Beagle voyage retraced
It was the Beagle which transported Charles Darwin around the world on his 5-year voyage allowing him to see the enormous variation of life forms which led to his theory of evolution by natural selection.

Jonathan Nally describes the astronomical projects searching for planets. So far, over 400 have been found. Are they just lumps of rock or clouds of gas, or do some support life?
Superstition
Why do we have superstitious beliefs? Some people would not accept organs which could save their life, if they knew they came from a murderer. Why not?! Our brains can play tricks on us and let us accept ideas which have no basis in fact. Bruce Hood explo ...

50 years ago the population of the world was less than 3 billion. Now it´s more than double that number. The projection is 9 billion by 2050. Climate change provides a challenge in providing food for the entire world´s people. The current rate of extinctions is 1,000 times faster than what has occurred in the past. Biodiversity is being destroyed. Martin Rees says we´re in denial about some risks. Top of the list is climate change. Science, says Rees is the glo ...

Richard Dawkins - Darwin´s road to the theory of evolution
Was Darwin the most revolutionary scientist ever? More so than Einstein, Newton and others? He destroyed the argument of his predecessors and changed the world view. Richard Dawkins describes a series of thought bridges which led to the theory of evolution, particularly natural selection.

10,000 years ago, the human population plus livestock and pets would have weighted less than 1% of biomass by weight. Today it is 98%. In 10,000 years we have overwhelmed the planet. We have done this because facilitated by our understanding. Daniel Dennett discusses our success as a species, and the evolution of culture and language, which have allowed us to dominate and now threaten the planet.

Marcus de Sautoy says mathematics is a basic tool and underlies all the sciences. He predicts mathematics will help unravel some of the complexities with the brain. He says understanding the brain and consciousness is one of the ultimate frontiers in science. His role involves explaining the scientific process to the public, including the understanding of probabilities associated with scientific ideas.

A possible future Mars habitat has been constructed in the desert in Utah. It contains rooms and workshops, as well as an airlock with simulation spacesuits. James Waldie designs spacesuits. Current suits are big body shaped balloons filled with gas from the Earth´s atmosphere. The new approach is to use a skinsuit. Pressurisation is attained by way of physical compression. It´s like thermal underwear. This kind of suit may be used on missions to Mars. But what happens ...

Australia, like many countries, has vast resources of coal, but what can we do with it if we don´t burn it?
Why burn coal?
Could our vast supplies of Australian coal be used other than for running power stations? How about a chemical or plastics industry, or as a fertiliser on the land? The Science Show will review the options and ask for your input on the possibilities; the Prime Minister´s prizes for science announced this week.

Coastal erosion is a significant problem in Australia, as with many other nations, and it's set to get worse. Reinhard Flick is studying the problem at the Scripps Institution of Oceanography in California. But he's also an expert on king tides. He says they can be predicted well into the future, which is pretty useful to know if you live on the coast.

Scientists have being trying to find life on Mars for years. First they found water. Another glimpse of hope came when methane was detected, which scientists suggest could be produced by living microbes. Lewis Dartnell is studying the cosmic rays that beat down on Mars, to determine how far into the Martian surfaces scientists may have to dig to find life.

A quantum algorithm has been encoded on a chip for the first time. The approach is known as waveguide on chip. It was first proposed in 2001. Single photons of light are controlled and store information. Compared to an electron spin or a neutron spin, a photon doesn´t react with the environment and thus has very low noise. When used in computing, it increases the speed and power of the computer many times. The challenge has been in preserving the infor ...
