Computer model maps efficient inoculation of hospital staff in pandemic outbreak
...s regarding patient-care, the paper said. "While individual
hospitals have initiated varying degrees of preparedness planning, there are currently no guidelines or best-practice examples for this aspect of hospital protection in recently released national health emergency plans. We hope that this study will r...
Study of protein folds offers insight into metabolic evolution
...aic shows that modern metabolic networks and even individual
enzymes are composed of both very ancient and much more recent protein architectures. "This mosaic is telling you that the new enzymes and old enzymes are together performing side by side," Caetano-Anolls said. "In some cases in the same protein y...

organism's genetic machinery --to perform biological functions." TEs may be developed as genetic tools to study the interaction between mosquitoes and pathogens, and thus may lead to controls of transmission of disease, Tu said. Control might take...
Executable biology -- Computer science sheds light on animal development
...ays takes place in order to determine the fates of individual
cells. The novel in silico model is described in a paper appearing May 18, 2007 in the open-access journal PLoS Computational Biology. During C. elegans development, uncommitted precursor cells differentiate into two distinct cell types in respons...
Newly identified mechanism for silencing genes points to possible anti-cancer strategies
Genes provide the instructions used by the individual
cells to produce the many different proteins that make up the body. Scientists are only beginning to appreciate, however, the extraordinary degree of control exercised over every step of the production process. Only about 10 percent of human genes...
Decoding protein structures helps illuminate cause of diabetes
...up now plans to capture series of snapshots during individual
folding reactions to identify multiple phases as the proteins convert from an unordered mishmash into flat sheets, then coil into fibers. "No matter how fast they're moving, we can take pictures of them," says Zanni. Without their automated metho...
Soy estrogens and breast cancer: Researcher offers overview

chemical parts. "That raw food can be consumed for less than a dollar a serving and is likely better for you than that thing you pick up at the health food store for $30 a pound," he said. ...
