Scientists Map Protein in Living Bacterial Cells

Scientists have for the first time mapped the atomic structure of a protein within a living cell. The technique, which peered into cells with an X-ray laser, could allow scientists to explore some components of living cells as never before.

Catching Chemistry in Motion

SLAC researchers have developed a laser-timing system that could lead to X-ray snapshots fast enough to reveal the triggers of chemical and material reactions.

X-ray Laser Measures Leaping Electrons

In an experiment at SLAC's X-ray laser, scientists split molecules into two fragments using pulses of infrared light, and then used X-ray pulses to observe the transfer of electrons.

X-ray Laser Gives Buckyballs a Big Kick

Scientists at SLAC have been blowing up "buckyballs" – soccer-ball-shaped carbon molecules – with an X-ray laser to understand how they fly apart. The results, they say, will help them interpret X-ray images of tiny viruses, individual proteins and other important biomolecules.

A New Way to Create Compact Light Sources

SLAC scientists have found a new way to produce bright pulses of light from accelerated electrons that could shrink "light source" technology used around the world since the 1970s to examine details of atoms and chemical reactions
