On this edition of TechKnow, contributor Dr Shini Somara follows a transplant team to understand how they rush into action whenever a donor organ becomes available.
We then explore a new technology which could be a game-changer in the organ retrieval process - a device that keeps lungs warm and breathing outside the human body, and which may eliminate time and distance factors from the organ transplant process.
Contributor Marita Davison, a biologist specialising in ecology and evolution, then joins researchers at Cal State University's shark lab who are developing a submersible robot that follows sharks and measures a range of enviromental conditions.
Davison takes a dip in the underwater lab and meets the waterproof robot that follows the elusive sea-creatures around, in an attempt to offer us a window into their natural behaviour.
