New possibilities for flu antiviral and vaccine research emerge from 'Spanish flu' virus

...an flu viruses. Many experts say that it is only a matter of time before an avian flu outbreak occurs in humans and develops into a global pandemic, potentially costing millions of lives. Therapies against a new flu strain would need to disarm the parts of the virus that do the most damage to the body. In ...

Gene therapy for muscular dystrophy fixes frail muscle cells in animal model, Stanford study finds

...lls of the body. For his part, Rando said that no matter how well gene therapy works in an isolated muscle, researchers still must figure out how to get that gene to muscles throughout the body. Despite the remaining hurdles, both Rando and Calos said that their study is a step towards eventually treating ...

Scientists discover the molecular switch for nerve cells' insulating jelly rolls

...ation in nature. Myelin forms the so-called white matter in the nervous system and constitutes 50 percent of the weight of the brain. It is also an important component of the spinal cord, and of nerves in other parts of the body. It has been known for almost 170 years that there are two kinds of axons --on...

Building a better mouse model of lung cancer: FHIT counts

Approximately 120 million people in the United States wear eyeglasses or contact lenses to correct nearsightedness, farsightedness, or astigmatism. These vision disorders are often the result of incorrect curv...

Emerging staph strains found to be increasingly deadly and deceptive

...ue, can easily be treated and usually resolve in a matter of days. But S. aureus disease also can be much more severe and difficult to treat, affecting vital organs and leading to toxins poisoning the blood and infection overwhelming the heart. One of the most severe types of disease is necrotizing pneumoni...

Color perception is not in the eye of the beholder: It's in the brain

...t in the brain that balances the colors for you no matter what the hardware is." In a related experiment, Williams and a postdoctoral fellow Yasuki Yamauchi, working with other collaborators from the Medical College of Wisconsin, gave several people colored contacts to wear for four hours a day. While wear...

Researchers find ways to turn manure into power

...lt, the low-ash manure had about twice the organic matter and heating value, he said. "The low-ash feedlot biomass would be much better fuel than high-ash feedlot biomass," Sweeten said. "The problem is, there is not that much of it in the commercial feedlots." Large bulk samples from the compost pile tha...

DDT-resistant insects have additional genetic advantage that helps resistance spread

...s begun now, most mosquitoes become resistant in a matter of months rather than years. Worryingly, some resistant strains also show 'cross-resistance' to a number of different compounds, so spraying with one insecticide can unexpectedly increase resistance to newer compounds subsequently introduced to try ...

North & South American researchers find architectural abnormalities in T. cruzi ribosome

In the brain, there is a dynamic change that allows certain pathways to preferentially facilitate the demands of a given cognitive task. The brain highway in effect "adds lanes" to a...

NASA satellite data provides rapid analysis of Amazon deforestation
