Placebos are treatments that donêt actually do anything. They have no medical effect and no active medicine. It's not a drug that is intended to improve your health. So why do they sometimes work? Well, it turns out your brain is super...

This video provides an explanation of what diffusion is, how it occurs, and how to change the rate of diffusion. The concept of diffusion is demonstrated through the example of a plate of food emitting a smell that travels across a room....

Professor Dave explains the science and theory behind pericyclic reactions (Part Three)

Glycolysis (Part 4 4) Payoff Phase Review

Glycolysis Allostery

This EKG video explains how to use the 1500-method and the 300-method to determine HR from a regular rhythm.

Cardiac Muscle Physiology T Tubules and Calcium-induced Calcium Release

In this video, we discuss the origin of the sciatic nerve from nerve roots L4-S3, its structure and branches, and basic disorders of the sciatic nerve.

NOTE: The "condition" sciatica is very general but is due to compressed roots...

This is what happens when you ignore the warnings on a Lithium (LiPo) Battery.

First I tried Disassembling the battery to learn about it. Then I tried shocking the battery with a tesla coil. Surprisingly that did not work, so I...

This video discusses the significant sources of pollution in our oceans, focusing on the impact of chemical waste and plastic pollution. It highlights the consequences of pollution on marine life, human health, and the environment. The...

Glycogen Biosynthesis

In this video, we explore the basic processes of positive selection and negative selection, which select competent lymphocytes that don't attack our own self-cells.

This video is a follow-up to the video regarding functions of LH and FSH (the gonadotropins). Here, we look at more detail regarding the synthesis of estradiol and the roles of the Theca Cells and Granulosa Cells.

In the previous tutorial we outlined the basics regarding synthetic biology as applied to materials science. We can engineer microorganisms that will produce virtually any compound we want, via a series of reactions that are catalyzed...

The video discusses the topic of investigating the effect of surface area on the rate of chemical reactions. The presenter explains the concept of collision theory and how chemical reactions occur when particles collide with each other....

Cholesterol Structure (Part 2 2)

This is a lecture presentation on rates of reaction experiments. The presenter discusses the concept of the rate of a reaction and how it can be measured. The focus of the experiment is on investigating the relationship between the...

We know that Robin Hood is an accurate and reliable archer, but just how good is he? Is his aim god-like, or is he subject to the errors and imperfections of mortals? This lesson will continue investigating the concept of reliability,...

In this segment, we discuss the failure of modern medicine to keep up with changes in scientific thought on lipids such as cholesterol. We also discuss several modes of regulation on cholesterol levels in the body.

This video is a lecture presentation discussing recycling and life cycle assessments. The speaker explores the impact that consumers and industrial producers have on the environment, particularly through the production and disposal of...

In this video, I use the previously derived Clapeyron equation (previous video [link below]) to derive the Clausius-Clapeyron Equation.

Lipid Biosynthesis Phospholipid Synthesis 1 Inositols & Glycerols

This EKG video explains how to use the 6-second method to determine HR from an irregular rhythm.

In this video, we discuss the mechanisms of growth hormone disorders such as gigantism, dwarfism, and acromegaly.
