Computational simulation of the HIV-1 protease

Understanding HIV drug-resistance: A snapshot of the HIV-1 protease (a key protein that is the target for the protease inhibitor drugs) from a computational simulation. Mutations from the "wildtype" can occur within the active site (G48V) and at remote locations along the protein chain (L90M ). The "asp dyad" is at the centre of the active site, where polyprotein changes are snipped by the enzyme; this is the region that any drug must occupy and block.

Modeling Mantle Convection: A sequence of snapshots from a simulation of a model of the Earth's mantle showing a convection problem. Images depict rising temperature plume within the Earth's mantle, indicating the dynamically-evolving mesh required to resolve steep thermal gradients.
