If you know about the species Lacrymaria olor, then you know what you’re getting when you see it under a microscope. It has a distinct shape, a distinct way of life—the combination of its own genetics and its surrounding environment.

James, our master of microscopes, recently received a package from a coral farm in Germany. We’ve explored some of the microscopic creatures and bristle worms that were living and thriving in those packages in previous videos. But today...

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...

This is kentrophoros, a ciliate that James—our master of microscopes—had been searching for, receiving samples from all over the world in the hopes of finding it gliding around. When you first look at it, it doesn’t seem particularly...

If you’ve ever wondered what it might take to upset a microscopist, just ask James—our master of microscopes—his feelings about tardigrade legs. Yes, tardigrade legs. Those chunky, wiggly limbs that move their owner through meals of moss...

If you’ve been following James, our master of microscopes, on some of his other platforms, then you know what’s coming. You know that James has published his first academic paper, it's about this extraordinarily rare ciliate that you...

Sometimes our journey through the microcosmos feels like an expedition, a voyage filled with deep dives into the masses of organisms basking under the glow of our microscope. So what does it mean when you don’t find anything. When you...

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...

James, our master of microscopes, is not a farmer. He is, to put it simply, fascinated by microbes. And that may lead him to strange places and cause him to grow tanks full of weird things. But he is not a farmer.

The theme of today's episode is pretty simple: things we never thought we’d be showing you, but here we are.

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...

When we look at bacteria under a microscope, they appear to be tumbling around chaotically, but over the centuries we realized that their pathways have a purpose.

We recently discovered some Holospora infecting one of our Paramecium samples. How does that happen? How does the Holospora get in there? And how are they so successful at infecting?

There are only a few groups of bacteria that do this kind of gliding, but they’re found across a plethora of environments, including ponds, soil, and, surprise, in our own mouths.

From trumpets and spirals to floral arrangements, single cell organisms take on many strange and unique shapes. But they don't look like that just for fun, their shapes can help them with movement, hunting, and even defending themselves.

The Complicated Relationships of the Microcosmos

Leeuwenhoek: The First Master of Microscopes

Rotifers don’t really get a lot of love when it comes to microscopic animals. At least as far as the public imagination goes, the rotifer is overshadowed by its fellow metazoan of the microcosmos: the tardigrade. And we might be part of...

After over three years of searching for it, our Master of Microscopes has found a Spirostomum semivirescens!

As strange as the creatures of the microcosmos are, their lives still revolve around the same fundamentals that ours do. There’s food, reproduction, and death. Yes, even microbes, hardy as they can be, experience death. In some ways,...
