(Phys.org)—A team of researchers with UT Southwestern Medical Center and the University of Chicago has developed a new imaging technique that may give scientists a relatively simple means to unravel which parts of proteins ...
When light pulses from an extremely powerful laser system are fired onto material samples, the electric field of the light rips the electrons off the atomic nuclei. For fractions of a second, a plasma is created. The electrons ...
