| Rover's laser instrument zaps first Martian rock Posted: 19 Aug 2012 01:52 PM PDT NASA's Mars rover Curiosity fired its laser for the first time on Mars, using the beam from a science instrument to interrogate a fist-size rock called "Coronation." The mission's Chemistry and Camera instrument, or ChemCam, hit the fist-sized rock with 30 pulses of its laser during a 10-second period. Each pulse delivers more than a million watts of power for about five one-billionths of a second.  |
| Researchers make quantum processor capable of factoring a composite number into prime factors Posted: 19 Aug 2012 12:37 PM PDT Computing prime factors may sound like an elementary math problem, but try it with a large number, say one that contains more than 600 digits, and the task becomes enormously challenging and impossibly time-consuming. Now, a group of researchers has designed and fabricated a quantum processor capable of factoring a composite number -- in this case the number 15 -- into its constituent prime factors, 3 and 5. Factoring very large numbers is at the heart of cybersecurity protocols, such as the most common form of encoding, known as RSA encryption.  |
| Posted: 19 Aug 2012 12:37 PM PDT Nature proves every day that it is both complex and efficient. Organic chemists are envious of it; their conventional tools confine them to simpler achievements. These limitations could become a thing of the past. New research offers a new kind of code to chemists, allowing them to access new levels of complexity.  |
| 'DNA wires' could help physicians diagnose disease Posted: 19 Aug 2012 12:37 PM PDT Scientists have found that Mother Nature uses DNA as a wire to detect the constantly occurring genetic damage and mistakes that can result in diseases like cancer. DNA wires are potentially useful in identifying people at risk for certain diseases.  |
| A new route to dissipationless electronics Posted: 19 Aug 2012 12:36 PM PDT A team of researchers has demonstrated a new material that promises to eliminate loss in electrical power transmission. The surprise is that their methodology for solving this classic energy problem is based upon the first realization of a highly exotic type of magnetic semiconductor first theorized less than a decade ago - a magnetic topological insulator.  |
| New space-age insulating material for homes, clothing and other everyday uses Posted: 19 Aug 2012 12:34 PM PDT A major improvement in the world's lightest solid material and best solid insulating material may put more of this space-age wonder into insulated clothing, refrigerators with thinner walls that hold more food, building insulation and other products.  |
