SLAC Research Reveals Rapid DNA Changes that Act as Molecular Sunscreen

Even in their infancy, X-ray lasers such as SLAC's Linac Coherent Light Source are notching a list of important discoveries, and a special issue of a scientific journal highlights their unique contributions to biological sciences.

By finding surprising similarities in the way immune system defenders bind to disease-causing invaders, a new study may help scientists develop new treatments.

Researchers have discovered that an Ebola virus protein can transform into three distinct structures with different functions. This rather uncommon property provides new clues for the development of potential drugs for deadly hemorrhagic fever.

Given a year to mature, the Institute for Chemical Biology is relaunching under a new name that better reflects its vision of bringing Stanford's unique interdisciplinary culture to bear at a new frontier of chemistry.

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...

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 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...

A 2-ton instrument the size of a compact car, now available at SLAC's X-ray laser, makes it possible to capture more detailed images of atoms, molecules, nanoscale features of solids, and individual particles such as viruses and airborne soot.

New Technology Allows Faster, More Accurate Imaging of Hard-to-study Membrane Proteins

A study shows for the first time that X-ray lasers can be used to generate a complete 3-D model of a protein without any prior knowledge of its structure.
