Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And so it's learned something specific about the way that you're poking it.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And there are other cells that can solve really complicated geometry problems, you know,

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

There's this famous ability of this slime mold called Fiserum to find the shortest path to connecting a bunch of different pieces of food.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And so when I look out in the world, I see all this complex decision making that these cells are capable of.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And I think about it on these behavioral timescales.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

So it's stuff that you can just directly observe under the microscope.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And so I think people are becoming increasingly interested in this idea, although it's not a new idea at all.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

Some of the earliest observations of these protists of microbes were describing these kinds of complex behaviors that I've been talking about.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And so there's actually a long history of people even thinking about cell psychology.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

We now know that cells don't have a brain.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

They are indeed single cells.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

But nevertheless, they have this

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

rich, diverse repertoire of behaviors and ability to make decisions that help them navigate diverse environments.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

And so there's just so much out there to learn.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

Yeah, thank you.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

This was so much fun.

Science Friday
Swords, cannibalism, poison: inside the world of killer microbes

Yeah, this was very fun.
