Tiny particles could solve billion-dollar problem

...th TCE molecules and improve efficiency by several orders of magnitude over bulk palladium catalysts." TCE, which is commonly used as a solvent to degrease metals and electronic parts, is one of the most common and poisonous organic pollutants in U.S. groundwater. It is found at 60 percent of the contamina...

Researchers reveal the infectious impact of salmon farms on wild salmon

... lice production from the farm we studied was four orders of magnitude - 30,000 times - higher than natural. These lice then spread out around the farm. Infection of wild juvenile salmon was 73 times higher than ambient levels near the farm and exceeded ambient levels for 30 kilometers of the wild migration...

Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra

...y of breeding seabirds on fox-free islands was two orders of magnitude higher than on fox-infested islands. The resulting difference in nutrient inputs was reflected in soil phosphorus levels that were more than three times higher on fox-free islands. The vegetation on the islands also showed significant di...

Stanford gut check shows diversity of intestinal ecosystem

...with this large sequencing project, which produced orders of magnitude more sequence data than had been generated in the past, we are not completely there yet. This is just the tip of the iceberg." Eckburg works with David Relman, MD, associate professor of medicine (infectious diseases and geographic medi...

Microarrays as phenotype

... Using microarray data alone, they determined the orders in which genes function in a particular pathway in that organism. The protein kinase A (PKA) signaling pathway occurs when the organism encounters starvation. The pathway enables the single cells to combine into a multi-cell organism. "We pretended ...

High fidelity keeps human DNA assembly line humming

...al that holds the blueprint for life. DNA dictates orders to RNA to make proteins, which give a cell its identity. Mistakes in RNA synthesis can lead to cancer or can support the life cycle of an invading virus. Researchers consider control of RNA synthesis to be a huge issue in human health. It is also the...

Using computers and DNA to count bacteria

...pristine soil, exceeding previous estimates by two orders of magnitude. When we examined the populations levels in metal-contaminated soil, we found the bacterial genetic diversity was reduced more than 99.9 percent," lead author Gans added. The Los Alamos team used a technique known as DNA re-association,...

New discovery: If it weren't for this enzyme, decomposing pesticide would take millennia

...e half-life of the pesticide is longer, by several orders of magnitude, than the half-lives of other known environmental pollutants in water," Wolfenden said. "The half lives of atrazine, aziridine, paraoxon and 1, 2-dichloroethane, for example, are five months, 52 hours, 13 months and 72 years, respectivel...

Polymer gel can block toxic leakage problem in gene therapy

...s mixture "could reduce virus dissemination by two orders of magnitude (100 times) and significantly increase transgene expression in solid tumors," their study reported. In comparative tests on breast tumors implanted in live mice, the authors noted that two mice in the group injected with adenoviruses wi...

Is it Possible to Change Prescribing Habits?

MIT: Oceans are a major gene swap-meet for plankton

...Chisholm said. "We found first that two clades are orders of magnitude more abundant than all of the rest, and that temperature appeared to be very important in determining their distributions." Subsequent laboratory experiments with the cultured strains confirmed this idea. Further analysis showed that mo...

Scientists design potent anthrax toxin inhibitor

...inhibitor binds the toxin at multiple sites and is orders of magnitude more potent than an inhibitor that binds at a single site. The multiple peptides on the functionalized liposome are arranged with the same average spacing as the binding sites of the PA molecule, which permits a firmer bond between the t...

Anthrax inhibitor counteracts toxin, may lead to new therapeutics

...owing it to bind at multiple sites and become four orders of magnitude more potent than an inhibitor that binds to a single site. "Think about how two Lego blocks snap together. A brick with four studs can interlock with a brick with four holes. These bricks will grip together better than if they had only...

New test to detect rare proteins in blood

...tion Catalyzed by T7-polymerase Technique, is five orders of magnitude (100,000 times) greater than that of ELISA, the Penn researchers found. Senior author Mark I.

Data published in PNAS show antibodies can be made 10 times more toxic to cancer cells

...ell-mediated Cytotoxicity (ADCC), by more than two orders of magnitude. Studies conducted in in vivo models demonstrated that these antibodies were greater than ten times more toxic to target cells. The enhanced antibodies also were able to kill tumor cells that are typically "invisible" to other antibodie...

How plants avoid feeling the burn

...d form. However, the electrical conduction was two orders of magnitude higher when compared to what is needed for the photoprotective effect to work. The group also measured how fast the electrons traveled across the carotenoid bridge between the electrodes. By measuring carotenoids of different chemical ...

Scientists reverse evolution
