When electrons in your retina absorb photons of light they don't emit light, they cause a molecule to change shape - and that lets you see colour!
Cells are like chemical factories. Discover the different ways cells get energy to carry out their daily operations. Learn about the different types of metabolic processes inside cells, such as those that break down molecules to release energy and those that assemble building blocks to make more complex components.
Good question! Find out whether this is possible by watching as biologist at MIT, Dr Sera Thornton explains. What is a genome? And why do genomes need to be decoded? If the rhino genome was successfully decoded and the part that described the rhino horn was isolated, what would the process be for creating a unicorn?

This Connected Learning Experience (CLE) students explore the digestive system in higher animals. In this investigation, the specialised structures and functions of cells in the tongue are explored to determine how this organ helps animals survive.
Claims regarding the taste map of the tongue, published in 1901, are evaluated ...
Take a look at cells, and some of their components, starting from the very beginning of life on Earth. Speculate on the origin of the molecules of life and investigate how they combine to create the structure and function of cells.
Fiery red, cool blue and sunny yellow are phrases used to describe feelings associated with colours. But what actually is colour? Why is it there and what helps us to see it? Follow Chloe Sheridan as she unravels the complexity of seeing colour by delving into its physics and biology. She entered this video in the 2013 ...
A virus is a pathogen that replicates itself inside the living cells of an organism. Influenza, more commonly known as the flu, is an example of a viral illness. Find out what other illnesses have their roots in a virus and how we are combating these viral infections.
Explore genetics, the patterns of inheritance and disease-causing mutations. Find out about Gregor Mendel's historic pea-plant breeding experiments showing that traits are inherited in particular patterns. See how Australian scientists discovered the gene mutation responsible for a type of epilepsy.
Discover that all life is divided into two cell types. Learn about the difference between simpler prokaryotes, such as bacteria, and more complex eukaryotes, the group to which humans and multicellular organisms belong. See the amazing microscopic world teeming within a drop of pond water.
A cell's own genetic material provides the instructions for how it works, but what if we could design our own set of instructions? Synthetic biology combines biology and engineering in the design of new systems and functions for cells. Watch this animated clip for an explanation of this new, innovative technology. See examples ...
Cancer is a major disease in Australia and there are many different types, including leukaemia, and breast and skin cancers. View this clip to discover more about how cancer forms, why it occurs, and what cancer research is being done.

The use of embryonic stem cells for medical research is a hotly debated ethical issue, with much of the discussion focusing on when human life begins. Listen to the views both of scientists and of some people from several faith traditions. In a major stem-cell breakthrough, scientists have discovered a new type of stem ...
An allergic reaction occurs when the human immune system makes a mistake and responds to harmless things such as pollen. Watch this clip to learn about the role that antibodies, immune cells, receptors and chemicals such as histamine play in triggering an allergic reaction.
