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.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
