Tiny particles could solve billion-dollar problem

...nic parts, is one of the most common and poisonous organic pollutants in U.S. groundwater. It is found at 60 percent of the contaminated waste sites on the Superfund National Priorities List, and it is considered one of the most hazardous chemicals at these sites because of its prevalence and its toxicity. H...

The secret lives of whales

...adly contaminated oceanic fish are with persistent organic pollutants (POP’s),?says Payne, “What we are working on may be the worst public health crisis that humanity has ever faced. That’s because 70% of all humanity (4.2 billion people) depends on seafood as its primary source of animal protein, and if the...

Dinosaur DNA? New Patent Covers Degraded DNA recovery

... when DNA was recovered from 12 samples of ancient organic remains, ranging in age from 4 to 13,000 years. The remains included several Egyptian mummies and two extinct species -- the marsupial wolf and ground sloth. Plant DNA up to 400,000 years old, and DNA from the extinct mammoth and steppe bison have be...

Sea skate experiment sheds light on human cell transport

...to release excess water along with salts and other organic material. The researchers made their discovery by using a plant-based substance to block an enzyme that causes phosphorylation. The result: The gates wouldn't open. These findings are published in the current issue of the American Journal of Physiol...

Solution to Pollution: New Bacteria Eats Toxic Waste

...living organisms to degrade or transform hazardous organic contaminants using natural biology. It offers an attractive solution to pollution cleanup because it can occur on-site and at relatively little cost compared to other alternatives, he continued. The team received a $1.5 million dollar contract from t...

Nano-Probes Allow an Inside Look at Cell Nuclei

...olecules. In contrast, conventional labels such as organic fluorescent dyes and green fluorescent proteins only fluoresce for a few minutes at a high resolution. These labels are also either toxic to cells or difficult to construct and manipulate. In the future, they hope to tailor quantum dots to track spe...

NC State scientist finds soft tissue in T. rex bones

UCSD discovery may help extend life of natural pesticide

... pesticide produced by bacteria and widely used by organic farmers and in genetically engineered crops to ward off insect pests. Their findings should facilitate the design and use of Bt toxins to prevent insects, which the researchers believe also possess the molecule, from developing resistance to Bt, ext...

South America's vast pantanal wetland may become next everglades, UNU experts warn

...f all carbon held in terrestrial sinks, most of it organic matter in soil which can be released when the soil is disturbed, for example through wetlands drainage and destruction. Already, changes in land use and land cover account for about 1.6 gigatonnes (17%) of annual human-caused carbon emissions, the a...

Microbial fuel cell: High yield hydrogen source and wastewater cleaner

...lds of hydrogen from any biodegradable, dissolved, organic matter -- human, agricultural or industrial wastewater, for example -- and simultaneously clean the wastewater. "While there is likely insufficient waste biomass to sustain a global hydrogen economy, this form of renewable energy production may help...

Newly discovered pathway might help in design of cancer drugs

... itself." In the lab, Greenberg and his team used organic chemistry to create a synthetic, double-stranded DNA with special chemical characteristics and exposed it to long wavelength light that selectively switches on the DNA damage process. He said that the synthetic DNA is very similar to that which is p...

To control germs, scientists deploy tiny agents provocateurs

...e researchers have so far unveiled three promising organic compounds that seemingly quell bacterial signaling. ...

NASA study finds snow melt causes large ocean plant blooms

...e deeper waters are not well ventilated. Also when organic matter produced by phytoplankton breaks down and decomposes, more oxygen gets consumed in the process. An increase in phytoplankton could therefore cause oxygen deficiencies in the Arabian Sea to spread, leading to fish mortality. Oxygen-depleted wa...

Growth in biomass could put US on road to energy independence

...rategy in which 1 billion dry tons of biomass ?any organic matter that is available on a renewable or recurring basis ?would displace 30 percent of the nation's petroleum consumption for transportation. Supplying more than 3 percent of the nation's energy, biomass already has surpassed hydropower as the larg...

Could microbes solve Russia's chemical weapons conundrum?

...ducts of their detoxification. "Bioutilization of organic compounds of reaction masses is a biotechnological method that pro-vides maximum environmental safety, since the pollutants are naturally degraded to innocuous products such as carbon dioxide and water, as well as microbial biomass," said Dr. Ermakov...

Study uncovers bacteria's worst enemy

...ater and combinations of actinides, radionuclides, organic chemicals and metal regularly exist at many nuclear sites. Based on the results of this study, if bioremediation is to be effective at these types of sites, the operative microorganisms must be able to grow, function and do better than other bacteria...

Hydrogen and methane provide raw energy for life at 'Lost City'

...microorganisms ?comparable to what's found in rich organic sediments. However the diversity of species is low with, for example, just a handful of methane-producing and methane-consuming Archaea. In surprising contrast, researchers discovered Lost City has a diversity of "larger" organisms that's as high, o...
