An exploration of the role of the neurotransmitter serotonin in the development of depression. I discuss the role of serotonin in promoting the production of neurotrophic growth factor, the role the growth factor plays in facilitating neurogenesis an...

In this special episode I discuss genetic testing with Kira Dineen from DNA Today. We cover a range of topics including the process and science behind genetic testing, the types of genetic conditions that can be tested for, the difference between gen...

A discussion of earthquakes, covering the elastic rebound theory of earthquake generation, the phenomena of deep and intraplate earthquakes, types of seismic waves, methods of earthquake detection, different ways in which earthquakes cause damage, an...

A discussion of the awesome power of volcanoes, including an overview of the different types of volcanoes, types of lava and pyroclastics, mechanisms of volcanic eruptions, a curvey of volcanic landforms, and a review of some major historical eruptio...

Concluding the two-part series on the circulatory and respiratory systems, I discuss the biochemical mechanisms by which red blood cells and hemoglobin molecules deliver oxygen to the tissues and carbon dioxide to the lungs, and the mechanisms which ...

An overview of the basic concepts of linear momentum, angular momentum, work and energy. Includes a discussion of the conservation of momentum, why the concept is needed, and some applications of the concept to collisions and rotating objects. The na...

A discussion of the importance of the profit motive and freedom of competition in the efficient operation of a market economy. Includes an overview of the uniformity of profit principle, and an examination of how competition serves as both an opportu...

An overview of how atoms bond together to form different chemical substances, including a discussion of the tree main types of bonds (covalent, ionic and metallic), and the relationship of these bonding types to the concept of electronegativity. I al...

An introduction to the key principles of quantum mechanics, beginning with an examination of the quantum-mechanical description of the behaviour of electrons around atomic nuclei. This is followed by an overview of some of the other major principles ...

An introduction to basic Newtonian physics, including a discussion of forces, velocity, acceleration, Newton’s three laws of motion, and some common misconceptions about forces. I also discuss circular motion, and conclude with a brief look at the ph...
