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

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.

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

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.

Researchers from the University of Chicago have identified a gene defect that causes the development of leukemia in children with Down syndrome. The discovery, scheduled for Advance Online Publication on Nature Genetics’s website on 12 August, could speed diagnosis and provide a new target for therapy.

Children with Down syndrome are 10 to 20 times as likely as unaffected children to develop leukemia. They most commonly develop a type known as acute megakaryoblastic leukemia (AMKL), wh

Rich and Inspiring Experience with NGC 300 Images from the ESO Science Data Archive
A series of wide-field images centred on the nearby spiral galaxy NGC 300, obtained with the Wide-Field Imager (WFI) on the MPG/ESO 2.2-m telescope at the La Silla Observatory, have been combined into a magnificent colour photo.

These images have been used by different groups of astronomers for various kinds of scientific investigations, ranging from individual stars and nebulae in NGC 300, to distant gal
