Collaboration of a Different Kidney
Collaborating for mutual benefit lies at the heart of open source, but not quite as profoundly as in this situation:
US doctors have carried out what is believed to be the world's first simultaneous six-way kidney transplant.
Six recipients received organs from six donors in operations at the Johns Hopkins Hospital in Maryland.
The procedure was made possible after an altruistic donor - neither a friend nor relative of any of the six patients - was found to match one of them.
Five patients had a willing donor whose kidney was incompatible with theirs, but it did match another in the group.
This meant that suddenly, there were six people who could receive an organ.
