New Power Source Found in Water

EDMONTON, Alberta (UPI) -- Canadian scientists at the University of Alberta have discovered a new way to create electricity using water, the BBC reported Monday. "What we have achieved so far is to show that electrical power can be directly generated from flowing liquids in microchannels," said Professor Larry Kostiuk of the University of Alberta. The team says its "electrokinetic" battery could be further developed to provide a clean, non-polluting power source that could eventually drive small devices such as mobile phones. It is said to be the first new method of generating electricity in more than 150 years. The team created a glass block, one inch in diameter and 1.5 inches thick, containing about 400,000 to 500,000 individual channels. Because of a phenomenon called the electric double layer, when water flows through the 10-micron-diameter-wide channels, a positive charge is created at one end of the block and a negative charge at the other, just like a conventional battery.

Dreams Could Be Behind Infant Deaths

TORONTO, Aug. 5 (UPI) -- A new theory links sudden infant death syndrome to dreams, a Toronto newspaper reported Tuesday. The Australian scientist who offers the controversial theory in a new book on memory and dreams says a dreamlike state may return these babies to the environment of the womb, where their mothers supplied them with oxygen through their blood, the National Post said. "The reason we can't find the medical cause of death is because it's in the mind of the infant," said Dr. George Christos, a mathematician whose research has focused on neural networks. His theory was inspired by sleep research experiments in which adults stopped breathing when they dreamed of being underwater. Christos suggests making the sleeping environment less womb-like will reduce the risk of SIDS. "One could add some white noise, like a radio playing out of tune, for example," he says in his book Memory and Dreams: The Creative Human Mind.

Researchers Make Gene Discovery

CHICAGO (UPI) -- Researchers have found the exchange of genes between unrelated plant species, once considered forbidden by nature, seems to occur on a wide scale.The findings by Indiana University researchers, published in the British science journal Nature, surprised biologists who thought it was impossible, according to the Chicago Tribune. "I never expected this would happen," said Manyuan Long, a University of Chicago evolutionary geneticist. "Just two months ago I was teaching graduate students that this kind of horizontal gene transfer does not occur in higher organisms. Now I'm going to have to teach that it does." Charles Darwin said evolution means genetic changes occur in common ancestors and are passed down in a straight line called vertical gene transfer -- parents to child to grandchild. Horizontal gene transfer involves the exchange of genes from one species to another, possibly through a virus..

Quintessence = The Key to Antigravity

It would appear that science is discovering quantum mechanical nature to support an expanding universe and as well as antigravity. Let's encourage the next generation quantum engineers to develop personal antigravity limousines (i.e. pals) to jet us past the traffic jams. Accelerating Universe theory dispels dark energy.

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.

Scientists Discover Electrostatic Rotation

Researchers have identified a new physical phenomenon -- electrostatic rotation -- that in the absence of friction can lead to spin. This adds to the understanding of how the smallest building blocks in nature react to form solids, liquids and gases. University of California, Riverside, researchers first observed the electrostatic rotation in static experiments using three metal spheres suspended by thin metal wires. When a DC voltage was applied to the spheres they began to rotate until the stiffness of the suspending wires prevented further rotation. The researchers said experimental and theoretical work suggested the cumulative effect of electric charges would be an asymmetric force if the charges sitting on the surface of spheres were asymmetrically distributed but the experiments showed they could control the charge distribution by controlling the relative position of the spheres. Spin is used in quantum mechanics to explain phenomena at the nuclear, atomic and molecular domains for which there is no concrete physical picture.

Slow Light Easy To Create

University of Rochester researchers have developed a small device to create slow light -- at 127 miles per hour more than 5 million times slower than the normal speed of light. They say it could pave the way for slow light to move from a physical curiosity to a useful telecommunications tool. Researchers used a laser to "punch a hole" in the absorption spectrum of a ruby. To slow light the team used a quantum quirk called "coherent population oscillations" to create a gap in the frequencies of light a ruby absorbs. When the second beam, called the probe laser, shines into the ruby the probe beam has a different frequency than the first laser, and these offset frequencies interact, causing variations. Chromium ions respond to this new frequency of rhythmic highs and lows by oscillating in sympathy, which allows the probe laser to pass through the ruby more slowly than light otherwise would travel.
