John Currey from York University explains that it is almost impossible to make materials that are tough yet stiff: stiff materials tend to break easily and cannot absorb impacts. But not so dry deer antlers. Surviving impacts that are six times greater than crashes that shatter wet femur, deer antler is stiff enough to endure the dueling animals' pushing contests and could teach us how to make stiff, yet tough, materials. ...> Full Article
