screen shot of the biomechanics of a knee
Aches and pains got you down? The way you walk could be wearing out parts of your body. With support from NSF’s Human-Centered Computing Program (HCC), Stanford University mechanical engineer Mark Cutkosky and his team are using volunteer test subjects to find out about one of the major problems at the root of knee pain--uneven wear and tear on the knee cartilage, which leads to arthritis. Cutkosky’s research, known as Movement Retraining, focuses on alleviating pain by analyzing and possibly changing a person's stride. Find out more in this Science Nation video.

students view a simulation of the human brain vasculature and cortical tissue in CAVE2
A team of neurosurgeons from the College of Medicine at the University of Illinois at Chicago (UIC) recently stepped into CAVE2--a next-generation, large-scale, virtual environment--to solve a vexing problem that presented itself in the arteries of the brain of a real patient. The method they used could someday benefit hundreds of thousands of Americans who fall victim to brain aneurysms and strokes, the third leading cause of death in the United States.

XROMM puts biomechanics on the fast track

New biomechanics visualization technology can be shared among scientists in open source database

The protective shells that have helped keep turtles around for millions of years have also kept scientists guessing about just what’s going on inside.

With support from the National Science Foundation (NSF), biologist Elizabeth Brainerd and her team at Brown University have developed X-ray Reconstruction of Moving Morphology, or XROMM, a new technology that combines CAT scan and X-ray technology for visualizing bones and joints in motion, in both animals and humans. Brainerd incorporates MAYA, the same animation software used to create high-end Hollywood special effects, to layer the XROMM images together to create 3-D visualizations.

XROMM has already transformed studies of vertebrate animal motion. In fact, the technology has proved such a useful tool that other labs are ramping up their own XROMM capability, and Brainerd is designing better software to meet the new demand. Her team is also putting together an open source database so researchers can quickly and easily share their visualizations.

Brainerd’s project will substantially enhance the cyberinfrastructure for comparative biomechanics research and increase U.S. economic competitiveness through technology development and advanced training of the scientific workforce.

The research in this episode was supported by NSF award #1262156, Collaborative Research: Advances in Biological Informatics (ABI) Development: Integrated X-Ray Motion Analysis Software and Video Data Management for the Comparative Biomechanics Community.
