Low-Cost Multi-point Interactive Whiteboards Using the Wiimote Since the Wiimote can track sources of infrared (IR) light, you can track pens that have an IR led in the tip. By pointing a wiimote at a projection screen or LCD display, you can create very low-cost interactive whiteboards or tablet displays. Since the Wiimote can track upto 4 points, up to 4 pens can be used. It also works great with rear-projected displays.

The human hand is an amazing machine that can pick up, move and place objects easily, but for a robot, this "gripping" mechanism is a vexing challenge. Opting for simple elegance, researchers from Cornell University, University of Chicago, and iRobot have bypassed traditional designs based around the human hand and fingers, and created a versatile gripper using everyday ground coffee and a latex party balloon.

A technique for creating a new molecule that structurally and chemically replicates the active part of the widely used industrial catalyst molybdenite has been developed by researchers with the U.S.

"And what if science becomes - or has become - lower-yield? Is that a reason to reconsider funding policies? Rationally, looking at the cost-benefit may already have effects on resource and funding allocations. Is it unreasonable to assume that science will continue to produce large, demonstrable advances and insights of the size and importance of the major breakthroughs?"

I think the comments under the linked article sufficiently refute it.

Driving distractions such as cell phones and other electronic devices cause as much as 25% of all U.S. car accidents, researchers at the Governors Highway Safety Association have found, WinBETA notes. A major finding was that being distracted was the cause of 15 to 25% of all accidents, ranging from minor property damage to death. Their findings suggest that distracted driving accidents be reported in accident reports to assist in evaluating distracted driving laws and programs. They propose creating low-cost roadway measures that alert motorists when they are drifting out of their driving lane. They also propose that all cell phones be banned on the road, even hands-free versions. In another report by The New York Times, police in Syracuse and Hartford have handed out nearly 20,000 tickets for illegal use of a phone while driving - either for texting or use of a handheld phone. According to the federal government, these efforts have had the desired effect: distracted driving has fallen sharply. Their research shows that drivers talking on a phone are four times as likely to get into a crash as those not on a phone, and that the risks for motorists who text are at least twice as high. In Syracuse, handheld cellphone use and texting have each fallen by one-third. In Hartford, handheld cellphone use by drivers fell 57 percent while texting fell by 75 percent, the Times reports.

ScienceDaily (June 28, 2011) - Inkjet printers, a low-cost technology that in recent decades has revolutionized home and small office printing, may soon offer similar benefits for the future of solar energy.

Researchers have developed a water-purifying filter that makes the process more than 80,000 times faster than existing filters. The key is coating the filter fabric -- ordinary cotton -- with nanotubes and silver nanowires, then electrifying it. The filter uses very little power, has no moving parts and could be used throughout the developing world.
