An amazing piece on the CBC about synthetic biology and the amazing things that humans are working on creating such as entirely new life forms geared toward doing new functions for us.
Such things as microbes that eat pollution, bugs that go into our body and eat cancer, plastic manufacturing microbes, or carbon eating bugs that piss straight diesel fuel, and how about taking some cells from a human body and using microbes to grow and print a replacement heart for a patient.
