More recycling on the farm could reduce environmental problems
...rtilizer and would exploit robotic systems. The approach
would entail more use of human labor, which is costly, and may reduce output per unit area farmed. Pearson summarizes studies of organic farming suggesting, however, that price premiums could overcome this disadvantage, and points out that social ben...
Technique monitors thousands of molecules simultaneously
... Scientists at CombiMatrix initially pioneered an approach
for covering the chip with a polymer, attaching a ...thesis of DNA and peptide polymers. But could this approach
be used to make the more difficult to synthesize shaped molecules needed for mapping a receptor? Thi...
Novel system developed to turn data into real-time, interactive 3-D images
...a variety of imaging techniques," Blank says. "Our approach
allows the physician to rapidly and efficiently study hundreds of images at once by turning the data into a three-dimensional (3-D) object that appears to float in midair." The technology will allow for manipulation of the volume-rendered object ...
Anthrax paralyzes immune cells with lethal toxin, UF research shows
...in expression. Southwick's team used an unusual approach
to tease out the anthrax toxin's effects on cell migration: They allowed the immune cells to be hijacked by another bacterium, Listeria monocytogenes. Listeria is often used as a tool to study actin because it commandeers human cells and induces them...

to analyzing how proteins regulate cell movement." The research team’s profile of chemotactic cells is the first and most comprehensive catalog of proteins that exists to date, according to Yingchun Wang, a post-graduate researcher in the Klemke l...
Students invent protective pouch to enhance cell therapy
...end out needed insulin. The inventors say the same approach
could be used in cell therapy for other ailments, including liver disease. "I think it's a brilliant idea," said one of the project's sponsors, Jeff W. M. Bulte, director of the Cellular Imaging Section in the Johns Hopkins Institute for Cell Engi...

includes two components: the use of mechanical devices to spread and flatten the cells, and the appl...
Fat screen delivers plant-derived chemical with antidiabetic effects
... published by Cell Press. The work suggests a new approach
for treating insulin resistance that might complement the use of preexisting drugs and, more generally, provides validation for fat cell screens as a promising strategy for identifying new metabolic drugs, according to the researchers. While harmi...
New bacteria test could improve quality of fruit and vegetable juice
...and Natural Resources, has successfully used a new approach
combining DNA sequencing technique with mid-infrared spectroscopy to rapidly and accurately identify Alicyclobacillus, a common bacterium found in apple, carrot, tomato, orange and pear juices, tropical fruit juices and juice blends. The bacterium wo...
Scientists identify prion's infectious secret
...ese findings provide researchers with a new way to approach
old questions, such as why some prion diseases can jump from one species to another but others can’t. Tessier and Lindquist say it is likely that natural prions contain more than one recognition element, and recognition elements can slide into a neig...

LIAI scientists make important finding on cytomegalovirus transmission
... more effectively battle the virus. "We used this approach
to tip the balance in favor of the T cells that would reduce the virus," he said. The scientists got a stronger result by blocking the IL-10 receptor. "It significantly reduced the virus load in all the animals and in 50 percent of them it comple...

to increasing adoption of household bans," says Dr. Shelley. The study suggests that while household smoking bans cannot be legislated, governmental agencies can increase their efforts in developing and testing effective interventions to promote ...
Study warns deep-sea mining may pose serious threat to fragile marine ecosystems
..." The mining operations will use a strip-mining approach
to remove deposits within the top 20 metres of the seafloor, using remotely operated underwater mine cutters and a hydraulic pump system to transfer roughly two million tons of ore per year to the surface. These strips would be located approximately ...
