When physicians run out of treatment options, they look to a nascent field known as bioengineering for solutions to their patients' ailments. Specialized scientists apply engineering principles to biological systems, opening up the possibility of creating new human tissue, organs, blood and even corneas such as the one shown here. Waiting lists for organ transplants continue to be lengthy so the race to save lives with bioengineered body parts is on. Here’s a look at some of the most notable achievements in recent years.
