Mechanisms that cause the solar wind had baffled scientists for decades, but were revealed in observations by a Japanese satellite called Hinode WASHINGTON — The solar wind, which whips off the sun and blows past Earth and through the solar system, is unleashed by powerful magnetic waves in electrically charged gas around the sun, scientists said on Thursday. The mechanisms that cause the solar wind had baffled scientists for decades, but were revealed in observations by a Japanese satellite called Hinode orbiting Earth, the scientists said in research published in the journal Science.

The team from Taiwan, where the world's first genetically engineered fluorescent fish were created in 2003, injected a protein extracted from jelly fish into the nucleus of a pig embryo to breed three male transgenic pigs. It is hoped that the pigs would eventually enable reserachers to trace the development of tissues when stem cells are used to repair damaged organs. Professor Wu dismissed concerns that the technology could endanger the ecosystem.

The scientists from the University of Alberta and Dalhousie University say the laser measures aerosols, clouds, water vapour and temperatures. The laser will be sent into orbit on a space shuttle in 2007. It will then be pointed at Mars in hopes of determining whether the planet really did have bodies of water billions of years ago.

Devices that control electrical current flow are known as transistors. Computers operate with millions of transistors, set onto silicon microchips, that switch current on and off to represent binary digits.
Where today's transistors require about one million electrons to switch a current, Dr. Wolkow and his team say they have managed to switch the current through a molecule using a single electron. That means the flow can be changed much faster and using far less power.

The lens can eliminate the thick glass used in optical lens, and has the potential to eliminate distortion caused by conventional zoom mechanisms. The inventor of the lens, Tigran Galstian of Laval University, said that the lens could dramatically increase the quality of photos taken by small cameras such as cellphone cameras. "Right now we're guessing what industry needs and we'd love to work with them on what they really want," he said.

One of the discoverers, Ted Sargent, said that the material "catches" solar energy and a layer of it could be applied to any device, much like paint on a wall. It can convert up to 30 per cent of the sun's power into usable electricity, compared to plastic solar cells that capture only about six per cent.

Tuesday Jul 1, 2003 cc Inca secrets may lie in knots The Inca shared records with the conquistadores; they may have drawn from a three-dimensional language
The "lost city" Machu Picchu represents a mystery to archeologists. Part of the reason is the absence of a written Inca language, which could be resolved if knotted strings are shown to be more than accounting tools.
Until now, khipu (also spelled quipu) were widely thought to be little more than accounting tools, with various knot combinations representing totals like beads on an abacus. Because no one has ever been able to decipher the knot patterns, many scholars have said khipu were the haphazard concoctions of individuals, and were not ''recording machines'' designed to be read universally. Some scholars have even dismissed khipu as mere ''reminders'' for their owners to do tasks or recite stories, like string tied around a person's finger.
Evidence suggesting khipu could be interpreted by anyone trained to read them came two weeks ago after hundreds of hours of painstaking analysis of 32 khipu discovered in 1997 among 225 mummy bundles in a rock overhang in northern Peru. ....Mr. Urton has also begun arguing that khipu incorporated a binary code capable of conveying at least 1,536 pieces of information. For comparison, the earliest forms of Sumerian cuneiform had 1,300-1,500 signs, and Mayan and Egyptian hieroglyphics 600-800.
