Dr Alice reports on "open source pharma" for malaria, Dr Karl on space nation #3 - China. Dr Alice on Australian Budgerigars and the traffic control of drones. How Diet is the new highway to human development and is your brain tricking you into making bad choices ? 2017 New Year resolution advice from Shirtloads

Self-described ‘professional space history nerd’ Amy Shira Teitel joins Dr Karl to talk about spaceflight before NASA in her book ‘Breaking the Chains of Gravity’. Hear about cutting edge rocket planes like the X-15 (and its surprising link with tractor seats), the team of seamstresses behind the launch of high-altitude balloons to the edge of space, and how paper plates inspired the engineering of early spacecraft. Tune in for extraordinary, intimate stories from a time that is often forgotten in space-age literature.    

Dr Alice has been shark hunting in the Arctic waters (i.e. through scientific papers) and discovered the oldest vertebrate in the world is at least 272 years old. Meanwhile, back on the land, why are two scientists riding a roller coaster holding a bag with an artificial kidney and stones? Dr Karl is considering a ‘fusion’ breakfast after hearing that spicy food may be good for your health. Fruit salad with chilli anyone? And why does the Zebra finch sing a different song to its eggs just before they hatch?

Marine biologist, diver and author Dr Helen Scales takes Dr Karl deep beneath the waves to share her passion for life in the ocean. Helen talks about her new book ‘Spirals in Time’ on the secret life of shells. Hear about ‘clacking’ oysters, the legend of the Golden Fleece (sea silk) and a creature resembling a pinecone crossbred with a slug. There’s mathematics in the spirals of shells, slave trading in the history of the cowrie shell and just imagine a Harry Potter golden snitch of the sea… it’s real and has an incredibly important role to play in ocean life.

Dr Alice is back in the house for science chat and she’s got popcorn for Dr Karl! But wait, why? They are talking movies and the science behind knowing what’s going on in a film by measuring the chemicals released by the audience. Who knew there could be a link between ‘The Hunger Games’, the Amazon rainforest and being able to diagnose medical conditions? Find out what happened in the case of the ‘poisoned pants’ and what’s the best time to exercise to lose weight? They ask the big questions about coffee – good or bad – and, should you really have a hot cup of tea to cool you down?

Clare Collins is a Professor in Nutrition and Dietetics at the University of Newcastle. She joins Dr Karl for a colourful conversation about your toilet bowl and what it can tell you about your health. Don’t be shy, listen up and discover what weird colours you should not see, and what they could mean. Got green poo? There’s an explanation. How about ‘cappuccino’ wee or purple pee? You’ll be surprised. Find out when to see your GP and what to show and tell. Perhaps you’ll take away Dr Karl’s new mantra: ‘while the eyes are the window to your soul, the toilet bowl is a window to your health.

Dr Karl and Dr Alice put their heads together to discuss the latest research into well… all sorts of stuff! What do hairy leaves have to do with burning plants? Is Dr Karl’s fruit and veggie classification (serve it with ice-cream it’s a fruit, with gravy it’s a vegetable) scientifically accurate? And what exactly do killer kangaroos have to do with being unable to sleep in an unfamiliar bed? Listen up as the Doctors tackle these questions and more. And, if you talk to dogs (like Dr Alice does) there’s an experiment you might just want to try.

Maritime history’s greatest scientific breakthrough was working out longitude, the distance (measured in degrees, minutes, and seconds) of how far a point is, either East or West, of the Prime (Greenwich) Meridian. Dr Karl unravels this discovery with Kevin Sumption and James Hunter from the Australian National Maritime Museum in Sydney, as they talk about the history of navigation and their 2016 exhibition, Ships, Clocks and Stars: The Quest for Longitude. Hear about extraordinary nautical instruments, different methodologies for calculating longitude, and the impact of these inventions and explorations on the world today.

Over 200 million people are infected with malaria every year. Dr Alice Williamson, research chemist, lecturer and science communicator at the University of Sydney talks to Dr Karl about her work with Open Source Malaria. This is a worldwide drug discovery project that shares all data and results (no patents please!) in an incredible collaborative effort to tackle the disease. Hear about the problems encountered, Alice’s work in the lab, the thrill of working together with high school and undergraduate students, and the problem researchers are hoping to have that will point towards a possible cure.

Part Two reveals what happened when one, and then two (!!) of the Kepler Spacecraft reaction wheels went to lunch, how the news almost drove Dr Karl to whiskey, and how the engineers found a brilliant solution and continued on with Kepler Mission 2. A jaw-dropping discussion about the discoveries made, including potentially habitable earth-sized planets, the inconstancy of stars, and the probability of finding evidence of life beyond planet Earth.

Dr Karl looks to the stars to kick off his new podcast with NASA Ames research astrophysicist Dr Natalie Batalha, the Kepler Mission Scientist. From 2009 to 2013, the Kepler Space telescope looked for exoplanets – planets outside our solar system. It stared unblinkingly at a patch of sky which Dr Batalha had selected hoping to find not just exoplanets, but exoplanets in the Goldilocks zone. Find out what happened, what can go wrong and how Dr Karl’s mind was blown to astronomical proportions.
