High performance infrared camera based on type-II InAs/GaSb superlattices created (December 3, 2010) -- Researchers have created a new infrared camera based on Type-II InAs/GaSb superlattices that produces much higher resolution images than previous infrared cameras. ... > full story
New high-performance fiber created (December 3, 2010) -- Researchers have nanoengineered a new kind of fiber that could be tougher than Kevlar. ... > full story
Dark matter could transfer energy in the Sun (December 3, 2010) -- Researchers have studied the effects of the presence of dark matter in the Sun. According to their calculations, low mass dark matter particles could be transferring energy from the core to the external parts of the Sun, which would affect the quantity of neutrinos that reach Earth. ... > full story
Farmers slowed down by hunter-gatherers: Our ancestors' fight for space (December 3, 2010) -- Agricultural -- or Neolithic -- economics replaced the Mesolithic social model of hunter-gathering in the Near East about 10,000 years ago. One of the most important socioeconomic changes in human history, this socioeconomic shift, known as the Neolithic transition, spread gradually across Europe until it slowed down when more northern latitudes were reached. Newly published research details a physical model that can potentially explain how the spreading of Neolithic farmers was slowed down by the population density of hunter-gatherers. ... > full story
Blacker than black: NASA engineers developing material to help gather hard-to-obtain scientific measurements (December 3, 2010) -- Black is black, right? Not so, according to a team of NASA engineers now developing a blacker-than pitch material that will help scientists gather hard-to-obtain scientific measurements or observe currently unseen astronomical objects, like Earth-sized planets in orbit around other stars. ... > full story
'USB' interface for medical diagnosis? (December 3, 2010) -- Biomedical engineers have developed a plug-in interface for the microfluidic chips that will form the basis of the next generation of compact medical devices. They hope that the "fit to flow" interface will become as ubiquitous as the USB interface for computer peripherals. ... > full story
Distribution of gravitational wave sources predicted (December 3, 2010) -- A pair of neutron stars spiraling toward each other until they merge in a violent explosion should produce detectable gravitational waves. A new study predicts for the first time where such mergers are likely to occur in the local galactic neighborhood. ... > full story
Virtual biopsy may allow earlier diagnosis of brain disorder in athletes (December 3, 2010) -- In a study of ex-pro athletes, researchers found that a specialized imaging technique called magnetic resonance spectroscopy may help diagnose chronic traumatic encephalopathy, a disorder caused by repetitive head trauma that currently can only be definitively diagnosed at autopsy. ... > full story
Researchers find mathematical patterns to forecast earthquakes (December 3, 2010) -- Researchers in Spain have found patterns of behavior that occur before an earthquake on the Iberian peninsula. The team used clustering techniques to forecast medium-large seismic movements when certain circumstances coincide. ... > full story
Three-dimensional chemistry demonstrated by grinding powder (December 3, 2010) -- During the normal grinding of powders in a mortar, the powders can enter into chemical reactions with each other. This phenomenon has been known for years but only now it has become possible to transform in this way three-dimensional clusters of certain chemical compounds into other, also three-dimensional, clusters. The spectacularly easy reaction was conducted by scientists in Poland. The discovery was brought about by the development of a new method of creation of unique compounds that are precursors of nano zinc oxide – a material used, in particular, in modern electronics. ... > full story
Breakthrough chip technology lights path to exascale computing: Optical signals connect chips together faster and with lower power (December 3, 2010) -- IBM scientists have unveiled a new chip technology that integrates electrical and optical devices on the same piece of silicon, enabling computer chips to communicate using pulses of light (instead of electrical signals), resulting in smaller, faster and more power-efficient chips than is possible with conventional technologies. ... > full story
New microscopy tracks molecules in live tissue at video rate; scientists push SRS microscopy to new levels of spatial, temporal precision (December 2, 2010) -- A novel type of biomedical imaging, made possible by new advances in microscopy, is so fast and sensitive it can capture "video" of blood cells squeezing through capillaries. The new technique makes possible label-free chemical movies, with streaming footage at the subcellular level, catching video of proteins, lipids, and water within cells. ... > full story
