The astonishing Dr Joseph Needham - Part 1 of 3
These days everybody knows that the Chinese invented practically everything hundreds of years ago. What people don't realise is that this understanding is so new; in the early 1950s, nobody, not even those in China were aware of this amazing fact. Then Dr Joseph Needham of Cambridge embarked on an exploration of China and the beginning of his massive work Science and Civilisation in China and in 2008 Simon Winchester's book Bomb, Book and Compass reminded the world of this achievement. Today in part 1 we talk to Simon Winchester but also hear once more the programs made in the 1970s with Needham himself.

Murray Darling water forum
In 2008 Catalyst ran a moving special on the rare flooding that reached the outback this year. Flocks of birds numbering over 20,000 sprung up, as if from nowhere. The Catalyst team presented their research and feelings in a forum recorded at the ABC Ultimo Centre on our Open Day in August and this features today on The Science Show.

Steven Chu energy secretary for Obama
Steven Chu, Nobel Prize winner in 1997, director of the Lawrence Berkeley National Laboratory has been chosen as President elect Obama´s energy secretary. He spoke with Robyn Williams in 2007 on implications of the growing climate problem.
Disabling stolen credit cards
A small spark applied to silicon causes oxidation and the release of energy. The silicon oxygen bond is very strong. The conversion of weak bonds to strong bonds releases energy. The release of energy in this reaction can be controlled and used for various applications. One might be deployment of airbags in cars. Another could be the remote rendering of credit cards to be inoperable. Wireless technology could send a small voltage to the chip causing it not to work. Larger applications are in mining or demolition of buildings.
Leap second
Bruce Warrington explains why an extra second will be added to world time at the end of 2008, and how it will be achieved.
Fish at London´s Natural History Museum
Fish curator Oliver Crimmen takes Robyn Williams on a tour of his fish tanks at London´s Natural History Museum and introduces Robyn to some of his specimens.
Regulating genes and neurons in brains
Fruit flies have tiny brains about a quarter of a centimetre in width and can be seen without a microscope. Andrea Brand is looking for stem cells in adult fruit flies´ brains and trying to understand how genes are regulated throughout life. The aim of the work is to learn how to control cells to produce the right neuron at the right place at the right time. One protein, known by the name Prospero, is responsible for regulating stem cells to produce cells which produce neurons. Without the Prospero protein, tumours result.

Boost for biodiesel potential
The search is on to develop materials for biodiesel which don´t use crops best used for food, and which don´t use farmland on which crops for food could be grown. Tallow is the fat produced when animals are processed in abattoirs. The Materials and Energy Group at Flinders University has developed technology to ensure biodiesel blended with tallow remains liquid at usual operating temperatures. This technology can also be applied to jetfuel biofuel which needs to remain liquid at temperatures as low as 50°C.
The question of global warming
In an article in The New York Review of Books, Freeman Dyson says it is obvious global warming is happening. But he questions whether the effects will be harmful. He challenges the belief that carbon dioxide released into the atmosphere remains for 100 years, saying it is absorbed back into earth, oceans, plants or soil in just 10 years. He says more important global problems are forgotten as we concentrate on global warming.
Death questioned
Theo Thanos denies death actually happens. He says scientists pursue the question confident they´ll get funding for their research.
Darwin´s room at Christ´s College Cambridge
John van Wyhe takes us on a tour of Darwin´s student quarters at Christ´s College. He describes college life when Charles Darwin was a student and debunks some of the myths that have arisen around Darwin´s life.
