A Glow In The Martian Night - SpaceDaily  LeftLight produced on the night side of Mars may be due to chemical reactions occurring in the atmosphere; when one atom of nitrogen combines with one atom of oxygen it forms a new molecule called nitric oxide. When it recombines, it emits one photon. This photon may have several different wavelengths, but the wavelengths of these photons are quite typical of this nitric oxide molecule.  "Our paper is about light that was discovered on the night side of Mars. Up to now, there has been no detection of this natural light, or "air glow." It has been seen on the day side of Mars by Mariner 6, 7 and 9 in the ultraviolet, but there were no observations of the night side. How is this kind of light produced? One way is through chemically produced emissions. That occurs in the atmosphere of the Earth, and has been seen in the atmosphere of Venus, and we have discovered for the first time it happening in the atmosphere of Mars. 
MRAM Rising As Nano-Memory - SpaceDaily  In the next decade, the leading method of data storage could be nanotechnology-based magnetic RAM or MRAM, which is expected to grow to a market of $2.1 billion by 2008 and $16.1 billion by 2012. b\Because MRAM can be directly programmed in a few nanoseconds, it is extremely fast compared with Flash, which takes milliseconds to program and also requires a separate erase cycle, Tehrani said. In addition, while it can be as fast as SRAM, MRAM can in theory achieve higher density, since MRAM only has one transistor per cell while SRAM uses six to achieve its high speed.    

 Climate: Low-Carbing The Atmosphere - SpaceDaily  Left:  Sweeping it under the ground should do the trick for a century or two.  Carbon sequestration has become the leading weapon in the U.S. government's arsenal against climate change. There is a hoary saying in the business world that is easier to save a dollar than to make a dollar, but this advice seems to be cheerfully ignored in the U.S. climate policy arena. There, a technology-investment fix is being promoted over a regulatory approach that restricts carbon emissions - that is, not emitting the greenhouse gas in the first place. About $110 million in public and private funds would be invested in 65 carbon sequestration projects around the country.
