Revealing both sides of the story in a single experiment has been a grand scientific challenge.

Understanding nature’s process could inform the next generation of artificial photosynthetic systems that produce clean and renewable energy from sunlight and water.

Learning how liquid silicates behave at these extreme temperatures and pressures has been a longstanding challenge in the geosciences.

The advance opens a path toward a new generation of logic and memory devices that could be 10,000 times faster than today's.

Siegfried Glenzer's team and collaborators from Tel Aviv University are working on a method that could make proton accelerators 100 times smaller without giving up any of their power.

Light-driven reactions are at the heart of human vision, photosynthesis and solar power generation. Seeing the very first step opens the door to observing chemical bonds forming and breaking.

It combines human knowledge and expertise with the speed and efficiency of “smart” computer algorithms.

New research shows that when a bunch of electrons zooms through the middle of a ring-shaped laser beam, the bunch can wind up with higher quality and generate a brighter X-ray beam.

Researchers investigate how much damage spreads through molecules struck by a pulse from LCLS.

This new technology could enable future insights into chemical and biological processes that occur in solution, such as vision, catalysis and photosynthesis.

An LCLS imaging technique reveals how a mosquito-borne bacterium deploys a toxin to kill mosquito larvae. Scientists hope to harness it to fight disease.

A better understanding of this phenomenon, which is crucial to many processes that occur in biological systems and materials, could enable researchers to develop light-sensitive proteins for areas such as biological imaging and optogenetics.
