Hank profiles this year's Nobel laureates in science, whose achievements have helped us understand questions as small as how our cells transport materials, and as big as why matter exists at all.

Rocks or mineral crystals can often remind us of other things in our daily lives, but coming across some of THESE rocks might be one of the creepiest experiences a rockhound can have!

In this video Paul Andersen gives an overview of the human urinary system. The system consist of the kidneys, ureters, bladder, and urethra. The kidneys excrete waste from the blood in urine. He explains how the nephron is responsible...

In 2017, a truck screeched to a halt. One of its containers slid off, hit a car, and spilled its contents— thousands of kilograms of hagfish. The result of this accident was an absolute mess: the highway was coated in a thick slime that...

Hank and the gang return with SciShow Quiz Show, where Sci Show's resident geniuses compete to win prizes for our subscribers!

Cell membranes are structures of contradictions. These oily films are hundreds of times thinner than a strand of spider silk, yet strong enough to protect the delicate contents of life: the cell's watery cytoplasm, genetic material,...

In this video, we delve into the inner workings of a vital cellular organelle, the golgi apparatus, also know as golgi complex and golgi body. Join us as we unravel the Golgi apparatus's structure, functions, and its pivotal role in...

Cell Material Transport describes the functions of membrane-bound cellular organelles by explaining how each facilitates transport of materials within cells.

A study published in Cell Host & Microbe found that different stomach virus tend to be more contagious when the virus particles cluster together.

When the action potential reaches the axon terminal, this triggers a series of events that result in the release of neurotransmitter to the synaptic cleft. Neurotransmitters bind to the receptors on the postsynaptic membrane causing a...

In this episode, I talk about the concept of facilitation and explain how it results in a stronger signal in the postsynaptic cell.

Lesson on the Insulin Signaling Pathway and its Regulation of the AKT Pathway. The insulin signaling cascade is activated upon binding of insulin to the insulin receptor. Afterwards, downstream targets, including IRS1/2, become...

So far in this CTE Skills Anatomy and Physiology series we've covered the main parts and the main functions of the integumentary system. In part 3 we will be going over the diseases of the skin.

Learn the insulin signaling transduction cascade/pathway in this biochemistry powerpoint-style lecture!



Hey guys! Here is a new video where I teach the insulin signaling pathway in a new powerpoint style lecture format. Please...

Through real world footage and animation students will learn how igneous rocks are formed and where they are located. Viewers will understand the differences between intrusive and extrusive rocks and how various landforms are made. Side...

Prokaryotic cells were simple enough, but eukaryotic cells are much more complex! They have so many more little features and compartments, like the deluxe model of your car. We have to learn about every single one of these organelles and...

Cell Structure and Function Set: 6. This clip examines the structure and function of the golgi apparatus in transporting cell products.
