| NASA's OPALS to beam data from space via laser Posted: 11 Jul 2013 12:14 PM PDT NASA will use the International Space Station to test a new communications technology that could dramatically improve spacecraft communications, enhance commercial missions and strengthen transmission of scientific data.  |
| Writing computer programs using ordinary language: Systems convert ordinary language to code Posted: 11 Jul 2013 10:56 AM PDT Researchers have demonstrated that, for a few specific tasks, it's possible to write computer programs using ordinary language rather than special-purpose programming languages. The work may be of some help to programmers, and it could let nonprogrammers manipulate common types of files -- like word-processing documents and spreadsheets -- in ways that previously required familiarity with programming languages.  |
| Solar tsunami used to measure Sun's magnetic field Posted: 11 Jul 2013 08:34 AM PDT A solar tsunami observed by NASA's Solar Dynamics Observatory and the Japanese Hinode spacecraft has been used to provide the first accurate estimates of the Sun's magnetic field.  |
| Posted: 11 Jul 2013 08:34 AM PDT Forget fingerprints or iris recognition, the next big thing in biometrics will be a thermal imaging scan that maps the blood vessels under the skin of your face for instantaneous face recognition that would be almost impossible to spoof.  |
| Stellar monsters do not collide: No hope for a spectacular catastrophe Posted: 11 Jul 2013 07:31 AM PDT One might expect that collisions between the remains of monstrous stars, with masses reaching 200-300 times that of our Sun, would be among the most spectacular phenomena in the Universe. Perhaps they are, but we will unfortunately probably never have the chance to find out. Astrophysicists have discovered that the first such collisions will not occur until billions of years from now.  |
| Trapping T-rays for better security scanners Posted: 11 Jul 2013 07:29 AM PDT Medical diagnostic and security scanners with higher sensitivity could result from new research into detecting T-rays (terahertz waves).  |
| Hubble finds a true blue planet: Giant Jupiter-sized planet located 63 light-years away Posted: 11 Jul 2013 07:28 AM PDT Astronomers using NASA's Hubble Space Telescope have deduced the actual visible-light color of a planet orbiting another star 63 light-years away. If seen directly the planet, known as HD 189733b, would look like a "deep blue dot," reminiscent of Earth's color as seen from space.  |
| Race for new temperature definition: Most accurate measurement yet of Boltzmann constant Posted: 11 Jul 2013 05:48 AM PDT Scientists have performed the most accurate measurement yet of the Boltzmann constant. While the impact of such an achievement is not immediately obvious, the measurement could revolutionize the way we define temperature, replacing the standard method that has been used for over 50 years.  |
| What will the future hold for cyborgs, the fusion of humans and machines? Posted: 11 Jul 2013 05:41 AM PDT People composed of biotechnology are cyborgs, an amalgam of human being and technology. What direction are human beings, or should I say cyborgs, headed in?  |
| Dye-sensitized solar cells rival conventional cell efficiency Posted: 10 Jul 2013 11:18 AM PDT Dye-sensitized solar cells rival conventional photovoltaic devices by getting an efficiency boost up to 15 percent thanks to a new solid-state version of the perovskite light harvester device and a two-step fabrication process developed by scientists in Switzerland.  |
