Did you know we are still discovering completely new pieces of our anatomies? Even in the last decade, we've found multiple new body parts, including some you can see with the naked eye!

Fat cells don't often receive praise in everyday life, but they probably deserve more credit, as they might be healing our wounds.

Microscopes are great for studying tiny things, but they have limits. Luckily, scientists have found a way to make tiny things larger, and it involves a chemical you can find in diapers.

Most of the meteorites that land on this planet are pretty tiny. And enough of them fall to Earth each day that, theoretically, you could find micrometeorite yourself.

Perhaps you’ve punched out a paper doll or folded an origami swan? TED Fellow Manu Prakash and his team have created a microscope made of paper that's just as easy to fold and use. A sparkling demo that shows how this invention could...

Jessi and Squeaks found a branch growing what looked like white hair! So they brought the branch back to the Fort to run some tests and found out that it isn't hair at all... it's ice!

When you picture a single cell, you probably imagine something super tiny that you had to look at through a microscope. But, there are some huge exceptions to this rule. And we really do mean huge.

Meet some of the world’s tiniest animals -- micro-animals, that can live at the bottom of the ocean, on our skin, even in space!

Humans have long known that glass bends light. However, it took us awhile to figure out that stacking lenses in a tube would open up a whole new world to science, finally allowing us a peek at the microscopic.

In this video Paul Andersen explains how electric charge is quantized and how the smallest unit of charge is 1.6x10^-19 C, or the elementary charge. Robert Millikan discovered the elementary charge using the oil drop experiment. ...

You probably have a vague idea of what sperm does, but not all sperm are created equal, and some have even developed unique adaptations to get where they're going.

Humans have long known that glass bends light. However, it took us awhile to figure out that stacking lenses in a tube would open up a whole new world to science, finally allowing us a peek at the microscopic.

Paul Andersen shows you how to find stomata in a dicot and monocot leaf using finger nail polish and transparent tape. A microscope is required to actually see the stomata.

There’s a question to consider that’s pretty daunting: what is life?

And to try to answer that question, three tools stand out as being especially useful: A book, some experiments, and the microscope! In this episode, Hank talks to...

Scientific discovery isn't as simple as one good experiment. The weird and wonderful history of cell theory illuminates the twists and turns that came together to build the foundations of biology.

Paul Andersen takes you on a tour of the cell. He starts by explaining the difference between prokaryotic and eukaryotic cells. He also explains why cells are small but not infinitely small. He also explains how the organelles work...

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?

"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...

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.
