Hank explains the science behind the effects of that wackiest of weeds, cannabis sativa - aka marijuana.

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...

Alzheimer's disease is the most common cause of dementia, affecting over 40 million people worldwide. And though it was discovered over a century ago, scientists are still grappling for a cure. Ivan Seah Yu Jun describes how Alzheimer's...

To some they look like bow-legged cowboys. To others, swaggering pirates. Either way, the two-legged molecules known as motor proteins are what get the job of living done in most of your cells.

Hank introduces us to another amazing organism - the "immortal jellyfish," Turritopsis dohrnii - and explains how it can extend its life cycle indefinitely through a process known as transdifferentiation.

You may have to open your mouth pretty wide to take a bite of a burger, but a Hydra can tear open its mouth to devour food larger than itself.

Hank describes how cells regulate their contents and communicate with one another via mechanisms within the cell membrane.

A Quick Question answer that explains the chemistry that makes minty things taste “cool” and spicy things taste “hot”.

It explains the properties and role of hormones, lists the major endocrine glands and their functions and describes the feedback mechanism of hormones.

We already learned a little bit about receptors and the signaling pathways that they initiate, but what are the molecules the travel throughout your body, carrying messages like little carrier pigeons? They are called hormones and...

A deeper look at the workings of neurons and neurotransmitters in the context of how the human nervous system works.
