You can find bacteria everywhere. They're invisible to us. I've never seen a bacterium, except under a microscope. They're so small, we don't see them, but they are everywhere.

Most bacteria aren't bad. We breathe and eat and ingest gobs of bacteria every single moment of our lives. Our food is covered in bacteria. And you're breathing in bacteria all the time, and you mostly don't get sick.

What's great about bacteria is you have a surprise every day waiting for you because they're so fast, they grow overnight.

I think the easiest application to help people understand what quorum sensing is and why it's important to study is to tell them that if we could make the bacteria either deaf or mute, we could create new antibiotics.
