More
Hosts: Ed Brown, Penny Dumsday, Chris Curtain-Magee 00:01:22 In 450 B.C., the "Father of History", Herodotus, wrote a 23 line account of a type of Egyptian cargo vessel. This was widely thought to be a fabrication, but a discovery in an ancient Egyptian port city indicates the account was truthful. 00:08:03 The earliest undisputed evidence of humans in Australia comes from a rock shelter in northern Australia and dates back to 65,000 years ago. Now investigations at an ancient midden -...

4/2/2019

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:00:32 Some fish can survive the freezing cold waters of Antarctica thanks to a gene that makes anti-freeze. But how do fish in the Arctic, in the Northern hemisphere, also have the same gene? 00:08:33 Some people can smell when people are sick. Could these 'super-smellers' help diagnose Parkinson's Disease early on? 00:21:26 DNA is made of four nucleotides: G, A, T, and C. Now an interdisciplinary team of researchers has doubled that...

Elliott has a new show at the Melbourne International Comedy Festival, Tesla: Death Rays & Elephants! 00:11:00 For a long time it's been believed that having some potted plants around the house will help filter out pollutants and toxins. But now the evidence suggests that houseplants do very little or even nothing at all when it comes to cleaning the air. 00:17:56...

More
Hosts: Ed Brown, Penny Dumsday, Lucas Randall, Dr. Helen Maynard-Casely 00:01:16 NASA's InSight probe begins drilling into the Martian surface - and stops. 00:17:11 Twins are either identical (one egg splits into two copies) or fraternal (two eggs fertilised at the same time). But that's not always the case - as a mother in Queensland found out when she had sesquizygotic twins. 00:25:44 Timothy Ray Brown, who was known as The Berlin Patient, was the first person to be "cured" of HIV....

SoT 325: We Just Like Meerkats

3/16/2019
More
Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:00:57 As the world becomes more and more urbanised, we hear a lot about the dangers to wildlife from humanity's sprawl. But new research finds Australia's koalas may actually be less stressed in cities - provided adequate green spaces are provided. 00:07:43 For the first time ever, a spacecraft built by a private company and designed to carry people has docked with the International Space Station. The success of SpaceX's "Crew Dragon"...

3/4/2019

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:01:18 Hyabusa 2, Japan's latest sample return mission, has briefly landed on the asteroid Ryugu. It's an ambitious mission looking at the building blocks of the solar system. 00:16:14 And what's the point of dragging samples all the way back to Earth, when we can send whole labs to celestial bodies? 00:20:59 Echidnas are cute but spiky Australian native animals, with rather strange mating habits. But they're in high demand on the...

SoT 322: Captain's Log

2/20/2019
More
Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:01:48 When researchers from the Max Planck Institute were looking at the teeth of an 11th or 12th century German woman they found tiny bright blue specks. This was a clue that illuminated the role women may have played in the history of book production. 00:09:19 What if plants could be trained just like pet dogs? Spoiler alert: they can! Sort of. 00:12:12 Also, plants can hear you with their ear-flowers. 00:21:29 For spiders, their webs...

SoT Special: 2018 Bloopers and Outtakes

2/10/2019

2018 was a big year for science. Is saw the launch of the largest privately built reuseable rocket, the discovery a new organ, and understanding of the wombat's cubic poops. And we talked about all these stories and more on Science on Top. But not everything goes to plan, and this year was no exception! We had all sorts of Skype troubles, we forgot things, we were interrupted by dogs and phones… lots went wrong! But instead of losing the hilarious moments of chaos, we’ve saved them all for...

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:01:24 The giant tortoise Lonesome George, the last of his species, was possibly as old as 102 when he died in 2012. Now sequencing of his DNA has revealed a number of genes that could give us clues about human life expectancy and particularly cancer. 00:08:10 Research into epilepsy has accidentally led to some exciting new developments in the treatment of depression and mood disorders. This is a serendipitous line of inquiry that came from...

SoT 319 error

12/14/2018
More
Our latest episode, 319 - Number Five Is Alive, had a pretty major glitch in that Lucas' track wasn't there at all. I realised the mistake shortly after posting it, and thought I had replaced it with the correct version, but obviously it didn't replace the file. I've re-uploaded it and tested it now, it definitely works! So if you had any trouble playing that episode - specifically if it sounds like Lucas is being rude and not talking - then you may have to re-download that file again. Or,...

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:01:10 Wombats - the cute, pudgy marsupials in Australia, have cubic poops. Square, angular blocks of poop. But how and why? We may now have a better understanding. 00:08:25 HD186302 is a star 184 light-years from Earth. And it's so similar to our sun, it could be long lost twin. 00:16:49 A team of researchers have studied the genomes of a group of microbes called Hemimastigotes and found that they are so bizarre, they deserve their very...

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:02:00 There's a stream of stars hurtling through our region of the Milky Way galaxy, and they're bringing with them a "dark matter hurricane". It's probably nothing to worry about, though. 00:12:16 For the first time since 1889, the kilogram has been redefined according to a natural constant, instead of a lump of metal in a vault in Paris. The actual mass, for all intents and purposes, remains the same. 00:23:51 Previous studies of...

But new research finds that infant smiles are a lot more complex than that. 00:07:34 For the first time, astronomers have observed the clumps of gas orbiting the supermassive black hole in the center of our galaxy using four large telescopes linked together. The observations are in extremely high detail and reveal...
