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…

Fungal ‘Bouncers’ Patrol Plant-Microbe Relationship
By Stephanie Seay, ORNL A new computational framework created by Oak Ridge National Laboratory researchers is accelerating their understanding of who's in, who's out, who’s hot and who's not in the soil microbiome, where fungi often act as bodyguards for plants, keeping friends close and foes at bay. The research…

New Insights Into a Shapeshifting Protein Complex
Transcription factor IIH, or TFIIH, pronounced “TF two H,” is a veritable workhorse among the protein complexes that control human cell activity. It plays critical roles both in transcription — the highly regulated enzymatic synthesis of RNA from a DNA template — and in the repair of damaged DNA. But…

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…
