One month from today--July 1st, 2012--is the deadline for the newest InnoCentive challenge. We're looking for suggestions for new applications of a brand-new, unique material, a cementitious calcium carbonate that is remarkably strong and easy to use. It's got some great potential in architecture, ceramics, physical sciences, life sciences, and pharmaceuticals. There's a guaranteed award on this one, which is great--the best suggestion will receive a prize of $7,000. It's a great challenge, and one really well-suited for you guys--we know there are some great brains out there reading this, and we'd love to see some killer PopSci entries. Read more about it over at InnoCentive.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
