Two years ago, researchers at the Advanced Light Source (ALS), a "soft" or low-energy x-ray synchrotron at Lawrence Berkeley National Laboratory in California, were stunned by a harsh review from a scientific advisory panel assembled by the U.S. Department of Energy, which oversees the facility. But last month, another panel concluded that the ALS is steering a much-improved course, thanks in part to upgrades that enable it to generate hard x-rays for protein crystallography and other uses.
