Supercomputing the emergence of material behavior  

Chemists have designed the first artificial protein assembly (C98RhuA) whose conformational dynamics can be chemically and mechanically toggled. The Maverick GPU-based supercomputer at the Texas Advanced Computing Center simulated the system through an allocation on NSF-funded XSEDE, the Extreme Science and Engineering Discovery Environment. The research could help create new materials for renewable energy, medicine, water purification, and more.
