The Mind's Big Bang - 60 minutes
Between 100,000 and 50,000 years ago, something happened that triggered a creative, technological and social explosion, allowing humans to dominate the planet. What forces may have contributed to the emergence of the modern human mind?

Contains 3 episodes, each about 30 minutes in length. In each episode, a team of scientists that includes biologists, chemists, and physicists are transported to an isolated island where they must work together to solve challenges using mainly indigenous items.

Includes 3 episodes, each about 30 minutes long. In each program a team of scientists that includes physicists, chemists, and biologists and botanists are transported to an isolated island where they must work together to solve challenges using only rudimentary tools and indigenous materials.

Contains 4 programs, each around 30 minutes long. In each program, a team of scientists that includes biologists, chemists, and physicists must work together to solve challenges using only rudimentary tools and indigenous materials.

Despite its wonders, Earth's water cycle does not spread water evenly around the planet. The Ogallala Aquifer’s huge underground reservoir of water gives the relatively dry Central Plains states such as Nebraska a large but limited irrigation source. But the aquifer's water is being used up faster than it is beng replenished.

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.

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.
