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.

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.

Five Years of Illumination: SLAC's Linac Coherent Light Source

Five years ago, the brightest source of X-rays on the planet lit up at SLAC. The Linac Coherent Light Source (LCLS) X-ray laser's scientific and technical progress since its momentous "first light" have been no less luminous, say those who have played a role in its success.
