Molecular dynamics simulations spot alternative drug target
A blindside attack on HIV-1 protease might just combat drug-resistant strains of HIV, according to simulations run by researchers at the University of California, San Diego. When the simulations shut...

Disentangling the different types of skeptics and what modelers can learn from each.
What are the telltale signs of a modeling talk at a biology conference? Just look for the sighs, shifting, and eye-rolling in the audience, says Donald C. Bolser, PhD, professor of physiological...

How Simbios' state-of-the-art software tools are contributing to high-impact biomedical research
Simbios began with a simple idea: that physics-based simulation of biological structures at all scales could benefit from a
unified tool-building effort.
At the same time, the thinking went,...

Computing using time steps -- a necessary approximation
Time flows like a continuous, steady river. And it moves forward—never back. These facts create inherent challenges for computer simulations of biological molecules in motion.
It would...

Biologists have long taken gas exchange for granted, assuming that gases simply seep through the cell’s lipid membrane. Since 1998, however, evidence has been building that gases might also be...

Computational simulations of life in motion at every scale—molecular, cellular, tissue-level, and whole organism—are boosting our understanding of the role mechanics plays in controlling life.
From atoms and molecules to insects, dinosaurs, and humans, computational researchers are finding that much of life can be understood in mechanical terms. Indeed, the machines of life are...

Simulation of a one-million-atom virus reveals unexpected twist
Giving new meaning to the phrase computer virus, researchers have created a computer simulation of an entire biological virus comprising approximately one million atoms.
“It wasn’t...

Simbody introduces the concept of a “mobilizer,” which directly expresses a part’s movement, however complex, purely in relation to another part
Typically, researchers who simulate life in motion—from particles to people—start by describing the motion of each part of an object independently of the other parts. Additional equations...

Computational modeling can help fill gaps in how we develop and review new drugs and devices
What role does computational modeling play at the United States Food and Drug Administration (FDA)? If you ask Paul Watkins, MD, director of the Hamner—University of North Carolina...
