Twenty years ago, the idea of students doing homework online and receiving immediate feedback was a game-changer. Today, more than 700 colleges and high schools and using the WeBWorK system developed by Rochester math professors Arnold Pizer and Michael Gage.
Using the same mathematical framework as the Rochester Cloak, researchers have been able to use flat screen displays to extend the range of angles that can be hidden from view. Their method lays out how cloaks of arbitrary shapes, that work from multiple viewpoints, may be practically realized in the near future using commercially available digital devices.
Polymers that visibly change shape when exposed to temperature changes are nothing new. But a research team led by Chemical Engineering Professor Mitch Anthamatten has created a material that undergoes a shape change that can be triggered by body heat alone, opening the door for new medical and other applications.
“There’s an explosion of insect genome sequencing right now,” said Jack Werren, a professor of biology and a member of the research team. “But the bed bug is particularly interesting because it’s a human parasite, a major pest, and has a unique biology.”
