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.
When antibiotics first came out, nobody could have imagined we'd have the resistance problem we face today. We didn't give bacteria credit for being able to change and adapt so fast.
My bacteria glow in the dark - no human being doesn't like that.
We've all been sick; we're all afraid of infection. 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.
Bacteria mineralized the rocks; they deposited the iron. They made the geology we see.

If a bacterium is trying to infect you, it won't secrete alone, because your immune system will block it. Bacteria will hide until they can all act together and make an impact.
All these bacteria that coat our skin and live in our intestines, they fend off bad bacteria. They protect us. And you can't even digest your food without the bacteria that are in your gut. They have enzymes and proteins that allow you to metabolize foods you eat.
It's incorrect to think of bacteria as these asocial, single cells. They are individual cells, but they act in communities, exactly the way people do.
