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.

00:10:30 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.

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.

00:00:39 A decade ago, the Great Southern Reef stretched for 8,000km off the coast of Western Australia. Now, a long-term study shows how decades of ocean warming combined with a marine heatwave has devastated the kelp forest. We caught up with Dr Scott Bennett from the Spanish National Research Council, one of the primary investigators on the study.
00:20:04 A new study has found that capuchin monkeys in Brazil have been using stones as tools to prepare their cashew feasts for more than 700 years.
00:24:49 Researchers at the Stanford University School of Medicine have made a major discovery that could determine whether a patient has a bacterial infection or a viral infection by through a simple blood test.
00:31:26 The European Space Agency has announced an ambitious plan to catch a derelict satellite in a net, and burn it up in Earth's atmosphere.
Dr. Scott Bennett is a Marie Curie Fellow at the Spanish National Research Council (CSIC), and Research Associate in Marine Ecology at Curtin University.

00:01:29 713 Trillion gallons of water found deep underneath California. But we can't touch it... yet.
00:09:48 A pair of wings found encased in 99 million year old amber suggest that the plumage of modern birds has remained almost unchanged from some of their dinosaur-era ancestors.
00:13:58 Thirty eight rare hazel dormice have been released into the Yorkshire Dales National Park in England in a conservation effort. But the declining dormouse population raises other issues about how changing land use is affecting the wildlife.
00:18:45 A three-year study of a reef in the Florida Keys has shed light on how microbes are crucial to keeping coral reefs healthy Overfishing, pollution and climate change can destabilise the coral's natural defence and disrupt ecological communities.

00:00:55 Fish that spend part of the time on land - such as mudskippers, American eels, and sea scorpions - may have evolved that ability separately more than 30 times!
00:07:08 Tabby's Star, also known as Where's The Flux, has been described as "the most mysterious star in the universe". It's the star with the strange dimming patterns that caused some speculation that it might be an alien megastructure. Well it almost certainly isn't an alien megastructure, but the story behind its discovery and the plans to study it closer are just as cool!
00:18:00 A new study finds links between low-fibre diets and peanut allergies.

00:01:05 For the second time, physicists have detected gravitational waves, proving that gravitational wave detection is a viable new form of astronomy. It also opens the way for theories about space-time having a memory, and possible explanations for dark matter.
00:30:38 A long awaited WHO report says that not only is coffee not carcinogenic, but it may even prevent some cancers. It's not so good news, however, if you like your coffee hot.
00:42:58 NASA's Juno spacecraft is set to enter orbit around Jupiter on July 4th, and NASA has released a Hollywood-style trailer for it.

00:00:52 Michelle Franklin joins us to discuss invasive species control - from giving herpes to carp, to the moth that nearly wiped out the prickly pear.
00:16:57 Scientists have trained archerfish to recognise - and spit at - specific human faces.
00:22:46 A woman in Pennsylvania recently tested positive to an E. coli "superbug" that's resistant to most antibiotics. That's scary enough, but it also points to a worrisome lack of testing and reporting with urinary tract infections.
Michelle Franklin is a wildlife biologist and a founder of the Darwin Skeptics.
Phil Kent is an aquaculture specialist and secretary of the Brisbane Skeptics. Brisbane Skeptics have a Skepticamp coming up. Phil can be found on Facebook, Twitter and at the Brisbane Skeptics' Facebook page.
