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

00:00:42 106 Million years ago, supervolcanoes in Australia hurled rocks more than 2,250km away. Such eruptions would have been among the biggest ever on Earth.

00:03:47 These volcanoes are part of a previously unknown trail created by a hotspot underneath Australia, which formed new volcanoes as the continent moved over it.

00:10:49 The long-standing view that life first began in "primordial soup" that was struck by lightening may be about to be overturned. The theory that the first living cells were born deep in the ocean in warm, hydrothermal vents is now gaining traction.

00:18:17 The Europa Clipper is NASA's ambitious mission to send a probe to Jupiter's sixth-closest moon, Europa. Europa is one of the best candidates for life in the solar system, but the mission is now facing serious possible budget cuts.

00:00:50 Olympic athletes are using suction cups to suck their skin up into a cup. But is there any science to cupping? (Spoiler: not much, but some. Well, sort of.)

00:10:30 Promising animal trials suggest Chagas disease, leishmaniasis and sleeping sickness could all be treated and possibly even cured, with one relatively safe drug.

00:13:53 An international team of scientists have discovered that the liquid found in the brood sacks of a particular type of cockroach is a highly nutritious source of protein. One day we might be feeding our babies cockroach milk!

00:18:26 Headlice are becoming resistant to the common insecticides we usually use. But a simple, 3,000 year old treatment could be the solution.

00:00:53 Jupiter's moon Io, the fourth largest moon in the solar system, has a volcanic atmosphere that collapses every day.

00:09:07 A survey of fifty houses in North Carolina as found a correlation between household income and biodiversity. The wealthier the household, the greater the variety of insects found inside.

00:13:46 Data from the Dawn spacecraft reveals that Ceres, the largest asteroid in the main asteroid belt, is not the dead lump of rock we thought it would be. In fact, it may have a still warm radioactive interior.

 

This episode may contain traces of newly elected Australian Senator Malcolm Roberts and his thoughts on carbon dioxide.

00:00:49 One of the bigger mysteries about the surface of Mars concerns the formation of some of the gullies. They look very similar to gullies created by flowing water on Earth, only they don't seem to be caused by water at all.

00:10:48 Modern chemotherapy drugs are improving all the time, but they still have really nasty side-effects. But a study published this week shows some promise of being able to deliver the drugs directly into a tumour, thanks to some genetically modified salmonella bacteria.

00:17:01 At first glance, it seems obvious that turtles have evolved their shells as a form of protection. But a new paper published in Current Biology suggests it initially evolved to help turtle ancestors burrow.

00:02:35 It's been a year since New Horizons flew past Pluto, and now all the data is in. We take a look at some of the big things we've leared about Pluto and its moons.

00:19:57 The Centers for Disease Control and Prevention announced last week that the bacteria that causes gonorrhea may be developing resistance to the only two antibiotics left that can cure it.

00:25:12 While all the major planets in the solar system orbit the sun in a fairly tight plane, that orbital plane isn't aligned with the Sun's equator. Which means either the sun has been tilted, or something has influenced the orbits of all the planets. Two independent scientific papers published last week point to the second option - and Planet Nine could be the culprit.

 

This episode contains traces of Donald Trump and Hillary Clinton discussing climate change.
