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.

The cell is the basic unit of life, and our understanding of it has advanced as science, and the tools available to scientists, has advanced. In this episode of Crash Course Biology, we’ll take a look at the difference between...

Scientists want to know why cancer cells sometimes return after chemotherapy has eradicated the tumor. One debated theory is that cancer has its own "stem cells". Three studies published in Nature and Science are in support of this...

Students will learn about the discovery of cells, the development of the cell theory, and the differences between animal cells and plant cells, Animations illustrate the different parts of a cell. Other terminology includes: organelles,...

There's another theory about the Covid-19 pandemic going around, and while it is pretty cool, it's not exactly the solution some are suggesting it might be.

People have struggled to understand some hypotheses scientists had, which are correct but were disclaimed back then. So here’s the 5 scientists and their ideas that nobody believed.

The cell nucleus is crucial to multicellular life, so you think science would have a good idea how it evolved. The truth is, we don't, but Scientists do have some theories, including invading giant viruses!

Could rock music one day replace your insulin injections? Scientists are pioneering music-controlled cells that could provide the perfect dose of insulin for type 1 or type 2 diabetes with just a bit of music. Specifically, Queen's "We...

In the 1860s, scientists believed they were on the verge of uncovering the brain's biggest secret: how the brain's signals travel through the body. They believed these impulses travelled uninterrupted along a massive web of tissue. But...

How low in complexity can you go and still have free will. Does a bacteria have free will? Do single cells have it? What do we know about agency in living systems? I collaborated with physicist and author Philip...

In this video, the teacher explains the concept of the fossil record and its importance in supporting the theory of evolution. By studying and piecing together millions of fossils, scientists have developed a clear picture of how life...

Science offers a way of discovering and understanding the world around us, driven by questions and tested with evidence. And it’s a twisty-turny team effort— you won’t find many lone geniuses out there, or straight lines from hypothesis...

This never-before-seen neuron was just found in the human brain, and it might hold the secret to what separates us from other animals. We Didn’t Think This Part of the Brain Existed, and It Could Save Your
