The "Gangnam Style" Craze Continues

The Robotics and Mechanisms Laboratory at Virginia Tech released one of the newest viral videos demonstrating the popular "Gangnam Style"-in the form of a robot. Tech developed the humanoid robot as a research platform to study walking and independent behaviors within the robot community. The video was posted by The Robotics & Mechanisms Laboratory (RoMeLa), which explained:

It is designed to be ultra light weight (under 15 kgs) for safety and low cost. As the next generation of the CHARLI series humanoid robots, CHARLI-2 improves stability and speed in walking, intelligence and autonomy, and soccer playing skills. CHARLI-L2 is also designed to participate in the autonomous robot soccer competition, RoboCup, in the Adult size league."

Kateri Tekakwitha was named the first Native American saint today by Pope Benedict XVI in a ceremony held in St. Peter's Square. The 17 th century Mohawk-Algonquin was credited, more than 300 years after her death, with miraculously healing a young boy who was near death with a flesh eating bacteria. That attributed miracle paved the way for Kateri's canonization. She is one of seven people canonized in the Vatican ceremony today.

NASA's Curiosity Rover Finds More Objects on Mars

Nasa's "Curiosity" rover found new objects on Mars last week that officials say could be native to the planet.

After the rover spotted a few shiny during its daily sweep, NASA sent commands to Curiosity Monday to take a third sample of soil from Mars to learn more about the objects.

"Confidence for going ahead with the third scooping was based on new assessment that other bright particles in the area are native Martian material," NASA said in a statement. "One factor in that consideration is seeing some bright particles embedded in clods of Martian soil."
