NASA Curiosity Mars rover installing smarts for driving (August 10, 2012) -- NASA's Mars rover Curiosity will spend its first weekend on Mars transitioning to software better suited for tasks ahead, such as driving and using its strong robotic arm. The rover's "brain transplant," which will occur during a series of steps Aug. 10 through Aug. 13, will install a new version of software on both of the rover's redundant main computers. This software for Mars surface operations was uploaded to the rover's memory during the Mars Science Laboratory spacecraft's flight from Earth. ... > full story

Quantum cryptography theory has a demonstrated security defect (August 10, 2012) -- Researchers have just demonstrated the incompleteness and limit of the security theory in quantum key distribution. The present theory cannot guarantee unconditional security. ... > full story

Stabilizing shell effects in heaviest elements directly measured (August 10, 2012) -- An international research team has succeeded in directly measuring the strength of shell effects in very heavy elements. The results provide information on the nuclear structure of superheavy elements, thus promising to enable drastically improved predictions concerning the location and extension of the island of stability of superheavy elements. ... > full story

Rooting out rumors, epidemics, and crime -- with math (August 10, 2012) -- Scientists have developed an algorithm that can identify the source of an epidemic or information circulating within a network, a method that could also be used to help with criminal investigations. ... > full story

Project Morpheus vehicle experiences hardware component failure (August 10, 2012) -- NASA's prototype Morpheus lander crashed in a test flight on Thursday (Aug. 9, 2012), at Kennedy Space Center in Florida. The vehicle lifted off the ground and then experienced a hardware component failure. This failure prevented the vehicle from maintaining stable flight.
