NIST Team Reports Method to Characterize New Insulating Materials for Microelectronics

Advance Should Speed Semiconductor Industry Search

Researchers from the Commerce Department’s National Institute of Standards and Technology (NIST) reported today they have developed methods for characterizing key structural features of porous films being eyed as insulators for the ultrathin metal wires that will connect millions of devices on future microprocessors and increase processor speed. The advance, reported today at the American Chemical Society’s national meeting

Why the hammerhead shark’s head is in the shape it’s in

A comprehensive examination of how the unique head and snout affects maneuverability and the role of its electrosensory function for seeking food along the ocean floor

Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. The dorso-ventrally compressed and laterally expanded pre-branchial head is an unmistakable diagnostic feature of the sphyrnid sharks. This unique head shape has been termed the cephalofoil in recognition of

Of mice and men: Deaf mouse leads scientists to new human hearing loss gene

In a powerful demonstration of how animal research can help humans, a pair of scientific teams is reporting the discovery of defects in a deafness gene in mice that led to the identification of similar genetic defects in people with hearing loss.

The findings, published in two new papers, may eventually lead to a screening test and therapy for families affected by one type of inherited hearing loss.

The discoveries also bring scientists closer to understanding the intricate choreo

LECs may be future of flat panel color displays

In the search for low-cost color displays that do not drain a computer’s battery, the polymer light-emitting electrochemical cell (LEC) may be the next answer to the problem, according to an international team of electrical engineers.

“The color-variable LEC can provide a solution to simple, low cost color displays,” Cheng Huang, graduate student in electrical engineering at Penn State told attendees today (Aug. 20) at the 224th American Chemical Society annual meeting in Boston.

Joint Genome Institute to sequence key African frog genome

DNA of Xenopus tropicalis will provide new clues to vertebrate development

In their continuing search for new clues to how human genes function and how vertebrates develop and evolve, researchers at the U.S. Department of Energy’s Joint Genome Institute (JGI) are gearing up to map the DNA of a diminutive, fast-growing African frog named Xenopus tropicalis .

Frogs have long been a favorite subject for biologists because their growth from eggs to tadpoles to

Studies define biochemical structure that keeps blood pressure low, bypass grafts open

A sort of biochemical scaffold for a compound that enables blood pressure to be low, heart bypass grafts to remain open and nerves to communicate has been identified by Medical College of Georgia researchers.

Researchers say identifying the framework for how these and other very positive health benefits occur should help them find ways to augment the benefits and identify new treatments for cardiovascular disease, which may result when the support structure falls apart.
