The life of galaxies
Galaxies are not static. They are dynamic clusters of stars which are constantly changing. As galaxies grow, they can consume other galaxies. Indeed our own galaxy, The Milky Way is currently eating two smaller galaxies. Geraint Lewis describes the process of galaxy formation and what happens as galaxies collide.
The possibility of life beyond Earth
Is the universe made for it? Is the universe built for life? The origins of life remain a stubborn mystery. So was the formation of life a likely or unlikely event? A fluke or part of the laws of nature? Answering this question helps with the other question about life elsewhere in the universe. Biological determinism states suggest that life forms given the right Earth-like conditions. Paul Davies describes how this might be tested?
Simulating the life and death of galaxies
Darren Croton uses the results of supercomputer simulations to study the universe. Our sun is just one of about 10 billion stars in our galaxy, the Milky Way. At the centre of the Milky Way is a super-massive black hole. Itīs a million times the mass of our sun. This is determined using the basic laws of physics. But some galaxies appear quiet, almost dead. So what kills a galaxy? One suggestion points the finger at super massive black holes.

Music and the cosmos
This week The Science Show presents a special event celebrating the International Year of Astronomy. The University of Sydney gathered its forces from physics and music for this journey around our galaxy and beyond. Hear how violent, chaotic and dangerous the universe is away from the comforts of planet Earth. When stars like our Sun some to the end of their lives, they explode in a catastrophic event known as a super nova. The last one happened in our galaxy 400 years ago. Some galaxies see them almost monthly! Then thereīs the search for planets, and the possibility of extra-terrestrial life. So far more than 300 planets have been discovered although so far thereīs no evidence of life beyond Earth! The evening featured The Sydney Conservatorium Brass Ensemble performing movements from Gustav Holstīs The Planets suite.

Making or influencing a million from science
What do we dream from science? To make a million dollars? Or perhaps to influence a million people... or more! The Science Show this week presents a forum where successful science researchers and entrepreneurs describe how their work has changed the world, how the products that have come from their research have influenced a million people, and quite often, made a million... or more! This forum was presented as part of the Australian Science Festival 2009.

Heaven + Earth - review by Malcolm Walter
Geologist and planetary scientist Malcolm Walter reviews Ian Plimerīs book, Heaven + Earth.
New Zealand houses: draughty and deadly
Houses in New Zealand donīt protect their occupants from the temperate climate of high rainfall and strong westerly winds. The housesī designs are based on those from other parts of the world. And now adverse health effects have been measured. More people die in winter than summer, a higher proportion than in other countries. Even Siberiaīs houses offer more protection from winter conditions.
Heat shield protects houses from fire
Gwion Cain describes his heat shield, designed to protect houses from bush fires. Itīs a silica tent which envelopes a building. It can also be used to protect vehicles.
Nobel laureate Rita Levi-Montalcini celebrates 100th birthday
Lyn Beazley, Chief Scientist of Western Australia, pays tribute to Nobel laureate Rita Levi-Montalcini on her 100th birthday.
Computers model human behaviour
Svetha Venkatesh is using multiple inputs from cameras and sensors to build a bigger picture. An example is an image of a city built from front-facing cameras on buses and other vehicles. This data can be used to detect criminal activity, such as graffiti. Underlying this technology is machine learning, having a computer compare a model of normality with a variation. This has applications in some medical fields such as early intervention technologies for autistic children.
Digital history
British government digital records from just 10 years ago are now unreadable because of changing technologies. The same applies to web pages. Now techniques are being developed to capture web pages in an archive.
