Researchers at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility have produced first light from their 10 kilowatt Free-Electron Laser (FEL). This device has been upgraded from the "one kilowatt Infrared Demonstration" FEL, which broke power records by delivering 2,100 watts of infrared light during 2001. Only one and one-half years after the one kilowatt FEL was dismantled, the newly improved FEL, designed to produce 10 kilowatts of infrared and one kilowatt of ultraviolet light, is undergoing commissioning toward the goal of producing 10 kilowatts by summer’s end.
According to Rear Admiral Jay Cohen, Chief of Naval Research, "This project builds on the successful seven-year partnership forged between the Office of Science’s Jefferson Lab and the Office of Naval Research. The original kilowatt FEL exceeded the Navy’s goals and expectations and we expect no less from the upgraded FEL."
The Free-Electron Laser upgrade project is funded by the Department of Defense’s Office of Naval Research (ONR), Air Force Research Laboratory and the Joint Technology Office. Jefferson Lab is managed for the Department of Energy’s Office of Science by a consortium of universities in the southeast called the Southeastern Universities Research Association.

In meningococci, the RNA-binding protein ProQ plays a major role. Together with RNA molecules, it regulates processes that are important for pathogenic properties of the bacteria.
Meningococci are bacteria that can cause life-threatening meningitis and sepsis. These pathogens use a small protein with a large impact: The RNA-binding...
An analysis of more than 200,000 spiral galaxies has revealed unexpected links between spin directions of galaxies, and the structure formed by these links...
Two prominent X-ray emission lines of highly charged iron have puzzled astrophysicists for decades: their measured and calculated brightness ratios always disagree. This hinders good determinations of plasma temperatures and densities. New, careful high-precision measurements, together with top-level calculations now exclude all hitherto proposed explanations for this discrepancy, and thus deepen the problem.
Hot astrophysical plasmas fill the intergalactic space, and brightly shine in stellar coronae, active galactic nuclei, and supernova remnants. They contain...
In living cells, enzymes drive biochemical metabolic processes enabling reactions to take place efficiently. It is this very ability which allows them to be used as catalysts in biotechnology, for example to create chemical products such as pharmaceutics. Researchers now identified an enzyme that, when illuminated with blue light, becomes catalytically active and initiates a reaction that was previously unknown in enzymatics. The study was published in "Nature Communications".
Enzymes: they are the central drivers for biochemical metabolic processes in every living cell, enabling reactions to take place efficiently. It is this very...
Early detection of tumors is extremely important in treating cancer. A new technique developed by researchers at the University of California, Davis offers a significant advance in using magnetic resonance imaging to pick out even very small tumors from normal tissue. The work is published May 25 in the journal Nature Nanotechnology.
