Concussions have become a huge concern in contact sports in recent years. My cousin Ryan (who runs SportsSuperStation.com) suffered multiple concussions in Hockey which had some scary lasting effects, and forced him to quit sports for a while. Shockbox helmet sensors for concussion management were recently featured on CBC's Dragons' Den. They've got a solid demo video now too. After you watch the video below, read what happened after the show.

Arthritis and injury grind down millions of joints, but few get the best remedy - real biological tissue. Kevin Stone shows a treatment that could sidestep the high costs and donor shortfall of human-to-human transplants with a novel use of animal tissue.

The use of animal tissue will stir up controversy. Compare this to eating meat almost daily though. It seems more humane to use a small amount of animal tissue for fixing ourselves only a few times in our entire lives. We kill/harvest so many animals already, they could use the parts from those animals more wisely.
