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.

X-ray studies conducted at SLAC and in the United Kingdom have resurrected the detailed chemistry of 50-million-year-old leaves from fossils found in the western United States and found striking similarities to their modern descendants.
A composite optical and X-ray image (red is copper, green is zinc, blue is nickel) of a 50-million-year-old leaf fossil. Trace metals correlate with the leaf's original biological structures. Also visible are ancient caterpillar feeding tubes.

A new tool for analyzing mountains of data from SLAC’s Linac Coherent Lightsource (LCLS) X-ray laser can produce high-quality images of important proteins using fewer samples. Scientists hope to use it to reveal the structures and functions of proteins that have proven elusive, as well as mine data from past experiments for new information
