Scientists Line Up Unruly Gas Molecules for X-rays

It's hard to study individual molecules in a gas because they tumble around chaotically and never sit still. Researchers at SLAC overcame this challenge by using a laser to point them in the same general direction, like compass needles responding to a magnet, so they could be more easily studied with an X-ray laser.

X-ray Laser Maps Important Drug Target

Researchers have used one of the brightest X-ray sources on the planet to map the 3-D structure of an important cellular gatekeeper known as a G protein-coupled receptor, or GPCR, in a more natural state than possible before.

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.
