Asteroid Deflection
An Asteroid Deflection Research Center has been established on the Iowa State campus to bring researchers from around the world to develop asteroid deflection technologies.
“In the early 1990s, scientists around the world initiated studies to assess and devise methods to prevent near-Earth objects from striking Earth,” says Bong Wie, the Vance D. Coffman Chair Professor in Aerospace Engineering and director of the center. “However, it is
Replacing Bone Fragments
In traumatic accidents, broken bones can be reduced to bone fragments, sometimes leaving a void in the bone structure that needs to be filled. IMSE Assistant Professor Matt Frank is investigating the use of a subtractive rapid prototyping process called CNC-RP to reverse-engineer replacement bone fragments from medical imaging such as CT scans. The research could impact the effectiveness of orthopedic surgery for traumatic bone fracture, as custom
Shining Light on Policy & Panels
When talk turns to energy and its related issues—cost, availability of resources, the potential of alternatives—what becomes clear is that clarity itself is at a premium. Agreement on any single aspect of our energy present or energy future is elusive, in part because complex questions defy simple answers.
Understanding the technology is difficult enough, and the science is obscured by political partisanship, special-interest agendas, and common misperceptions. Sifting for reliable, objective
