Sponges might not look like particularly complex animals, but they've had billions of years to evolve their own special systems. And one of those systems might involve sending messages through their body in the form of light.

What on earth is a xenophyophore? It's a single-celled organism that unlike what you might think is NOT microscopically small. In fact, these ocean dwellers are a little heftier than that! Learn all about them in this new episode of...

Is it possible for there to be a dog that is made of one very determined cell?

The elephant is a creature of epic proportions -- and yet, it owes its enormity to more than 1,000 trillion microscopic cells. And on the epically small end of things, there are likely millions of unicellular species, yet there are very...

The simplest organisms can still accomplish wonders.

Mathematician Steven Strogatz shows how flocks of creatures (like birds, fireflies and fish) manage to synchronize and act as a unit -- when no one's giving orders. The powerful tendency extends into the realm of objects, too.

I took a trip to Washington D.C. to check out some of our nation's most famous monuments. Where do they come from? From the depths of the Earth to the distant reaches of the cosmos, you'll never look at history the same way again

You may think of single-celled organisms as being microscopically small, but these ocean dwellers are a little heftier than that.

How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer's "strength" -- and also its weakness.

From something as miniscule as a cell to the biosphere we all call home, living things fit together in numerous interesting ways. Bobbi Seleski catalogs biology from our body and beyond, tracking how unicellular organisms, tissues,...

Science is about more than just finding immutable laws of nature. It’s about having the imagination to try things and ask questions that might not necessarily lead anywhere, but that just… feel right.

These particular little green organisms show up in the background of other organism’s lives, providing pops of color among other debris. What you are looking at is not a single organism, but rather a gathering of them. Those green bits...

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...

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?

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?

In the middle of the 19th century, a scientist stared into the microscope and found, staring back at him, a vampire.

If you have been following Journey to the Microcosmos for some time, this might sound like a familiar story. Consider this a proper slasher movie sequel.

In May 2013, a shipment of around 1.5 tons of seemingly normal cheese was refused entry into the United States. And while looks wise there was nothing suspicious, according to the Food and Drug Administration, this shipment of cheese...

James, our master of microscopes, seems like a tough person to get a gift for. What do you get the person who has the entirety of the microcosmos available to him with just a glimpse through a lens?<br/>

One thing we’ve heard from many of you is that this show is your sleep show, that soothing bit of media you put on when you need to slow down your brain and drift off. We take that as a huge compliment. It’s nice to know we can be a...

"Correction: 03:09 Leafy liverworts are estimated to make up the majority of the diversity of liverwort species."

"Correction: 05:08 Not all thalloid liverworts have gemma cups, and there are leafy liverworts that use gemmae for...

Do you know what’s in your water? Do you know what’s buried deep in those depths?

When James, our master of microscopes, was looking through samples he’d received from Spain, he didn’t expect to see this—a creature straight out of a horror movie, with dark reddish brown eyes and tentacles streaming out of its...
