Synchrotrons are used to study the atomic structure of materials. The second largest synchrotron is the Advanced Photon Source, located at the Argonne National Laboratory in Argonne, Illinois. The homepage provides information on the synchrotron and current research being conducted at the laboratory.

This site covers one of the top ten scientific breakthroughs of 1997, compiled in the December 19, 1997 issue of Science. The top scientific breakthrough of 1997 was the cloning of a sheep, resulting in a lamb named Dolly. The nine runners up were: the Pathfinder mission to Mars, synchrotrons, biological clock genes, gamma ray bursts, Neandertal DNA, nanotubes, Europa's ocean, whole genome sequencing, and neurons.
