| Solar corona revealed in super-high-definition Posted: 20 Jul 2012 04:55 PM PDT Astronomers have just released the highest-resolution images ever taken of the Sun's corona, or million-degree outer atmosphere, in an extreme-ultraviolet wavelength of light. The 16-megapixel images were captured by NASA's High Resolution Coronal Imager, or Hi-C. The Hi-C telescope provides five times more detail than the next-best observations by NASA's Solar Dynamics Observatory.  |
| Radiation damage bigger problem in microelectronics than previously thought Posted: 20 Jul 2012 04:54 PM PDT The amount of damage that radiation causes in electronic materials may be at least 10 times greater than previously thought. That is the surprising result of a new characterization method that uses a combination of lasers and acoustic waves to that allows scientists to peer through solid materials to pinpoint the size and location of detects buried deep inside with unprecedented precision.  |
| Highly transparent solar cells for windows that generate electricity Posted: 20 Jul 2012 10:57 AM PDT Researchers have developed a new transparent solar cell that is an advance toward giving windows in homes and other buildings the ability to generate electricity while still allowing people to see outside.  |
| Better security for web and mobile applications Posted: 20 Jul 2012 10:57 AM PDT When it comes to computer security, who checks the checker? Computer scientists have developed a new tool that could lead to increased security and enhanced performance for commonly used web and mobile applications. Called RockSalt, the clever bit of code can verify that native computer programming languages comply with a particular security policy.  |
| River networks on Saturn's largest moon, Titan, point to a puzzling geologic history Posted: 20 Jul 2012 07:35 AM PDT New findings suggest the surface of Saturn's largest moon may have undergone a recent transformation. For many years, Titan's thick, methane- and nitrogen-rich atmosphere kept astronomers from seeing what lies beneath. Saturn's largest moon appeared through telescopes as a hazy orange orb, in contrast to other heavily cratered moons in the solar system. Researchers have now analyzed images of Titan's river networks and determined that in some regions, rivers have created surprisingly little erosion.  |
| Stone Age tools help to streamline modern manufacturing Posted: 20 Jul 2012 07:35 AM PDT Innovative research uses laser microscopes to explore how stone tools were used in prehistory, and the process has helped streamline surface measurement techniques for modern manufacturers.  |
| 'Seeds' of massive black holes found at the center of the Milky Way galaxy Posted: 20 Jul 2012 05:30 AM PDT Many galaxies contain enormous amounts of molecular gas in small areas near their nuclei. Highly condensed molecular gas is a birthplace of lots of stars. Moreover, it is considered to closely relate to activities of galactic nuclei. Therefore, it is important to investigate the physical state and chemical properties of molecular gas at galaxy centers through observation. To obtain detailed observation data, it is best to survey the center of the Milky Way Galaxy in which our solar system exists.  |
| Posted: 18 Jul 2012 07:14 AM PDT Molecular sensors based on nanoholes in metallic films are shown to be ideal for medical diagnosis.  |
