Hosts: Ed Brown, Lucas Randall, Peter Miller 00:01:13 The bowhead whale sings a different tune to the humpback whale. It's more jazz to the humpback's classical. 00:07:38 The closest star outside our solar system just did a big burp. And it wouldn't be good for any life on its planet. 00:21:57 The hottest chilli in the world was the Carolina Reaper. A competitive eater ate one, then regretted it. This episode contains traces of Will Smith interviewing astronaut Drew Feustel on the...

4/14/2018
More
Hosts: Ed Brown, Dr. Shayne Joseph, Lucas Randall, Jo Benhamu. 00:01:00 New York researchers have detailled the "structure and distribution of an unrecognized interstitium in human tissues". Or as some are calling it, a brand new organ. 00:16:37 New evidence lends credibility to an old theory of how Vikings navigated the seas. They could have used 'sunstones' and polarised light to find the sun in cloudy conditions. 00:24:39 Thanks to gravitational lensing, astronomers using the Hubble...

Hosts: Ed Brown, Penny Dumsday, Lucas Randall 00:01:06 The Draw-A-Scientist test has been a regular investigation of children's ideas about science. The proportion of women being drawn has risen sharply since the test was first done in the 1960s. 00:09:09 70,000 years ago a small red dwarf star hurtling through space came within a light-year of our sun. Scholtz's star is now about 20 light years away but it's likely responsible for the orbits of a lot of comets and asteroids in our solar...

Hosts: Ed Brown, Dr. Shayne Joseph, Penny Dumsday 00:01:04 In April 2015, unusually heavy thunderstorms flooded Chile's Atacama desert, the second driest region in the world. This messed up the plans of researchers there to study life in the Mars-like desert, but it also told them more about how life can survive in long periods of drought. 00:09:27 Two Dutch researchers have looked at more than 100 examples of dice from the last 2,000 years. This huge collection can give us some clues...

SoT Special: 2017 Bloopers and Outtakes

12/30/2017

2017 was a big year for science. Gravitational waves were detected four times, it was the end of Cassini's mission, and lady dragonflies faked their own deaths to avoid sex. 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...

Hosts: Ed Brown, Dr. Shayne Joseph, Penny Dumsday. 00:01:03 Stromatolites - rocky mounds made of bacterial colonies - have been around for at least 3.5 billion years. But the rise of multicellular life wiped them out except for in a few salty marine locations. Now researchers have discovered some in a remote freshwater wetland in Tasmania. 00:06:51 You wouldn't think it would matter if you were injured in the daytime or at night - but it does.
