NASA To Test Laser Communications With Mars Spacecraft - Space.com  The $300 million NASA experiment, if successful, will connect robotic spacecraft at Mars with scientists back on Earth via a beam of light. The 5-watt laser NASA plans to test at Mars by the end of the decade is expected to transmit data at rates nearly 10 times faster than any existing interplanetary radio communications link. The difference, NASA officials said, will be comparable to moving from a dial-up modem to a broadband Internet connection.

We discovered many DNA sequences, originally counted as non-functioning segments, actually do encode active genes."  

Sandwich Clusters May Improve Magnetic Memory Storage - SpaceDaily  Left:  "Sandwich clusters” consist of alternating layers of metal atoms and organic molecules. Clusters can be several nanometers (billionths of a meter) in length, depending on the number of layers. Clusters display different magnetic behaviors than regular bulk metals.  A new type of molecular magnet known as a "sandwich cluster" is being studied under a joint research collaboration between the U.S. Department of Energy's Argonne National Laboratory, the University of Chicago and Keio University in Japan. These molecular magnets could be useful for magnetic storage or spintronics, developing technologies that could enable computers to have ultra-small storage capabilities with faster and more energy-efficient systems.
