NIEHS launches website with information for assessing environmental hazards from Hurricane Katrina

...cultural operations, as well as maps and satellite images of schools, neighborhoods, and medical facilities, that will help assess the short and long effects of Katrina on the Gulf region. "With a disaster of this magnitude, people need many things, including easy access to science based information so th...

FDA: 'Highly Unlikely' Green Tea Lowers Cancer Risk

...lders and eyes fixed on lenses for sharp magnified images of the surgical site. Focus is adjusted via foot pedals. While laparoscopy allows manipulation of instruments up, down and side-to-side, surgery with the da Vinci allows more natural wrist movement. The robot's arms have wrists with eight degrees o...

Cells direct membrane traffic by channel width

...ycerol channel. Side-by-side in computer-generated images the channels appear virtually identical. The Beckman teamed pushed glycerol through the channels, calculated the energetics and looked for barriers. "Nature is using a very, very simple idea here," Tajkhorshid said. "Just by making a channel narrowe...

Learning how SARS spikes its quarry

...chers have determined the first detailed molecular images of a piece of the spike-shaped protein that the SARS virus uses to grab host cells and initiate the first stages of infection. The structure, which shows how the spike protein grasps its receptor, may help scientists learn new details about how the v...

Retina adapts to seek the unexpected, ignore the commonplace

...als in retinal ganglion cells, which convey visual images from the eye to the brain. These cells generally record local spatial differences and changes over time rather than faithful renditions of momentary scenes. Scientists had interpreted this as a form of predictive coding, a strategy shaped by the forc...

Researchers find how some antibiotics kill bacteria

...icient enough to see that." The higher-resolution images also showed that rifapentin and rifabutin each bind just a little differently to E. coli, but still bring about the same results. The answer to creating a new breed of bacteria-resistant antibiotics may lie in these variations in binding. "From the...

From a Few Wild Ancestors, a Citrus Cornucopia

For most of us, the word “citrus?conjures up images of oranges, grapefruits, lemons, limes -- and possibly citrons or blood oranges, if you’re a true connoisseur of fruit. But for ARS horticulturalist Robert R. Krueger, the genus Citrus includes at least 16 species, with hundreds of distant relatives...

Unweaving amyloid fibers to solve prion puzzles

...ds. And scientists depend on these high resolution images of molecules in order to study their function. Now, researchers have found a way to work around these limitations, illuminating the configuration of these sometimes pernicious molecules. And even though this work was done in yeast, the results provi...

UIC developing drug for SARS

He will create computer images of each enzyme coupled with compounds anticipated to obstruct the pockets, revealing whether and how tightly the molecules fit in the space. If the fit is poor, he can explore a library of alternative molecules that might meet the chemical and config...

MERIS monitoring tracks planetary photosynthesis levels

...oducts are basically mosaics created from multiple images acquired by MERIS over the course of the month. Handling and processing this much data is extremely demanding in processing power, but ESRIN's Grid-On-Demand service makes it feasible. Grid computing takes its name and organising principle from th...

Envisat and ERS-2 reveal hidden side of Hurricane Rita
