How precise an image can fluorescence microscopy provide?
As modern optics and cell biology have flourished in recent years, they’ve each driven innovation in the other. Yet commonly employed imaging techniques, such as fluorescence microscopy, have...

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...

Metagenomes give a picture of the genes driving metabolic processes important to bacterial growth and survival in different environments.
We know they are there, but most microbial denizens of deep oceans, sea floor vents, even our own intestines, remain a mystery. Because most microbes won’t grow in the lab, researchers have few...

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,...

Multi-scale modeling is now at what might be called its gestational stage
For centuries, mathematics has been an indispensable ally of the physical sciences and engineering. Planes fly and telephones work because engineers know how to simplify physical systems into...

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...
