There were high hopes for the Hubble space telescope. Eventually they were realised with pictures of galaxies beyond our widest visions. This century the James Webb promises both time and space with a different universal perspective. Dr Jessica Bloom on why this is a game changer.
The diseases of ageing are already overwhelming health care facilities. In the decades ahead, our older populations will put even more pressure on health unless there are medical breakthroughs. These diseases are proving stubborn to medicate and cures are very rare. A human fountain of youth has yet to show itself. In other animals, things appear easier to treat with less complex biochemistry to get in the way. Dr Bloom explains to Dr Karl why a family of proteins called Sirtuins may hold some h...
In 1966, two Soviet cosmologists proposed the existence of primordial black holes. 55 years on, evidence mounts that these ancient bodies actually exist. They are the stem cells of the cosmos scattered on a universal matrix and may be pre-atomic. Professor Lewis takes Dr Karl back to the very beginning for an encounter with these dark beasts. drkarl.com geraintflewis.com...
A zap from a doorknob or a lightning bolt that sets fire to a forest, these events are notoriously unpredictable. If there is an imbalance of electric charge, a Static Electricity event "might" happen. Things like air humidity or microscopic superficial bumps can play a role – but how much? Professor Lewis explains the known physics and yet-to-be discovered secret life of static electricity with Dr Karl. drkarl.com geraintflewis.com...
What happens when a star gets hungry? Could it eat another star? Cosmic cannibalism is a thing. 500 million years ago in a galaxy far, far away – to be precise, about 500 million light years away one of two stars gobbled the other. Professor Lewis explains to Dr Karl the physics and cosmology of devouring your neighbours. drkarl.com geraintflewis.com...

The 60s, 70s and 80s was when their prize-winning work was done., Their modelling made "Groundbreaking contributions to our understanding of complex systems". These Nobel physicists explored how to estimate climate changes with greenhouse gasses. Nobel-2021 drkarl.com...
Cybernetics meets anthropology - Professor Genevieve Bell loves blended disciplines. She is a renowned anthropologist, technologist, and futurist. She spent more than two decades in Silicon Valley. Her passion - making tech work better with humans and social systems. Too often technologists forget human needs or exploit weaknesses. Both can lead to disaster. Dr Karl in conversation with a progressive Australian futurist. htttps:\\drkarl.com @feraldata...
Artificial Intelligence is proliferating so how deep will it penetrate society. Are Robot domestic helpers, interpreters, navigators, lawyers or judges on their way? What about autonomous nuclear submarines? Should we be drawing lines? AI expert professor Toby Walsh has answers for Dr Karl's questions. https:\\drkarl.com @TobyWalsh...
Artificial Intelligence is here and embedded in modern life. So how best to traverse those “uncanny valleys” between robots and humans? Can computer Art or Sculpture express human feeling? Could AI math (re-factorable numbers) keep us safer? Professor Toby Walsh is an expert and has answers for Dr Karl. https:\\drkarl.com @TobyWalsh...
October 15th is Ada Lovelace Day and celebrates women in science, tech, engineering, and math. Ada was Lord Byron's daughter but most significantly she realised the potential of computers two centuries ago. Ada is now believed to be the first person to publish an algorithm. She is one of many women forgotten by science as Dr Jessica Bloom tells Dr Karl. https:/drkarl.com...
Doctor Karl talks with the Chief Scientist of Australia. Superconductors, Sunscreen, LEDs, Phonons, Vaccines - is anything off limits? In an age where science is everywhere how does a Chief Scientist operate ? https://www.chiefscientist.gov.au/ Twitter @ScienceChiefAu drkarl.com...
Dr Karl and cosmologist professor Paul Davies discuss what we are still learning about the Universe. Antigravity, inflation, Olbers' paradox, extraterrestrial life - have been eternal puzzles. Piece by piece we are assembling a bigger picture ... but is it getting any clearer ? https://drkarl.com/ https://beyond.asu.edu/ deepthought@asu.edu...
Is our universe one of a long cycle of repeating universes? Or is it something different? Dr K takes a ride with Prof Geraint through concepts of cycling universes. http://www.drkarl.com http://www.geraintflewis.com
130 million years ago marsupials roamed the earth along with dinosaurs. Today only marsupials survive. Dr Karl meets Professor Kathy Belov to discover their secrets of survival and what we are now learning from them. Anyone for koala peptides ? http://www.drkarl.com https://twitter.com/kathybelov...
Globular clusters are spherical collections of stars. The Milky Way has 150. Most galaxies have them. Professor Lewis gives an update on these freaky outliers. Are they are older and wiser residents of galactic space? http://www.drkarl.com http://www.geraintflewis.com

On Wednesdays Dr Karl meets with school students around Australia (and sometimes overseas). He loves hearing what the curious young minds are thinking about. Their questions often set off new ways of thinking. Occasionaly the simplest questions are the hardest.
