Science funding is a national investment – not an expense

As a relatively small and young country, by population if not by landmass, Australia has played a noticeable role on the world stage when it comes to science. Contributions to new technologies, from Wi-Fi…

The first vertebrate sexual organs evolved as an extra pair of legs

We humans use the euphemism for sex that “we like to get a leg over” but the first jawed vertebrates – the placoderms – they liked to get a leg in. They were the first back-boned creatures to evolve male…

Has dust clouded the discovery of gravitational waves?

It’s almost three months since a team of scientists announced it had detected polarised light from the afterglow of the Big Bang. But questions are still being asked about whether cosmic dust may have…
