Third Place - Mark McClendon

When a newt loses part of its tail or leg, it is able to regrow the missing piece through a process called tissue regeneration. Humans do not naturally regenerate tissues, but scientists, like McClendon and his colleagues, are developing ways to grow new tissues in the lab. In the near future, artificial arteries made from the materials they create could be used in bypass heart surgeries.

In this image, small spheres of polylactic acid (orange) are randomly dispersed on the surface of a salt crystal (blue) to create foam that can be molded into artificial blood vessels.
