Wed, 14 Nov 2007 09:00:00 GMT A NASA satellite is expected to help scientists resolve wide-ranging predictions about the coming solar cycle peak in 2012 and its influence on Earth's warming climate. Solar cycles, which span an average of 11 years, are driven by the amount and size of sunspots present on the sun's surface, which modulate brightness from the X-ray to infrared portion of the electromagnetic spectrum. more

Mon, 12 Nov 2007 15:00:00 GMT Where do the realms of quantum mechanics and classical physics begin to overlap? It's a long-argued question of philosophical interest and practical importance. Now the world's smallest double slit experiment, performed at Lawrence Berkeley National Laboratory's Advanced Light Source and using as "slits" the two proton nuclei of a hydrogen molecule, has shown that quantum particles start behaving in a classical way on a scale as small as a single hydrogen molecule. more

Sat, 10 Nov 2007 18:00:00 GMT Computer scientists have watched malicious traffic on the Internet evolve from childish pranks to a billion-dollar "shadow industry" in the last decade, and the profession has largely been one step behind the bad guys. Viruses, phishing scams, worms and spyware are only the beginning, according to one computer science specialist. more

Wed, 07 Nov 2007 09:00:00 GMT Scientists have developed a new means of extracting and interpreting data from the human genome that is more powerful and more economical than methods currently employed. The new technology, called selective resequencing, promises to be a boon to many kinds of research, including efforts to comb vast stretches of the genome for mutant genes implicated in major diseases such as cancer and schizophrenia. more

Mon, 05 Nov 2007 12:00:00 GMT Engineers have successfully tested a groundbreaking new magnet design that could literally shed new light on nanoscience and semiconductor research. Magnet engineers worldwide have been trying to solve the problem of creating a magnet with side access at the midsection, but they have met with little success in higher fields. more

Mon, 05 Nov 2007 18:00:00 GMT Physicists have performed computer simulations that show how electrons become one thousand times more massive in certain metal compounds when cooled to temperatures near absolute zero. The models may provide new clues as to how superconductivity works and how new superconducting materials could be fabricated. The researchers describe how electrons interact with other particles in these compounds to morph into a fluid of "heavy quasiparticles" or a "heavy fermion fluid."more

Sun, 04 Nov 2007 00:00:00 GMT Electrical engineers have developed the world's most complex 'phased array' -- or radio frequency integrated circuit. This advance is expected to find its way into US defense satellite communication and radar systems. In addition, the innovations in this chip design will likely spill over into commercial applications, such as automotive satellite systems for direct broadcast TV, and new methods for high-speed wireless data transfer

Thu, 01 Nov 2007 09:00:00 GMT Specifically aimed, "stereotactic" radiation may be as good as surgery -- and in some cases, even better -- in treating benign but potentially devastating brain tumors called nonacoustic schwannomas, according to a study by radiation oncologists. more

Thu, 25 Oct 2007 18:00:00 GMT In a major feat of nanotechnology engineering researchers have demonstrated a laser with a wide-range of potential applications in chemistry, biology and medicine. Called a quantum cascade laser nanoantenna, the device is capable of resolving the chemical composition of samples, such as the interior of a cell, with unprecedented detail. The new laser could lead to ultrahigh resolution microscopes for chemical imaging in biology and medicine.more

Mon, 22 Oct 2007 21:00:00 GMT A scientific mystery that stumped chemists for nearly seven decades has now been solved. ADP, like many crystals, exhibits an electrical phenomenon known as ferroelectricity, but it can also display antiferroelectric properties. New research points to the design of materials with both ferroelectric and antiferroelectric properties. This may lead to the development of more powerful computer memories and lasers. more
