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.
