In one of the biggest advancements in fundamental transistor design, Intel Corporation revealed that it is using two dramatically new materials to build the insulating walls and switching gates of its 45 nanometer (nm) transistors. Hundreds of millions of these microscopic transistors -- or switches -- will be inside the next generation Intel® Core™ 2 Duo, Intel Core 2 Quad and Xeon® families of multi-core processors.

An analysis of 123 schools participating in the National Science Foundation (NSF) Math and Science Partnership (MSP) program shows improvements in student proficiency in mathematics and science at the elementary, middle- and high-school levels over a 3-year period.

The most recent data, for 2004-2005, show continued increases since the MSP program was established in 2002. Students showed the most significant improvements in mathematics proficiency, with a 13.7 percent increase for elementary, 6.2 percent increase for middle-school, and 17.1 percent increase for high-school students.

When it comes to body composition and fat distribution, a calorie is a calorie, regardless of whether it's controlled by diet alone or a combination of diet and exercise.

New research published in the Journal of Clinical Endocrinology & Metabolism reveals that dieting alone is equally effective at reducing weigh and fat as a combination of diet and exercise--as long as the calories consumed and burned equal out. The research also indicates that the addition of exercise to a weight-loss regimen does not change body composition and abdominal fat distribution, debunking the idea that specific exercises can reduce fat in targeted areas (e.g., exercise to reduce fat around a person's midsection).

"It's all about the calories," said Dr.

Thailand is doing the final preparations for the launch of its first earth observation satellite called THEOS into orbit in October, Thai Science and Technology Minister Yongyuth Yuthavong said Friday.

The THEOS project is expected to be completed in August or September and be launched into orbit in October as scheduled, the minister was quoted by Thai News Agency as saying.

The French company EADS Astrium, a leading European satellite producer, was contracted by the Geo-Informatics and Space Technology Development Agency (GISTDA) under Thai Ministry of Science and Technology in 2004 to build and deliver THEOS. Thai engineers working for the project have been trained in France.

National Hockey League players will stay cool on the ice thanks to research at Central Michigan University.

When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. NASA researchers have found a similar process at work in the atmosphere: tiny particles in the air called aerosols can cause a rippling effect on the climate thousands of miles away from their source region.

It's a mystery why the speed and complexity of evolution appear to increase with time. For example, the fossil record indicates that single-celled life first appeared about 3.5 billion years ago, and it then took about 2.5 billion more years for multi-cellular life to evolve.

The number of individuals with Parkinson's disease in 15 of the world's largest nations will double over the next generation, according to a study published in the January 30 issue of the journal Neurology. The study highlights the significant challenge facing countries with rapidly growing economies, particularly in Asia, many of which are ill prepared to meet this impending public health threat.

The growth in chronic diseases such as Parkinson's is one of the unfortunate byproducts of development. Economic growth and the corresponding improvements in health care and education are increasing the life expectancy of individuals in the developing world.

IBM has announced it has developed a long-sought improvement to the transistor -- the tiny on/off switch that serves as the basic building block of virtually all microchips made today.

Working with AMD and its other development partners Sony and Toshiba, the company has found a way to construct a critical part of the transistor with a new material, clearing a path toward chip circuitry that is smaller, faster and more power-efficient than previously thought possible.
