Understanding why proteins interact with certain specific molecules and not with the myriad others in their environment is a major goal of molecular biology. Now, in a series of recent papers, researchers describe how they designed proteins from scratch to have a high affinity and high specificity for targets on flu viruses, and then validated the two best designs using X-ray diffraction data collected at the Stanford Synchrotron Radiation Lightsource (SSRL).
Scientists studying neutrinos have found with the highest degree of sensitivity yet that these mysterious particles behave like other elementary particles at the quantum level. The results shed light on the mass and other properties of the neutrino and prove the effectiveness of a new instrument that will yield even greater discoveries in this area.
After months of installation and commissioning efforts, SLAC's newest user facility welcomed its first two groups of experimenters on Friday. They came to use the tightly focused electron bunches delivered by FACET, the Facility for Advanced Accelerator Experimental Tests, for two very different purposes.
Menlo Park, Calif. — A 3.2 billion-pixel digital camera designed by SLAC National Accelerator Laboratory is now one step closer to reality. The Large Synoptic Survey Telescope camera, which will capture the widest, fastest and deepest view of the night sky ever observed, has received “Critical Decision 1” approval by the U.S. Department of Energy (DOE) to move into the next stage of the project.
Scientists have found a way to distort the atomic arrangement and change the magnetic properties of an important class of electronic materials with ultra-short pulses of terahertz (mid-infrared) laser light without heating the material up. While the achievement is currently of purely scientific interest, the researchers say this new approach control could ultimately lead to extremely fast, low-energy, non-volatile computer memory chips or data-switching devices.
