Every experiment has to start somewhere. This one began with a container full of dying microbes, and the five cute, pink ciliates called blepharisma that James, our master of microscopes, accidentally turned into a group of cannibals.

We’re starting this episode out with a question that we’re never going to have a good answer for: how many cells do animals have? How could we ever hope to count all those cells in each of those animals? And how could we even begin to assume that the amount of cells in one individual is going to be the same for all the other individuals?

Somewhere around 470 million years ago, something happened that shouldn’t have been particularly striking. An algae found its way onto land. This algae turned the lands of this earth green, altered the chemistry of our atmosphere, and created homes for future life. This algae would give rise to all of the land plants we know of today.

When you’re in the business of hunting for microbes, sometimes you have to send some weird emails. That’s why James, our master of microscopes, sat down one day to send his own strange request to the people at Coralaxy, a coral farm in Germany.

We’ve spent most of our journey through the microcosmos seeking out the organisms that are too small to see with just the human eye. The bacteria, the ciliates, the tardigrades. Part of what makes them so exciting to find is that they are so tiny. Every moment we spend with one of these organisms is a peek into something exceptional in our experience of the world, and it’s the result of how much work James, our master of microscopes, has put into hunting down as many microbes as he can.

We’re going to see a type of motion over and over again because it’s all over the microcosmos, found in and around many different types of organisms. And this kind of random motion may seem almost too trivial to discuss, but this motion that you see is a proof of something fundamental not just to life, but to existence itself. This movement… is proof… of atoms.

For an activity that mostly involves sitting and staring, microscopy is a surprisingly high stakes task. On the other side of the lens are drops full of potential, a multitude of worlds to unravel and examine. But they’re also fragile worlds, easy to fracture and lose with just a tiny slip of the hand. The stakes only get higher when you’re dealing with an organism so rare that it’s only been reported a few times since it was first discovered in 1901.

You’ve heard those worm horror stories, right? Stories of painful stomach cramps or diarrhea or nausea that eventually turns out to be caused by some worms that have taken up residence in someone’s intestines. It’s so terrifying and wild to think of something so much smaller than us causing so much havoc. But, what if worms had to worry about their own guts being taken over by a parasite?

Tardigrades have been through a lot. They’ve been sent to the moon. They’ve had the moisture sapped out of them. At times, they’ve been in extreme heat. And at other times, they’ve had to contend with extreme cold. Well, today, we’ve got a new one for you. A harrowing journey for these tardigrades that have taken them through, what we assume, must be the worst thing that tardigrades have yet been subjected to. These poor, enduring tardigrades got stuck in postal security.

The ciliates we’re going to talk about today are kind of…frustrating. At this point in our journey, we’ve gotten used to the fact that the microcosmos is an indecipherable mess at times, filled with organisms that look like each other, and who have familial relationships that seem obvious but then turn out to be a figment of our own limited imaginations. And these ciliates are yet another entry in the long-standing saga of ever-changing taxonomies that define our understanding of microbial species. The plot twist is inevitable.

And he found that the bacteria were all swimming north.

As animals, we owe a lot to the single-celled organisms that came before us. These are the organisms that laid the chemical groundwork for how we live, from the DNA and proteins within them to the molecules they released into the environment. There’s something humbling about looking at our hands or feet and imagining the mixture of cells within them, and realizing the lessons that keep those cells bound together physically and biologically are rooted in a very ancient study in cooperation.
