What happens when you squeeze a star ? Dr Karl gets inside one with Professor G. Lewis. They travel from the subatomic level up with the latest on Neutron Stars. Trigger Warning - Quarks and Bosons are mentioned . It's part one with more from the Neutrons next time. http://www.physics.usyd.edu.au/~gfl/
To study the stars, look to the ocean. Water ebbs and flows under the influence of gravity. Astronomers see tides in moons, stars and around black holes. Dr Karl talks with two astrophysicists who recently measured a bulging star with earth-like tides.

They're back ! Dr Karl on why carbon dioxide is so insidious in the atmosphere. Dr Alice Motion on the best Instagrams yet of our sun and Dr Jessica Bloom on the rise of bio-robots. The original shirtloads gangsters are in the lab.
American climatologist Michael Mann drew a chart back in 1999 . It's called "The Hockey Stick Graph" because of the way it shoots up. There was no new information in it and it drew on agreed international temperature data. Like Charles Darwin, Dr Mann dared to publish. His "hockey stick" still makes him a target for fossil fuel lobbyists. So what happens when a scientist is taken on by powerful interests ? Dr Karl asks him about the experience....
One star, observed in outback Australia, may hold new clues to dark matter and black holes. It's a milky way neighbour but moving very fast. Prof Geraint Lewis takes Dr Karl on his quest for answers. http://www.physics.usyd.edu.au/~gfl/
The Young Australian of the Year Award recognises 16- to 30-year-old Australians. It rewards their achievements and contributions. Dr Karl meets Corey Tutt, the NSW winner for 2020. Corey has already made an extraordinary difference with his Deadly Science initiative.
The Hubble Space Telescope launched in 1990. It is named after the American astronomer who found our universe was expanding. Ninety years on, with much better kit, Hubble’s ideas still hold. The question is how fast are we inflating? This is the Hubble tension and Prof Geraint Lewis leads Dr Karl through the deep space discussion. http://www.physics.usyd.edu.au/~gfl/
What is the science behind warning pregnant women to stay away from cat faeces ? It involves a parasite (called "Toxo" for short) that migrates between humans and their cats.

We are officially in an interglacial period - between ice ages. Dr Karl talks with Australian Glaciologist Dr Tas van Ommen about the times when Ice sheets were a kilometre thick. What caused them and how long did they last. Understanding our climate history is our best chance for anticipating its earth's future. Recorded in Antarctica
Dr Karl and AI expert Dean Blumenstein from UTS Sydney discuss the application of drones being deployed on Australian beaches. Can deep learning improve on helicopter surveillance ? Could a drone save someone faster than lifeguards ? How safe in are we in the hands of AI ?
Guardian Australia's 2017 bird of the year was the Magpie. They are notorious for swooping and pecking bike riders so why are they so popular ? Dr Karl joins Prof Kaplan in the cradle of bird life. Australia saved the birds and some of the smartest ones are still here. https://www.panmacmillan.com.au/9781760554200/
Dr Nick Fuller investigates the claims behind fasting diets and why today, most of us will end up where we started and feeling Hangry. He and Karl go through a recent study to show how deceptive it can be. It's not willpower that lets us down but something much deeper. There are proven long-term plans - fasting is not one of them.

Marine Biologist Dr. Daniela Ceccarelli has been studying the Great Barrier reef for around 20 years. She lives and works there and has uncovered some of the complex relationships between seaweed, algae, fish and coral. One of her surprising discoveries involves the humble Damsel fish. Dr Karl talks to her on Magnetic Island about her research and containing the damage that agricultural run-off and sea temperatures are having on reefs.
What controls our sex life ? Dr Amee Baird has a tremendous insight into this. As a clinical neuropsychologist, she has studied many people whose sexual behaviour suddenly changed. It remains a taboo subject for many, and so she has written a book about what she has learned. Dr Karl spoke with Dr Amee Baird in Sydney about her book "Sex in the Brain". https://newcastleneuropsych.com.au/dr-amee-baird/...
Dr Bernie probes the Augmented Realities inside Dr Karl's new book. Are the 3D animations impressive ? Do the walking, talking virtual Karls look amazing on her phone ? Is this the new frontier in science publishing ? https://drkarl.com/books/
2019's Australian of the Year Award was most unusual, shared between two extraordinary people - Veterinary Surgeon, Craig Challen and Anaesthetist Richard Harris. They were pivotal in the rescue of a Soccer team trapped in a cave deep in the mountains of Thailand. In this special 50-minute podcast Dr Richard Harris takes Dr Karl through that extraordinary cave rescue during the South-east Asian Monsoon. https://www.penguin.com.au/ books/against-all-odds- 9781760890957...
Dr Alice Gorman is an internationally recognised leader in the emerging field of space archaeology. So how do you create a job like that? It begins with rubbish. Dr Alice takes Dr Karl back to the fundamentals of preservation and how to sort space junk from the keepers. @drspacejunk.
How do you un-boil an egg? A Professor of Chemistry showed what was possible and won an Ig-Nobel Prize. It's all about the structure of proteins and how you fold them.
Firestorms attacked Australia's Capital City in 2003. Four people died. Dr Karl meets Prof Jason Sharples. His analysis has altered the world's understanding of fire.

Rocket propulsion Scientist Dr Rachel Brachman and astro-chemist Dr Michael Malaska join Dr Karl to scope how and where to start looking for signs of life beyond Earth. https://solarsystem.nasa.gov/scientist-for-a-day/home/ https://eyes.nasa.gov/ https://projectpanoptes.org/ @WATSONpstar...
2019's Nobel Physics prize was shared by three Astrophysicists: Jim Peebles for his Big Bang cosmology plus Michel Mayor and Didier Queloz for their discovery of exoplanets. To discover life out there, we need Astrobiologists. Rocket propulsion Scientist Dr Rachel Brachman and astro-chemist Dr Michael Malaska are turning their talents towards biology and the search for extra-terrestrial life.
Polio, smallpox, measles, whooping cough - the list goes on. Vaccination has saved more human lives than other treatments. Dr David gives Dr Karl the facts on our biggest medical miracle - training our immune system to fight deadly invaders.
Dr Karl embraces Sand Talk. The first Australians have been exchanging complex concepts this way for 60,000 years. Climate Change and the nature of Time can both be discussed (in Sand Talk).Tyson Yunkaporta and Dr Karl share traditional wisdom and science. https://www.bookdepository.com/Sand-Talk-How-Indigenous-Thinking-Can-Save-World-Tyson-Yunkaporta/9781925773996...

Dr Karl talks with Matt Abbott - a flight director for 40 shuttle missions. Matt worked on the ISS Robotic arm and is now fine-tuning mission control for the upcoming Orion missions - returning to the moon and beyond. @Aquarius_Flight
Silicosis is a deadly lung condition. It is an occupational disease traditionally associated with stone masons and miners. Today new generations are at risk. From workers on infrastructure to home handy-persons cutting concrete, fine particles of silica can be inhaled without the right protection. Kate Cole tells Dr Karl how to stay safe.
Digging big holes is dangerous work. Silicosis is a cumulative and sometimes fatal disease resulting from breathing in certain types of dust from broken rocks. Kate Cole is Occupational Health and Hygiene Manager for the new Sydney Metro. She talks with Dr Karl about the history and science of dust diseases.
