Microbes that live in rice paddies, northern peat bogs and other previously unexpected environments are among the bacteria that can generate highly toxic methylmercury, researchers at Oak Ridge National Laboratory and the Smithsonian Environmental Research Center have learned.
More forms of mercury can be converted to deadly methylmercury than previously thought, according to a study published Sunday in Nature Geoscience.
Scientists of the Next-Generation Ecosystem Experiments are blogging from the Arctic this summer. Follow their adventures at . Participants share troubles and triumphs from the field in entries with headings like "Flying Wild Alaska" and "Hitting the Tundra." "The b...
Whole-ecosystem warming technologies for the 10- year Spruce and Peatland Responses Under Climatic and Environmental Change project have been finalized using prototypes designed at Oak Ridge National Laboratory. Construction has begun in Minnesota to deploy the technologies, which will warm the...
Bio-SANS, the Biological Small-Angle Neutron Scattering Instrument at HFIR recently had a detector upgrade that will provide significantly improved performance that is more in line with the instrumentās capability.
We now know that many serious diseases have genetic links that a geneticist can find by reading an individualās genomeāthe DNA double helix where our organismās hereditary information is encoded. Researchers know too that a particular protein protects our DNA, which is vulnerable to entanglement when its information is read and to attack from enzymes that damage the strands, making the code indecipherable.
Researchers at the at the used small-angle neutron scattering (SANS) to get a first insight into the conformation of single polyelectrolyte chains in large pieces of the synthetic complex. The research pursues applications for replacement of intervertebral discs in the spine and of knee cartilage.
Imagine an instrument that collects thousands of diffraction data points in days instead of months with the help of a cylindrical image plate detector and an intense polychromatic neutron beam. IMAGINE is the newest single crystal diffractometer being installed at the High Flux Isotope Reactor, and ...
Researchers have long thought that formation of insoluble fibrous āstringsā of self-assembling proteins might be involved in the progression of a number of diseases, including neurodegenerative disorders such as Alzheimerās and Parkinsonās. However, recent evidence suggests that aggregates that develop at an earlier stage than fibril formation, and accumulate in human organs, may be the primary toxic agents.
