  • Cellular `computers` gain a hard drive

    A new DNA-based recorder allows bioengineers to create cell cultures that detect information in their environment and store it for later use. Such 'designer' cells might in the future be used to monitor water quality in a village, or measure the amount of sugar a person eats. The technique is described this week in ...

  • Team probes mysteries of oceanic bacteria

    Microbes living in the oceans play a critical role in regulating Earth's environment, but very little is known about their activities and how they work together to help control natural cycles of water, carbon and energy. A team of MIT researchers led by Professors Edward DeLong and Penny Chisholm is trying to change that. Borrowing gene sequencing tools developed for sequencing the human ...

  • Oil spills could be cleaned up by bacteria from underground petroleum reserves

    Bacteria taken from underground petroleum reserves could be used to effectively break down crude oil from spills at sea, new research has found. The study measured the breakdown of crude oil components in simulated seawater by four bacterial strains that had been isolated from petroleum reservoirs, as well as by four genetically modified stains. The findings raise the possibility of tailor-making ...

  • Shifts in soil bacteria linked to wetland restoration success

    A new study led by Duke University researchers finds that restoring degraded wetlands -- especially those that had been converted into farm fields -- actually decreases their soil bacterial diversity. But that’s a good thing, say the study’s authors, because it marks a return to the wetland soils’ natural conditions.“It sounds counter-intuitive, but our study shows that in restored wetlands, ...

  • Mercury-resistant bacteria useful for studying toxic metal cycling

    Mercury-resistant bacteria could help scientists to understand more about mercury cycling in the environment. In a new study, researchers identified one particular strain of soil bacterium that could serve as a model for the conversion of the toxic metal into less toxic forms. They also discovered a new gene involved in the conversion process. Bacteria play an important role in the cycling of ...

  • Genes and GPS used to map spread of typhoid

    A combination of geographic and genetic data is showing how typhoid fever spreads, and could be used for mapping other disease patterns, a study has reported. Researchers used DNA sequencing, global positioning system (GPS) and Google Earth technologies to track typhoid transmission in Kathmandu, the rapidly growing capital city of Nepal, where thousands fall ill with typhoid fever each year. ...

  • Environmental monitoring in Texas moves into watershed protection plan development

    Results from a three-year monitoring study indicate that Buck Creek in the southeastern part of the Texas Panhandle is not excessively contaminated, and experts are advocating it should be taken off Texas’ list of impaired water bodies. “Overall the creek is in good shape,” said Lucas Gregory, project manager with the Texas Water Resources Institute in College Station. Gregory and other officials ...

  • EMSL analytical chosen to perform advanced PCR detection for EPA

    Bacterial contamination levels of recreational waters to be tested by EMSL’s state-of-the-art PCR laboratory. EMSL Analytical has been awarded the contract for rapid PCR detection of bacteria contamination in recreational water for the EPA. The EPA contract, EP-D-04-064, is being managed by Westat in Maryland. EMSL has a long history of providing these types of analytical testing services to ...


  • Genome of nitrogen-fixing, soil-living bacterium sequenced

    A collaboration of researchers, which includes scientists at the Virginia Bioinformatics Institute (VBI) and Virginia Tech, have completed the genome sequence of Azotobacter vinelandii, uncovering important genetic information that will contribute to a more complete understanding of the biology of this versatile, soil-living bacterium. The work will help advance research on A. vinelandii's role ...

  • Rapid Detection of Pathogens and Mold in

    Society has become acutely aware that infection-causing pathogens can be found in food, drinking water and the surrounding environment. Properly testing for pathogens is a very effective approach for preventing these infections. In spring and summer, E.coli O157:H7, Salmonella, Clostridium botulinum and Shigella are the common food borne bacterial pathogens. Helicobacter pylori and Enterovirus ...
