Dr Daniel Zarin has spent his career studying and teaching the science of forests. In a conversation recorded at the Wildlife Conservation Society's Bronx Zoo headquarters in New York City, Zarin tells Dr Karl why he recently left the philanthropic sector to become Executive Director for Forests and Climate at WCS and why trees are the asset we need to revalue today. drkarl.com wcs.org

Is attention-loss corroding civilisation? When we we fail to comprehend, are we putting ourselves at risk ? Dr Karl sharpens his focus on the research of Johann Hari and his new book 'Stolen Focus'.

The Antikythera Mechanism is a portable planetarium from Ancient Greece. It is 2200 years old and the first known analog computer. Dr. Nick Andronis built one. The front shows the zodiac position of the first 5 planets, sun, moon phase and date.  On the back a 72 year lunar and Olympic calendar with solar or lunar ecliplses.   www.amclock.net drkarl.com

2022 looked safe -then it wasn't . Dr Karl investigates with University of Sydney Prof Eddie Holmes. He was the first western source of the Wuhan genome. How could Omicron fool the world?  How can we avoid being fooled again?   

We are counting on an electrified future to cut carbon emissions. Greener futures, as we plan them,  depend on electricity and electro-magnetism. Dr Karl explores the physics of electricity and generators with Professor Lewis. drkarl.com geraintflewis.com

Every week new supplements are announced and promoted. Some can be useful additions to your diet but what about probiotics and prebiotics ?  Dietetics professor Collins explains what they claim, what is in them and if they help.  

Electricity is a great foundation for sustainable energy but Dr Karl discovers how little he knows about the physics of electrons. We all have much to learn about the source of power from Professor Lewis.   drkarl.com geraintflewis.com

What colour is our Sun? (or Sol as local folks call it). How long will it stay that way?  Professor Lewis resumes his fascinating journey in time space and consciousness. We pick up where things are now and go forward to the end. How does it all end? Listen with Dr Karl on this multi-trillion year trip. drkarl.com geraintflewis.com

For some stars, life begins at 10 billion years. Professor Lewis leads Dr Karl on a trillion year expedition from birth to a young adult expanding universe. The first part of a fascinating journey in time, space and consciousness.  drkarl.com geraintflewis.com

Australia has a new Antarctic Vessel. Jono Reeve takes Dr Karl on a virtual tour of the features of the RSV Nuyina.  drkarl.com RSV Nuyina

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 g...

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 D...

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

Covid continues to test public health and communications. Our best explainers have put themselves in the front line to keep us safe. Some, including Professor Julie Leask, have been threatened. Dr Karl discusses why health professionals have been under attack for doing their Job.  drkarl.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 progress...

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?
