After two years of upgrades and repairs, proton beams once again circulate around the Large Hadron Collider at CERN. Oak Ridge National Laboratory has led an eight-year upgrade of the electromagnetic calorimeter used for LHC's experiment called ALICE (for A Large Ion Collider Experiment). This detector measures the energies of high-energy electrons and gamma rays to learn more about the conditions of the early universe.

Computational framework for optimizing traffic flow could be the beginning of a road revolution.

By studying fish and invertebrates in a creek with known mercury contamination, researchers are gaining a better understanding of the relationship between the toxin in the stream and bioaccumulation in organisms. While mercury concentrations in East Fork Poplar Creek in Oak Ridge, Tenn., have decreased significantly over the last 30 years, levels in tissue from fish have remained the same or increased. To understand why, a team led by Monica Poteat of Oak Ridge National Laboratory is examining the intricacies of the food chain and the biodiversity of the stream at locations about 10 kilometers apart.

A meeting to explore research collaborations between the Oak Ridge National Laboratory and the University of Tennessee set the foundation for a company that provides accessible and remote health screenings for patients concerned about diabetic related eye diseases.

For living organisms proteins are an essential part of their body system and are needed to thrive. In recent years, a certain class of proteins has challenged researchers' conventional notion that proteins have a static and well-defined structure.
