Recent research by aerospace engineer Herzl Chai of Tel Aviv University revealed that the structure of human and otter teeth could spell safer airplanes. Human and otter molars are apparently quite similar in structure. They are comprised of layer upon layer of wavy fibers that are durable and can withstand quite a lot of wear and tear. Current airplane technology uses a gridlike structure of glass and carbon fiber materials. If planes were designed with a wavy structure, instead of the gridlike structure airplanes might not break up in crashes so badly.
Again- Mother Nature is the best model.
