Something in the Water Does Not Compute
Computational scientists at the Department of Energy’s Oak Ridge National Laboratory have published a study in the Journal of Chemical Theory and Computation that questions a long-accepted factor in simulating the molecular dynamics of water: the 2 femtosecond (one quadrillionth of a second) time step. The femtosecond is a timescale…

ORNL Supercomputing Resources Support Simulation of Influenza Virus Showing Universal Vaccine Promise
According to the World Health Organization, each year influenza infects an estimated 1 billion people worldwide. Between 3 and 5 million of these cases are severe, and up to 650,000 cases result in influenza-related respiratory deaths. Seasonal flu vaccines are reformulated each year to match the dominant strains, and when…
