For the first time, an ultraintense x-ray laser has revealed the previously unknown atomic-scale structure of a protein, researchers report online today in Science. The advance ushers in a new type of protein crystallography. However, it's too early to tell whether so-called x-ray free-electron lasers will supplant conventional x-ray sources known as synchrotrons, which have cranked out tens of thousands of protein structures, or merely serve niche applications, structural biologists say.
