New Biochemical Technology Ready To Retrieve, Purify Heaviest Crude Oil

... extract and use it. Conventional technology for extracting petroleum typically leaves behind morethan 60 percent of the original oil. Also, today's technology is notcost-effective for the lowest-grade crudes. So, Brookhaven scientists haveworked for several years to develop bacterial biocatalysts that can w...

The Sagan criteria for life revisited

...al maturity. They can be detected remotely without extracting organic matter to reveal oil shales and source rock that came from the decay of green plants. Does the presence of porphyrins mean that there is or has been life on the Moon? Not at all. The 1969 discovery of lunar porphyrins probably says less...

With support for the EPA, biologists go out on a genetic limb to help stem migratory songbird declines

...edinggrounds throughout the U.S. and Canada. After extracting DNA from the blood or feather, team members sequence the DNA,then identify a molecular marker that shows a high frequency of haplotypes, or"tags," that are unique to specific geographic areas and subpopulations. Forexample, the genetic tag of a subpo...

A little help from below: naturally occurring microbes ready to lend a hand trapping radioactivity underground

...um-90 underground should be cheaper and safer than extracting it, said INEEL geochemist Bob Smith who leads the project. "If you were to do some sort of treatment where you brought it to the surface, you'd have to expose workers, you'd have to ship it, you'd have to pack it," he said. The researchers hope to...

Genome scientists muster computer software tools for handling the flood of raw data from the Human Genome Project and related efforts

... to come up with sophisticated computer models for extracting useful information from them," said David Haussler, professor of computer science at the University of California, Santa Cruz. Haussler discussed the use of computational techniques to analyze genetic data in a talk Saturday (February 19) at the an...

Drugs on tap

... produce everything from vaccines to plastics. But extracting proteins from plant tissue is often complicated and expensive. Instead, Ilya Raskin and his colleagues at Rutgers University in New Jersey wondered if plants could excrete proteins in the "dew drops" found on leaves. During the night, when leaves...

Scientists discover how nerve cells move from target to target as they wire up the developing embryo

...ifts the information in this "mixed signal," first extracting the attractive information, then dramatically switching its behavior to ignore attraction and only perceive the repulsive information. The new research also establishes that the mechanism actually predetermines the outcome any time an axon encounters...

X-ray crystallography at Advanced Photon Source

... protein molecule from a crystal. It does this by extracting so-called phase data from X-ray patterns measured at several different wavelengths and by looking at the differences in intensity of those measurements. In addition to the NIH funding, the NE-CAT project also will receive $6.6 million from member ins...

Researchers announce anthrax breakthrough

...TR region and the receptor-binding area of PA. By extracting the special region from the rest of ATR and releasing it into the extracellular area, the scientists found they could entice PA away from the cell surface. This action prevented PA from entering the cell and from delivering a specifically engineered ...

Answers to Florida bay restoration are clear as mud!
