Dr Karl’s a curious optimist – a great combination for a science lover. Join him and his guests for weird facts, amazing conversation and remember, it’s never too late for a happy childhood.
Value of a Life with Richard Denniss (225) RPTCovid19 is revealing stark truths. The preservation of human life is both economic and cultural. Is there a better path ? Dr Karl discusses the value of a human life with Australian economist Dr. Richard Denniss. Both sides of the balance sheet have merit.
Ethical Food with Professor McClements (212) RPTEating ethically may become compulsory. If climate change escalates as estimated, carbon-intensive animals and crops may need to be rationed. Food scientist, Professor David Julian McClements, is optimistic that solutions may be at hand. Could we engineer less carbonised food and design a healthier diet ? Dr Karl samples the future of food.
Mars #2 with Dr Adrian Brown (321)On the surface of Mars, the NASA Perseverance Rover is bottling rocks to be returned to Earth. How will they get back? Why are the samples so valuable? Dr Brown, Australian Scientist with the mission, has the latest news in the second part of his discussion with Dr Karl.
Mars #1 with Dr Adrian Brown (320)While planet earth was in Covid lockdown, a NASA spacecraft left for Mars. Perseverance ("Percy" to its friends) is on a mission to unlock planetary secrets. Dr Adrian Brown gives Dr Karl the latest news from the Martian surface.
Coral Health with Dr. Wachenfeld (319)The world's largest coral reef is in trouble. Chief Scientist for Australia’s Great Barrier Reef, Dr Wachenfeld, talks with Dr Karl about what he is seeing. Twenty five years ago waves of hot water were first measured. They continue with intensity. Will the COP Accords be enough to save our reefs?
Dark Matter & Neutrinos with Professor Marcela Carena (318)Particle physics is making discoveries each day. Professor Carena gives Dr Karl the latest on the relationship between dark matter and neutrinos. It is part of her lecture on Mon 5th Dec 5.45pm Messel Theatre, Physics Road Sydney University.
Beyond Higgs with Professor Marcela Carena (317)Particle physics is amazing science. Professor Carena works at the edge and gives Dr Karl a sneak preview of her lecture and why those bosons matter.
Arthritis supplements with Professor Collins (316)Someone you know is being treatmed for Arthritis. 15% of Australians suffer pain daily and there are few safe drugs. This has led to shelf loads of "supplements" and "alternatives". Does any of it work? Professor Collins compiles the best research to date. Most do nothing (so don't waste your health, time or money).
The cost of Cancer with Professor Tindle (315)The last thing you expect to see at an oncology ward is a cash machine. Professor Robert Tindle discusses the unequal and sometimes unfair cost of treating cancer. Is your cancer is common ? Did a drug company successfully navigate the health system? In Australia the difference can be enormous. His book is called "your cash or your cancer."
Invisible Infrared: James Webb Space Telescope with Professor Tuthill (314)Professor Peter Tuthill and Dr Karl live on stage at Sydney Ideas. They peel back how and why the James Webb Space Telescope (our Infrared Eye in the sky) has keys for survival. Earth is already out of balance with an extra 600,000 Hiroshima atom-bombs of heat every day. The good news? Climate change is measurable and can be stopped.
Breakfast of Champions with Dr Nick Fuller (313)If Antimatter exists, why isn't there anti-food ? Stuff you can eat to lose weight. Dr Fuller has discovered interesting results from 2020 research based om thermogenis. This is not a diet. It won't take weight off but it could cut weight gain by 250%.
Converge with Dr. Catherine Ball (312)20th century futurists spoke of tech convergence as a good thing. Data is now omnipresent but what of the scocial changes. In "Converge" Dr. Catherine Ball gives Dr Karl a spot check on where we are and some good nwews on where we are heading.
5 Numbers with Professor Lewis (311)Are there more questions than answers ? Dr Karl probes prof. Lewis on 5 numbers from a Science magazine. How much (or little)do we know ?
Aussie Aerospace with Taylah Griffiths (310)
Psychedelic therapies with Dr. Bahceci (309)Psychedelic drugs in the 50s & 60s offered hope for relief from some mental illnesses. Lawful access to these chemicals was shut off in 1971 by US President Nixon. Fifty years later the science is mounting for their therapeutic use. Dr. Bahceci works in this area and explains to Dr Karl the latest research. This podcast discusses mental health and suicide. Some may find this confronting or distressing. If this material raises concerns for you, please contact Lifeline on 13 11 14 or Beyond Blue on 1300 224 636
New Covid Vaccines with Dr Steain (308)Could 2023 be the year we stopped the Covid ? Dr Karl meets a Sydney virologist working on this mission. Dr Steains gives a viral history of the past three years and an outline of her project to develop better vaccines.
Space Comms with Dr. Badri Younes (307)Space exploration needs good communication. Dr. Karl grills NASA veteran Dr. Younes.
Starbursts with Dr Adele Goodwin (306)Their guts are called Nuclear Pasta. You need X-Ray space telescopes to capture their burps. Observations take kiloseconds. What kind of stellar monsters are inhabiting our galaxy ? Dr Adele Goodwin gives Dr Karl of an insight.
Monopoles & Inflation with Prof Lewis (305)Monopoles and Inflation are Cosmic. Professor Lewis shows Dr. Karl their theoretical universal origins.
Our biggest Space Telescope with Professor Lewis (304)There are more than a new set of lenses on the JWST. It has better eyes, a giant sun-sheild and a new brain. Professor Lewis helps Dr Karl interpret the astounding imagaes coming from our Lagrange point.
