Science On Top
The Australian Podcast putting Science on Top of the agenda

Hosts: Ed Brown, Penny Dumsday, Lucas Randall

00:01:23 Danuvius guggenmosi was a great ape that lived 11.6 million years ago in southern Germany and it has just been formally described in the journal Nature. But the really interesting thing about this discovery is what it could suggest about bipedalism - our ancestors were walking upright much earlier than previously thought.
00:10:19 Spaceflight is a dangerous endeavour. Astronauts risk muscle atrophy, bone weakness, cardiovascular issues, eyesight disorders, and a host of other ailments. But now, researchers have found another serious health risk: stagnant or backwards blood flow in the internal jugular vein.
00:19:16 Some people who don't like vegetables may have a genetic reason to avoid their greens. (But some people are also just fussy!)
00:25:52 Researchers in Sweden have created a molecule that they claim can trap solar energy and store it for decades. But there isn't a lot of information available about it.
This episode contains traces of an ABC News report about a real life "Breaking Bad" situation.

00:00:35 Researchers at the University of Richmond taught a group of 17 rats how to drive tiny little plastic cars. The rats found driving to be relaxing!
00:11:28 Why do we like music? It's a question that neuroscientists have wondered about for decades. A paper in the Journal of Neuroscience suggests it's related to learning.
00:18:37 Cows can not only recognise other cows, but they form friendships and bonds that don't align with the social hierarchy of the herd.
00:26:28 Ornithologists in the Amazon have recorded the world’s loudest bird. It's mating call can reach 125 decibels - louder than front row at a rock concert.

00:00:32 A zebra's stripes seem to reduce the number of flies that they attract, so what would happen if you painted a cow like a zebra? Japanese researchers did exactly that, and found a similar result.
00:08:10 An intriguing new hypothesis for Planet Nine is not a planet at all. Two astrophysicists have speculated it might actually be a very small black hole in our galaxy.
00:25:43 By analysing cut marks on bones left by humans between 200,000 and 400,000 years ago, archaeologists have determined that the bones were kept for later consumption. Weeks after the flesh of the animal was eaten, it's believed, the marrow in the bones was still nutritious.


This episode contains traces of Boeing Communications' Jessica Landa and NASA Public Affairs' Dan Huot immediately after the successful Pad Abort Test of Boeing's Starliner Spacecraft.
