Queen's University computing professor sparks gamers' creativity at world renowned conference
Gamers don't just play Nicholas Graham's new video game, Liberi Live – they design it. While one player is rolling and bouncing a ball over obstacles and collecting coins another player can control the course design. The two interact together and with a touch of a button, obstacles or ramps can be added to completely change the game.

Scientists learn how to 'out run damage' with imaging technique
"From the beginning, the resolution of images recorded by biologists has been limited by damage due to the radiation used," said physicist John C. H. Spence, a Regents' Professor in physics at Arizona State University. "But what happens if a pulse of imaging radiation is used that terminates before damage begins, yet contains sufficient photons to generate a useful scattering pattern?"

Orthopaedic smart device provides personalized medicine
Imagine a smart sensor customized to provide vital, real-time information about a patient's recent orthopaedic surgery. Instead of relying on X-rays or invasive procedures, surgeons will be able to collect diagnostic data from an implantable sensor. A study presented at the Orthopaedic Research Society 2012 Annual Meeting in San Francisco outlined this remarkable technology that promises to make post-surgical diagnosis and follow up more precise, efficient, and cost-effective.
