A video entitled “Cells: How Can Something Small Have a Large Impact?” which explores the two types of cells and how they function to create and affect life in a variety of ways.

Science is built on questions. So let’s start today with one: what do you think happens when you set off an electrical spark in the microcosmos?

If we had to nominate an ambassador to represent the microcosmos, we would have to go with the tardigrade. They’re weird, adorable, and hardy, – a combination of traits that has made them many people’s first entry point into the...

You may not want to think about it this way, but your mouth is really just one giant, wet cave for microbes. From the perspective of bacteria, your mouth is not a tool. It is a home. It is a place that provides shelter and food, but it...

Blood is a useful substance, not just for our life, but for our way of thinking. It signifies life, but also accompanies death. It unites those who share it, but in doing so it divides others. It runs hot, it runs cold. Whatever it is we...

Microbes are not just blobs. They are very well-evolved biological machinery, the product of eons of evolution that have exposed their ancestors and them to different homes and food and threats.

The microcosmos is not always a graceful space. Sometimes an organism just needs to get around the way it gets around, even if that means looking like a swimming elephant head with a truncated snout at one end and a rat tail at the other.

Do microbes ever feel fear? Or concern? Or trepidation? While they can’t exactly tell us, they probably don’t– at least not in ways that we could understand. But we can tell that they definitely experience stress.

A useful principle in the story of life is that you should never underestimate algae or cyanobacteria. They’ll just always manage to surprise you, and more importantly, to remind you that everything you have comes down, eventually, to them.

As you’re wandering through the aisles of the grocery store, you might find your attention caught on any number of things. Frozen pizza. Cupcakes. Wine. And as delicious as all of those are, we doubt that any of them undergoes as...

The Gastrotrich has long been a personal favorite microbe of several members of the Journey to the Microcosmos crew. But while we were able to see a lot with the microscopes we had at the time, James—our master of microscopes—has made...

This might not look like much. But every day, tiny little things like this are raining down on our planet. Each one is small, about a millimeter across. But over the course of a year, each individual piece that makes its way to Earth’s...

You might wonder why we would care if a demodex has a butthole or not. Well, we care because they live on our face.

Our world today, the one that we have constructed, feels as if it runs on plastic. It is a building block in our bags, our bottles, clothing, toys, the list could go on and on. Plastic has become so prevalent that it’s almost impossible...
