NCAR analysis shows widespread pollution from 2004 wildfires

...ortant to see how the influence of these fires can reach large parts of the atmosphere, perhaps even over the entire Northern Hemisphere," says NCAR scientist Gabriele Pfister, the study's lead author. "This has significant implications as societies take steps to improve air quality." Carbon monoxide, a t...

Asian immigrants in NYC not receiving HIV education at religious institutions

...se institutions are missing a vital opportunity to reach masses of immigrants for whom a temple or mosque is the only connection with a formal support system and therefore a potentially critical source of life-saving health information, said lead author John J. Chin, Ph.D., Senior Research Associate in the...

New study to explore cellular circuitry

...hysics at the medical center. "That puts us within reach of a completed diagram and the ability to re-wire cells in the treatment of disease." Medical Center Tapped for its "Library" At the outset of the NSF project, researchers know the exact composition of the genes of S. cerevisiae. Gene sequences...

Researchers find Amchitka seafood safe for now

...made clear and unambiguous efforts consistently to reach out to affected Aleut communities as they defined their scientific plan and then included Aleuts on the expedition itself to aid in collection of samples. What is CRESP? It is interdisciplinary multi-university organization through which senior sc...

Scientists crack 40-year-old DNA puzzle and point to 'hot soup' at the origin of life

...ke on new amino acids. Whether we could eventually reach a full complement of 64 amino acids I don't know, a compromise between amino acid vocabulary and its error minimising efficiency may have fixed the genetic code in its current format." ...

Gene therapy reverses genetic mutation responsible for heart failure in muscular dystrophy

... a large amount of the virus so there is enough to reach every muscle cell. Because 30 percent to 40 percent of the population has antibodies to human AAVs, there is always the possibility that the effectiveness of this form of gene therapy may be blunted by a host immune response. However, Dr. Xiao is opt...

NC State researchers redesign life for Mars and beyond

...lls in underwater sea volcanoes where temperatures reach more than 100 degrees Celsius, or that of boiling water. Occasionally, the organism is spewed out into near freezing deep-sea water. The NC State research, funded for two years and $400,000 by the NASA Institute forAdvanced Concepts, entails extract...

Hand sanitizer gel works

...smit respiratory illnesses, but this effect didn't reach statistical significance. "We think that's probably because people were more diligent about using the sanitizer after a GI-related incident, such as using the bathroom or vomiting, than after a respiratory incident, such as nose-wiping or sneezing,"...

Biotechnology's newest chemical tool

... required an auxiliary "spring" to ensure it would reach the target. So, he said, "chemical thinking" helped resolve the problematic enzymatic reaction. "By demonstrating the transfer of carbon chains as long as 4 to 5 units, we provide proof of principle that further extensions should also be tolerated,...

Biotechnology's newest chemical tool

...system, allowing sensory feedback from the hand to reach the brain, and instructions to come from the brain to control the hand, at least in part. Coordinated by Professor Paolo Dario with Professor Maria Chiara Carrozza leading the development of the hand, the project united researchers from Germany, Spa...

Prenatal exposure to marine toxin causes lasting damage

...rabs. Fisheries are closed when domoic acid levels reach 20 parts per million (ppm) in the animals' tissues, the level at which the FDA deems the toxin unsafe for human consumption. Earlier studies in animals have focused on lethal and highly toxic doses of domoic acid. Such exposures cause extensive dam...

Chernobyl: The true scale of the accident

Give thanks for the cranberry, say dental researchers

...ranberry juice is under study, so diners shouldn't reach for the cranberry sauce just to stop the tooth decay brought on by carbohydrate-laden foods like mashed potatoes, rolls, and pumpkin pie. He recommends traditional measures to avoid cavities: Brush your teeth after dinner, don't snack often, stay awa...

New genetic test can detect clam disease

...ratory, to find out what triggers the organisms to reach concentrations that become deadly, and whether that threshold varies among clam strains. Smolowitz uses traditional microscopic examination of tissues to determine if clams are sick. Gast's genetic test can now also be used to ensure clams without...

Seafloor creatures destroyed by ice action during ice ages

...for ten years. In the Antarctic these starfish can reach 100-years-old but reproduce only once every ten years. This means that full community recuperation takes up to hundreds of years.'

Nanoparticles, nanoshells, nanotubes: How tiny specks may provide powerful tools against cancer

... and Diagnosis (Abstract 3891) Getting drugs to reach cancer cells once they have spread from the original site of the tumor in the body has continually frustrated physicians and researchers. But now, scientists are combining a novel kind of "nanocomplex" consisting of a microscopic, lipid-based liposom...

Past experience of pheromones induces dominant courtship behavior in fruit flies

The work is reported by Jean-Francois Ferveur and colleagues at the Universite de Bourgogne, France, and the University of Manchester, United Kingdom. When an adult male fruit fly encounters a young male fly, he will actively court the yo...

Envisat radar surveillance protects endangered prehistoric fish

...othfish can live for 40 years but take a decade to reach adulthood: their slow-maturing character makes them especially vulnerable to overfishing. As toothfish numbers have crashed in heavily fished waters off Chile and Argentina, fishermen are increasingly drawn to Southern Ocean fisheries. However st...
