T-Rex in the Slow Lane
by Kristen Cobb
Tyrannosaurus rex is often pictured baring its teeth, crouching, and running swiftly after its prey, but these images are largely based on human fancy...

Simulating molecular movement gives a more accurate view of binding sites.
If a picture’s worth a thousand words, then a motion picture, such as that provided by molecular dynamics (MD) simulations, must contain a wealth of information. It’s this potential...

OpenMM provides a common interface for doing MD simulations on GPUs
Over the last three years, the lab of Vijay Pande, PhD, at Stanford University has optimized their molecular dynamics (MD) algorithms to take advantage of the fast computing that’s possible...

Filling a gap in single molecule experimental work
Scientists sometimes find themselves up to their elbows in Styrofoam balls, pipe cleaners, and metal rods as they try to build models of the molecules they are studying. Now, they can exchange all...

For proteins, structure information leads to an understanding of function. The same turns out to be true for ribozymes, ribosomal RNAs, and some other recently discovered RNAs. But mapping out that...

OpenSim 2.0 promises greater opportunities for customization
With its initial release two years ago, OpenSim offered researchers a powerful open-source application for simulating movement. Simple enough to be used by high school students yet advanced enough to...
