Q&A: Biologist describes milestone in watching proteins boogie

Using an X-ray laser at the Department of Energy's SLAC National Accelerator Laboratory, researchers have for the first time directly seen myoglobin move within quadrillionths of a second after a bond breaks and the protein releases a gas molecule. The Linac Coherent Light Source X-ray laser is a DOE Office of Science User Facility, and its short, bright pulses were essential for observing these ultrafast, atomic-scale motions.

Time-lapse analysis offers new look at how cells repair DNA damage

Time-lapse imaging can make complicated processes easier to grasp. Berkeley Lab scientists are using a similar approach to study how cells repair DNA damage. Microscopy images are acquired about every thirty minutes over a span of up to two days, and the resulting sequence of images shows ever-changing hotspots inside cells where DNA is under repair.
