Astronomers build telescopes to search for cosmic radio waves and learn about the universe. Radio telescopes “see” the sky very differently to the point-like stars seen in visible light. They detect black holes, stars and planets being born, dying stars, and more. They detect invisible gas and can reveal areas of space that may be otherwise obscured by cosmic dust. Professor Virginia Kilborn hunts for cosmic phenomena beyond the visual spectrum.

During intrasexual selection, members of the same sex attempt to outcompete rivals for mates. This is typically responsible the evolution of armaments to increase their chances of success such as larger beetle horns and deer antlers, or larger body size. By contrast, intersexual selection results from mate choice, where certain behaviours or characteristics (e.g. mating calls and bright colours) are considered ideal. But human waste can interfere with this process.

We need to ensure the public are well equipped to make their own decisions based on an understanding of risk. We use education to encourage people to eat 3-4 servings of vegetables per day rather than enforcing it, while safety is ensured with legislated mandates like wearing seatbelts or banning indoor smoking. Yet vaccine mandates have been disputed, though you might die much faster from being infected by someone than passively breathing in their smoke at a restaurant.

It had been known for more than hundred years that increases in concentration were likely to warm the planet. So CSIRO commenced work on the modelling of the whole climate system. But in the 1980s it was realised that very few of our Australian colleagues, across a wide range of different disciplines, were either aware of the potential of global warming, or seriously considering, from their own perspectives, whether it was of any importance.

As we followed the evolving research on how COVID-19 spreads, the effectiveness of various prevention measures, and the development of vaccines, the Australian public became used to reading about research findings and seeing graphs and statistics tracking infection rates. This comes on the back of decades of sometimes confusing and misrepresented science regarding climate change. So how do Australians regard science?
