NanoClay… No Longer Just For Flower Pots

"Once you can control and manipulate nano-sized clay particles, then you have the ability to create smart materials by combining the structural support provided by the clay with the functionality of organic molecules, such as dye, enzymes, proteins and polymers," said Cliff Johnston, Purdue professor of agronomy and an environmental chemist. "That allows us to build the clay and the organic molecules into more complex structures."Nanometer-thick clay may yield groundbreaking technology.

Getting Closer to the Optical Chip

"The quantum dots sit at the bottom of quantum 'canyons,' or wells, Sargent explained. Electrons fall over the edge of the canyons and lose energy that is emitted as light when they reach bottom. Stabilizing molecules ensure that a steady flow of energy-losing, light-producing electrons falls into the wells."Optical Chips May Emerge from Quantum Canyons

The Internet Pays…

"INTERNET DELIVERS... To the surprise of many, the Internet is delivering on many of its supposedly discredited promises, BusinessWeek reported. The Internet is connecting far-flung people and businesses more tightly than ever. The value of networked business-to-business transactions now stands at $2.4 trillion, according to Forrester Research Inc. The Internet is helping companies slash costs, speeding the pace of innovation and jacking up productivity. The value of businesses using the Net to sharpen forecasting, keep inventories lean, and communicate instantaneously with suppliers could reach $450 billion a year by 2005. Spread across the economy in lower prices, that would add $4,500 annually to the average U.S. household's income -- more than three times the amount of President George W. Bush's 2001 tax cut, according to BusinessWeek."

Talk About ‘Far Out!’

"FINDING ALIEN MESSAGES... Two University of Hawaii physicists say the reason we're not getting messages or signals from alien civilizations is that such communication is disguised and indistinguishable from background noise. Walter Simmons and Sandip Pakvasa say messages sent by this method could be criss-crossing our galaxy without us ever knowing. If a signal -- a stream of photons -- comes from a single source, its origin can always be determined by measuring the direction of recoil of a detector struck by the photons. The physicists say the way around this is the signaler splits the message into two parts, so photons are sent in opposite directions to mirrors located far from the home planet. The mirrors redirect the signals to the intended receiver, who recombines the photons to reconstruct the message. If the image is tiny enough, Heisenberg's uncertainty principle -- which limits the amount of information that can ever be known about a microscopic particle -- means measuring the position of the photons makes it impossible to gain accurate information about the direction in which they are traveling. It also would be impossible to detect the message at all without extremely sophisticated technology. To recombine the beams and recreate the message you would need to detect the arrival time of the photons extremely accurately to identify pairs of photons split by the sender."
