An experiment at the Department of Energy鈥檚 SLAC National Accelerator Laboratory provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity 鈥� a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
Researchers have captured the highest-resolution snapshots ever taken with an X-ray laser that show changes in a protein鈥檚 structure over time, revealing how a key protein in a photosynthetic bacterium changes shape when hit by light. They achieved a resolution of 1.6 angstroms, equivalent to the radius of a single tin atom.
An important study conducted in part at the Department of Energy鈥檚 SLAC National Accelerator Laboratory may lead to new, more effective vaccines and medicines by revealing detailed information about how a flu antibody binds to a wide variety of flu viruses.
Several experiments, including the BaBar experiment at the Department of Energy's SLAC National Accelerator Laboratory, have helped explain some 鈥� but not all 鈥� of the imbalance between matter and antimatter in the universe. Now a SLAC theorist and his colleagues have laid out a possible method for determining if the Higgs boson is involved.
Scientists have found the first direct evidence that a mysterious phase of matter known as the "pseudogap" competes with high-temperature superconductivity, robbing it of electrons that otherwise might pair up to carry current through a material with 100 percent efficiency.
Researchers working in part at the Department of Energy鈥檚 SLAC National Accelerator Laboratory have discovered that a key protein for cell health, which has recently been linked to diabetes, cancer and other diseases, can multitask by having two identical protein parts divide labor.
Bacteria have a sophisticated means of defending themselves, and they need it: more viruses infect bacteria than any other biological entity. Two experiments undertaken at the Department of Energy's SLAC National Accelerator Laboratory provide new insight at the heart of bacterial adaptive defenses in a system called CRISPR, short for Clustered Regularly Interspaced Short Palindromic Repeat.
Scientists have used an X-ray laser at the Department of Energy鈥檚 SLAC National Accelerator Laboratory to get the first glimpse of the transition state where two atoms begin to form a weak bond on the way to becoming a molecule.
Researchers working at the Department of Energy鈥檚 SLAC National Accelerator Laboratory have captured the first X-ray portraits of living bacteria. This milestone, reported in the Feb. 11 issue of Nature Communications, is a first step toward possible X-ray explorations of the molecular machinery at work in viral infections, cell division, photosynthesis and other processes that are important to biology, human health and our environment.
Researchers have long sought alternatives to morphine 鈥� a powerful and widely used painkiller 鈥� that curb its side effects, including dependency, nausea and dizziness. Now, an experiment at the Department of Energy鈥檚 SLAC National Accelerator Laboratory has supplied the most complete atomic-scale map of such a compound docked with a cellular receptor that regulates the body鈥檚 pain response and tolerance.
