Hi, I'm Wendy Zuckerman, and you're listening to Science Verses.
And you know what's absolutely bonkers?
I've been saying those words to you all for 10 years.
That's right. This show that you are listening to right now, Science Verses,
it's celebrating its 10th birthday this year.
And so a few months ago, we invited you.
our listeners to send us some voice mails with your thoughts on the show my name is oliver i am from
mexico this is mallee from denver colorado my name is elaine a Brazilian biologist living in new zealand
just wanted to leave a message here to express my appreciation of your show i see it's your birthday
coming pretty soon and just wanted to wish you a happy birthday science versus i absolutely love it
i have enjoyed every single pun-tastic episode i got instantly hooked much like
My favorite pint of ice cream, you guys, as soon as I see you, I just have to inhale.
It was really amazing hearing about all the things that you'd learned from the show
and how, in some cases, the science really shook things up for you.
There is an episode of Science Verses that still haunts me to this day,
and it's the episode of brushing your teeth.
I feel like ever since I heard that episode, I've lost all faith in the institution of toothbrushing.
I've always been a little bit blazee about microplastics,
but now I have two little daughters,
and the new evidence linking female hormones to microplastics
really scared me a bit.
I remember one episode that was something that marked me,
and that was one where you talked about a pandemic
and the potential implications of a pandemic in the...
And then, well, it COVID happened.
Yeah, and for a while, everyone thought we were witches,
which maybe we are, science witches.
Thank you to the teacher who uses our episodes for her classroom.
Just wanted to say hello to the family who listened to us
while driving in the dark to a volcano in Hawaii.
I wish I could have been there for real.
To those who are eating more fiber and doing more journaling,
thanks to our episodes, I hope it's working for you
and that your poos and your mind are feeling better,
to the dad who found out his daughter had Alice in Wonderland syndrome
with the help of our episode.
I'm just really happy we could help.
And thank you to this listener who told us about another episode
that hit in a very different way.
It was our episode on cannabis.
So for a long time, I personally decided that it's not really for me.
I'm not going to do that.
but I always find it really difficult
as it's getting more popular and more popular.
For context, my mum has, like, a psychosis sort of
that was, I guess, triggered a little bit by marijuana.
And I, listening to this episode made me feel really, really secure
in my personal choices to not smoke a pot.
And so thank you for that.
I appreciate it.
Thank you to everyone who called in, and who's been listening to the show.
After the break, we've got some real treats for you.
We're going to share some science versus moments that were a huge deal for us.
Plus, something a lot of you probably haven't heard before.
It's the pilot episode of Science Verses, and it's about the paleo diet.
Remember this diet?
So we're going to find out if we should all be eating like cavemen.
It's all coming up.
At Desjardin, we speak business.
We speak equipment modernization.
We're fluent in data digitization and expansion into foreign markets.
And we can talk all day about streamlining manufacturing processes.
Because at Desjardin business, we speak the same language.
you do, business. So join the more than 400,000 Canadian entrepreneurs who already count on us,
and contact Desjardin today. We'd love to talk, business. This episode is brought to you by
Square. You're not just running a restaurant, you're building something big, and Square's there for all
of it, giving your customers more ways to order, whether that's in-person with Square kiosk or online.
instant access to your sales plus the funding you need to go even bigger
and real-time insights so you know what's working what's not and what's next
because when you're doing big things your tools should to visit square.ca to get
started welcome back today we're taking a little trip down memory lane to talk
about some of the highlights of the past decade of science verses so since 2015
we've made around 250 episodes diving deep on the science of all sorts of things.
Diseases, drugs, diets, plus some stuff that really freaked people out
before basically falling off the radar, like 5G.
Remember when people were afraid of that?
So now we're going to talk about a couple of major moments for us.
And first up, the orgasm gap.
which is this idea that when cis men and cis women have sex with each other,
the men are way more likely to have an orgasm than the women are.
We did an episode on this way back in 2020
when the show was an unruly five-year-old.
It was a very fun episode.
But we wanted to talk about it today
because this was the first time that Science Versus did our own research for the show.
We saw that there really wasn't much science,
around the orgasm gap for folks who are queer or trans.
And so we surveyed you guys, our listeners.
More than 5,000 of you responded, which was totally amazing.
And then we worked with sex researchers from Queen's University in Canada to analyze what we found.
And just this year, the research got published in a peer-reviewed journal.
Talk about a climax.
Now we're going to play a little bit of that original.
original orgasm gap episode. Enjoy.
Okay, our first stop is to figure out what exactly is going on when we have an orgasm.
And for that, we're starting with the biggest, most powerful, throbbing, vainy sex organ.
Um, the brain. The brain. This is Nan Wise. She was a clinician helping people with their sex
lives for decades. But there was something missing in her understanding of sex. And so?
And went back to grad school to become a neuroscientist when I turned 50. When Nan finished
grad school, she set up one of the only studies we have looking at what's going on in the brain
during an orgasm. Because she wanted to see what's firing when we're all fired up.
First up, Nan got 14 women who said they were up for having an orgasm while in an MRI.
But right away, Nan hit this big problem.
The number one enemy in brain studies is movement.
To get a clean scan in an MRI, your head needs to be perfectly still, which is a bit tough
when you're having a wank.
So, Nan had to invent something that the women would wear on their heads to keep it still.
And after a couple of years of trying to be able to.
trial and error, she settled on the design.
With what we called the Hannibal Hector Happy Helmet.
The Hannibal!
And it really was a scary-looking contraction.
Nan used plastic that molded to the shape of each subject's head
and then cut out the eye and nose holes.
It kind of looks like having your head wrapped in white construction fencing,
or like your Kanye on the Yeezer's tour.
So imagine, you're lying in this MRI, head all cased up,
And inside an MRI?
It's loud, loud, loud.
It kind of sounds like...
Boom, boom, boom, bum, bum, bum, bum, bum, bum, bum, bum, bum, bum, bum.
So, they put in earplugs.
And now, it's orgasm time.
The women in the study are lying down with their head in the MRI
and the lower half of their body is out of the scanner.
In part of Nan's experiment, she had the women's partners touch their genitals until they came.
but there were complications here too
with the women stuck in the MRI
with the ear plugs in and that loud noise
the couples couldn't talk to each other
so the women in the scanner would have to press a button
to say they've started orgasming
and Nan would then relay that to the partners
who were wearing headphones
that partner would hear your partner is having an orgasm
then the participant would press a button
orgasm was finished and the partner would hear stop stimulating your partner's orgasm is complete
oh my gosh so these partners have your voice in their ear while they are trying to give their
partners an orgasm right so I sounded a bit like a deranged I guess stewardess
so tell me do you think that you could orgasm in that situation I had to I was the
test pilot for everything. I had more orgasms in that scanner to the point that I should have frequent
flyer miles. And I actually had a very funny incident when I was in the scanner using a purple
dildo. And it slipped out of my hands and it went flying. So after the scanner went off, I said,
Houston, we have a problem. The dildo went into orbit.
That was from our episode called Orgasms Come for the Science. You should definitely go back
and have a listen to the rest if you haven't heard it. It's a banger. And you can find our
new scientific paper in the journal Psychology and Sexuality. We'll link to it in the citations, of course.
But now we're going to shift to something that's not nearly as sexy, though it still gets our knickers in a twist.
Vaccines.
So back in 2017, we first looked into the science of whether vaccines, and in particular, the measles, mumps, and rebella vaccine, or MMR, causes autism.
And it's something that I didn't think we'd still be talking about almost 10 years later.
but this claim just won't die.
In fact, earlier this month, the CDC changed its website
to suggest that the evidence on vaccines and autism
is still murky, which doesn't track with the science.
So we're going to play a bit of our original episode about this,
and just to set it up,
the idea that vaccines cause autism was first championed by a British doctor
called Andrew Wakefield.
He's since become a big campaigner against vaccines.
But he wasn't like that in the 1990s.
Back in the late 1990s, Andrew was quite different.
He was a gastroenterologist working at the Royal Free Hospital and School of Medicine in London.
And his research, which connected the measles, mumps and rebella vaccine to autism,
was being published in a prestigious journal, The Lancet, and it was being taken seriously.
So, let's take a close look at it.
Andrew and his colleagues studied 12 kids,
some of whose parents said that they had gotten autism
soon after getting the vaccine.
Now, specifically, Andrew was looking at the kids' guts
and he found that some of them had a bit of inflammation in there.
Now, from that, he thought,
ha-ha, that vaccine must have caused the inflammation,
which then led to their autism.
Now, even though this was a really small study, which when you think about it, it didn't
really prove anything, Andrew drummed up a lot of media attention and started telling
parents not to vaccinate their kids with the measles, mumps and rebella vaccine, also called
the MMR.
He hears on ABC News.
There is a great deal of evidence stacking up to suggest that the parents, their contention
that their child regressed after MMR, is indeed correct.
Scientists scrambled to figure out.
if Andrew was right and that the measles, mumps and rebella shot could cause autism.
The first studies that put Andrew's theory to the test came out about a year later.
And while that's fast in the world of science, it wasn't fast enough.
Science takes time. I think that time was not on our side.
Daniel Salmon is a professor of public health at Johns Hopkins University.
And he says those studies were too late for public opinion.
If we would have had good solid data sooner, I suspect that public concerns wouldn't have grown as quickly as they did.
And people might have been reassured by those data.
One of the first follow-up studies looked at every kid diagnosed with autism in a part of the UK.
This was almost 500 kids.
And it found no link between the measles, mumps and rebella vaccine and autism.
Soon, more and more studies would come out, involving well over a million,
children, all showing no connection between getting the vaccine and kids getting autism.
Those studies were done by different investigators, different scientists, in different countries
using different methods, and they were all negative.
Meanwhile, Andrew Wakefield's original paper was retracted.
It turned out that he had messed around with facts about the patient's medical histories,
and by 2011, an editorial in the British Medical Journal called,
the paper, quote, fatally flawed both scientifically and ethically, end quote.
That was from our 2017 episode, Vaccines Are They Safe?
And it's been really interesting for us thinking back over the past 10 years and just really
thinking about how the fight against dodgy information on.
online has just gotten so big with the rise of social media and new media like podcasts.
It's just brought this onslaught of garbage that in many cases seems to have this glow of
science around it. And part of what we're trying to do on the show is to, of course,
help you understand what's real and what's not. But also to show you where some of the
misinformation that you're seeing is coming from and why it's so easy for even really smart
people to get sucked in. And as we were looking back on all of our episodes, one stood out as
being a really clear example of that. It's our episode on Ivermectin, which is this drug that's been
used for a long time to treat stuff like parasitic worms and scabies. But some doctors got really
excited that it could also help folks with COVID. And one of those doctors was Dr. Pierre
Corey. He became a big believer in Ivermectin, talked it up in places like the US Senate and
on Joe Rogan's podcast. But it turned out that lots of this hype was based on early studies,
some of which ended up being a bit dodgy, possibly even fraudulent. And when we got better studies
later on with thousands of people.
We found out that Ivermectin did not work for COVID.
But when I talked about all of this
with Dr. Pierre Corey for our episode,
he just couldn't believe that newer science
telling us Ivermectin didn't work.
And so what would you need to see
to not believe that ivermectin works here oh i love that question i would have to unsee the hundreds of
patients that i saw over the past year so that would be the short answer to your question so i'd have to
pretend that i didn't treat them the studies are overwhelmed right so nothing so nothing nothing like
i i don't understand i don't understand like how you can ask me so the re actually i'll tell you
why you're asking that question because you are in a world where ivermectin is on
unproven. So you might get this wrong, Dr. Corey. And so what would it take for you to admit that
you're wrong? And I'm sorry, I don't have an answer for that. I don't know about being wrong.
I know it's effective. You don't know, I don't know. I'm done with that question. I think I answered
it. To get me to believe that it doesn't work, to get me to believe it does work is just an
empty exercise. I can't pretend that you can do that. Right. We spoke for all.
almost two hours.
Okay, here's the deal.
And now I'm just going to speak plainly,
and I really don't care what you or your listeners think, okay?
You can just write me off as a completely biased clinician
who's so committed to Ivermetic, he can't see anymore.
I'm fine with that.
And you know what?
Conclude that it doesn't work and make sure that no one else uses it.
That's exactly what they want to have happened.
This is a war on repurposed drugs.
But what if it's not?
What if it's not?
Like, what if you remove, what if you remove the conspiracy?
I won't do it anymore.
So, Wendy, can I just say that this is where probably our conversation will end
because I can no longer pretend that's the case.
And there's no way you can ask me to do that.
And let's just leave it as on this subject should be undetermined.
So Dr. Corey thinks everything's a conspiracy
and he's refusing to look at high quality data that shows it doesn't work.
So either I've lost my mind as a conspiracy theorist or you're a victim.
of propaganda. There's the only two conclusions. And it's my opinion, it's my opinion that you
are, you're an unfortunate victim of relentless propaganda as well as the doctors you talk to.
And what's my opinion? That I'm someone who's lost in conspiracy theory. And that's fine.
You, you are thinking that this is all a mass delusion, that everyone was a little enthusiastic
and they decided to study it and their biases led to some false conclusion that it worked.
And that's a really cute story, but it's just not true.
After chatting with Pierre Corey, me and the science versus team,
I actually looked at all of this again to see, did we miss something?
Had we been taken for a ride?
And what's clear is that Ivermectin is not a blockbuster drug for COVID.
Whatever is going on with Ivermectin,
it's not saving bucket loads of really sick people.
If it was, we'd see it clearly in the data and we don't.
and you know there are more trials coming along so we'll wait and see what they say but for now
the best data we have tells us that ivermectin really isn't doing much here and the thing is
i don't need a conspiracy theory to explain any of this because i've heard this story before
many times
that science gets excited about a drug
there's a flurry of research
and what comes out is that we realize
nah, it doesn't work
grab a beer with anyone studying cancer
or Alzheimer's
and they'll tell you a story like that
in fact
it's kind of the story I've come to expect
that is
science versus
That's from our episode, Ivermectin, the story of a wonder drug.
After the break, should you go on the paleo diet?
We go way back in the Science Versus time machine to our pilot episode.
Plus, stick around for one of our all-time favorite moments from 10 years of science verses.

The Infinite Monkey Cage returns imminently. I am Robert Ince and I'm sat next to Brian Cox
who has so much to tell you about what's on the new series. Primarily Eels.
And what else? It was fascinating, though, the Eels.
But we're not just doing Eels, are we? We're doing a bit. We did it. Brain computer
interfaces, timekeeping, fusion, monkey business, cloud, signs of the North Pole, and Eels.
Did I mention the Eels? Is this ever since you bought that timeshare underneath the Segas O.C?
Listen on BBC.com or wherever you get your podcasts.
Welcome back.
Here's to the 10th anniversary of Science Verses.
Thank you so much for listening.
I know I've said that a few times in this episode,
but I really do appreciate it.
So on this show over the years,
we've covered a lot of diets from keto to veganism to fasting,
fears around ultra-processed foods,
and seed oils.
And it's interesting because the very first episode of Science Versus was a diet episode.
As I mentioned, it was about the paleo diet, which is this idea that we should all be eating
like our cave dwelling ancestors.
And so we're going to play it for you now.
This episode was published with the Australian Broadcasting Corporation, which is where
Science Versus started.
And so I just want to thank the ABC so much for letting us publish it today.
And thank you for letting me start Science Verses.
I wouldn't be on this journey without you.
So thanks to the ABC.
All right, let's jump in.
Here's where it all began.
Welcome to Science Verses, the show where we pit fact against fad.
I'm Wendy Zuckerman.
And today, we're dissecting the paleo diet.
Researchers have been celebrating a breakthrough.
A eureka discovery.
This is a significant breakthrough.
Uncovering the sinister secrets.
Dietists across the world first.
This is the idea that if you eat like our ancestors did in Paleolithic times,
you can lose weight, stave off illness and live at the peak of health.
Now followers say they are shedding drastic amounts of weight
and are warding off debilitating diseases.
The caveman diet is the most Google diet on the planet.
We need to eat the way.
nature intended us to eat. The paleo diet is described by some as a fad, a marketing
ploy. It's offering a different paradigm from what is considered the norm. So it's going to get
shut down a little bit. Amidst the cave madness, we're about to find out if this diet is healthy
and whether we should all be on it. But first, what even is the paleo diet? Well, the original
prescription by Dr. Lauren Cordane, who wrote the paleo diet, said that our diet should
consists of lean meats, fish, leafy greens, nuts, berries.
That's Daryl Edwards. He's a paleo advocate and author of the book, Paleo Fitness.
And we should eschew, processed foods, unnecessary sugar and sweetness, and avoid antinutrients.
Anti-nutrients. We'll get to those a little later.
Now also, paleo fans completely cut out dairy because paleo people didn't have cows.
I don't eat any dairy at all.
And also, no legumes. So this means no cheese, no chickpeas.
No palakpaneer for you, none of that.
And that's all fine.
But then, there's science.
Officially, the Paleolithic period begins around 2.5 million years ago.
No, T-Rex was dead long before this.
Okay, and it goes until around 10,000 years ago.
Really, before we figured out agriculture.
So what were our early ancestors eating back then?
So I would assume they would have eaten quite a lot of plant foods, probably fruits, seeds.
They turned increasingly to animal source foods.
This is Catherine Milton.
She's a professor at the University of California in Berkeley.
And when it comes to knowing what our ancestors ate, she's one of the best in the business.
So I went to Brazil, and over about 15-year period, I was able to work with seven different
indigenous groups in the Brazilian Amazon
who had been very little contacted by outsiders.
She's also studied non-human primates
to get an idea about what our monkey cousins were eating.
So what does our primatologists think of the paleo diet?
Well, the thing is, I honestly don't know what people mean
when they talk about the paleo diet
because there were hundreds of different paleo diets.
Because people were eating what was around them.
So if you lived near the ocean, you'd be eating lots of fish,
lived in the Andes Mountains, you might have been eating cashews.
And this means that when people say they're going paleo,
they're not eating a diet that resembles what one person living in Paleolithic times
would have eaten.
They're getting their apples, maybe from the Middle East,
their avocados from Mexico, Barramundi from Northern Australia.
I mean, this is a travelling, traveling caveman.
But the thing you have to understand is that if someone is a hunter-gatherer,
which is what our ostensibly paleo ancestors were,
That means they are eating only wild plant foods and wild animal foods.
So it would be, I would think, extremely difficult for anyone, you know, with a normal job or anything in the United States to fancy that they were eating anything remotely similar to a quote, any of the, quote, paleolithic diets.
But when I put this to Daryl Edwards, our paleo advocate, he actually had a pretty convincing answer, I thought.
Did they eat broccoli 50,000 years ago?
Probably not.
It was probably a wild variant of the modern-day broccoli plant.
But we do know the classification that will mimic the paleo lifestyle.
But Catherine is quite adamant that any food you get today
is so far removed from what cave people would have been eating
that you should really just forget this idea that you're eating paleo at all.
She even says...
The paleo diet just seemed to me to be very counter our problem.
primate heritage, very counter our digestive physiology and unlikely to provide us with much other
than the fact that staying away from processed materials is probably a very good idea.
Plus, the paleo diet excludes potatoes.
You laugh?
Well, I just laugh because of the enormous amounts of potatoes that are consumed in the
Andes and Highland, New Guinea, and so on.
I mean, they would be quite shocked if they knew they could.
couldn't have the yam or the sweet potato or the solanaceous potato.
Other things that are no-nosed, grains are another one.
Well, you know what they say, take away the grains
and 80% of the world's population will be gone within a few weeks.
So, you know, it's kind of ludicrous, really.
Conclusion, this so-called paleo diet is not paleolithic.
And you know what?
even Daryl Edwards, who wrote the book Paleo Fitness,
acknowledges this.
Paleolithic or the paleo is just a label that best describes what we're aiming for.
But we don't have to go that far back.
We can go back just a few generations and realize that some of the foods
that have been very recently introduced to us.
I mean, even in the last 20, 30 years,
there will have been a lot of foods and lot of artificial sweetness
and preservatives and the like that we have no idea of what they're,
or we do have a great idea.
to what they're doing to our health today.
So just going back a few generations, in my opinion,
would be good enough for most people.
I'm not sure that you can sneak out of this so easily, though,
because the thrust behind this paleo diet argues
that humans take tens of thousands of years to evolve
so that they can eat certain foods.
And if it's okay to just go back a few generations,
then that's a different philosophy, isn't it?
Which takes us to our next question.
Is this so-called paleo diet even healthy?
Because while the elimination of some processed foods is a good thing,
there are other foods that are excluded from this diet.
Like dairy, it's a no-no,
because two million years ago, we hadn't domesticated cows yet.
My calcium I get from sardines with the bones, a great source of calcium.
I also get them from leafy greens.
Huh.
So do you need to eat dairy to get enough calcium for healthy bones?
Well, how does a gorilla get dairy?
Here's Catherine Milton again.
Because many wild plants have very high concentrations of calcium
and they're able to get all of the calcium that they require
from their wild plant diets.
So you might be able to keep your bones strong on a diet without dairy
if you track what you're eating.
Another potential issue with the paleo diet is
how much meat you're eating.
Here's Daryl Edwards.
So I'll definitely always have some animal protein on a daily basis.
And in terms of the amount, it might be 100 grams of steak.
It's not excessive amounts of meat or fish.
It might not be excessive, but according to the most recent guidelines
from the National Health and Medical Research Council of Australia,
that's still too much meat.
These days, they're recommending about 65 grams of red meat per day maximum.
or, instead, 100 grams of fish.
That's about one medium-sized meatball.
And what happens if you go overboard?
The strongest evidence is a relationship between red meat
and increased risk of colorectal cancer.
That's Jonathan Hallett,
from the collaboration for evidence research
and impact in public health at Curtin University in Perth.
But also links with lung and renal cancer
and potentially pancreatic cancers.
Jonathan says that the potential overconsumption of meat
is particularly troubling,
given that the paleo diet says you're not allowed to have processed grains,
including whole wheat bread.
Whole grains in particular are packaged with bran and fibre,
and we know that there's evidence for that around preventing the formation of small blood clots.
It helps lower cholesterol, moves waste through the digestive tract.
So if you're both consuming large amounts of, say, red meat,
which we know has a link to colorectal cancer,
and then you're not consuming whole grains,
which we know is linked to preventing cholera.
rectal cancer, you know, what is that actually going to do?
Well, apparently, increase your risk of colorectal cancer.
Our final question on the paleo diet is about these so-called anti-nutrients.
Now, these are often found in plants as a defence against predators.
And according to Daryl...
Avoid anti-nutrients where possible.
And this is why you shouldn't eat potatoes, legumes and wheat, because they're chock full of
these anti-nutrients.
He says that in the worst case, it can kill you, but more likely,
You might incur some slight sickness, or you may have suffer illness over a longer period of time.
But there's no human studies that have demonstrated that well,
and the founder of the paleo movement, Dr Lauren Cordane, even admits that on his website.
Plus, anti-nutrients aren't necessarily anti-your health.
Dora Maranova, who's a professor at Curtin University in Perth and works with Jonathan Hallett,
told me via email that, quote,
In the scientific literature, there have been calls for more than a decade to stop the use of the term anti-nutrients, or change it, because of the benefits these substances have.
The term is misleading, end quote.
So some of these anti-nutrients, for example, have been found to have antioxidant and anti-cancer qualities.
Even in the paleo-loving world, this issue legumes large.
Chris Cressor, who's the author of Your Personal Paleo Code, for example,
reckons it's okay to eat legumes.
Okay, so when it comes to science versus the paleo diet,
does it stack up?
Well, although the diet isn't paleo
and it's littered with these frustrating pseudosciencey words
or science words used badly,
it's understandable that people are moving towards these sorts of diets,
particularly when conventional medicine isn't giving them
satisfying responses. So take our paleo advocate Darrell Edwards, for example. Now he found the
paleo way of life because he was in really bad shape. He'd pretty much eaten chocolate bars and
microwave spaghetti for a decade and then just found he was in really poor health. So I was an
elevated risk of heart disease. I was pre-diabetic and the doctor's remedy for that was for me to
undergo a medication program which is going to be for the rest of my life. So instead of going on the
meds, he searched for a different lifestyle and found the paleo diet, and now he says he's very
healthy and no longer pre-diabetic. But based on the science, he probably didn't need to go
paleo. So, the message for today? Don't say you're on the paleo diet. Sure. Reduce your
consumption of processed foods and excess sugars. But when it comes to science versus paleo,
it's science one. Paleo diets.
There you go.
Season one, episode one of Science Verses,
it was published in May 28th, 2015.
We hope you had fun on this trip down memory lane.
We really did.
I'm going to say it one more time.
Thank you so much for listening to the show.
We would not be here without you.
And so finally, we're going to play you out with perhaps
one of our greatest podcasting achievements.
Is it the awards we've won?
No.
Is it the scientific papers we've published?
No.
It's from an episode we made several years back on sharks.
And in this episode, we talked about how sharks have gotten a lot of bad press.
And they really need a glow up.
This scientist we talked to, Dr. Chris Pepper Neff, had just the ticket for how we were going to do this.
Sharks have been demonized. And when I do my musical, Flaws the Musical, it's going to be, you know, like wicked. It's going to be like wicked. And the shark is going to be the star of the musical. And the shark starts singing, you know, defying gravity. And whatever it is. Do you have any songs ready to go?
Oh, I'm working on them.
I've already bought Flawsthemusical.com.
Rose?
Yeah.
Should we help him out a little?
I think so.
I know you people are scared of me.
But I'm not the one to blame.
You saw jaws as a child.
And now you think I may
But I need to eat sometimes
And even if you're on the beach
I'll choose a seal for food
Row back my eyes
And breathe
Or I might try to bite a manatee
But human flesh
It's just not my cup of tea
So I won't pull you down
Sharky
I find that hard to believe
Dolphinda, haven't you been listening to anything?
You really don't want to eat humans
No
I just want to buy
Tamadity
Or maybe a seal of
But human flesh
It's really just not what I'm into
So I won't pull you down.
That's Science versus Sharks.
All right, so we're back to our...

Wendy, you and the team have been so, so joyous in your creation and explanation of science.
And I can't wait for the next 10 years.
Thanks for giving me a toothbrushing existential crisis.
morning and happy 10 years. Thanks for making this place we call world a little bit more
informed and thus a better place. Thank you. Goodbye. Adios. I'm Wendy Zuckerman. Back to you next
time.
