- High-frequency cryocooler is tiny, cold and efficient
02-15-2007 · EurekAlert!
A new cryogenic refrigerator has been demonstrated at NIST that operates at twice the usual frequency, achieving a long-sought combination of small size, rapid cooling, low temperatures and high efficiency. The cryocoooler could be used to chill instruments for space and military applications, and is a significant step towards even smaller, higher-frequency versions for integrated circuits and microelectromechanical (MEM) systems.

- Developing uses for sugar-cane bagasse: Biotechnology applied to the paper industry
11-13-2006 · EurekAlert!
Sugar-cane bagasse is a fibrous waste-product of the sugar refining industry, which can be recycled as a raw material for paper manufacture. IRD researchers have elaborated a new bioprocess that transforms the bagasse into paper pulp and also produces an industrially useful enzyme, laccase. The process is based on the metabolism of a filamentous fungus. Preliminary laboratory trials show that this integrated bioprocess can be adapted to other potential fibre-yielding materials, opening up promising applications for the paper industry.

- Zeroing in on the brain's speech 'receiver'
06-20-2007 · EurekAlert!
A particular resonance pattern in the brain's auditory processing region appears to be key to its ability to discriminate speech, researchers have found. They found that the inherent rhythm of neural activity called "theta band" specifically reacts to spoken sentences by changing its phase. The researchers also noted that the natural oscillation of this frequency provides further evidence that the brain samples speech segments about the length of a syllable.
