Computer-equipped dogs lead way in search-and-rescue

submitted by: nsf
Researchers from North Carolina State University (NCSU) showed off pioneering work demonstrating the potential of technologies that allow dogs to gather information, and stay safe, during search and rescue operations. Among the applications they're testing are computer-assisted training, remote communication with dogs in the field and tools to help people with guide dogs better understand what their dogs are doing. They accomplish these tasks by equipping dogs with video, audio and gas...

Science Behind the News: Predictive Policing

submitted by: nsf

"The Los Angeles Police Department is using a new tactic in their fight against crime called “predictive policing.” It's a computer program that was originally developed by a team at UCLA, including mathematician Andrea Bertozzi and anthropologist Jeff Brantingham. “Science Behind the News” is produced in partnership with NBC Learn.

- Rebuilding the world one pixel at a time - Who says Rome wasn't built in a day? With the muscle of about 500 computers and 150,000 still images, Steve Seitz, a professor in the Department of Computer Science and Engineering at the University of Washington's Seattle campus, and his colleagues have reconstructed many of Rome's famous landmarks in just 21 hours.

Science Nation - Science of Shopping

submitted by: nsf
Go into any grocery store and cameras may be watching you. These cameras are not looking for thieves, they're looking for shoppers! The cameras are focused on the tops of peoples' heads (so it's anonymous), but they don't have to see faces to track which store aisles get the most traffic and how long consumers spend looking over products. With support from the National Science Foundation, computer scientist and CEO of VideoMining Rajeev Sharma and his team have designed software that...

Science Nation - Geo-Immersion

submitted by: nsf
Imagine a virtual computer simulation that reflects the world around you in real-time. Before you ever leave your home, a wealth of images and information about the world around you is at your finger-tips. Facial recognition might give information about the location of your friends, or maybe you want the latest scoop about the specials at local restaurants, or the real time locations and estimated arrival and departures of commuter trains. According to the Integrated Media Systems Center...

Science Nation - Music and Creativity

submitted by: nsf
Georgia Tech's Parag Chordia believes music is a universal part of human culture, and his research shows music education can inspire greater interest in math, physics, and computer science. Chordia heads Georgia Tech's "Music Intelligence Group." With support from the National Science foundation, his goals are to program computers to understand music the way humans do naturally - anticipating what is coming next. He's also studying changes in the brains of professional musicians as they play...

Science Nation - Super Stars

submitted by: nsf
Who are the biggest super stars in the universe? For Adam Burrows, an astrophysics professor at Princeton University, it's not who, but "what," and they are far from Hollywood, or even earth, for that matter. Burrows would tell you biggest super stars are the stars that die in a massive explosion called a "supernova." With support from the National Science Foundation, Burrows investigates supernovae and he has recently created 3D computer simulations showing the actual moment of a star's...
