S7E6 - Avoid 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.

S7E7 - This Neon World Is Inside Your Fruit
Usually we’re looking into pond water or whatever other fascinating bit of nature that James, our master of microscopes, usually looks at. But right now, our sights are coming to us directly from the kitchen and from a different master of microscopes.

S7E8 - Up Close With The World's Deadliest Animal
Under the microscope, mosquitos undergo a metamorphosis sculpted in gold. The buzzing body takes on a life of its own, its usual role as menace lying far beyond the margins of the screen.

S7E9 - Falling In Love With Microscopy
This video is all about James, who many of you know as our master of microscopes. He is the scientist, and the artist, behind just about everything we are able to see in our collective journey through the microcosmos.

S7E10 - The 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?

S7E11 - Why 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?

S7E12 - The Electric Relationship Between Plants And Bees

S7E1 - 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.

S7E2 - When 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.

S7E3 - The 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?

S7E4 - Why 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.

S7E5 - We 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.

S7E14 - Liverworts 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.

S7E15 - Bacteria 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.”

S7E16 - Is It Possible To Photosynthesize In The Dark?

S7E18 - Blood-Sucking Escape Artists
Of all the animals that we’ve examined in the microcosmos, leeches are probably one of the few that can be used as a verb, to leech off someone—to take and take from them, like a worm consuming someone’s blood.

S7E28 - We 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.

S7E33 - This 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.

S7E38 - This 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?

July 9, 2024, midnight
S7E46 - What These Microbes Teach Us About Free Will
We’re focusing today on a Journey to the Microcosmos favorite: the ciliates, the single-celled eukaryotes covered in hair-like structures called cilia. We want to be more self-centered and explore what ciliates have taught us about ourselves.
