TechKnow 123: A machine keeps lungs breathing outside the body

TransMedics' proprietary Organ Care System technology allows for what they call a "living organ transplant," in which organs are kept warm and functioning while in transport to the recipient. Blood flows, hearts keep beating, lungs keep breathing. This allows for greater donor range and better organ viability than in traditional cold storage transplant methods.

The Shark Lab at the California State University at Long Beach is "dedicated to the study of the physiological and behavioral ecology of sharks, rays, and other economically important gamefishes." They use autonomous underwater vehicles (AUVs) to track leopard sharks and other animals off the coast of Southern California's Catalina Island.
