Biologists and ecologists monitor wildlife to learn more about their behaviors, but tracking small creatures can be challenging, time-consuming and costly. Through a National Science Foundation grant, a multidisciplinary team at Northern Arizona University—led by Michael Shafer, associate professor of mechanical engineering; Carol Chambers, professor of wildlife ecology; and Paul Flikkema, professor of electrical engineering—has developed… Read more

Every day, Americans rely on engineered systems such as bridges, buildings and offshore structures that are subject to extreme weather, earthquakes and a range of other conditions. Knowing how materials used in these systems respond to stressors is crucial to creating components that successfully and efficiently do the job.
Engineers rely on mathematical… Read more
Nearly 4 children in 1,000 are afflicted with cerebral palsy (CP), making it the most common cause of pediatric physical disability in the U.S. This neurological disorder, typically caused by damage to the brain before birth, affects a child’s muscle control and coordination and often makes walking extremely difficult. What’s more, children… Read more
In the field of muscle physiology, scientists study muscle movement at the molecular level—chiefly, proteins such as myosin, actin and titin—to understand how muscles contract.
Their research improves human health and quality of life in a wide range of areas, including rehabilitation engineering, prosthesis design and the treatment of neuromuscular diseases such as muscular dystrophy, which causes progressive… Read more
According to the American Heart Association, cardiovascular disease remains the leading cause of death in the U.S.—higher than all forms of cancer and lung disease combined. Hemodynamics, how blood circulates throughout the body, are believed to play a major role in the progression of heart disease.
One of… Read more
What if an electric car could be run off the power stored in its door panels? What if a jet could be powered by energy stored in its fuselage?
Researchers at Northern Arizona University have invented a unique multifunctional material that is capable of storing power while providing structural support for high-performance systems operating in a wide range of environments specific to the aerospace, automotive… Read more
