Latest / Stuff You Should Know / SYSK Selects: How Pollen Works
Transcript
- 0:01Speaker 1: Hello, everyone, It's Saturday, and it's Chuck, and that means
- 0:04Speaker 1: it's time for another Stuff you Should Know. Select we
- 0:07Speaker 1: go all the way back to July to two to
- 0:11Speaker 1: discuss pollen. I'm not sure when this is gonna come out,
- 0:14Speaker 1: but if I'm timing it right, it should be sometime
- 0:17Speaker 1: during pollen season. And that's why I picked it, because
- 0:20Speaker 1: understanding the enemy is the first step toward defeating it.
- 0:24Speaker 1: And so many people have bad problems with allergies and pollen,
- 0:28Speaker 1: and UH, to understand how that really works in your body,
- 0:30Speaker 1: it's kind of cool and it really helps. So I
- 0:33Speaker 1: hope you don't have any problems with pollen. I hope
- 0:34Speaker 1: you're doing okay, but learn all about how pollen works
- 0:37Speaker 1: right here, right now. Welcome to Stuff you Should Know
- 0:42Speaker 1: Fromhouse Stuff Works dot com. Hey, and welcome to the podcast.
- 0:51Speaker 1: I'm Josh Clark and there's Charles W. Chuck Bryant, and
- 0:54Speaker 1: that means it's time for Stuff you Should Know. But
- 0:56Speaker 1: itchy screezy skiez scratchy addition, not scheezy. No, that's not
- 1:03Speaker 1: itchy scratchy sneezy edition. That's what I meant. There you go.
- 1:07Speaker 1: It's funny how you can mix words together come up
- 1:09Speaker 1: with other words. You didn't mean to say, Jerry's eyes
- 1:13Speaker 1: are at Itchen, Yeah, well we should say. We were
- 1:16Speaker 1: just talking about the pollen count here in Atlanta. That's
- 1:18Speaker 1: pretty much all we ever talked about. Ever when the
- 1:21Speaker 1: cameras not on or the mics aren't recording that in
- 1:23Speaker 1: Coca Cola. Oh you know how everyone comes to Atlanta
- 1:28Speaker 1: and they're like, oh, every street's named peach Tree. Let's
- 1:30Speaker 1: go drink a coke because so it's the only two
- 1:32Speaker 1: things we've ever had. Alright, sorry, that's fine. So you
- 1:37Speaker 1: want to talk about Pollentin Moore, Yeah, it's low right
- 1:39Speaker 1: now in Atlanta. Thirty nine that's moderate, Yeah, well low
- 1:43Speaker 1: for us, right, but like according to the pollen scale
- 1:46Speaker 1: they scale that they used to count pollen and then
- 1:49Speaker 1: designated somewhere along the pollen spectrum, thirty nine is considered moderate,
- 1:53Speaker 1: not even low moderate. When it's really bad here in Georgia,
- 1:58Speaker 1: it gets to about nine thousand. Those are the few
- 2:02Speaker 1: weeks that the the streets run yellow with when it
- 2:06Speaker 1: rains with yellow water. Yeah, it looks like p yep.
- 2:10Speaker 1: Your car is totally covered in it. You're covered in it.
- 2:12Speaker 1: It's just everywhere, everywhere. Yeah, but now we're about to
- 2:16Speaker 1: tell everybody we're basically going to turn everybody into a palenologist. Yeah,
- 2:20Speaker 1: to an extent, should be a big fan after this
- 2:22Speaker 1: an amateur palenologists. I think about a third of all
- 2:26Speaker 1: the plants and vegetables and fruits and vegetables we eat
- 2:30Speaker 1: are you know here thanks to pollen. So if you
- 2:32Speaker 1: like eating food doesn't come in a box, thank you pollen.
- 2:37Speaker 1: Is it just a third that pollinate or a third
- 2:40Speaker 1: that are just angiosperms or gymnosperms, a third that that pollinate? Wow,
- 2:45Speaker 1: what's up with the other two thirds? I don't know. Well,
- 2:48Speaker 1: you know, bananas, they are clones of one another. There
- 2:52Speaker 1: you go, there's like there's there's some one. There's like
- 2:55Speaker 1: I think a thousand varieties of bananas. And thanks by
- 2:58Speaker 1: the way to Dama interesting for this information him. But
- 3:01Speaker 1: there's like a thousand varieties or species of bananas, but
- 3:04Speaker 1: each one like if you eat like a type of
- 3:06Speaker 1: just one of those species of bananas, you're eating an
- 3:09Speaker 1: exact clone of every other banana in that species. Because
- 3:13Speaker 1: many thousands of years ago, humans just stumbled upon the banana,
- 3:17Speaker 1: which is the hybrid of two basically inedible fruits that
- 3:22Speaker 1: came together to form the delicious banana, but made um sterile.
- 3:26Speaker 1: All banana plants are sterile, and the only way that
- 3:28Speaker 1: they're allowed to propagate is by human hand. Theous I
- 3:32Speaker 1: did a don't be dumb about that? Yeah, well you
- 3:35Speaker 1: just did it again. Yeah, you can check out Don't
- 3:37Speaker 1: be dumbs on our website Stuff you should know dot com. Wow.
- 3:41Speaker 1: All right, anyway, Pollen, Yes, it's been around for a while. Um.
- 3:44Speaker 1: I know in our b podcast we talked about how
- 3:46Speaker 1: bees and and paulling kind of emerged side by side
- 3:49Speaker 1: a hundred million years ago, but pollen actually goes further
- 3:55Speaker 1: back than that. In this article, it says about three
- 3:57Speaker 1: seventy five million years ago is when the plants started
- 4:01Speaker 1: getting clever and spreading their seed literally using pollen different techniques.
- 4:07Speaker 1: And I think that, um, the gymnot sperms were first,
- 4:10Speaker 1: you think so, I believe so. Uh yeah, And the
- 4:13Speaker 1: author of the article here points out that the reason
- 4:16Speaker 1: why it evolved was so plants didn't have to be
- 4:20Speaker 1: dumb and rely on water to carry their junk to
- 4:24Speaker 1: fertilize other junk. You know, they're like, how about wind
- 4:27Speaker 1: or how about that bat? Or about that beetle? Yeah,
- 4:30Speaker 1: or how about that bird pooping it out? That's right? Yeah? Um,
- 4:35Speaker 1: And like I said, I think pollen grains or plants
- 4:39Speaker 1: spread their seed. Literally, plant pollen is what amounts to
- 4:43Speaker 1: plant sperm. Yeah, it's like I always go to the
- 4:47Speaker 1: kids science pages to research. First off, I mean they're good,
- 4:51Speaker 1: they're they're colorful. Uh yeah, if we want to pollination
- 4:54Speaker 1: very simply, you know, people reproduce. Animals reproduce. They need
- 4:58Speaker 1: male and female parts. Plants and flower you are no different.
- 5:01Speaker 1: They need male parts to connect with the female parts
- 5:05Speaker 1: to make an egg. And in this case, pollination is
- 5:07Speaker 1: how it's done. So basically, how that sperm the pollen
- 5:10Speaker 1: reaches that egg, which is the ovule, right, and once
- 5:14Speaker 1: they get together, magic happens. That's right. But let's talk
- 5:17Speaker 1: about the way it looks first of all. Yeah, there's
- 5:20Speaker 1: like there's a lot of different looks to pollen depending
- 5:23Speaker 1: on the plant um and all of these variations. What
- 5:28Speaker 1: it can be like a cone literally a pine cone. Yeah,
- 5:32Speaker 1: and look at you know, just look up microscope pollen
- 5:34Speaker 1: on Google images and you'll see all sorts of weird,
- 5:37Speaker 1: colorful shapes and sizes. Yeah. Some look like blowfish. Yeah,
- 5:41Speaker 1: others look like sputnick really yeah, I didn't see the spot.
- 5:45Speaker 1: Some have ribbed edges for and all of these adaptations
- 5:52Speaker 1: are um or mutations. I guess they became adaptations allow
- 5:56Speaker 1: that pollen to kind of better ensure that it's going
- 5:59Speaker 1: to be carried to where it needs to go. Yeah,
- 6:02Speaker 1: it's it has a purpose. It's not just like, hey,
- 6:04Speaker 1: this one would look neat if it looks like a
- 6:06Speaker 1: starfish exactly. In the end. Some have wings kind of
- 6:10Speaker 1: what amount of basically wings because they're carried on the wind.
- 6:15Speaker 1: Oh yeah, yeah, like dandelion paulin, it's carried on the wind.
- 6:19Speaker 1: True will dandelions self palling night too. We'll get to
- 6:22Speaker 1: that though. Yeah. They're slippery little guys. Yeah they are.
- 6:25Speaker 1: They're also high and phytonutrients as well. Dandelion greens are
- 6:31Speaker 1: of the stems, No, the leaves, oh, the little leaves,
- 6:37Speaker 1: the yellow part. So here here's the rule of thumb.
- 6:39Speaker 1: There's a New York Times article that came out very
- 6:42Speaker 1: recently about phyto nutrients and how we basically bred them
- 6:44Speaker 1: out of our food and um. The rule of thumb
- 6:48Speaker 1: is the the bitter, the bitterer or more bitter the plant,
- 6:53Speaker 1: the higher it is in phytoonutrients. Phyto nutrients have kind
- 6:56Speaker 1: of the bitterest, stringent taste, and we tend to don't
- 7:00Speaker 1: really like that, so we stopped eating those things over time,
- 7:02Speaker 1: replace them with sweet things that aren't necessarily good for us,
- 7:06Speaker 1: like you know, potatoes and other starches. Yeah, well, bitter
- 7:10Speaker 1: things can also kill you, that's probably why. So you know,
- 7:13Speaker 1: that's that's a pretty good point. But bitter stuff that
- 7:16Speaker 1: you know won't kill you. Dandelion leaves God and needs
- 7:20Speaker 1: them right now. But back in the day, I bet
- 7:22Speaker 1: people are like that tastes bad and it killed tuk tuk,
- 7:25Speaker 1: So let's just not eat it right exactly alright, So
- 7:29Speaker 1: should we talk about pollination. Talked a little bit about pollen.
- 7:34Speaker 1: Now we need to talk about how plants make little
- 7:36Speaker 1: baby plants, right, And it's it's pretty simple, Like I said,
- 7:39Speaker 1: the male part and have you uh, It really helps
- 7:43Speaker 1: to follow along if you go to a handy dandy
- 7:46Speaker 1: little visual aid I found, because they really break down
- 7:50Speaker 1: the male parts and the female parts. The female is
- 7:53Speaker 1: the has the pistol and that's p I S T
- 7:56Speaker 1: I l and within that you have the over, which
- 8:00Speaker 1: you know sits down low in the plant, and the style,
- 8:03Speaker 1: which is a long, ah thin h appendage. I guess
- 8:09Speaker 1: that contains pollen tubes. And then at the top you
- 8:12Speaker 1: have your stigma, which is going to catch the pollen. Yeah,
- 8:14Speaker 1: and that's the female part, right, that's the lady. Don't
- 8:17Speaker 1: be confused because it is phallic in nature. Yeah, true,
- 8:21Speaker 1: but it's still the female part. And the male has
- 8:23Speaker 1: to filament, which is a long stem, and then the
- 8:25Speaker 1: anther at the top which holds all the pollen. And
- 8:29Speaker 1: that's pretty much the long and short of the parts.
- 8:32Speaker 1: And is that just angiosperms that you're describing or is
- 8:35Speaker 1: that all all pollinating? I think these are just the angiosperms. Well,
- 8:39Speaker 1: we should say quite explicitly that there's basically two ways
- 8:42Speaker 1: that plants compollinate. There's gymnas sperms and angiosperms. And the
- 8:46Speaker 1: big difference between the two is that gymnasperms literally that
- 8:51Speaker 1: means naked seed, which, by the way, gymnasium is means
- 8:55Speaker 1: place to be naked canasium and German did you know that, Yeah,
- 8:59Speaker 1: this so gymnasperms naked seed. There's nothing protecting the seed
- 9:03Speaker 1: once it's once it's produced, and a seed is just
- 9:06Speaker 1: a germ, a fertilized ovum or ovule, right yeah, um,
- 9:10Speaker 1: and just sperms produce something to protect that seed, whether
- 9:13Speaker 1: it's a shell like a nut or fruit like an
- 9:17Speaker 1: apple with the seeds inside, right, because an apple is
- 9:19Speaker 1: just a an enlarged ovule ovary and the seeds are
- 9:25Speaker 1: the fertilized though. Yes, Well, you can also pollinate, across
- 9:29Speaker 1: pollinate or self pollinate, right, those are the other two differences.
- 9:33Speaker 1: So you were saying, what what dandelions self pollinate, Well,
- 9:37Speaker 1: they can do both, um, But they do have a
- 9:39Speaker 1: little a cool little feature. They basically grow up. You know,
- 9:42Speaker 1: this is when there's still the little yellow flower. They
- 9:45Speaker 1: have these little florets that grow up and if you look,
- 9:48Speaker 1: well you probably can't see if you look really really close.
- 9:50Speaker 1: So these little florets that grow up, and as it grows,
- 9:54Speaker 1: it carries uh the pollen on its little stem and
- 9:58Speaker 1: then eventually gets to a point where it doesn't start
- 10:01Speaker 1: grow growing up anymore, and it splits and then starts
- 10:04Speaker 1: curling back on itself to uh, you know, no way.
- 10:11Speaker 1: It picks up its own pollen from its own style.
- 10:13Speaker 1: But it's self pollination. It's not gross or like perverted.
- 10:16Speaker 1: There's a there's a lot of them. There's a lot
- 10:20Speaker 1: of plants out there, though, that have mechanisms to prevent
- 10:24Speaker 1: them from self pollinating. It couldn't can't be good or bad.
- 10:27Speaker 1: That's what I couldn't figure out. Well, the plants somewhere
- 10:29Speaker 1: along the way figured out like, hey, the wider the
- 10:31Speaker 1: gene pool, the better off we are, because the more
- 10:34Speaker 1: room there is for adaptation, mutations and than adaptations. Right. Yeah,
- 10:38Speaker 1: But in here the author said ideally it cross pollinates,
- 10:42Speaker 1: But I don't think that's the case always. Well, it's
- 10:45Speaker 1: not ideal, it's just some doing some don't write. I mean,
- 10:47Speaker 1: if you look at it like from just an animalistic
- 10:51Speaker 1: or an organism viewpoint, right, like with us, if you
- 10:56Speaker 1: just get a bunch of Mennonites together and they just
- 10:59Speaker 1: reproduce with one other, there's going to be defects that
- 11:02Speaker 1: just are propagated throughout this this little gene pool. But
- 11:05Speaker 1: if the Mennonites spread out into the you know, larger
- 11:08Speaker 1: country as a whole, those defects are going to you know,
- 11:14Speaker 1: I guess be kind of watered down by the size
- 11:16Speaker 1: of the gene pool. I think it's the same thing
- 11:18Speaker 1: with self pollinating and cross pollinating. Yeah, because it's interesting
- 11:22Speaker 1: because things like peanuts or self pollinators and that's why
- 11:25Speaker 1: they thrive. But corn has a mechanism to not allow
- 11:30Speaker 1: itself to self pollinate. Like there, I think the sperm
- 11:35Speaker 1: is ready at a different time than the ovule is
- 11:39Speaker 1: ready to accept it, So it's it's a timing thing.
- 11:42Speaker 1: The thing is, peanuts would probably be able to talk
- 11:44Speaker 1: if they didn't self pollinate, and they sound like Jimmy
- 11:46Speaker 1: carter um. So there's a lot of mechanisms that plants
- 11:51Speaker 1: have to prevent themselves from self pollinating. UM. Some or
- 11:56Speaker 1: some might have either just male plants and just female ants.
- 12:01Speaker 1: UM some maybe uh where the male part if the
- 12:05Speaker 1: plant has both male and female flowers, for example, yes,
- 12:11Speaker 1: they they the the male flower might come out before
- 12:14Speaker 1: the female flower on the same plant, so that they're
- 12:18Speaker 1: not the timing is off a little bit. Um. And
- 12:20Speaker 1: then there's some they're just like they'll they'll signal a
- 12:23Speaker 1: biochemical marker. If pollen from the same plant gets near
- 12:26Speaker 1: the ovule, it'll just basically turn barren. So it just
- 12:31Speaker 1: is incapable of fertilizing itself, or like corn where the
- 12:34Speaker 1: timing is thrown off, so they rely on cross pollination, right,
- 12:38Speaker 1: which is pretty cool. So let's let's get explicit again here,
- 12:56Speaker 1: gymnasperms naked seed. How does the happened? Like, We'll use
- 13:01Speaker 1: the example of a pine, a lob lolly pine. It's
- 13:05Speaker 1: fun to say, um, but that's a conifer kind of
- 13:08Speaker 1: furs are ancient. I believe they were the first pollinating plant. Yeah,
- 13:13Speaker 1: I think so. Nice. So let's talk about it. Well,
- 13:16Speaker 1: the pine cones, they're they're little male pine cones, a
- 13:18Speaker 1: little female pine cones. You might not realize that you've
- 13:21Speaker 1: got quite a show going on in your backyard at
- 13:24Speaker 1: certain times of the year, right, Um. And basically, if
- 13:27Speaker 1: once you get the two together, you get a male
- 13:29Speaker 1: pine cone and a female pine cone together. The male
- 13:33Speaker 1: pine cone fertilized, well, the pollen comes in contact with
- 13:38Speaker 1: an ovule, and the pollen starts to go to town.
- 13:41Speaker 1: It absorbs a bunch of water. Well, the female pine
- 13:43Speaker 1: comes little sticky too. That helps, by the way, it does,
- 13:45Speaker 1: helps collect the pollen. Um. So the female or the
- 13:49Speaker 1: the pollen, the male, the male part of the pine
- 13:51Speaker 1: cone germinates and it starts growing. It's called a pollen tube,
- 13:56Speaker 1: which basically allows this pollen to directly for lies the ovule.
- 14:01Speaker 1: Once that happens, the ovule basically becomes a seed and
- 14:05Speaker 1: the seed is released from the pine cone. They go
- 14:08Speaker 1: everywhere and then they're eaten by birds and pooped out elsewhere,
- 14:13Speaker 1: carried along in the there trampled by a rhinoceros who
- 14:17Speaker 1: knows which just got loose from the zoo. But then
- 14:20Speaker 1: that seed is carried along, but it's not protected by anything.
- 14:23Speaker 1: It's just a seed and hence a naked seed. Hence gymnasperms.
- 14:28Speaker 1: So angiosperms they have kind of like a similar process
- 14:33Speaker 1: whereas there's a pollen tube that's grown and the male
- 14:36Speaker 1: pollen has to come in contact with the female pollen
- 14:38Speaker 1: and all that. And we're talking about flowers in most
- 14:40Speaker 1: cases here with andrew sperms, they're the only ones that
- 14:43Speaker 1: flower and produce fruit. So when you think about your
- 14:46Speaker 1: garden with the honey bee and all, that's angiosperm, right,
- 14:50Speaker 1: So that's a non naked seed and that's the that's
- 14:54Speaker 1: where the fruit comes in or the shell comes and
- 14:56Speaker 1: there's area sperms have developed a met achanism to protect
- 15:00Speaker 1: the seed, to better ensure its survival, and if you
- 15:04Speaker 1: think about it, to entice the things that transport these
- 15:08Speaker 1: seeds to go ahead and do their thing. Yeah, there's
- 15:12Speaker 1: like every flower has some sort of cool shape or
- 15:16Speaker 1: scent or color or something that matches with some little
- 15:22Speaker 1: insect or bird or bat that's gonna be enticed. Like
- 15:25Speaker 1: the bumble bee in the fox glove, they go hand
- 15:27Speaker 1: in hand because it fits up there just perfect, and
- 15:30Speaker 1: it has a little colorful landing strip on the bottom
- 15:33Speaker 1: pedal to guide the bumble bee in and it's just
- 15:36Speaker 1: like nature's it's just like harmonious. Yes, there's that one
- 15:40Speaker 1: orchid that I believe Darwin predicted the existence of a
- 15:45Speaker 1: type of hummingbird that had a very long curled beak
- 15:48Speaker 1: right that it co evolves with it and he was
- 15:50Speaker 1: absolutely correct. Remembers in that movie adaptation. Yeah, that's a
- 15:54Speaker 1: great movie. Um, and then, uh, you can learn a
- 15:57Speaker 1: lot from that movie. Yeah, yeah, anything that what's his name,
- 16:01Speaker 1: Charlie Kaufman writes, Yeah, well researched agreed. Um. The fruit
- 16:06Speaker 1: is another thing too. Animals love to eat fruit. The
- 16:10Speaker 1: fruit is basically once the fruit piece of fruit drops
- 16:13Speaker 1: to the ground. That means those seeds are ready to go.
- 16:16Speaker 1: They're ready to become seedlings. But first they need a
- 16:18Speaker 1: fox to eat the apple carried in its stomach over
- 16:22Speaker 1: you know, several meters or miles or whatever, and then
- 16:25Speaker 1: poop it out. And then you have seeds that are
- 16:29Speaker 1: basically just planted. That's amazing. They take purchase and a
- 16:33Speaker 1: new tree begins where his seed her insides where a
- 16:38Speaker 1: rocky place where seed you could find no purchase. So
- 16:42Speaker 1: pollen grains um are actually created. I guess we should
- 16:45Speaker 1: step back a second and talk about myosis. That's the
- 16:49Speaker 1: cells are dividing and growing. Eventually you get a little pollen. Uh.
- 16:53Speaker 1: It looks like a little dust speck to our eyeball,
- 16:56Speaker 1: but it's contains the sperm is not actually the sperm.
- 16:59Speaker 1: It contains into the sperm therein and uh, the pollen
- 17:04Speaker 1: is in pollen sacks at the end of the stamen,
- 17:06Speaker 1: which we talked about, and that little two loabed ant
- 17:09Speaker 1: uh almost aid antler antherer. And then eventually it'll find
- 17:14Speaker 1: its way to the stigma and travel down to the ovary.
- 17:18Speaker 1: And and in the case of angiosperms, there are two
- 17:22Speaker 1: sperm that are used. I don't think we said in
- 17:24Speaker 1: the case of gymnosperms, it's only one of the sperm
- 17:27Speaker 1: is used, right, Yeah, in a in a pollen sect,
- 17:29Speaker 1: there's two sperm, but you just need one for the
- 17:31Speaker 1: gymna sperm for the antio sperm unit to Yeah, because
- 17:34Speaker 1: one is actually fertilizing the egg and the other is
- 17:37Speaker 1: developing into endo sperm together alongside and what will eventually
- 17:42Speaker 1: be the seed. And if you think that sounds gross,
- 17:45Speaker 1: like the gymnos sperm, I'm sorry. The endosperm is like
- 17:49Speaker 1: a protein basically to keep it all alive. Yeah, that
- 17:52Speaker 1: keeps the seedling happy. So when you're eating corn, you're
- 17:57Speaker 1: actually eating the endo sperm. Each corn kernel is actually
- 18:00Speaker 1: you know, it's like that starchy indos form, which the
- 18:03Speaker 1: seed loves to eat itself. And that's true. Um. So
- 18:08Speaker 1: we talked about bees, we talked about birds, foxes, mentioned
- 18:13Speaker 1: poopa a couple of times. Yeah, and you were saying
- 18:17Speaker 1: that like basically every every flowering plant, especially has some
- 18:21Speaker 1: sort of mechanism to attract at least one kind of
- 18:25Speaker 1: um bug or animal that's been proven to help pollinate,
- 18:30Speaker 1: transport this pollen and so I mean for the most part,
- 18:33Speaker 1: we enjoy them, like you like the scent of you know,
- 18:37Speaker 1: a good flower, right, sure, but you might not like
- 18:42Speaker 1: the Devil's Tongue, yeah, which is a sumatran plant that
- 18:47Speaker 1: apparently reaks so badly it smells like a decomposing flash. Basically, basically,
- 18:53Speaker 1: did you see this thing? I've seen it before. You
- 18:55Speaker 1: actually remarkable like two feet and it's like it it
- 19:00Speaker 1: basically um flowers or blooms like once every like ten
- 19:03Speaker 1: years or twenty years something like that. Right, I'm not
- 19:06Speaker 1: sure if it's the same one. I'm thinking of things.
- 19:08Speaker 1: But it's stinky, right, And the reason why it's stinky
- 19:11Speaker 1: is because it pollinates with the help of a type
- 19:14Speaker 1: of carrion beetle that's attracted to decomposing flesh. So the
- 19:18Speaker 1: plant attracts this beetle that likes to eat decomposing flesh
- 19:22Speaker 1: by putting out the smell of decomposing flesh. That's so gross, yeah,
- 19:27Speaker 1: but it's pretty spectacular, it is, you know. Yeah, in
- 19:30Speaker 1: the philodendron, something you might have in your house. It
- 19:32Speaker 1: actually does the same thing, but it doesn't stink always. Um.
- 19:36Speaker 1: There's actual chemical reaction that takes place and heats it
- 19:39Speaker 1: up to omit this odor that the beetle is attracted to,
- 19:42Speaker 1: which sounds pretty gross too, but it all works, and
- 19:46Speaker 1: I would google that um the sumatra and devil's tongue.
- 19:49Speaker 1: It's pretty cool looking. Like the flower itself is two
- 19:52Speaker 1: feet It's not like, oh, what a long stem, It's
- 19:55Speaker 1: just this huge flower. It's amazing. And then you're also
- 19:57Speaker 1: saying like, was it fox glove that provided a landing
- 20:01Speaker 1: strip for bumblebees? Yeah, So flowers in general typically have
- 20:06Speaker 1: certain types of um like their color will be based
- 20:09Speaker 1: on the kind of creature that um that that helps
- 20:13Speaker 1: pollinate it, whether it's diurnal meaning it it's awake during
- 20:17Speaker 1: the day or nocturnal meaning it's awake at night. Right, right,
- 20:20Speaker 1: I guess that's in case of like bats and stuff
- 20:22Speaker 1: like that. Yeah, and then our old friend nectar is
- 20:25Speaker 1: a big lure and basically nectar is around right, just
- 20:30Speaker 1: because it tastes delicious and is enticing from what. Yeah,
- 20:34Speaker 1: it's basically like a little enticement like you said, for
- 20:37Speaker 1: like a bee or something or a bird. Yeah, come
- 20:40Speaker 1: get it. Because it's placed by the stamen that's right,
- 20:45Speaker 1: or the way that the the anthers are situated just
- 20:48Speaker 1: the way they're placed in the flower. If it gave
- 20:50Speaker 1: it an advantage to bump up against that bee, then
- 20:53Speaker 1: it's gonna be successful in the long run and live
- 20:56Speaker 1: out as a species as nice stuff that is pretty good. So, chuck,
- 21:00Speaker 1: we've reached a point where, um, I mean, ever since
- 21:03Speaker 1: we started selectively breeding plants, domesticating crops like hey, that's
- 21:07Speaker 1: pretty right, or hey I like this banana um or
- 21:11Speaker 1: that's hardy and it grows in my awful hot area
- 21:15Speaker 1: that I live in, many reasons to do so, right, Um,
- 21:20Speaker 1: you know, we we wanted to keep plants, we wanted
- 21:24Speaker 1: to keep the bad stuff out, keep the good ones
- 21:27Speaker 1: we wanted in. But it never became more crucial, um
- 21:30Speaker 1: until we started genetically modifying crops. And now all of
- 21:35Speaker 1: a sudden, not only are the corporations saying like, hey man,
- 21:38Speaker 1: you can't cross pollinate with our stuff for else that's
- 21:41Speaker 1: patent infringement, and nearby farmers says, I'm not using your
- 21:45Speaker 1: seeds as the bees, you can't blame me, and the
- 21:48Speaker 1: farmers who don't want GMO stuff in their crops say,
- 21:52Speaker 1: hey man, you need to keep your crops over there
- 21:55Speaker 1: because I don't want your GMO creud in here. I
- 21:58Speaker 1: have an organic farm exactly, and you're just blowing by
- 22:02Speaker 1: the wind. It's a touchy subject. We should do that
- 22:05Speaker 1: as the GMOs. I agree. The idea of like patenting
- 22:08Speaker 1: jeans in general and alone like crops is it's really interesting. Um,
- 22:13Speaker 1: but there's been some pretty clever, simple ways of getting
- 22:17Speaker 1: around this problem. It's posed by pollination of GMO crops
- 22:21Speaker 1: with non GMO crops. Yeah. Well, distance is obviously one thing.
- 22:28Speaker 1: Don't put my farm near your farm. But they have
- 22:30Speaker 1: to do all kinds of studies to see how the
- 22:32Speaker 1: wind reacts and how like how far does that be fly? Yeah,
- 22:35Speaker 1: and they found in uh, in certain parts of Africa,
- 22:38Speaker 1: these will go about four miles three kilometers. That's their
- 22:42Speaker 1: range for food. That's you know, that's a lot. Yeah.
- 22:45Speaker 1: But I mean just using that kind of thinking with
- 22:48Speaker 1: all process though, like okay, well this you know, there's
- 22:51Speaker 1: this guy's growing this over here, so I can't grow
- 22:53Speaker 1: this here, right, That will prevent that kind of pollination though. Yeah.
- 22:58Speaker 1: Another thing they can do is uh, sort of like
- 23:00Speaker 1: with the corn, they can time their crop rotation to
- 23:03Speaker 1: time out so where they're flowering at different times and
- 23:06Speaker 1: not interfering with one another. But um, it's a touchy subject.
- 23:10Speaker 1: Like from what I understand, there's a lot a lot
- 23:12Speaker 1: more going on then you know, is preferred by like
- 23:17Speaker 1: the organic farmers of the world, and in't the GMOs.
- 23:22Speaker 1: They can then say that you're infringing just because they
- 23:26Speaker 1: cross pollinated to their crop, even though you didn't buy
- 23:30Speaker 1: their seeds or even want their seeds. If a bee
- 23:34Speaker 1: carries there, it's there's seeds, there's crops falling over to
- 23:39Speaker 1: your crops. And you start to develop plants that have
- 23:42Speaker 1: the GMO characteristics that's patented. According to the corporations, you're
- 23:47Speaker 1: infringing on their pat It's very tricky ground, there isn't it.
- 23:50Speaker 1: I don't think it's tricky ground. If you ask me,
- 23:53Speaker 1: you should not be allowed to have a patent on
- 23:55Speaker 1: any living organism. Oh well, yeah, you know what I mean, though,
- 23:58Speaker 1: that's my opinion. It gets tricky, uh in courts and
- 24:01Speaker 1: studies and corporations and the course to tend to side
- 24:05Speaker 1: on the corporation's side. Typically. Let's do that one though
- 24:11Speaker 1: soon g MS. Yeah all right, Um, so let's say
- 24:14Speaker 1: for Paullen, if you're interested in how pollen causes allergies
- 24:18Speaker 1: and you should listen to our how Allergies Work episode
- 24:20Speaker 1: That was pretty good. Yeah, I was gonna recommend that.
- 24:22Speaker 1: Nice work. Um, thanks man. So, uh, if you want
- 24:26Speaker 1: to learn more about pollen in the meantime, you can
- 24:28Speaker 1: type that word in the search bar how stuff works
- 24:30Speaker 1: dot com. Since I said search bar, it's time, of
- 24:32Speaker 1: course for a message break. And now how about some
- 24:56Speaker 1: listener mail. Yeah, we have correction. It's been blowing up lately.
- 25:02Speaker 1: Oh man, I'm sorry. You know it's crazy. Is that's
- 25:05Speaker 1: the second time I've done that and a podcast on
- 25:08Speaker 1: that same same thing. I don't remember what the other
- 25:11Speaker 1: podcast was, but I've mentioned it before and we've gotten
- 25:13Speaker 1: tons of corrections about it and I didn't learn my lesson. Well,
- 25:16Speaker 1: this guy was really nice about it, so I'm gonna
- 25:19Speaker 1: read his. And it's an important correction because anytime you're
- 25:22Speaker 1: talking about drugs, so to recap in the PTSD podcast,
- 25:26Speaker 1: we got the two drugs beta blocker called propan and
- 25:30Speaker 1: all which helps with PTSD, confused with propofol, which is
- 25:35Speaker 1: what killed Michael Jackson. And so this is from Chris.
- 25:39Speaker 1: He's a big fan. He's listened to every episode on
- 25:42Speaker 1: his commute in southern California, which we know stinks. So
- 25:47Speaker 1: he said what we just said about the getting the
- 25:49Speaker 1: drugs confused, He seconds, see how you guys can mix
- 25:51Speaker 1: it up because the names are very similar, but they're
- 25:53Speaker 1: significantly different. Obviously, propan and all is relatively mild and um,
- 26:00Speaker 1: I'm only prescribed and very little potential for overdose, while
- 26:03Speaker 1: a propofile is a very powerful drug, extremely high potential
- 26:06Speaker 1: for overdose, and rarely administrated outside of strictly monitored medical settings.
- 26:11Speaker 1: It is actually a hypnotic agent that must be administered
- 26:14Speaker 1: intravenously because we talked about Michael Jackson's drip, and is
- 26:18Speaker 1: often used in conjunction with general anesthetics. Like most general anesthetics,
- 26:22Speaker 1: it's steep dose response curve significantly increases the risk of overdose,
- 26:27Speaker 1: where the effective dose is only slightly below a lethal dose.
- 26:31Speaker 1: That's kind of scary, Yeah, it really is. I mean,
- 26:33Speaker 1: like when you're when you're on that, like you're right
- 26:36Speaker 1: along the border. Yeah. Well, he says, Michael Jackson's case
- 26:39Speaker 1: is extremely rare, as he was essentially exposing himself to
- 26:42Speaker 1: risk similar to those associated with general anesthetics used during
- 26:46Speaker 1: surgery with a higher potential for overdose and death on
- 26:49Speaker 1: a daily basis for a relatively trivial purposes, which were
- 26:54Speaker 1: in this case is insomnia. Yeah, but from what I understand,
- 26:58Speaker 1: he had like years long insomnia. Like this guy was
- 27:01Speaker 1: not sleeping at all, Like they would they wouldn't, They
- 27:05Speaker 1: would give him everything first, and then they try that
- 27:07Speaker 1: last resort and like sometimes it's still wouldn't work. Really, Yeah,
- 27:13Speaker 1: he was really in bad shape at the end. Well,
- 27:15Speaker 1: he probably had a resistance to certain ship things like that.
- 27:19Speaker 1: So Chris goes on to say, I'm not certain about
- 27:21Speaker 1: the exact amount of risk posed by propofile administration, but
- 27:25Speaker 1: I believe the risk of death is something on the
- 27:26Speaker 1: order of tenths of a percent, meaning he would have
- 27:30Speaker 1: died according to the statistical model, within a couple of
- 27:33Speaker 1: years of daily use, like British guaranteed. Frankly, he would
- 27:36Speaker 1: have been better off using heroin that whole time, in
- 27:39Speaker 1: spite of his ironically strict yet poorly informed anti drug stance.
- 27:44Speaker 1: So that's from Chris. Thanks Chris. I was a genuinely
- 27:47Speaker 1: awesome email. That was good, um, and I'm sorry everybody
- 27:50Speaker 1: freaking so wrong. Well, I mean the names are just confusing. Yeah,
- 27:53Speaker 1: but I mean one's like a blood pressure medicine. The
- 27:55Speaker 1: other one's like pretty much a general anesthetic. I know.
- 27:58Speaker 1: But what gets me is that half of the emails
- 28:01Speaker 1: were like, well, yeah, they just sound alike, so you
- 28:04Speaker 1: goofed it in. Half of them were like those drugs
- 28:06Speaker 1: couldn't be anymore different, like you really thought of it,
- 28:09Speaker 1: you know. It's just it's like a verbal TYPEO. Thank you, chuck. Yeah,
- 28:13Speaker 1: thanks for letting me off anyway. Uh, if you have
- 28:16Speaker 1: a correction for us, we really do like to get those.
- 28:20Speaker 1: We like to know what we're talking about. Sometimes we
- 28:22Speaker 1: get we get things wrong. Sometimes I get things wrong,
- 28:26Speaker 1: but we do want to be corrected. Happens in the
- 28:29Speaker 1: nicest way possible, because that's usually who gets their letter
