Robotics Meet X-ray Lasers in Cutting-edge Biology Studies

Scientists at the Department of Energy’s SLAC National Accelerator Laboratory are combining the speed and precision of robots with one of the brightest X-ray lasers on the planet for pioneering studies of proteins important to biology and drug discovery.

Scientists Map Protein in Living Bacterial Cells

Scientists have for the first time mapped the atomic structure of a protein within a living cell. The technique, which peered into cells with an X-ray laser, could allow scientists to explore some components of living cells as never before.

X-ray Laser Measures Leaping Electrons

In an experiment at SLAC's X-ray laser, scientists split molecules into two fragments using pulses of infrared light, and then used X-ray pulses to observe the transfer of electrons.

X-ray Laser Gives Buckyballs a Big Kick

Scientists at SLAC have been blowing up "buckyballs" – soccer-ball-shaped carbon molecules – with an X-ray laser to understand how they fly apart. The results, they say, will help them interpret X-ray images of tiny viruses, individual proteins and other important biomolecules.
