How Bacteria Talk

I agree with Kevin, the TED talk Bonnie Bassler: Discovering bacteria's amazing communication system is a great talk.

She said "You think of yourselves as human beings, but I think of you as 90 to 95 percent bacteria".

Bonnie Bassler discovered that bacteria "talk" to each other, using a chemical language that lets them coordinate defense and mount attacks. The find has stunning implications for medicine, industry -- and our understanding of ourselves.
