In 2020, Scientific American made waves with the provocative headline: "No One Can Explain Why Planes Stay in the Air." But is that really true? Dr. Graham Wild, senior lecturer in aviation science and technology at the University of New South Wales in Canberra, joins us to set the record straight. In this episode, we dip our toes into the complex world of flight. We scratch at the very surface of the topic in an episode that could easily take over 20 hours.

Most of us throw our clothes in the wash without a second thought, but what if that habit is doing more harm than good? In this episode, Dr. Holly Kaye-Smith, social change expert and communications specialist, challenges the way we think about cleanliness, climate action, and everyday laundry. From surprising stats (over 90% of washed clothes aren’t even dirty!) to the hidden environmental cost of every wash cycle, we dive into the myths, microplastics, and mindsets that shape our laundering routines. Holly shares practical refreshing techniques that save water, and why she recommends everyone have a “rewear chair.” Connect with Dr Holly Kaye Smith on Linkedin Instagram - www.instagram.com/drhollyphd/ Youtube - www.youtube.com/@drhollyphd
Are ice baths really the recovery miracle they're made out to be? We plunge into the science with Dr. Hunter Bennett, lecturer at the University of South Australia, exploring the pros and cons of ice baths, when they’re helpful, and when they might actually hinder your gains. We also unpack health misinformation online and Dr Hunter shares five evidence-based tips for anyone curious about cold plunges.

Dr. Brooke Nickel dives into the murky world of health misinformation on social media, exposing how overdiagnosis and unverified health claims are thriving in a mostly unregulated space. We explore the influence of online personalities, the power of personal anecdotes, and the urgent need for evidence-based guidance in digital health conversations. 🔗 Connect with Dr. Brooke Nickel on LinkedIn
Award-winning author and investigative journalist Alice Driver joins me to discuss her powerful new book, Life and Death of the American Worker. Her investigation exposes the deeply unethical practices within the meatpacking industry in the United States. For Alice, this story is personal. She grew up in Arkansas, one of the country’s poorest states and home to Tyson Foods, the largest meatpacking plant in America. We delve into the harsh realities faced by the industry’s workforce, many of whom are undocumented immigrants, with estimates suggesting that up to 30% of the labor force lacks legal status. Our conversation explores the severe health consequences these workers endure and the broader implications for workers’ rights in America today.

FFS! Don't you guys read these comments about your podcast? I've pointed out previously that the sound level is really low compared to other podcasts and the previous episode was muted for one ear. And still you pump out another episode that I strain to hear. If the next one is not up to standard, I will unsubscribe.
Can you guys sort out your sound editing. The last few episodes have had very faint sound, and one I'm listening to now is not only very faint but the discussion is audible only on the left channel. Don't you even check things before and after dropping an episode? Compare your audio volume to that of a hand full of other podcasts to see if you're even in the ball park. (which you're not, btw)
Hmm, so Karl totally marvels at the science involved in developing the artificial ear drum, but upon hearing the description of how the ear is constucted and how the ear drum repairs itself the credit suddenly goes to mindless evolution rather than the Master Designer. (aka God the Creator.) Seems like Karl has a blindness problem!
He spoke so fast!!!!!
Lately the sound quality is atrocious, like he's recording it on a potato stuck in his back pocket.
If dinosaurs evolved into birds, explain how reptilian scales skin (which is shed all at once as a skin layer) evolved into complex feathers which grow out of follicles and which shed in pairs gradually, to maintain flight balance while feathers are replaced.
If dinosaurs evolved into birds, explain how they change step by step from cold blooded to warm blooded creatures, and from heavy solid boned creatures to ones with lightweight hollow bones, again without becoming less fit at any step along the way.
If dinosaurs evolved into birds, explain how the dinosaur's bellows type lung evolved step by tiny step into the flow-thru lung of birds without the creature becoming less fit throughout that journey. Alternatively, explain how a plane with piston engine and propeller can change bit by bit into a plane with a jet engine, without becoming less able to fly throughout that metamorphosis.
just found doctor Carl again. haven't heard him for years. looking forward to listening to him again
It's odd that after discussing the features that make life on Earth possible for us, with all the fine tuning etc, that Dr Karl and Dr Lewis can't see that it looks like someone took great care to design a safe and stable habitat for us. And when asked how life could have got started, Dr Lewis spoke about environmental conditions but never even touched upon the biochemical hurdles, such as needing numerous molecular machines in place and functioning to get self-replication, which the allows...
OMG this is insanity! Prof Lewis claims that we rarely see a smashed glass come back together and reassemble itself! (RARELY...? Has anyone in all of history EVER seen this?!) But he claims it is possible! All this nonsense (non-science!) just to avoid the implication that evolution is impossible because natural forces cannot create ordered complexity. Only an intelligent mind can do that. For much better explanations, search for articles about entropy on www.creation.com
OMG what drugs is this prof Gisela Kaplan taking?! She said "You never get anything in evolution unless it's absolutely necessary for the survival of the species." So how does painting beautiful pictures help us survive? Or composing music? Or playing the violin? Or performing a dance routine? Or ride a unicycle? Or work out abstract mathematics? Or how does a peacock's tail plumage help it survive? (The females don't choose mates based on tail plumage.) These evolutionists are mad!
His female guest made the comment that wherever on Earth we find water we find life, then makes the leap to wherever in the universe we find water we're likely to find life. Wrong! Finding life on Earth always in the presence of water shows that water is NECESSARY to SUSTAIN life, but it doesn't mean that the presence of water is SUFFICIENT to ORIGINATE life. The molecular machinery in living cells shows clear signs of very clever design, pointing to a very clever Designer.
"Mother Nature is the best chemist..." said by Karl's guest after marveling over molecular machines and such. So "nature" is ascribed anthropomorphic qualities such as knowledge, wisdom, foresight, and planning, to produce all this marvellous biochemistry. Yet they're blind to the much more sensible notion of an intelligent Creator God, a BEING with a mind, an intellect, knowledge, wisdom,and ability to plan and create the entire biosphere. (as well as the universe in which it resides.)
Dr Karl's guest made a comment that's illogical and unscientific. He said that the fact that all living things speak the same language of DNA proves that all life evolved from a single primordial cell. That's like saying that since all cars use the same set of metric threaded bolts proves they're all made at a single factory somewhere. Not logical, as there could be other explanations for this. The common DNA language can equally be explained by a common DESIGNER, also known as the CREATOR GOD.
this guy is wrong, the instant asset write off is specifically for tradies and utes, it's for any eligible asset. I know a number of people who have specifically obtained the instant write off on electric vehicles.
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.
So entertaining to listen to. Great podcasts Dr Karl. they help to keep me sane in my post covid job. I did just Google Jessica Bloom too. Nothing more I can say!
super interesting & enjoyable
