Hello and welcome to Wee.
Wow on the Weekend.
I'm your host, Dennis.
That's my co-host, Reggie, the giant pigeon.
This is the show where we talk, and gab, and chit-chat, and jibber-jabber.
Oh yeah, and we chin-wag, that's for sure.
Yep, that's us, just blabbering away all the live long day.
Just blabbering.
Yackety-yackin'.
All the time.
Oh no, we never run out of stuff to say.
No siree.
Me plus Reggie equals sparkling conversation.
That's what I always say.
Right, Reggie?
Right.
Well, that's enough chit-chat.
What do you say we get on to our first segment?
Okay, let's do the Q&A segment.
The Q&A segment.
This is the segment where we answer questions that fans write to us on Spotify.
The first question we have is from Ella.
It says, Dennis, what do you think of Mindy and Guy going on adventures without you?
And hi, Reggie.
Huh, what do I think of Mindy and Guy going on adventures without me.
You know what?
I think it's totally fine.
Yeah, really.
It doesn't bother me at all.
Seriously, it never even crosses my mind how much fun they're having doing stuff like going to Antarctica or up into space or back in time.
Yep, I'm totally, totally good with it.
Okay, you got me.
I want to go on adventures too.
Mindy and Guy Raz, if you're listening to this, take me on your adventures.
I promise I'll be really quiet and nice and I won't complain too much or ask if we have snacks.
Just take me on your adventures.
Okay, this next one comes from Ryan who asks, how big is the universe?
Well, Ryan, the universe is really, really, really, really, really, really.
Wait, how many reallys was that?
Oh, thanks.
Really, really, really, really, really big.
Hope that helps.
Next question.
This next question comes from Elizabeth who asks, what is the best flavor of ice cream?
Oh, that's easy, Elizabeth.
The best flavor is chocolate.
No, wait, vanilla.
No, wait. chip.
No, wait.
Actually, it's strawberry or strawberry cheesecake or strawberry shortcake.
I can't decide.
Reggie, what do you think?
Oh, yeah.
Cookie dough.
Maybe cookie dough is the best.
No, wait.
Cookies and cream.
I forgot about Rocky Road.
Oh, no.
What are we going to do?
Okay.
How about this?
I would take every flavor of ice cream and melt them and mix them into ice cream soup.
Because Reggie, soup is the best flavor of ice cream.
Next question.
Okay, this last question comes from Haley and Ben.
It says, dear Dennis.
Ooh, so formal.
I love it.
Dear Dennis, where do you live and do you live with Reggie?
Well, Haley and Ben, I live with my mother, and Reggie lives in Mindy's Gingerbread Mansion.
And Reggie comes over here so we can record the podcast.
But Reggie never invites me over to Mindy's.
So Actually Reggie, why don't you ever invite me over?
What?
I am not a bad guest.
I refuse to leave because I'm having so much fun and because I want to have sleepovers.
What do you mean you can never sleep when I sleep over?
Reggie, I have to repeatedly yell sleepover.
Until the sun comes up, so you know that it's a sleepover.
What?
And you hate it when I turn all the ice cream into ice cream soup?
Everybody knows it's the best flavor.
Oh, whatever.
Thanks for all your questions, listeners.
Keep them coming.
If you write me a question on Apple Podcasts or Spotify, I just might read it on WeWow on the weekend.
Okay, now it's time for the next segment, Inside Tinkercast Studios.
Inside Tinkercast Studios.
This is the part where we revisit an episode of one of my favorite Tinkercast shows.
And today we're listening to Wow in the World, Season 2, Episode 8, called A Dog's Nose Always Knows.
In this episode, Mindy is dog-sitting her Aunt Mojo's dog, Niels.
Wait.
Neil's his Aunt Mojo's dog?
Well, then who's Beardsley?
Oh, right, that's Guy Raz's friend's dog.
Hey, Reggie, do you think I should get a dog?
Yeah, you're right.
I should get two dogs.
I'd name them Skittles and something to do with snooping.
Um, Snoop Dogg.
Oh, that's already someone's name?
Then how about Scout?
Skittles and Scout.
So cute.
Oh, yeah.
We got to play the episode.
OK.
Here we go.
And play.
Wee Wow will be right back.

Now back to the show.
Oh, man.
Well, good thing you're so adorable.
Yes, you are.
Yes, you are.
Who's an adorable little bulldozer of destruction?
You are.
Yes, you are.
Oh, Kairos is here.
Come on in.
Mindy.
Mindy, are you okay?
I could have sworn I heard some zoom.
No, no, no, no, no, no, no.
Come back here.
You can come back here right now.
Oh, sorry, Guy Raz.
Mindy, this dog is slobbering all over me.
Sorry, Guy Raz.
I'm babysitting my Aunt Mojo's dog for the weekend.
Get down, boy.
Don't worry about it, Mindy.
Nothing a bathtub full of hand sanitizer can't fix.
What are you...
Much better.
This sure is one big dog you have here, Mindy.
I know, right?
He's a great Dane.
Wow, so not just a big dog, but the biggest dog.
Yep, biggest dog breed in the whole world.
By the way, what's the big guy's name?
Oh, his name is Neals.
Oh, I get it.
You get what?
Neals, like he kneels, like a dog.
What?
No, Neals as in Neal's breed.
Uh, Niels Bohr, Niels Bohr.
Niels Bohr, Guy Raz.
He's the scientist who basically invented the field of quantum physics.
Oh, yeah, Niels Bohr.
Didn't he win the Nobel Prize in 1922?
Sure did.
And you want to know another fun fact about him?
What?
He was Danish.
Oh, that's starting to make sense.
He was Danish.
Danish.
His name was Niels.
He was a great scientist.
And Danish people are called Danes.
And so Niels is a great Dane.
Wow, that is very clever, your old Dan mojo.
Right?
Yeah.
So what were you doing that got old Niels so riled up?
Oh, so he was helping me to solve a mystery.
A mystery?
Yep.
In fact, it's what he does for his day job.
He solves mysteries.
Mindy, are you sure you're not just confusing him with Scooby-Doo?
No, I'm not confusing him with Scooby-Doo, Guy Raz.
But like Scooby-Doo, Neils is a Great Dane, and both Scooby and Neils are working dogs.
Working dogs?
Yep.
A working dog is a dog that's not just kept for a pet, but also trained to perform a certain job.
And don't worry, Guy Raz.
I already looked over his resume, and he is more than qualified to be on the case.
So, Niels, this job here requires you to perform a lot of different tasks.
You think you'd be able to handle a workload like that?
Nice, confidence.
I like that.
Now, what would you say is your biggest weakness, professionally speaking?
Well, I appreciate the honesty.
Now, finally, it says here that you've had three years of improv experience.
Could you elaborate on that a little for me?
You see, Guy Raz, dogs like Niels have been helping us humans out for centuries.
It's part of the reason why we get along so well.
Isn't that right, pal?
And you know what?
I'm pretty sure I have a book on this in the library.
Come on, Guy Raz, follow me.
Of course you can come too.
All right, here we are.
Wow, Mindy, I had no idea you had this whole library back here.
Yeah, it used to be Reggie's Taekwondo dojo, but ever since he moved to the time machine I've been slowly filling it up with all of my books and brains and bubble gum.
Brains?
Uh, bubble gum?
Oh yeah.
So when I built this gingerbread mansion to organize all of my stuff in alphabetical order by room only, i never got past the bees.
The rest of the house is a disaster obviously, anywho.
Now what was i looking for?
Let's see here um, the weird and wacky world of worms?
No, that's not.
It working weasels of wisconsin?
No oh, here we are.
Working dogs of the world.
Now I just need to find this one chapter.
Oh, found it.
Okay, Guy Raz.
It says right here that Dogs have been working alongside humans for thousands of years, with evidence of them being used on farms in ancient Viking times.
And you know now that I think about it, Mindy I've seen working dogs used for lots of different jobs, from security at airports to finding people that are lost in the forest, to even detecting diseases like cancer.
Uh, hold the phone, Guy Raz.
Detecting cancer?
Well Mindy, it turns out that some dogs are so good at smelling things that some scientists are using their incredible sense of smell to detect diseases like cancer, cancer and even diabetes.
That's bonker balls.
They must be packing one impressive snozz if they're able to detect something like that.
Especially because to us humans, those diseases don't smell like anything.
And if dogs can smell them early enough, it might be easier for doctors to start to heal people who might have those diseases.
So how do Do dogs smell something like that?
Well, Mindy, when we look at the numbers, it's not really that surprising.
Because dogs have 25 times more olfactory receptors than we humans.
Oh, olfactory receptors.
Aren't those those things in our nose that help us to detect smells?
Exactly.
And you can't see them.
But because of these extra receptors...
Dogs have a smelling ability that's about 100,000 times greater than our own.
That's bonker balls.
Now Mindy, we humans, we're very visual creatures and we learn about the world mainly through what we see through our eyes.
And because of this, the human brain is largely taken up by the visual cortex.
The visual cortex being the part of our brain that figures out what we're seeing with our eyes.
Exactly.
And we also have a part of the brain called the olfactory cortex which is responsible for analyzing what we smell.
Okay, so how does a dog's olfactory cortex compare to ours as humans?
A dog's olfactory cortex is 40 times bigger than ours.
So let me get this straight, Guy Raz.
Not only are these super sniffing canines able to detect more smells than us humans, but because of their overblown olfactory cortex, they're able to figure out what that smell is better than us too.
That's right.
Okay, so Neal's here may have a pretty great sense of smell...
But how are these medical detection dogs able to sniff out diseases like cancer?
Well, researchers from the Pierre and Marie Curie University in Paris France, have suggested that cancerous cells, which are the cells that mutate or change to become cancer well, those cells release different chemicals than healthy cells.
And so these dogs are able to smell the chemicals that these cancerous cells are giving off?
They can basically smell cancer?
That's right.
Remember, Mindy, these dog noses are highly sensitive.
Wow, it's like a real-life superpower or something.
Get away from the superpower!
It really is, Mindy.
And some studies have confirmed that trained medical detection dogs can even detect skin cancers by just sniffing the skin.
Or cancer in human lungs by sniffing human breath.
Wow, that is really impressive, Guy Raz.
I had no idea that dogs were using their super sniffing abilities in so many important ways.
I mean, I always just thought they were using their noses to sniff each other's...
So, by the way, what exactly is Niels here helping you out with?
You said he was a detection dog, too.
Oh, yeah, the mystery he was helping me solve.
Okay, so, um, well, bed bugs.
Bed bugs?
Yep.
It's a specialty.
I've just been itching all over the place for the last couple of weeks and I'm afraid there might be an outbreak of them.
Shh, shh, shh.
So Niels here is able to detect where the bugs are in your house.
The same way those medical detection dogs are able to detect certain diseases.
Oh yeah, but it goes even deeper than that.
So not only is Niels able to detect the smell of bed bugs in the house, but he's able to pinpoint the exact location where the smell is coming from.
And he does this using a very special ability called... stereoscopic sniffing.
Stereoscopic sniffing?
Is that like stereoscopic vision?
Well, sort of.
So stereoscopic vision is what we humans use to predict depth.
That's right.
And the way our vision works is each of our eyes sees the same thing in a slightly different way.
So, for example, I'm looking at Niels here, right?
And one of my eyes is seeing him, and...
My other eye is also seeing him.
And those two images combine in my brain to create one single image of Niels.
Otherwise, I'd be seeing two of him all the time.
And that's how our brain knows how far away we are from the things we see.
Stereoscopic vision.
Wow, that's so cool.
Hey, now I want to imagine what my life would be like without Niels. stereoscopic vision.
Here goes.
Easy, Mindy.
If you keep crossing your eyes, you're going to lose your balance and fall.
Do you need a hand?
No, I'm okay.
My eyes just got all googly when I tried using my stereoscopic vision to look at my nose up close.
Anywho, back to stereoscopic sniffing.
Gairaz, did you know that dogs are able to smell separately with each nostril?
So, They see the world with their noses?
Kind of like the same way we see the world with our eyes?
Exactoritos, Guy Raz.
Huh.
I wonder what this room smells like to Niels.
Well, I think it would probably smell like 2.30 in the afternoon.
Oh, sorry.
2.34.
2.34?
What are you talking about, Mindy?
Oh, well, that's sort of the other reason I'm dog-sitting for Niels here.
See, my wall clock finally ran out of juice.
I did notice that it had stopped ticking.
Yeah, and I haven't had any time to get down to the store to get some more OJ for it.
So what does that have to do with looking after your Aunt Mojo's dog?
Well, without a clock to tell me what time it is, I'm having to rely on Neal's.
Which, by the way, did I tell you that dogs can tell time through smell, too?
Okay, Mindy, I know I can be pretty gullible.
Like, remember the time you told me that planting Cheerios can grow a donut tree?
Well, that wasn't completely untrue.
Uh, yeah, I'm pretty sure it was.
Okay, Guy Raz, here's how you grow a donut.
First you take the Cheerio and you place it in the ground, cover it up with a little bit of dirt, sprinkling of water and let the sun shine in.
Wow.
Are you sure this is gonna work, Mindy?
Of course I'm not sure, Guy Raz.
But if I'm right, We'll have grown fresh donuts just in time for breakfast tomorrow.
Yeah, I'm pretty sure that wasn't true, Mindy.
Well, this time I'm telling the truth, Guy Raz.
According to Professor Alexandra Horowitz from the Dog Cognition Lab at Barnard College in New York, dogs can track and analyze how scents in a room change throughout the day.
And this allows them to know what time of day it is?
Exactoritos.
According to Professor Horowitz, throughout the day, hot air will rise, usually along the walls of a room, and then travel to the center of the room and then drop.
And so dogs are able to track the smells in all of that air?
You got it.
And by tracking those smells, dogs are able to tell whether it's morning, afternoon, or night.
Huh.
Well, that might also explain why a lot of dogs are able to predict when their owners are going to come home.
Oh, yeah.
Since I've been dog-sitting Niels.
He's always waiting for me at the door when I come back from my trombone lessons.
Now, let me just smooch that little doggy face of yours.
Say, Mindy, it looks like Neil's here might be getting a bit worked up.
Maybe we should take him for a walk.
Oh, okay.
But, Guy Raz, weren't you planning to do a second fermentation on your kombucha this afternoon?
Well, yeah, but you know what, Mindy?
Oh, boy!
I think I can wait.
Yeah, I think it's probably a good idea for both Niels and I to get our ya-ya's out.
Watch out, Guy Raz!
Man, I just finished rebaking that gingerbread door.
All right, Guy Raz, come on.
We should probably go catch up.
After you, Mindy.
What a beautiful day for a walk outside to chase the dog I'm supposed to be taking care of.
It sure is, Mindy.
Though I don't like the look of those clouds over there.
Do you think we should have brought an umbrella?
Nah, we'll be fine, Guy Raz.
Okay, if you're sure.
Hey, Nils!
Nils, where'd you go, little buddy?
There you are, you little scamp.
Can't go running off like that.
You know, I thought you were pulling my leg, Mindy, but Neil's was completely right.
It is just after 2.30 in the afternoon.
I told you he could smell the time of day.
But, Guy Ross, if you think that's impressive, you should know that dogs can also smell the future.
The future?
Yep.
They can smell it on the breeze.
Dogs can smell the future on the breeze?
Sure can.
Remember how I told you that dogs can see the world with their nose the same way that we see the world with our eyes.
Yeah.
Well, according to Professor Alexandra Horowitz, the scents that dogs use to build their picture of the world are often carried on breezes.
So what's happening around that corner over there might have already wafted over this way, meaning that Niels knows what's around the bend before we've even gotten there.
Wow. are often said to be able to detect oncoming storms, they can actually smell it coming?
You know it, Guy Raz.
So when a storm is coming in, the ground kind of loosens up a little bit, throwing all kinds of smells into the air.
These smells then evaporate into the air and the dogs can pick up on them as they travel on the wind.
Wow.
Oh, what is it, boy?
What's he saying, Mindy?
Wait, he's saying...
Hey, where is he going off to now?
Looks like he's going up to that fire hydrant and... Ugh.
Come on, buddy, we're almost home.
Couldn't you hold it?
Well, I guess he's just marking his territory.
Actually, Guy Raz, that might not be true.
What?
So here's the thing.
Even though wolves and other wild dogs dolphinately do pee on stuff to mark their territory, some scientists think that domestic dogs, or the kind of dogs that live with us, pee on things for a very different reason.
And what's that?
Well, that same researcher from the Dog Cognition Lab, Professor Horowitz.
She describes it as a type of calling card.
You mean like putting an ad up on a bulletin board?
Exactly.
So here's the deal, Guy Raz.
Using their supersonic sniffing noses, dogs are actually able to tell a lot about each other, and they do this by sniffing each other's pee.
I'm not making this up.
They're able to tell how old the other dog is, whether it's a male dog or a female dog.
They're even able to tell what it had to eat earlier that day.
It's crazy.
Let's see here.
Golden retriever, two years old, 14 in dog years.
Name is Frank.
Dinner was steak tartare.
Fancy.
Go visit Frank.
Ah, Mindy, I told you we should have brought an umbrella.
Hurry up, Guy Raz.
Get inside before you get all wet.
Coming, Mindy.
I just remembered I've got all my laundry hanging outside on the clothesline.
I've got to go get it before it rains.
Rent, rent, rent, rent, rent, rent, rent, rent, rent, rent, rent.
Closed one.
Look at it outside.
Mindy, what on earth is that on your laundry pile?
What, these?
Uh... Oh, these are my new pajama overalls.
Grandma G-Force knitted them for me last week out of 100% yak wool.
What?
Sleep in them every night.
Last week, you say?
Last week, I say.
Mindy, I don't think you have bed bugs.
What do you mean?
Niels, bring your nose over here.
Do I have bed bugs?
No?
No?
I think you've been itchy all this week because of these new pajamas.
Oh, 100% yak wool.
That explains why Niels didn't find any bed bugs.
Hey, Niels, what's the time right now?
Yep, I agree.
What did he say?
He said it's time for you to get a new pair of pajamas.
Well, I guess I can't argue with that.
Niels really knows...
I'm pointing to my nose.
Yeah, yeah, yeah, I get it, I get it.
Niels really knows his stuff.
Wow, that was so cool.
I can't believe...
Dogs can basically smell the future.
We should go find a canine fortune teller.
I have so many questions like, will WeWow on the weekend ever win an Oscar?
Or will I ever get the rarest Nokiman card, Farfellizard?
Or will Guy and Mindy RSVP to my annual bring your own burgers and hot dogs and coleslaw and desserts barbecue?
Reggie, what do you mean no?
You don't know that.
You don't even have a nose.
Oh, whatever.
Let's just wrap up the show.
Thanks to all you listeners out there for tuning in to Wee Wow on the weekend.
If you have a question for me, call and leave me a message at 1-888-7-WOW-WOW.
That's 1-888-7-WOW-WOW.
I just might answer your question on Wee Wow on the weekend.
Okay, should we do the goodbye song?
Great.
That's the end.
But I'll do another show tomorrow.
But for now, that's the end of the show.
Bye.
