and implants which include biological components, and protects these functional bio-components during the sterilization process. |
| Paving the way for commercial fusion power plants Posted: 08 Oct 2012 06:15 AM PDT Latest results from the Joint European Torus (JET) fusion device are giving researchers increasing confidence in prospects for the next-generation ITER project, the international experiment that is expected to pave the way for commercial fusion power plants. Operation with a new lining inside JET has demonstrated the suitability of materials for the much larger and more powerful ITER device. |
| New surveys peer through dust to reveal giant supermassive black holes Posted: 08 Oct 2012 06:15 AM PDT Scientists have used cutting-edge infrared surveys of the sky to discover a new population of enormous, rapidly growing supermassive black holes in the early Universe. The black holes were previously undetected because they sit cocooned within thick layers of dust. The new study has shown however that they are emitting vast amounts of radiation through violent interactions with their host galaxies. |
| Catalytic converters like it hot Posted: 08 Oct 2012 05:29 AM PDT Researchers have clarified what it is the required operating temperatures of catalytic converters in cars depend on. |
