Dark matter hunters of the LUX collaboration have ruled out a larger-than-ever range of properties that hypothetical dark matter particles might have had.

Researchers at SLAC have found a simple new way to study very delicate biological samples – like proteins at work in photosynthesis and components of protein-making machines called ribosomes – at the atomic scale using SLAC's X-ray laser.

View photos of upgrades and new equipment at the Stanford Synchrotron Radiation Lightsource (SSRL) that will enable scientists to study photosynthesis, superconductors and other fields of research.

SIMES scientists have discovered how to make the electrical wiring on top of solar cells nearly invisible to incoming light. The new design, which uses silicon nanopillars to hide the wires, could dramatically boost solar-cell efficiency.

The Gordon and Betty Moore Foundation has awarded $13.5 million for an international effort to build a working particle accelerator the size of a shoebox based on an innovative technology known as “accelerator on a chip.”

The medal, which recognizes distinguished physicists for outstanding statesmanship in science, honors Quinn for her work in science education.

Science wonderland at the San Francisco Giants ballpark draws a science-enthusiastic crowd of 35,000 visitors.

The SLAC Photowalk took a group of 17 photographers, both amateur and professional, behind the scenes to photograph SLAC's world-class science facilities, including the Linac Coherent Light Source (LCLS) X-ray laser and the Stanford Synchrotron Radiation Lightsource (SSRL).
