He has addressed the General Assembly at the United Nations in New York. He is currently a plaintiff in a youth-led lawsuit against the US federal government for their failure to protect the atmosphere for future generations.
On a brief visit to Australia he talks with Dr. Karl on how to achieve meaningful change as a youth activist.
Rank #2: Autism is so diverse that researchers need a spectrum (146)
Dr Karl talks with University of Sydney researcher Marilena Demayo about the complex process of identifying and unravelling autism. @MMDeMayo
Rank #3: The Dark Side of the Universe with Prof James Green (74)
The stars at night are only a fraction of what we know should be there. So where are all those missing bits from our universe? This is a lifelong quest for Professor James Green from Colorado University in Boulder. Since his student days, he has been designing payloads for NASA rockets (and the Hubble space telescope) looking at invisible stuff. So how do you see in the cold black soup of space? What is a Sounding Rocket? Why do Wimps beat Macho's ? These and many more questions are answered in Dr Karl's latest podcast.
Rank #4: Eat your way to Happiness (145)
Research is showing that "Happy" meals are real. Not only do you feel better at the dinner table, those feelings are long lasting. Also you can amplify the good effects by how you dine. Spoiler Alert - fast food is not the answer. http://healthyeatingquiz.com.au/
Rank #5: The Source of Life, Fish and podcasts (71)
Doctor Alice on Interstellar Chemistry. Doctor Karl answers the vital question "Do Fish Drink?". Dr Almost Jessica on where it is best to listen to podcasts. A Deep edition. The Shirtloads podcast Team back for 2018.
Rank #6: 3 Doctors on Carbon, Black Holes and Car Keys (144)

Rank #8: The Ins and Outs of the Ketogenic Diet (65)
Dietitian, Care Collins gives Dr Karl a full 360 on a diet that is getting researchers pumped up. Imagine a menu that stimulated the blood brain barrier, made you think you were full early and might starve cancer cells. Sounds good but there are dangerous side effects in the long term. Ketogenic is a medical diet, is difficult to stick with and may actually have no long term weight loss benefits.
Rank #9: When Galaxies Collide (100)
30 minutes with Dr Karl and prof Lisa Harvey-Smith will turn your head around. What is our place in the Universe? Recorded live at a function for prof Lisa's "When Galaxies collide" book this is a roller coaster ride through physics, chemistry and our stellar heritage. Where was the gold in wedding rings made ? https://lisaharveysmith.com/
Rank #10: The 300 million year old Killer we are still learning about (99)
They're 300 million years old. They're almost invisible and they are deadly. Cubozoa, Box jellyfish or Irukandji, are both the smallest and the most venomous jellyfish in the world. There are more than 50 species and Dr Karl joins Lisa-ann Gershwin on her hunt for more. When Box jellyfish fire their stingers, the pain and other symptoms are collectively known as Irukandji syndrome and it can kill. But something as thin as pantyhose can save your life - how does that work ? http://lisagershwin.com
Rank #11: Longitude - Our gateway to the fourth dimension (96)
Longitude was maritime history’s greatest scientific breakthrough. Dr Karl discovers why with Kevin Sumption and James Hunter from the Australian National Maritime Museum in Sydney. What connects Lieutenant James Cook to the early computers ? Extraordinary nautical tables and accurate clocks. From these innovations space exploration was possible. (from 2016)
Rank #12: The Antarctic Treaty and Space Law (116)
An aspiring space diplomat tries to determine space law using the Antarctic Treaty. Both were set in the Cold War but the times have changed. Compare and contrast with Dr Karl and Annie.
Rank #13: How Antarctica is melting with Dr Ben Galton-Fenzi (126)
If you want to know how Global Warming works, ask a Glaciologist. Dr Karl talks with Dr Ben Galton-Fenzi about his measurements on the Totten Glacier - one of the fastest flowing in Antarctica. His measurements, models and predictions are rewriting the timetable for ocean level rises. Dr Karl traveled south to Casey research station as part of the Australian Antarctic Program. @AusAntarctic
Rank #14: How to talk Science in 2017 - Masterclass with Bill Nye (58)
Bill Nye is a household name in the United States. Former Engineer for Boeing, he has a real knack of explaining things. On the panel are Peter Lebedev (investigating how YouTube videos could be made better) and Tom Gordon from Sydney University (resident science communicator at the School of Physics). Clear and accurate communication is fundamental to Science. In 2017, how do you counter beliefs that are ultimately harmful to others and the world at large ? Fascinating discussion.
Rank #15: Understanding Econobabble (68)
Econobabble is an invented language that deliberately obscures what you think words describe. Words like "unemployment" and "subsidy" are simple at first glance. Wait till you find out what they really mean ! Are you wasting your time looking for certain jobs, investing your savings in the wrong place or voting against you best interests? Are your definitions up to date? 1962, William S. Burroughs suggested that language could be a virus in his book "The Ticket That Exploded". This 30 minute podcast might be the inoculation you've been looking for.
Note: Statistics and examples are for illustrative purposes only. Some are out of date and possibly wrong. The interview was recorded this in late 2017 before the Queensland state election.
Rank #16: Superheavy Elements pt 1 (76)
Before the Space Race began there was a chemistry race - the hunt for new elements. The Russians may have organised the periodic table but it was the Americans that began filling in the blanks. These heavy elements could not be found in nature, you had to create them in cyclotrons and reactors. Chemistry World journalist and author, Kit Chapman, tells Dr Karl about the people behind the 20 or so unpronounceable names at the bottom of the table. In this podcast we count up from atomic number 93. Who wrote a personal letter to Stalin urging a soviet atomic program ? What was the Frankenstein-like moment in San Francisco (just before Pearl Harbour) that changed the war? Which superhero prompted the raid on the offices of DC Comics ?
Rank #17: Euthenasia - Our moral and ethical dilemma (66)
If every death was a good death, then euthenasia would be widespread. Today most countries ban it. Why? Professor Linda Shields has unearthed some of the reasons and they are within living memory. She is a Professor of Rural Health and has written of an under-reported genocide. One-third of a million disabled people (adults and children, male and female, physical and intellectual) were killed during the Nazi regime and the people who did that killing were nurses. Her book is Nurses and Midwives in Nazi Germany: The "Euthanasia Programs.
Rank #18: Women who measured the stars (57)
Edwin Hubble is world famous for his discoveries. Henrietta Swan Leavitt is not. Henrietta was on a team that found a way to measure and classify the universe. They were employed as "human computers" (before the machines existed). Dava's book "The Glass Universe" refers to the half million glass slides Henrietta and other women used to document both the northern and southern skies. An inspiring story of collaboration and discovery.
Rank #19: Marine Biology Adventures (with Dr. Helen Scales) (63)
Marine biologist, diver and author Dr Helen Scales takes Dr Karl deep beneath the waves to share her passion for the ocean. Helen talks about the secret life of molluscs (shellfish). Hear about ‘clacking’ oysters, the legend of the Golden Fleece (sea silk) and a creature resembling a pinecone crossbred with a slug. There’s maths in the spirals, slave trading in the cowrie and just imagine a Harry Potter golden snitch of the sea… it’s real and plays an incredibly important role.
Rank #20: White Drink Scams . Dr Nick Fuller lifts the lids with Dr Karl (114 )
A whole new drink category has sprung up in your supermarket. The Labels say "Milk" - but what's really inside ? On the internet you'll find all kinds of nice things being said, but some of these products have hidden health hazards - like loss of bone mass, weight gain and bad cholesterol buildup. Some are just lousy value for money. Dr Nick lists the healthy and economical choices for every diet. Twitter: @drnickfuller Website: www.intervalweightloss.com.au
