LCLS Powers Chain Reaction of Light: A New Tool for X-ray Studies

Researchers have found a new way to probe molecules and atoms with an X-ray laser, setting off cascading bursts of light that reveal precise details of what is going on inside, which could allow scientists to see details of chemical reactions in a way not possible before.

Annual Synchrotron Award Goes to Longtime SSRL Scientist

Sean Brennan's decades of X-ray expertise keep pulling him back to SLAC even though he formally retired in 2008. During a recent visit to the lab, he accepted the Farrel W. Lytle Award for his extensive contributions to SLAC's Stanford Synchrotron Radiation Lightsource (SSRL).

Copper Shock: An Atomic-scale Stress Test

Scientists used the powerful X-ray laser at the U.S. Department of Energy's SLAC National Accelerator Laboratory to create movies detailing trillionths-of-a-second changes in the arrangement of copper atoms after an extreme shock.

X-ray Laser Explores New Uses for DNA Building Blocks

The founding father of DNA nanotechnology – a field that forges tiny geometric building blocks from DNA strands – recently came to SLAC to get a new view of these creations using powerful X-ray laser pulses.

For decades, Nadrian C. "Ned" Seeman, a chemistry professor at New York University, has studied ways to assemble DNA strands into geometric shapes and 3-D crystals with applications in biology, biocomputing and nanorobotics.

SSRL Confirms Anti-Flu Proteins Work as Designed

Understanding why proteins interact with certain specific molecules and not with the myriad others in their environment is a major goal of molecular biology. Now, in a series of recent papers, researchers describe how they designed proteins from scratch to have a high affinity and high specificity for targets on flu viruses, and then validated the two best designs using X-ray diffraction data collected at the Stanford Synchrotron Radiation Lightsource (SSRL).
