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

Sat, 20 Oct 2007 12:00:00 GMT The winner of the Solar Decathlon -- a competition between 20 college and university teams to compete in 10 contests and design, build, and operate the most attractive and energy-efficient solar-powered home -- was the German University Technische Universität Darmstadt. The Solar Decathlon's homes are zero-energy, yield zero carbon, and include the latest high-tech solutions and money-saving benefits to consumers, without sacrificing comfort, convenience, and aesthetics.more

Wed, 17 Oct 2007 06:00:00 GMT Scientists have found that the f and m type plant thioredoxins previously thought to be localized only in chloroplasts are found in other, nonphotosynthetic, tissues, where they may have multiple functions. They have now established the presence of these redox proteins in tissues other than the chloroplast.more
