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...

Computers and human experts duke it out over who is better at diagnosing disease, interpreting images, or predicting protein structure
Dorothy Rosenthal tenses over her microscope, peering at the problematic nucleus on the Pap smear yet again. “It’s abnormal,” she decides, and then hesitates. “No, it’s...

There is growing recognition that epigenetics may be just as important as genetics in human health and disease.
In the early 19th century, Jean-Baptiste Lamarck explained evolution as the inheritance of acquired traits; he believed that changes due to behaviors and exposures in one generation could be passed...

The edict that academics must “publish or perish” serves not merely to advance careers, but also to stress the importance of transmitting knowledge from scientist to scientist and...

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...

From hardened software to scientific productivity, the NCBCs have changed the landscape for biomedical computing. What will happen when their funding expires?
It has been eight years since the National Institutes of Health (NIH) funded the first National Centers for Biomedical Computing (NCBCs). With two or three years remaining in the program (...

Modelers are using recent gains in computational power to consider the complex interactions of hundreds or thousands of macromolecules at once--a necessary first step toward whole cell simulation
Molecules in cells behave like people in crowded subway cars. Because they can barely budge or stretch out without bumping into a neighbor, they move more slowly, smush themselves into more compact...

By computationally combining incomplete imaging information with bits and pieces of structural data from all sorts of different experiments, researchers have worked out the protein-by-protein structure of an important cellular assembly called the nuclear pore complex.
Like puzzles? Here’s a tough one: Try figuring out the construction of a nearly 500-piece machine without blueprints or a complete picture. Biologists have now accomplished just such a feat,...

Working in silico, researchers hone in on candidate proteins worthy of laboratory work
By stringing together amino acids in a prescribed sequence that then folds into a defined structure, nature designs proteins to perform specific functions. Nowadays, computational researchers are...

Assuring accuracy and efficiency
In simulations of human activities such as running, hundreds of individual musculotendon models turn on and off to swing the arms and legs. Naturally, these simulations can only be as accurate and...
