Dr John Bolton, once of the Radiophysics Laboratory in the CSIRO to conduct secret research on radar for the military, also helped pioneer radio astronomy after the Second World War. He was invited to Caltech to show them how to build radio telescopes — but then resigned and returned to Australia to build the legendary Parkes Telescope.

How do you establish a telescope? For Caltech astrophysicist Professor Jonas Zmuidzinas, the answer involves time, money, and incredibly sensitive detectors that can pick up everything from water in the dusty discs around young stars to galaxies in the far reaches of the Universe.

Shortly after the Hubble Space Telescope launched in 1990, astronomers realised its primary mirror, designed to focus minute amounts of light from distant planets, stars and galaxies, had the wrong curve.

A likely successor for Jane Goodall is Professor Cat Hobaiter, who’s based at the University of St Andrews in Scotland. She told the AAAS audience of her finding the 6,000-year-old mummies of baboons in Egypt. But there are no wild baboons there — so where did those dead creatures come from?

Backyard sprinklers have transformed the Aussie urban landscape. But their path to domination of our suburbs was haphazard — and hinged on the inventions of several knockabout tinkerers.

With an estimated 200 million feral rabbits hopping around Australia, are current viral controls working, and do we need another virus to knock off these invasive pests?

Australia was once home to kangaroos that weighed as much as a quarter of a tonne. A new fossil analysis suggests these hefty creatures could hop - but only if they really needed to.

An almost-complete skeleton of an ancient hominin was found in a South African cave in the 1990s. Nearly 30 years later, questions remain about the individual's species.

A quick online search reveals multiple paid services for naming stars as commemorative gifts. You'll be provided with a certificate and a map for finding your star in the sky. But these names are not official and are not used by astronomers — or anyone else, for that matter. So what's going on, and how do stars really get their names? ‌Featuring: Laura Driessen, radio astronomer at the University of Sydney You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).

A faint orange hand stencil on the wall of a cave in Indonesia just became the oldest art known to science. The art, made by splattering ochre over a hand, had been painted over by subsequent generations and was only preserved because moisture combined with the limestone of the cave to form a protective layer on top. The finding strengthens the picture that humans migrated via Borneo, Sulawesi and Papua to reach Australia at least 65,000 years ago.
