The Complicated Sex Lives of Hydra
If we were to write a fable to get this moral across, it would have to star the freshwater cnidarian called the hydra. Because in the hydra, the question of butts connects to the ambiguities of immortality, which in turn relates to the befuddling matter of sexual reproduction.
Read MoreWhen Is A Fungus Not A Fungus?
Oomycetes are one of the more unusual-looking microbes we’ve seen in the microcosmos. It looks more like a coral reef painted by an artist inspired by Gustav Klimt and a pile of trash. And if you saw that painting hanging in the museum, you might pass it by without thinking much of its subject.
Read MoreThe Cryptic Origins of Yogurt
The microcosmos is home to many unusual partnerships. Life is, after all, just relationships, each of which build upon one another like strokes of paint in an epic tableau of ecology, epidemics, and yogurt?
Read MoreWhy Beggiatoa Are Stuffed Full Of Sulfur
There’s a few things that give Beggiatoa away. The first is the simple serpentine shape of their bodies, and the second are those little dots inside of them. They look like bubbles, but they’re actually sulfur granules.
Read MoreWe Don't Know Why Moth Wings Glow
A little while ago, James found himself with a bit of a problem. He was keeping some wheat grains at home to use as food for the microbes that he cultures and films for our enjoyment. But before he could feed the grains to his microbes, they became infested with the larvae.. of moths.
Read MoreAvoid These Tiny Bits of Killer Fluff (If You Can)
When you hear the phrase “brain-eating amoebas,” is there a particular image that comes to mind? Whatever you envision, it's probably not what the notorious brain-eating amoeba that strikes fear in our hearts actually looks like.

Read MoreThe Tiny Worlds Inside of Puddles
When was the last time you saw a puddle? Was it recent—perhaps some time in the past week, fresh from a downpour? Or has it been a long time since you’ve seen rain, and so an even longer time since your path has crossed a puddle?
Read MoreWhy Are Some Birds Blue?
One of the spectacular details of animals in our world is just how varied their colors can be. When you look at birds, for example, you’ll see everything from mundane grays to iridescent blues. So why don’t we shine with the same iridescence of birds?
Read MoreThe Electric Relationship Between Plants And Bees
When you think of bees, you probably don’t think of single-celled eukaryotes. What could an insect have in common with, say, a ciliate?
Read MoreFloating Cities of Scum
When you think of bees, you probably don’t think of single-celled eukaryotes. What could an insect have in common with, say, a ciliate?
Read MoreLiverworts Use The Rain To Make Their Clones
An ambiguously long time ago, there was this theory of medicine. An idea that if you came across a plant that looked like a body part, that meant it was meant to treat ailments that targeted said part. And this put a lot of pressure on liverwort, simply because it resembled the liver.
Read MoreBacteria That Survive In Gelatinous Colonies
In the 1820s, a man named Dr. R. Brandes walked through a meadow on a quest to try and answer a centuries-old question about a mysterious gelatinous substance on the ground known as “star jelly.”
Read MoreIs It Possible To Photosynthesize In The Dark?
Our master of microscopes is always looking for rare ciliates that live in areas low in oxygen. But when he puts those samples under a growth light, his tubes quickly turn the color of the green sulfur bacteria that thrive in those anaerobic conditions.

Why Picocyanobacteria Might Just Outlast All Of Us
In the northeast Atlantic Ocean, plankton populations aren’t looking like they used to. And at the center of it all are tiny, photosynthetic bacteria called picocyanobacteria who may just outlast us all.
Read MoreWe Built A Tardigrade Trap, And It Worked
We don’t know if there are many rites of passage institutionalized among amateur microscopists. But we have to imagine that, as people find themselves navigating the microcosmos for the first time, they’re often on the lookout for tardigrades.
Read MoreThe Microbial Universe That Makes Kombucha
When you think of kombucha, you might think of a nice, refreshing, healthy drink, one that’s exceptionall good for your microbiome. What we here at Journey to the Microcosmos think of is a terrarium…a place where a whole ecosystem exists, trapped in glass.

After an absence of almost 90 years, we’ve found a rare ciliate last written about about in 1933.
Read MoreWhat Makes A Microbe Rare?
In the microcosmos—where the organisms vastly outnumber us, where what we find in a single pool of water can change from day to day—it makes us as what it mean for a microbe to be rare?
Read MoreThese Tiny Crustaceans Hate Change
One of the fascinating aspects of microscopy is the way you can look so deeply into something that it becomes unrecognizable. What could look like a stained glass window could actually turn out to be... a hopping shrimp?
Read MoreThis special diatom is having a very bad day
It’s hard to count how many times we’ve encountered diatoms on Journey to the Microcosmos. However, we've always talked about the more colorful variety of diatom, and not the ones that are colorless.
Read MoreWe Fed Our Microbes Blood So You Don't Have To

Today James, our master of microscopes, is using a microscopy slide as a cutting board, chopping away at the slide to end up with a bunch of individual stentors.
Read MoreThis Amoeba Made Armor From Its Dead Enemies
This amoeba has a shell around it, which seems like a pretty good idea. The world at large is full of predators, and shells seem like a straightforward strategy to ward those predators off. But what if this amoeba’s shell wasn’t just a form of protection? What if it was actually dangerous?
