2-D simulation shows angiogenesis as it happens
Microscopic capillaries grow on demand, snaking toward hungry cells needing their blood supply. Understanding how to control this process could help scientists promote wound healing or halt cancer in...

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...

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...

Bringing models closer to reality
When the ill-fated space shuttle Columbia launched on January 16, 2003, a large piece of foam fell off and hit the left wing. Alerted of the impact, NASA engineers used a computer model to predict...

How cell-centered models are adding fundamental insights into our understanding of cell behaviors
The cell is like our financial system: Even if you have a diagram of all the complex interactions going on, you still cannot intuit how the whole system will react when perturbed. Indeed, the cell...

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...

New approaches extend multiscale models to represent cellular mesoscales and bridge from molecular to cellular models
In an era of increasingly comprehensive molecular characterizations of living systems, computation has emerged as a key technology to facilitate integrative understanding of biological mechanisms....

The complexity and variability of aging itself, along with the fragmented nature of researchers’ current understanding of aging, call for tools that can help scientists dig through mounds of data to find often subtle connections.
Jeanne Louise Calment of Arles, France rode a bicycle until she was 100 years old. When she gave up smoking at age 117, her doctor suspected it was out of pride. (She couldn’t see well enough...

How errors in data, software, and methodology can teach us how to do better
In 2006, a paper in Nature Medicine suggested a novel and potentially revolutionary method for predicting patient responses to cancer therapies using gene signatures. The finding piqued the interest...
