Making sense of the Heavens above is extreme science. Add radio telescopes and that becomes multi dimensional. Then apply stresses that destroy 4 wheel vehicles in the desert and you have this week's Shirtloads guest. Dr Karl and Professor Lisa (Harvey-Smith). Radio astronomer and Ultra Marathon Runner who quit formal schooling aged 11. Unique in the science fraternity and she is focused on big Science. In her own words "There are no Bigger questions than the ones being asked by astronomers. Where do we come from? Where are we going? Are we alone?"
This week the team are all in the wild blue yonder. Dr Alice talks about mice pups and space and burying sperm deep under the lunar surface. Dr Karl dreams of carbon free plane travel and passengers making space for the lightest element in the universe. And just about a fully formed Dr Jessica on making the newest blue a physical reality.
What makes white coffee so foamy and delicious. That delightful crunch when you bite into the perfect meringue. Scientifically they're both made of the same stuff - protein.

There is Science behind our recipes and with these tips you will do better. Dr Karl and Prof Collins are here to help.
Things are not always how they seem: Dr Karl explains how to be buff, good looking and scientifically believable in order to con the gullible. Almost Dr Jessica explains how a statistical quirk could look like a collision with another universe. And Dr Alice explains that how that wine you're drinking could taste better in another bottle while listening to your favourite violinist playing a Stradivarius that may or may not sound better than an ordinary violin.
This podcast is about Science and a chart. Team leader, Professor Michael Mann, drew it 20 years ago using good science. It's been named "The Hockey Stick Graph" because of the way it shoots up. It had no new information. Instead it drew on an international scientific consensus.
The issue was that it suggested that humans had already changed our climate. The other problem was the clarity with which it expressed those man-made forces. You didn't need to be a scientist read or understand it.
Dr Michael Mann, like Charles Darwin, dared to publish. The self-evident conclusion by many, unleashed powerful interests against both Dr. Mann and the science community. Dr Karl Talks with him about the experience.
Blue Sky Science. This week the lamb in a bag - Dr Alice on the research that may help save premature babies. Almost Dr Jessica with a cat in a box wanted dead and/or alive. And Dr Karl on the viruses that eats bacteria - maybe there is a future for humans despite antibiotic superbugs.
We are what we eat. Organic, low fat, pesticide-free, High Fibre ; Consumers are charged extra for foods with health benefits like these. But when food is packaged, how do you know what is really inside ? Welcome to the world of Food Fraud. This Shirtloads podcast stars two British Scientists who have written all it in "Sorting the Beef from the Bull". Bio-Geo-Chemist Richard Evershead and Biologist Nicola Temple. Dr Karl talking with the "Mulder and Sculley" of the food fraud forensic world.
Natural Nukes - Dr Karl explains how the earth created a nuclear reactor billions of years before we figured out how. Extreme gravity, relativistic rotation speeds and could-have-been alien lighthouses - almost Dr Jessica explains the strange science of the Pulsar. Plus Dr Alice on things that shouldn't go boom - the Lithium-ion batteries that power all our devices.
From the age of six, Xiuhtezcatl has been out to improve our world. He worked locally to get pesticides out of parks, coal ash contained, and fracking moratoriums. He has addressed the General Assembly at the United Nations in New York. He is currently a plaintiff in a youth-led lawsuit against the US federal government for their failure to protect the atmosphere for future generations.
On a brief visit to Australia he talks with Dr. Karl on how to achieve meaningful change as a youth activist.
Dr Alice is talking about Ayahusca a South American hallucinogen that may help depression and other mental disorders, nearly Doctor Jessica exploring number stations and the secret messages that haven't stopped despite the end of the Cold War and Dr Karl on whether the silk handkerchief in your top pocket will stop bullets.
Imagine cooling down 2,300 km of Barrier Reef along the Australian coast using renewable energy. Mind-blowing, right? Dr Brian Von Herzen has such a plan. It's part of a bigger picture that he calls Marine Permaculture - using nature to restore habitat in the oceans. It is a project he has been working towards for over a decade including demonstrations off Hawaii. Dr Karl discussed Dr Brian's vision in Queensland earlier this year. The audio quality varies as it was recorded on location.
Dinosaur Love - What drove them to sex ? Dr. Alice reports that there may be hints in a distant relative. Test Tube Meat ? The cost of manufactured protein will come down says Almost Dr. Jessica. Plus Dr. Karl on Animal Families. They can have kids from different fathers in the same litter. They're not twins. What are they and Why?
Imagine laying a sheet of smart film on a masterpiece like "Starry Starry Night". Without contaminating the surface, you can lift off chemical signatures. Discover what paint Van Gogh used, what drugs he might have been taking and even if he was suffering from a recognisable disease. Dr Alice has the story plus Dr Karl on the growing rubbish dump above our heads and (almost) Dr Jessica on those one-off intergalactic tweets called FRBs - what are they ?
Bacteria are more like submarines than fish. They have propellors and motors. This is one of the extraordinary discoveries that Sydney researcher Dr Matt Baker has been part of. In fact he has gone deeper and is looking inside the different motors bacteria species have. What powers these micro machines ? How they are made ? His stories of life at a micron level are almost beyond belief.
What discovery deserves to be the biggest of the 2016? We say Gravitational Waves and the LIGO team. Einstein said they were theoretically possible a hundred years ago and this story is so big it'll is worth two podcasts. Welcome once again Professor Geraint Lewis from the School of Physics at Sydney University.
LIGO - Laser Interferometer Gravitational Wave Observatory was the detector.
It has found the most elusive of all cosmic vibrations.
One hundred years ago Einstein said they were possible - so mind-bending he changed his opinion twice. A mathematician in the WWI trenches confirmed their theoretical existence and then ... Well this story is so big it'll take two podcasts.
Welcome to our Shirtloads "Gravitational Wave Special Part One" and the Associate Head for Research at the School of Physics, Sydney University, Professor Geraint Lewis. Dark energy, gravitational lensing, galactic cannibalism - our Shirtloads of Science" guest eats them for breakfast.
Searching for other habitable planets, looking for medicines inside deadly poisons and pushing poverty (and wealth) to the limit. A Shirtloads Planet Earth 2017 health check.
Cholesterol is a waxy, fat-like substance that your body needs. When you have too much in your blood, it can build up on your artery walls.

salty Geysers blow (just like earth's underwater Hydrothermic jets) and the prospects for life in our own Solar System are tantalisingly close. Dr Linda Spilker has been with NASA's Jet propulsion Lab since 1977. Her work spans Voyager missions and the current Cassini mission. With 40 years of exploration experience, enjoy our extended edition of Shirtloads. Also find out why you should put September 15th in your diary and how Australia may play a vital role in decoding Saturn's rings. (Warning: Contains Physics, Chemistry and traces of Biology).
Planets are popping up everywhere but what about that new Continent on Earth - Why has it taken us so long to find it ? Which part of the human brain is revealing a relationship with Autism .... and why did we have to ban a certain type of soap ? Surely something as simple as soap can't be that bad ?
