Physicists at SLAC and Stanford propose that the influence of cosmic rays on early life may explain nature’s preference for a uniform “handedness” among biology’s critical molecules.

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.

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.

Turning a brittle oxide into a flexible membrane and stretching it on a tiny apparatus flipped it from a conducting to an insulating state and changed its magnetic properties. The technique can be used to study and design a broad...

The giant cavity, in a protein that transports nutrients across the cell membrane, is unlike anything researchers have seen before.

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.

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...
