 Curiosity spots asteroids from the surface of Mars Greenbelt, Md. (UPI) Apr 25, 2013 - For the first time, NASA's Curiosity rover has captured images of an asteroid from the surface of Mars - two of them, in fact. The imagery recorded by Curiosity and beamed back to Earth feature Ceres and Vesta, two of the largest asteroids in the asteroid belt that runs between between Mars and Jupiter. This Curiosity first was also a bit of a coincidence, as the SUV-sized rover had ai ... more |  |
 Pentagon scientists show off life-size robot Washington (AFP) April 23, 2014 - US Defense Secretary Chuck Hagel got a first-hand look at a life-size robot Tuesday that resembles Hollywood's "Terminator," the latest experiment by the Pentagon's hi-tech researchers. But unlike the cinematic version, the hulking Atlas robot is designed not as a warrior but as a humanitarian machine that would rescue victims in the rubble of a natural disaster, officials said. The 6-f ... more |  |

 Economics = MC2 A portrait of the modern physics startup Washington DC (SPX) Apr 24, 2014 - For much of the 20th century, many of the technological innovations that drove U.S. economic growth emerged from "idea factories" housed within large companies - research units like Bell Labs or Xerox PARC that developed everything from the transistor to the computer mouse. In recent decades, however, many large high-tech companies have eliminated in-house research programs, turning inste ... more |  |

Physicist demonstrates dictionary definition was dodgy Brisbane, Australia (SPX) Apr 24, 2014 - It is the defining moment that demonstrates a QUT physicist was correct in pointing out a 99-year-old mistake to one of the world's most authoritative dictionaries. QUT Senior Lecturer in Physics, Dr Stephen Hughes, sparked controversy over how a humble siphon worked when he noticed an incorrect definition in the prestigious Oxford English Dictionary. In 2010, eagle-eyed Dr Hughes sp ... more |  |
A new key to unlocking the mysteries of physics? Quantum turbulence New York NY (SPX) Apr 24, 2014 - The recent discovery of the Higgs boson has confirmed theories about the origin of mass and, with it, offered the potential to explain other scientific mysteries. But, scientists are continually studying other, less-understood forces that may also shed light on matters not yet uncovered. Among these is quantum turbulence, writes Katepalli Sreenivasan, an NYU University Professor, in a spec ... more |  |

"The F-35 will provide a major boost to the Australian Defence Force's ... more |  |
 US Military hopes AI autopilot can replace flight crews Moscow (Voice of Russia) Apr 25, 2014 - The US Defense Department is developing a method of autopilot that may allow the military to reduce air flight crews to a fraction of their current size. This announcement comes after officials worried that a reduced military would be less effective. The Defense Advanced Research Projects Agency (DARPA), the Pentagon's research and development department said Tuesday that, over the next 50 ... more |  |
Lockheed Martin Demonstrates Enhanced Ground Control System and Software for Small Unmanned Aircraft Owego NY (SPX) Apr 25, 2014 - Lockheed Martin's Group 1 family of unmanned aircraft systems is migrating to enhanced automation capabilities using its Kestrel "Fly Light" flight control systems and industry-leading mobile Ground Control Station (mGCS) software.

 Steering chemical reactions with laser pulses Vienna, Austria (SPX) Apr 25, 2014 - Usually, chemical reactions just take their course, much like a ball rolling downhill. However, it is also possible to deliberately control chemical reactions: at the Vienna University of Technology, molecules are hit with femtosecond laser pulses, changing the distribution of electrons in the molecule. This interaction is so short that at first it does not have any discernable influence on the ... more |  |
