Ep 19: Creationism! Can we defend it??

It took 4 billion years for the first cells to evolve into the talking, walking, podcast-making, online shitposting, creative and utterly insane humans that now populate the earth.

BUT!

Is that ACTUALLY enough time for Darwin’s theory of incremental mutation to work its slow brand of magic??? A whole lot of smart people reckon it’s not. Justin and Justin try to find out whether they have a point! Spoiler alert: they don’t.

Justin Z also talks about his own recently published research looking at the health and educational deficit faced by twins.

PLUS!

  • What makes Malcolm Gladwell so delightful?

  • Survival-based selection vs Sexual selection

  • Was the primordial soup more of a bisque or a gumbo?

Jeremy’s Iron is an excuse for two mates to geek out over science, research and publication. It’s a conversation between a biostatistician (Justin Zeltzer) and an orthopaedic surgeon (Justin Bobyn).

Ep 18: Why is it so hard to do research in Russia?

Believe it or not, we actually went to Russia to find out.

Hopefully you’ll forgive the “on-location” sound quality as we discuss the difficulties of conducting and publishing research in Russia.

We also answer the following questions:

  • What caused the mystery radioactive fog that descended on Europe in 2017?

  • Can machine learning identify autism in babies from merely analysing eye movements?

  • How does Burger King possibly have a 4.5 star google review rating

Ep 17: Justin vs Justin: Race/Off

In an experiment that would make most researchers shudder with its methodological flaws, Justin Z and Justin B go head-to-head in a winner-takes-all 50m swim sprint.

Why?

We're both in our mid 30s, single and have too much time on our hands. And with content like this its probably staying that way.

Ep 16: Will tofu give me man-boobs?

Scared of soy?? Us too.

This episode unpacks the man-boob myth and also looks at the effects of soy consumption on pre- and post-menopausal women.

Justin B grabs a strong Aeropress coffee just before the show - clearly his usual frenetic enthusiasm was going to be insufficient for this one. So we make it rain in the first half of the show as we deliver a some long overdue listener shout-outs, investigate the placebo effect, cross-examine Wim Hof,  discuss the downside of having a twin and castigate Spotify DJs.

Soy chat starts around 29mins.

Ep 15: Meditation part 2: Interview with Dylan Baskin from Qwilr

Our sophmore interview on Jeremy’s Iron is with renaissance tech bro Dylan Baskind. He’s the CEO of Qwilr - an online document-creation platform. He’s also the lead singer of Winter People and a visual artist. But what brings him to the podcast is his regular meditation habit.

We ask him how meditation affects his high pressure work life and also how regular meditation might adversely affect the creative process.

Ep 14: Why can't we prove that meditation works??

Meditation is practiced by billions across the globe. Each person with their own personal relationship to their practice. There are countless stories of meditation’s positive effect on people’s lives. From tales of rapture, to people who have come back from the brink through meditation to those that just feel that meditation makes them 10% happier.

Great! Meditation works then. Cool! No need for a podcast about it.

[resumes online shopping for bulk-buy Golden Gaytimes]

Wait. You’re saying there’s NO DEFINITIVE SCIENTIFIC EVIDENCE THAT MEDITATION WORKS? How is that possibly true? Well in this episode, Justin and Justin creep through the sticky weeds of why the effectiveness of meditation is decidedly hard to tease out. Or maybe…. just maybe… it might not be as amazing as we think!

We also talk about retired search engines, poop transplants and we announce an interview with Dylan Baskind (CEO Qwilr Industries). Note that the interview will be released as a separate episode to follow shortly!

Ep 13: Montessori and Steiner schools! Do they work??

Montessori and Steiner schools have been preaching “student-focussed” education for more than 100 years. What’s more, their rejection of teacher authority and strict curricula is progressively encroaching on mainstream schools. BUT is there any evidence that their progressive take on schooling provides any longterm benefits to students?? Justin and Justin hope to find out!

In this episode we discuss the education principles of Montessori and Steiner schools and investigate any available scientific research on long-term effects to students.

Also in this episode: Do elderberries protect you from the flu? What is the gut-brain axis? Does Justin Z have a gambling problem? Who are the other members of the band Genesis?

Ep 12: Fly Shame

So you think you’re eco-conscious hey? You don’t own a car, you keep a kitchen compost and you even reuse those brown paper mushroom bags to discretely drink your canned beer on public transport. Good for you! Unfortunately it adds up to about nothing if you take just one domestic flight.

Fly shame is real, and many people are going cold turkey on holiday making to reduce their environmental impact.

In this episode, Justin B tries to convince Justin Z not to become one of these people. We also talk about new interesting findings in evolutionary biology, how a jet engine works and the magic castle in Los Angeles.

Ep 11: Social media and addiction

Justin Z completes the Iowa gambling task, and opens up about a burgeoning interest in losing money at poker. Justin B links this to social media use. It works. Mostly.

They also talk about self-driving cars (as any self-respecting podcast ought to), and a new type of male contraception inspired by a layered cocktail.

Ep 10: Does sunscreen work??

From the age of 5 we’ve been slip slop slapping like it was going out of style. 30 years later the jury is still out as to whether the slop was really worth it. Sunscreen is getting a bad name. But is it justified??

Other questions “answered” in this podcast:

Are eggs good for you?  

Is there such thing as a common energy between humans?

Why does it always rain on me?

Is it because I lied when I was seventeen?

Ep 9: Who was Florence Nightingale?

What does The Lady of the Lamp have to do with Magic cards and Hanson’s latest live album? Well it’s unlikely that the lads from Jeremy’s Iron have offered much in the way of segue. Consider it a sort of brutalist pastiche… half the canvas devoted to trivialites, and the other half a portrait of the most significant public health figure in history.

That said, there is way more than meets the eye to Flo Jo Nightingale. She is quite a controversial figure being at once a harsh clinician and a caring confidante, a feminist and an anti-feminist.

Ep 8: Interview with Brad Wong of the Copenhagen Consensus Centre

Today we make our first interview! The (un)lucky human subjected to our line of questioning is one Brad Wong, Chief Economist at the Copenhagen Consensus Centre.

The Copenhagen Consensus Centre is a think-tank that researches the smartest solutions to the world’s biggest problems, advising policy-makers and philanthopists how to spend their money most effectively.

Ep 6: What can Bolivian hunter-gatherers tell us about a healthy diet?

The Tsimané are an indigenous people of lowland Bolivia who still remain largely isolated. We’d scoff at their low diet diversity, but their levels of heart disease and type 2 diabetes are among the lowest of any population recorded in the world. This episode is probably a good reminder that you should stop eating sherbert for breakfast.

Inspiration for this week’s episode comes from the following article:

Nutrition transition in 2 lowland Bolivian subsistence populations (2018)

Ep 5: Acupuncture. Is it just what you need(le)?

So we’ve had better puns. Some didn’t even require brackets.

Nonetheless, in this episode Justin and Justin wrangle with thousands of years of Chinese medical treatment. Mostly respectfully. Though definitely scientifically. It’s a story of Eastern philosophy meets Western standards of scientific evidence.

Ep 4: Ain't nothin but a M.S.G. thang

My mum still avoids M.S.G.

She swears that on the occasion that she lets her guard down and chomps into a chow mein, she’s instantly attacked with a slew of palpatory, perspitory symptoms that last hours. Now anyone that’s had a chow mein from Seq Fun BBQ house in Redfern will attest that this is a pretty good trade. But the question remains: is it the M.S.G or is she merely another victim of the vicious (and spreading) nocebo virus.

Have a listen and find out!

Ep 3: Are microwaves destroying the nutrients in my food?

In the third episode of Jeremy’s Iron we discuss the question that has hounded us for half a century: How do you actually set the f&%king time on a microwave? Mine’s been flashing 0:00 since 1998.

We look at the overwhelming research suggesting that microwaves are safe, sound and might even be better than your cooktop for nutrient retention. More importantly, we discuss the reasons why some people are still reluctant, decades on, to use this safe technology.

Oh, and it’s raining. Hard.

Ep 2: Will turmeric solve all of my problems?

Spoiler alert: no.

The inspiration behind this week’s podcast was an article boasting 600 reasons why turmeric may be the worlds most important herb. Sounds impressive, though none of those 600 reasons were compelling enough for turmeric to feature in the list of the top 15 most powerful herbs. Notably, the #1 herb appears to “prevent against bacterial affections”. It’s almost like these kinds of articles rely on subjective opinion, conjecture and delightful typographical errors.

None of that here! This week on Jeremy’s Iron we take to the scientific journals to see what hard evidence there is for magical healing properties of curcurmin (the active ingredient in turmeric).

With our backgrounds in medical research and medical medicine, we intend to rustle through the available research and do your homework for you.

On our maiden podcast voyage, we’re attempting to answer that age old question: “will flossing my teeth cure my impotence?”. The oldest chestnut there is. Well, it might sound spurious, but this seems to be commonly understood among holistic dental professionals. What’s an holistic dental professional?

Oh! Sorry. We’re actually asking. That’s not rhetoric. Please comment below.

In our first episode we get into the weeds with research that does indeed surprise us with the degree to which this phenomenon has been studied and supported. As always (we predict), the devil is in the scientific detail. Listen in, subscribe, and tell your buddies.
