New release improves both GUI and API
OpenSim, the neuromuscular modeling and simulation software, is now available in a new digit: 3.0. The change (up from 2.4) reflects significant improvements that make this open source tool more...

Biomechanical models contribute to a better understanding of both the normal and the diseased eye.
Squint, and you can almost make out that bird soaring over the horizon. But determining whether it’s a hawk or a raven will be nearly impossible for someone with myopia, also known as...

Moving from intuition to evidence-based intervention
To understand how muscles contract and joints flex, researchers have dissected cadavers and experimented with animals. They can describe how bones, muscles, and tendons connect in a complicated...

To understand biology—and provide appropriate medical care—scientists need to understand interactions across multiple scales. Hence the Physiome.
This is the reality of human biology: events span a 109 range in lengthscale (molecular to organismal) and a 1014 range in timescale (molecular movement to years). To understand this biology—...

T-Rex in the Slow Lane
by Kristen Cobb
Tyrannosaurus rex is often pictured baring its teeth, crouching, and running swiftly after its prey, but these images are largely based on human fancy...

Even when we simply stand still on two feet, our brains communicate with our muscles—firing them appropriately to keep us upright against gravity. So when scientists simulate simple or complex...

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,...

Using software designed for stress testing in engineering, researchers have modeled an American sabercat's skull in the highest resolution vertebrate animal model to date.
Wildlife biologists can watch a lion stalk its prey, but paleontologists must examine fossils to understand how the extinct saber-toothed cat hunted. Researchers now have modeled an American sabercat...

Unlike most classical engineering materials, biological tissues can adapt to external stimuli by growing in volume: Skin grows in response to wounding; muscles grow in response to exercise; cancer...

A three-dimensional biomechanical model predicts how effectively functional electrical stimulation (FES) stabilizes seated postures
Implanting electrodes into paralyzed torso muscles can help individuals with spinal cord injury balance in their seats. So say researchers at Case Western Reserve University, who have built a three-...
