Hitting molecules with two photons of light at once set off unexpected processes that were captured in detail with SLAC’s X-ray laser. Scientists say this new approach should work for bigger and more complicated molecules, too, allowing new insights into molecular behavior.

These inexpensive photosensitizers could make solar power and chemical manufacturing more efficient. Experiments at SLAC offer insight into how they work.

What they learned could lead to a better understanding of how ionizing radiation can damage material systems, including cells.

A new study uncovers how a critical protein binds to drugs used to treat asthma and other inflammatory diseases.
