TechKnow 105: Life after a face transplant & saving California's condors

After a brutal attack left her with burns over 80 percent of her body, Carmen Tarleton endured over 50 surgeries in five years before learning she was a candidate for a facial transplant. “I was stunned,” says Tarleton of learning what doctors had in mind. “I was shocked that this could even be done.”

After fighting her immune system's inital rejection of the new face, Tarleton's transplant was deemed a success. She does daily exercises to continue gaining control over her new facial muscles.

At the Institute for Conservation Research at the San Diego Zoo, scientists use GPS tracking systems to monitor behavior and flight patterns of the endangered condor population in Baja California.
