Computation helps evaluate the nature of the NIH research portfolio in ways that were previously very difficult.
What biomedical research does the federal government fund? How is it allocated across important diseases? Has that changed over time? Answering these questions at any level of detail is tougher than...

Several big-dollar initiatives received NIH funding in late 2010
In the current economic climate, every research dollar counts. Fortunately, when it comes to biomedical computing, not everyone has been left counting change. Several big-dollar initiatives received...

Advances in visualization changing work flows for understanding molecular dynamics, tracking cell movements, and designing interventional procedures
The pathway from raw data to valuable visualization of molecules, cells or organs being simulated over time involves several potentially painstaking steps. Typically, researchers must generate a set...

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...

Researchers are expanding the types of data that can be used to predict infectious disease spread; developing novel ways to analyze that data; and trying to create systems that can help address public health problems today
American officials are seeking better ways to anticipate public health crises following ten years that have seen outbreaks of SARS, avian flu, H1N1, West Nile virus, cholera and, most recently,...

HAP-SAMPLE takes real data as the template for simulations
Trying to find the genetic causes of a human disease requires lots of data. These days, researchers scan the genomes of people who do and don’t have a particular disease and look for genome-...

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...

Using computational models, researchers are gaining traction toward understanding what makes a stem cell a stem cell; how gene expression drives stem cell differentiation; why studying stem cell heterogeneity is important; and, ultimately, how stem cells control their fate.
To the casual observer, stem cells offer the almost magical promise of—Voila!—turning into exactly the kind of cell needed to repair an injured spinal cord or replace a damaged organ. And...

Having developed detailed and sophisticated models of both E. Coli and human metabolism, researchers can begin to build toward a whole cell model that will be useful for the study of human health and disease.
If biologists really understood the functioning of the genome, they could in principle recreate it in silico. Instead of a choreographed swirl of molecules inside a living cell, electrons...
