Simulations can teach us how young bodies and faces develop; how an artery compensates for decades of fatty plaque deposits by growing and thickening its walls; how tissue engineers can best coax endothelial cells to develop into organized sheets of skin for burn patients; and how cancerous tumors invade neighboring tissue.
For better or for worse, and on many levels, our tissues never stop growing and changing. While developing from childhood to old age, we grow not only bone, cartilage, fat, muscle and skin, but also...

Either/or molecular circuitry modeled
To differentiate or not to differentiate? That is the question constantly faced by embryonic stem cells. And they seem to answer it decisively at the behest of a molecular trio of transcription...

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...

Where simulation and theory converge
For decades, scientists have believed that DNA of short lengths (150 base pairs or fewer) behaves as a relatively stiff rod—able to quiver a bit, but rarely forming a circle or tight angle...

3D images help physicians design appropriate interventions.
Images of realistic and colorful 3D human body parts line the hall outside the lab. Blood and muscle look like blood and muscle; bone looks like bone. You almost expect to find human cadavers being...

The fittest organisms survive and produce offspring, according to the Darwinian theory of natural selection. And the changes that make an organism fit happen at the molecular level: when genes mutate...

An opportunity and a challenge
When discussing biocomputation startups, there’s one thing people agree on: These days, they don’t generate much excitement among venture capitalists.
“In the 1990s, there...

Computer models find that various ion channel arrangements can produce the same firing pattern
Each cell in our nervous system is an instrument in a complex symphony of electrophysiologic communication. A neuron’s signaling abilities arise from its array of ion channels—tunnels...

An elegant new model of balance control suggests the brain only cares about one thing: the body’s center of mass.
Bumped from behind, a person may step forward to avoid falling. Perhaps her arms fly out as well. To the untrained eye, these movements seem like the result of the brain controlling individual nerve...
