Even in the microcosmos, it's important to stay inside if you want to avoid a virus.

What are microorganisms? They are microscopic organisms or tiny living things. Microorganisms can cause diseases, but in this video we are going to learn about how they are useful to us, specifically in making alcohol.

Everybody poops, but how does one poop when one does not have a butthole?

Death is inevitable and mysterious, even in the microcosmos. Stentors, heliozoans, and yes, even tardigrades, experience death in many different ways.

This is a world where microbes are both residents and food, which means that occasionally, we’ll have to spend our time together watching organisms, whose bodies are fractions upon fractions upon fractions of a millimeter in size, turn...

The family Spathidiidae is made up of around 20 genera, which encompass around 250 known species. And there’s a lot of variety in the Spathidiid family to sort through.

This week, we're diving back into the world of Stentors to find out what humans and Stentors have in common!<br/>

It's time to meet a single-celled organism that is bigger than a tardigrade! We'll learn how Stentors reproduce, why they look like trumpets, and why some of them are just SO BLUE!

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...

The goal of phylogenetic trees is to track the organisms we know of through their place in evolution.

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...

To study organisms at the genetic level, we need their DNA. Which means that we need to be able to wade through all the bits and pieces lying within their tiny bodies to pick out something even tinier—something we can’t just dig out with...

When there are over one trillion species, it can be hard to determine what you're looking at on your microscope. Thankfully we've got some helpful tips for you!

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...

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...

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...

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.

It’s often said that one person’s trash is another person’s treasure. And surely there is no greater proof of that than the home of our master of microscopes, James. All along the windowsills and bookshelves are jars and tanks full of...

We'd love to learn more about our Microcosmos community and who's out there watching these videos. So, we've got a short survey for you to fill out where you can let us know more about you and what you'd like to see from Journey to the...

Depending on your love of horror stories or your belief in the supernatural, it might be easy to convince you that lakes are full of ghosts. That as you plunge deeper into these lakes’ depths, you’ll come across translucent bodies that...

James, our master of microscopes, gets samples of sand from beaches all over the world to help in his quest to learn more about interstitial ciliates—the single-celled organisms that live in the watery pockets that exist between grains...

This video discusses the five major groups of microbes, including bacteria, fungi, protozoa, algae, and viruses. It provides examples of diseases caused by each group and emphasizes the importance of prevention and treatment measures....

Worms, despite their seemingly simple bodies, are a diverse bunch. Which is why we thought that for today, it might be fun to visit with a less famous worm, and like one of those relatives you don’t know very much about, but every time...

At first glance, they seem a bit more like plants or a series of flowers with thin, elegant petals. But no, they are indeed an animal. One that has the dubious honor of being defined largely by its anus.
