I always think nature does it best. It has billions of years of experience!

Synthetic biologists harness nature's know-how and grow materials from cells. A team at MIT have genetically engineered bacteria to make them grow even more complex structures such as electrical switches. I'm excited - making materials biologically creates less waste and could change the way we manufacture things in the future.
