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.

Inspired by genetics, chemistry finally takes hold of its own code: Chemists can attain more complex supramolecular structures?

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

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

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

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.
