Our appetite for the earth's resources and consumer goods has led to increased levels of carbon dioxide entering our atmosphere, trapping more heat from the sun and leading to global warming of the atmosphere.

Getting outdoors is one of the great pleasures in life. But our expeditions into natural environments can also cause real horror stories to unfold. Discarded rubbish causes the waterways to become clogged, a campfire can leave a nasty visual scar that can last for years. How can we avoid causing these problems? This program examines ways to minimise our impact when enjoying the outdoors.

An introduction to stem cells while assuming no prior knowledge, and covers the following topics: what stem cells are, the difference between embryonic and adult stem cells, IVF as a key source of embryonic stem cells, therapeutic cloning (somatic cell nuclear transfer), the difference between therapeutic and reproductive cloning, potential medical applications of stem cell research and a brief

This program tackles one of the most contentious areas of contemporary science: embryonic stem cell research. Different viewpoints are presented, and speakers include: Professor Alan Trounson, prominent stem cell scientist; Father Norman Ford, an ethics commentator; Patients with life-threatening medical conditions.

Any ecosystem needs energy to sustain it, and the organisms within it. This energy comes in massive quantities from the Sun, although only a tiny fraction of the solar energy hitting the Earth goes towards sustaining life. The flow of energy through an ecosystem is complex, and vital to sustaining all life within it.

What exactly are greenhouse gases? Are they really causing climate change? Global warming has suddenly become the hottest environmental issue, and this program clearly explains the science of the greenhouse effect and the evidence that we are causing climate change.

This program begins with an explanation of nanotechnology, and then demonstrates micrometers and nanometers. Viewers will also examine the special properties of nanoparticles, the gecko effect, carbon nanotubes, surface energy; hydrophilic and hydrophobic surfaces as well as the lotus effect.

This awe-inspiring video shows of the process of human reproduction from conception to birth. It explains how mitosis and meiosis create genetic variation, how the ovum travels from the ovary to the uterus, how sperm pass the cervix, how one sperm achieves fertilization with the ovum, how the zygote begins cell differentiation, and how the embryo grows into a fetus ready for birth.

What can we learn from other cultures about food and nutrition? Some countries share our love for food yet manage to avoid our epidemic of obesity. How do they do it? By studying how other cultures eat, we can gain some useful (and tasty) ideas to adapt to our own needs.

This program challenges all eaters to make decisions about food. Should people eat lots of meat? Just a little? None at all? Are vegetarians on to something or just a fringe group afraid to eat a creature that looks cute? Is meat a key part of a healthy diet or does it contribute to cancer and heart disease? It’s easy to find extreme views on this subject, but what are the real issues?
