There will be a new face at Northern Arizona University (NAU) football games this fall – only the face of this new “team member” is a robot on wheels. Mayo Clinic researchers are working with NAU to test the feasibility of using a telemedicine robot to assess athletes with suspectedconcussions during football games.
With sophisticated robotic technology, use of a specialized remote-controlled camera system allows patients to be “seen” by the neurology specialist, miles away, in real time. The robot is equipped with a specialized camera system and remotely operated by a neurologist from the Mayo Clinic in Phoenix campus who has the ability to assess a player for symptoms and signs of a concussion, and to consult with sideline medical personnel.
The first time the robot will be used in a game is this Friday, Aug. 30, when NAU kicks off its season against…

Today, 19 January, is Popcorn Day, a day to celebrate one of nature’s fun foods – those crazy little corn kernels that, when exposed to heat, explode violently and morph into cushiony white snacks many times their original size.
We’ve all enjoyed popcorn, but have you ever wondered what makes ’em pop?
The secret to popcorn’s popping ability lies in the composition of the kernel. The popcorn kernel consists of a hard, watertight outer shell, containing starch and a small amount of water and oil.
When the kernel is heated, the water inside tries to expand to steam, but the hard shell prevents this. The heat also gelatinizes the starch inside the shell. Once sufficient pressure has built up (to an incredible 930 kPa), the kernel bursts open in a violent explosion, freeing the steam and starch.
As the hot starch bursts out of the shell, it expands rapidly…
