The Australian Podcast putting Science on Top of the agenda

00:00:26 A seemingly successful treatment of a nasty genetic disease would not have been possible without zebrafish.
00:10:52 It may seem counterintuitive, but a strain of virus linked to the common cold has been used to treat patients with a type of bladder cancer.
00:20:44 Fast Radio Bursts - the strong blasts of radio waves from distant galaxies - have mystified astronomers since they were first detected in 2007. But now for the first time, an FRB has been traced back to its host galaxy, 3.6 billion light years away!
00:33:39 Psychologists have conducted a large survey of nearly 2,000 volunteers to determine which animals and insects people are most afraid of, and most disgusted by. Perhaps unsurprisingly, it didn't go well for spiders.

This episode contains traces of astronaut Buzz Aldrin talking about the meaning of the Apollo 11 moon landing.

00:00:25 Dogs have evolved - mostly through artificial selection - to be our best friends. And a part of that evolution, according to a study published in the journal Proceedings of the National Academy of Sciences, meant developing special muscles to help them give us those "puppy dog eyes". You can test your own dogs "dognition" at!
00:15:27 It's widely believed that at the centre of every large galaxy there's at least one supermassive black hole - a black hole that's millions or even billions of times more massive than our Sun. But earlier this year a group of astronomers announced a discovery that means the accepted theory of how a they're formed is wrong. But there are some plausible new theories that could explain it.
00:25:08 Media reports that mobile phone use could be causing teenagers to develop horns on the back of their heads were alarming and widespread. But perhaps unsurprisingly, those reports were flawed interpretations of bad science.

This episode contains traces of business journalist and Sunrise breakfast television show presenter David Koch discussing external occipital protuberances with lead author and chiropractor Dr. David Shahar.

00:00:39 Winemaking in France dates back more than 12,000 years. But new research looking at the DNA of ancient grapes has found one particular variety that's remained unchanged for over 900 years.
00:09:13 The largest crater in the solar system, the South Pole-Aitken basin, is on the far side of the moon. And astronomers have found an unexpected very dense mass there, deep below the surface.
00:19:08 Positron Emission Tomography - better known as PET scans - show levels of chemical activity in the body and are useful, for example, for detecting cancer cells. Now new modified PET scanners have been demonstrated that drastically speed the process up and reduced the amount of radiation used.

This episode contains traces of a BBC News report and surprise guest on stage at Glastonbury Festival 2019.
