Rising Temperatures Will Lead To Loss Of Trout Habitat In Southern App
USDA Forest Service research projects that between 53 and 97 percent of natural trout populations in the southern Appalachians could disappear due to the warmer temperatures predicted under two different global climate circulation models. In an article published Oct. 2 in the online version of the Transactions of the American Fisheries Society, Patricia Flebbe, research biologist at the FS Southern Research Station unit in Blacksburg, Va., maps out trout habitat in a future, warmer climate. Doping Technique Brings Nanomechanical Devices Into The Semiconductor
With the help of a device capable of depositing metals an atom at a time in the materials used in computer chips, engineers have successfully blended modern semiconductor technology and nanomachines. Loosen Up, DNA: Leukemia Gene Changes Genetic Packaging
A signaling system involved in many forms of leukemia and lymphoma is more powerful than scientists have thought, exerting control over our genes by affecting whole swaths of chromosomes in global fashion. The findings come from a study where mutant fruit flies with either red or white eyes tell the tale of a cellular signaling system known as JAK/STAT. The finding meshes nicely with current trends in cancer drug research. Cells From Amniotic Fluid Used To Tissue-engineer A New Tracheahttp://
Sight Can Recover Quickly In Amblyopia
New research findings led by Thomas Krahe and Ary S. Ramoa of Virginia Commonwealth University School of Medicine offer two pieces of good news for treating children with amblyopia. First, the researchers have found evidence that the neural wiring in the brain's visual system is not dismantled by visual deprivation -- for example, due to a cataract -- during what is known as the "critical period"of vision development. Rather, the wiring is merely deactivated, capable of being rapidly reactivated when vision is restored. Neuroscientists store information in isolated brain tissue; possible b
For the first time, neuroscientists have created stimulus-specific sustained activity patterns in brain circuits maintained in vitro. Rapid Response To Avian Flu Threat
An interdisciplinary team of researchers led by Yanbin Li, professor of biological engineering in the University of Arkansas Division of Agriculture, has developed a portable biosensor for in-field, rapid screening of avian influenza virus. Nanotech Clay Armour Creates Fire Resistant Hard Wearing Latex Emulsio
Researchers have found a way of replacing the soap used to stabilize latex emulsion paints with nanotech sized clay armour that can create a much more hard-wearing and fire-resistant paint. Children With Intracranial Ependymoma Can Avoid Damage-causing Radioth
Use of chemotherapy to treat children with intracranial ependymoma avoids or delays the need for use of radiotherapy which can potentially cause serious damage to the child's nervous system, without compromising chances of survival. Intracranial ependymomas are tumours which mostly develop around the lining of the cerebral ventricles. Small Changes In 1918 Pandemic Virus Knocks Out Transmission
Experts at the Centers for Disease Control and Prevention have shown that a molecular change in the 1918 pandemic influenza virus stops its transmission in ferrets that were in close proximity, shedding light on the properties that allowed the 1918 pandemic virus to spread so quickly and potentially providing important clues that could help scientists assess emerging influenza viruses, such as H5N1.
