A collaboration between ORNL and software toolmaker Allinea Software has produced a formidable weapon in the fight against software application bugs. Data from DOE's ORNL on neutron interactions with isotopes of platinum contradict a basic assumption underpinning random matrix theory, nuclear physics models and quantum chaos. Ivaylo Ivanov of Georgia State University and colleagues used Jaguar, a Cray XT high-performance computing system at ORNL, to elucidate the mechanism by which accessory proteins called sliding clamps are loaded onto DNA strands and coordinate enzymes that enable gene repair or replication.
