Powerful genome ID method extended to humans

...e late 1990s by David Schwartz, now a professor of chemistry and genetics at the University of Wisconsin-Madison. Schwartz and a collaborator at Wisconsin, Shiguo Zhou, co-authored the PNAS paper. The power of optical mapping lies in its ability to reveal the size and large-scale structure of a genome. The ...

From a lowly yeast, researchers divine a clue to human disease

...r of the new study and a professor of biomolecular chemistry in the UW School of Medicine and Public Health. A host of proteins are responsible for controlling which genetic messages are read and how much of the information is used. Working with yeast, Brow and his colleagues show that a protein called Sen1 ...

Scientists win grants to develop $1,000 genome sequencing technology

... and nano-fabrication technologies with innovative chemistry technologies to simultaneously sequence more than 1 billion individual pieces of DNA attached to the surface of single slides. The latest genome-sequencing grant was announced simultaneously with the announcement of the Archon X PRIZE for Genomics...

From hot springs to rice farms, scientists reveal new insights into the secret lives of archaea

...itution will discuss the effect of temperature and chemistry on archaeal communities inhabiting marine hydrothermal vents on the island of Vulcano, Italy. Several species of thermophilic archaea live in these shallow waters, where temperatures sometimes approach the boiling point. Rogers found that there were ...

Why do insects like to eat some plants more than others?

... variation in the nutritional quality or defective chemistry of plant tissues. However, the researchers found that cactus-feeding insects chose host plants based on how the plants allocated resources between growth and reproduction. "The crux of our findings is actually quite intuitive", says Miller. "These...

Silver bullet: UGA researchers use laser, nanotechnology to rapidly detect viruses

... But UGA physics professor Yiping Zhao and UGA chemistry professor Richard Dluhy experimented with several different metals and methods and found a way to significantly amplify the signal. Using a method they've patented, they place rows of silver nanorods 10,000 times finer than the width of a human hair ...

Nanotech tools yield DNA transcription breakthrough

...es Medical Institute investigator and professor of chemistry and chemical biology at Rutgers, The State University of New Jersey. "These methods enabled us to analyze and manipulate individual molecules of the machine, one-by-one, as they carried out reactions." The discoveries significantly advance our und...

MIT designs portable 'lab on a chip'

.... Labs on a chip can also be used in traditional chemistry or biology labs to speed up processes such as DNA testing or screening for the presence of certain antigens. Only tiny amounts of reactants would be needed, and experiments could be done more rapidly and efficiently. "Instead of a thousand people ...

Psst! Coffee drinkers: Fruit flies have something to tell you about caffeine

...ys Craig Montell, Ph.D., a professor of biological chemistry in the Institute of Basic Biomedical Sciences at Hopkins. "The bottom line is that our mutant flies willingly drink caffeine-laced liquids and foods because they can't taste its bitterness -- their taste receptor cells don't detect it." The Hopkins ...

Brains can recover from alcoholic damage but patients should stop drinking as soon as possible

...ngible, and rapid benefits of sobriety: cognition, chemistry and brain volume," wrote the associate professor of diagnostic radiology and psychiatry at Yale University. Prof Mason believed this was a particularly valuable contribution of the study because "patients often become discouraged from the physical a...
