Commentary: Is Bush's Moon-to-Mars Vision Dimming? - Space.com  Like his father's proposal to go to Mars, President George W. Bush's grand space exploration vision appears to be on the verge of being scuttled well before launch. Despite its goal of refocusing NASA, the vision's potential to inspire dreams and garner new funds is largely evaporating. The devil is in the lack of details. Critics charged the plan, as it were, lacked specifics and the costs could not be easily estimated.
Quantum Computers Are A Quantum Leap Closer, Say Purdue Physicists - SpaceDaily  Left:  As part of an effort to make superpowerful quantum computers, Purdue University researchers have created "quantum dots" in a semiconducting material known as gallium arsenide. The quantum dots (the two small circular areas shown adjacent to one other in the center of the image) are puddles of about 40-60 electrons. Together the dots can form part of transistors in which the electrons' spin, a quantum mechanical property, could be harnessed to make logic gates for next-generation computer chips. Each dot measures only about 180 nanometers (billionths of a meter) in diameter about 5,000 of them could stretch across the width of a grain of sand. (Illustration by Albert Chang, Duke University Department of Physics)  By linking a pair of tiny "puddles" of a few dozen electrons sandwiched inside a semiconductor, researchers have enabled these two so-called "quantum dots" to become parts of a transistor.

Invasion Of The Traffic Cones - SpaceDaily  It sounds like a driver's worst nightmare. Herds of traffic cones swarm onto a highway, closing down lanes and slowing the traffic. But it's no bad dream. The robotic road markers have been developed by Shane Farritor, a roboticist at the University of Nebraska-Lincoln, in a bid to help reduce the $100 billion per year that the Department of Transportation estimates is lost to the US economy through accidents and delays caused by highway lane closures reports New Scientist. The self-propelled markers take the form of robotic three-wheeled bases for the brightly coloured barrels.
