Increasing the spatial resolution of X-ray microscopy.

A Swiss team’s new scanning and diffracting technique may one day dramatically increase the spatial resolution of X-ray microscopy. Pierre Thibault and colleagues at the Paul Scherrer Institut in Villigen, Switzerland, developed the method to bridge the gap between coherent diffractive imaging, which is a computationally intensive procedure, and scanning transmission X-ray microscopy, which limits resolution to the beam-spot size on the sample under study (Science 321, 379).
