To find a path around antibiotic resistance, a team working with the Intrepid supercomputer at Argonne National Laboratory is simulating molecular binding interactions to rapidly vet new infection-fighting candidates.

Speed kills, as the slogan says, and in computers what it kills could be disease. Argonne National Laboratory researcher Andrew Binkowski’s calculations of protein structure help find ligands – smaller molecules – that attach to them, to deliver drugs that stop dangerous infections. But without supercomputers it could take months to model a single ligand, […]
While others predicted when oil from the Deepwater Horizon spill in the Gulf of Mexico might reach beaches, ocean modelers at Los Alamos National Laboratory and the National Center for Atmospheric Research asked when gushing oil might exit the Gulf, where it would go and how diluted it’d be, up to a year later.
National Center for Atmospheric Research oceanographer Synte Peacock studies “the distribution of various tracers – something that tags a water mass and is carried around by ocean currents – to learn more about ocean circulation in the past and present.” These tracers include carbon and radiocarbon isotopes, paleotracers (fossils from the sea, in sediments and […]
If FASTER can be considered a jet that speeds global climate modelers to analyze fast physics processes, its wings are the testbed and associated research. The testbed integrates two major “fast” components: a single column model (SCM), a roughly 100 kilometer by 100 km column that complements traditional global climate models; and a numerical weather […]
