Celebrities often support pills, potions and creams that purport to make you look younger. What about dietary supplements for your skin ? Jennifer Aniston became the face of one brand’s collagen campaign recently. Is there any science in it ? Professor  Claire Collins tells Dr Karl.  the conversation nomoneynotime
Dietician Professor Clare Collins gives this celebrity diet expert analysis. UK singer Adele claimed it transformed her (along with Pilates and a personal trainer). The diet is based on a group of proteins called "Sirtuins". Adele sang its praises but is Sirtfood a fad, a fact or something in-between? the conversation    
What is inside the heart of an atom ? Why does it stay together ? The relative dimensions of atoms are huge - Imagine a fly in a cathedral (the fly is a nucleus). Professor Lewis takes Dr Karl on a journey to the center of matter as we know it.
Dr Karl visits Dr Nick to compare two currently popular diets - the Low carbohydrate and the Ketogenic diet. . Dr Fuller talks through the basics of both and and what you can do to make lasting healthy changes. @drnickfuller
Taxonomy is how science classifies life. Sage Fitzgerald is a coral taxonomist and in  this episode she schools Dr Karl on how it works. They discuss the phoenix project and the chase for new coral species and news from the Great Barrier Reef.  Sage is also involved in the ‘Pint O Science’ Festival running until 28 May 2021. @seasciencesage
Dr Karl visits Dr Nick for an analysis of the latest diets. In Covid times it is harder to stay in shape. Dr Fuller talks through the basics and what we can do to make healthy changes that last. @drnickfuller
An interview with one of the pilots of a 10.9 km dive into the Mariana Trench. It is deeper than Everest is high . The two-seat submersible is capable of withstanding huge forces and Dr Karl discusses the extreme physics and engineering needed to build and test the craft.  
When subatomic particles make news, Dr Karl and Professor Lewis are ready to help. The "chubby electron" has been neglected for decades, so why the fuss ? By popular request here is a special episode dedicated to why muons matter.  
What happens when the temperature seriously drops? Will "Dead Star" be more than a David Bowie album? Are protons the new Time lords? How Cool is a cool Universe ? Proessor Lewis updates Dr Karl on what the end of time miht look like.

Covid19 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.
When atoms were smashed, particle physics went nuts. The subatomic domain should describe everything but so many  pieces are missing. Dr. Karl and Professor Lewis look inside the atom in this podcast. So what the flip is subatomic particle physics ?  
Our lives are governed by physics.  It is the science of matter and energy and without both we wouldn't be here. This past century we have discovered more about physics than ever before. Dr. Karl and Professor Lewis are going atomic in this podcast. So what the flip is particle physics ?
A disease has infected our civilisation. It is not a virus but we created it. Dr Richard Denniss calls it "Affluenza" and it may ruin everything if we don't fix it soon. @RDennisTwitter Curing Affluenza
Australia is sunny and flat. It should be the perfect place for Electric Vehicles. So why are Australians so slow to buy them ? Dr Karl asks lead journalist, Bridie Schmidt,  from newsletter about the sluggish takeup downunder.  
Dr Karl has a thought experiment for Professor Lewis. What if you could travel at one Earth G (9.8 m/s^2). How far could you go in one human lifetime ? The answer and explanation will astound you. 
Boundless. Limitless. The concept of Infinity has been with us for millennia. Dr Jessica leads Dr Karl on some mind experiments to see how our finite minds comprehend the universal.  
Four popular diets.  Professor Collins gives two a conditional tick. It's Fast vs Mono vs Noom vs Charcoal. Can you pick the best ? Years of expertise sorts the dangerous from the reliable - rpt the conversation

Please could Dr Claire take us through the basics of calcium and phosphorus metabolism?

This is the worst podcast I've listened to in a long time, lots of out dated views straight out of the 80's. Very disapointing Dr Karl, I thought u would have followed the science instead of this rot.

For the first time ever in my 70 year life I now understand why there is also a high tide on the side away from the moon! I have been pondering this for at least 50 years! Now I can visualise it.
