Staph Retreat

Episode Summary

In the episode titled "Staph Retreat," Latif Nasser revisits a story he reported in 2015, which delves into the realms of science, miracles, Vikings, and a potentially hazardous kitchen experiment. The narrative begins with the accidental discovery of penicillin by Alexander Fleming in 1928, a breakthrough that transformed the treatment of infectious diseases. However, the episode quickly shifts focus to the emergence of antibiotic resistance, a phenomenon that was observed almost concurrently with the introduction of penicillin and other antibiotics. This resistance has led to an arms race between new drugs and evolving bacteria, resulting in a dire situation where modern medicine is running out of effective antibiotics. The story then takes an intriguing turn as Nasser introduces Dr. Christina Lee, a Viking studies scholar, and Dr. Freya Harrison, a microbiologist, who embark on an unusual collaboration. Inspired by their shared interests in history and microbiology, they decide to test a 1,100-year-old remedy for eye infections found in Bald's Leechbook, an ancient Anglo-Saxon medical text. The remedy, which includes ingredients such as onion, garlic, wine, and bile from a cow's stomach, was believed to be effective against styes, infections caused by the bacterium Staphylococcus aureus. Despite initial skepticism, their experiment shows that the ancient concoction is remarkably effective at killing antibiotic-resistant bacteria, including MRSA, a notorious superbug. This discovery opens up a fascinating discussion about the potential of ancient remedies in the fight against antibiotic resistance. The episode explores the idea that historical medical practices, often dismissed as superstition, may hold valuable insights for modern science. It suggests that by revisiting and reevaluating these ancient cures, researchers might find new solutions to contemporary health crises. The story of Bald's Leechbook serves as a reminder that progress is not always linear and that the past may offer unexpected resources for the future. "Staph Retreat" ultimately presents a compelling narrative that bridges the gap between the past and the present, challenging listeners to reconsider their perceptions of medical history and the ongoing battle against antibiotic-resistant bacteria. Through the unlikely partnership of a historian and a microbiologist, the episode highlights the importance of interdisciplinary collaboration and the potential benefits of combining historical knowledge with scientific inquiry.

Episode Show Notes

What happens when you combine an axe-wielding microbiologist and a disease-obsessed historian? A strange brew that's hard to resist, even for a modern day microbe. In the war on devilish microbes, our weapons are starting to fail us. The antibiotics we once wielded like miraculous flaming swords seem more like lukewarm butter knives. But today we follow an odd couple to a storied land of elves and dragons. There, they uncover a 1000-year-old secret that makes us reconsider our most basic assumptions about human progress and wonder: What if the only way forward is backward? Reported by Latif Nasser.

SPEAKER_06: Hey, I'm Latif Nasser.Today, I'm going to play you an old episode that I reported way back in 2015.It's got science.It's got miracles.It's got Vikings.It's got a potentially hazardous kitchen experiment performed by senior producer Matt Kielty and I. And what I really love about this episode is how it makes you see progress not as a straight line, sometimes not even as a line at all.Sometimes it's actually a circle.I swear it'll make sense at the end of the episode.I now present to you Staff Retreat. Wait, you're listening?Okay.All right.Okay.All right. SPEAKER_15: You're listening to Radiolab. SPEAKER_04: Radio from WNYC.Rewind. SPEAKER_05: Hey, I'm Jad Abumrad. SPEAKER_02: I'm Robert Krolwich.This is Radiolab, and today... Well, today... Yes.The story of an axe-wielding nun coming through a window to smack some staphylococcus and take you back to the future. SPEAKER_05: Exactly.The story comes... Does that make any sense?I don't know. SPEAKER_02: Well, it will. SPEAKER_05: Okay, it will.The story comes in two parts, both from our producer Latif Nasser, and here is part one. SPEAKER_06: So the way the story goes, it starts in 1928. SPEAKER_08: 1928, Alexander Fleming, the story goes, who knows if it's apocryphal or not, is growing staph, Staphylococcus, in his lab. SPEAKER_06: That's Maren McKenna.She's a science writer.And staph is a bacterium. SPEAKER_08: It lives on our skin, and it especially likes parts of the body that are warm and damp. So it likes to be just up our noses or in our genitals or in our armpits, places like that. SPEAKER_06: And generally, it's no big deal.Doesn't really do us any harm.But if it gets into a scratch or a cut and makes its way inside our bodies, staph goes from being this benign companion to being potentially deadly. Anyway, London, 1928.Fleming is growing staff in his lab.In these little petri dishes.And he was a slob, basically.And he goes on a vacation, leaves his petri dishes, covered in bacteria, just around, leaves his window open. SPEAKER_08: And something blows across his lab plates. SPEAKER_06: Some tiny little speck of a thing just floats in through the window and comes to a rest on one of those Petri dishes.And so a few weeks later.Fleming, finally, back from vacation. SPEAKER_08: He needs to use those lab plates again, and he and his assistant go to clean them off. SPEAKER_06: I mean, you'd imagine that he would see some real lush, nice, furry lawn of staff just overflowing right out of the plate.Because it's been sitting there for so long.It's been a staff party. SPEAKER_08: But on one of the plates that they pick up, they realize that it's almost polka dot.It's got little dead zones all over it. SPEAKER_06: Little patches where the staff is dead. Dead patches. SPEAKER_03: So something blew through the window, landed in the dish, and starts killing the bacteria. SPEAKER_06: Yeah, and so when Fleming looks down at his plate, he sees that at the center of these, you know, staff dead zones, there's a tiny speck of natural mold. SPEAKER_08: Of mold.And they realize that that mold is expressing a compound that is killing the staff around it. SPEAKER_06: It's like emanating rays of death.What was the compound?That compound was called... Penicillin. SPEAKER_08: The first true antibiotic.Infectious diseases that had been killing people for as long as we had been people suddenly could be stopped. SPEAKER_06: And it just blew in through the window? SPEAKER_08: That is the story that's always been told. SPEAKER_06: However it got there, it was amazing.It was a miracle.It was called a miracle drug, right? SPEAKER_08: I mean, it was just, it really was a moment when the world changed.When Fleming was put on the cover of Time magazine. SPEAKER_06: This was 1944, height of World War II. SPEAKER_08: It was a picture of his face and the banner on the cover said, his penicillin will save more lives than war can spend. SPEAKER_06: But, and this is, I had no idea about this.Virtually at the exact same time when Fleming's face is on the cover of Time magazine, like two months later, this Stanford researcher publishes that he has found five different strains of staph. that do not respond to penicillin.Really?Yeah.This is happening while he's on the cover?Virtually the exact same moment. SPEAKER_08: And it's the first sign that staff has responded to the penicillin in the world by developing resistance. SPEAKER_17: It's almost like, uh... Set producer Soren Wheeler?The era of penicillin was over before it began. SPEAKER_08: Almost before it began. SPEAKER_17: Before it's even released to the general public. SPEAKER_06: Wow. SPEAKER_08: And that penicillin-resistant staph moves across the globe. SPEAKER_06: And in 1957, in Cleveland, some scientists gather together. SPEAKER_08: And they are in a panic.They have no idea why they've lost the antibiotic miracle so quickly. SPEAKER_06: So scientists across the globe put their brains together and try to come up with a new drug. SPEAKER_08: The next amazing thing. SPEAKER_06: And in 1960, they get it. SPEAKER_08: Methicillin. And it works for about 11 months. SPEAKER_06: Eleven months?And so we started this arms race. SPEAKER_08: There was a bug, and then there was a drug that took care of it, and then there was a better bug. SPEAKER_06: Drug bug, drug bug. SPEAKER_08: Right, exactly. SPEAKER_06: I actually found this list.Do you want to hear it?Yeah.Okay, so streptomycin, 1943, resistance 1948.Methicillin, 1960, resistance 1961.Clindamycin, 1969, resistance 1970.Wow. SPEAKER_08: You can think of it as leapfrog, or you can think of it as a game of whack-a-mole. SPEAKER_06: Ampicillin, 1961, then 1973, so that's a little.Carbenicillin, released 1964, resistance 1974.They're getting better, they're getting better. SPEAKER_08: There were always more drugs.Drug development was doing really well for a really long time. SPEAKER_06: Hypericillin, introduced 1980, resistance 1981.Jesus. SPEAKER_08: But after the year 2000, drug companies begin to realize it's not really in their best interest to make antibiotics anymore. SPEAKER_06: And the end I have on this list is linazolid, which is introduced 2000, resistance 2002.Wow.There are a few more, but you get the idea. SPEAKER_08: Antibiotic approvals, the entry of new drugs to the market, just kind of fell off a cliff. SPEAKER_06: Why? SPEAKER_08: Well, it takes 10 years and a billion dollars to get to the point where the drug is marketable. SPEAKER_06: But as soon as you get the drug on the market... The resistance clock is running.So you probably won't make your money back.And as you've probably heard, we now have these situations where... SPEAKER_11: A frightening new warning from the Centers for Disease Control about the spread of a string of germs... Where literally nothing works.So-called superbugs are now turning up in hospitals... And the patient dies. SPEAKER_06: There are now bugs that can resist all of our drugs. SPEAKER_08: I have seen physicians break down weeping over this.It's not the way that medicine is supposed to fail anymore, but it does. SPEAKER_17: I mean... I know that possibly the origin story of penicillin is apocryphal.So this is all a little suspect.But, you know, just to enjoy imaginings for a moment, like it just seems like if that happened, let's just open up a bunch more windows.Something ought to blow in. SPEAKER_08: But we could wait a long time, right?I mean, we had staff had been around for millennia before 1928.Right. SPEAKER_06: But, you know, the whole reason that I wanted to do this story is because kind of there is a new window.It's a different kind of window, though.Not a window next to some Petri dishes?Not a window next to some Petri dishes.Kind of a window next to some Petri dishes. But a totally different kind of window.What kind of window is it?Well, I'm about to tell you that.Is something blowing to the window?Yeah, but it's not mold. It's way more fun than mold.It carries an axe.How about that?So it's a person.Maybe.I don't even know what I'm referring to anymore. SPEAKER_01: Radiolab is supported by BetterHelp.Whether it's already 2am on a fun night out, graduation time, a new year, we can find ourselves wishing we had more time, wondering where it all went.But there's a question.If we were magically given that time back, what would we do with it?

SPEAKER_05: Part two?Yeah.Okay.Hey, I'm Jad Abumrad.I'm Robert Krolwich.This is Radiolab.We're ready now for part two. SPEAKER_03: Now, remember when part one ended, there was a window open and something was going to come through.We don't know what.We know it's not mold.Yeah, we know it's not mold.So whatever it is, whatever it was, whatever it will be, we will hear about it now from our reporter, Latif Nasser. SPEAKER_06: Well, actually, there is this story about these two women who did open a window. To an alien and distant land.And actually, in a way, it's a story about reimagining the past.But to me, it's a story about a friendship.Hey, everybody. SPEAKER_10: Hello again.Hello again. SPEAKER_06: It's a story about an unlikely friendship.It's a buddy film.Yeah, it's a buddy movie.Okay, so maybe just walk us through it.Right.Okay, so you have... Hello, I'm Dr. Christina Lee. SPEAKER_10: Christina. SPEAKER_06: Christina. SPEAKER_10: And I'm an associate professor in Viking studies at the School of English at the University of Nottingham. SPEAKER_06: She's a historian.And then you also have... Hi, I'm Freya Harrison. SPEAKER_09: Freya.I'm a research fellow in the Centre for Biomolecular Sciences at the University of Nottingham. SPEAKER_06: And Freya's a microbiologist.She studies bacteria.We'll start with her. SPEAKER_09: Okay.So most of my work is about sort of looking at how bacteria evolve during very, very long-lived infections.But... My big hobby is Anglo-Saxon and Viking reenactment. So I had a purely sort of amateur interest in the history and mainly in dressing up as a warrior and going to fight club every Wednesday night and learning to use the weapons. SPEAKER_06: Really? SPEAKER_09: Yeah. SPEAKER_06: So this is actually not Freya's group.This is a group in New Jersey, but basically they do the same thing.Hundreds of people go out into, you know, some field with some dulled weapons. SPEAKER_09: Everything from swords, spears, axes, and... We give each other a jolly good bashing and have a good time. SPEAKER_06: I only mention this because it actually plays into the story. SPEAKER_09: Well, it was a really nice sort of coincidence, really.2012. SPEAKER_06: A few years after finishing her doctorate, Freya goes off to work at the University of Nottingham. SPEAKER_09: Nottingham is one of the places in the UK, not only for microbiology, but for Anglo-Saxon and Viking history. SPEAKER_06: And she goes there to study microbes, but she figures, hey, why not, while I'm here, brush up on my old English? SPEAKER_09: I'd studied some old English to a level where I could sort of read and... and speak a little bit. SPEAKER_06: But she figured, hey, she could be better.And if she did, she would get deeper into the whole reenactment thing. SPEAKER_09: So I rather cheekily emailed the School of English's Old English Reading Group. SPEAKER_06: That's where she met Christina. SPEAKER_09: Yes! SPEAKER_06: The historian. At one point, Christina, the historian, asks Freya, like, what do you do?And Freya said, you know, my day job is that I'm a microbiologist, but on evenings and weekends, I'm a history nerd.And Christina said the moment she heard that... I just kind of thought, I've found my kindred spirit here.Because she was like, wow, I'm like your mirror image, because I'm a historian by day, but by night, I'm a microbiology nerd. SPEAKER_10: I've been interested in infectious disease for quite a long time, which... I don't find any kind of friends in my department. SPEAKER_06: She told me she's the kind of person who would, you know, watch Ebola coverage on the news and not be able to stop watching.So eventually they start talking about historical diseases. So, like, how would people back then have treated something like, you know, Ebola?Freya is especially interested in this because she, for her historical reenactment, is developing this nun character who goes off and heals people.But anyway, so they're talking back and forth.And then to cut a long story short, they find themselves both interested in this one particular book. SPEAKER_09: It's known as Bald's Leech Book.So this is about 1100 years old. SPEAKER_03: What's it called?Bald's what?Bald's Leech Book. SPEAKER_10: It's nothing to do with no hair.Oh.Even though it is spelled. SPEAKER_18: Is it B-A-L-D? SPEAKER_10: It is indeed. SPEAKER_18: And leech, like leech, like a leech, like a little worm that grabs onto your, sucks your blood? SPEAKER_10: No, no, it comes from the old English word lecher, which is actually a healer or a doctor. SPEAKER_09: So that the little squiggly animals are called leeches because they're medicinal, not the other way around. SPEAKER_06: Oh.So the doctor wasn't named for the leech, the leech was named for the doctor. SPEAKER_09: Exactly, yeah. SPEAKER_06: And Bald is a man?The guy who wrote the book? SPEAKER_09: We think it's a guy.We think it's a guy's name. SPEAKER_06: And what is this book?So it's kind of like this old healer's handbook.It's filled with these potions and cures.The original manuscript is in the British Library.Locked away. SPEAKER_09: But... 21st century, very kind people have digitized the original Old English text and put it online. SPEAKER_06: So Christina and Freya bring it up and they start going through all the remedies. SPEAKER_10: And, you know, it describes to you remedies for stuff that is... A little bit different. SPEAKER_07: You know, things like... Possession by the devil. SPEAKER_06: Which, according to this leech book, the remedy for someone who is possessed by the devil is you... Make this kind of like foul brew.You make them drink it, and it'll make them vomit out the devil.And then there's another remedy for warts.And all I'm going to say about that one is that it involves hound's urine and mouse blood. SPEAKER_09: And then things like... How shall we say, make your husband more physically attentive or less physically attentive, whichever direction you need to moderate it. SPEAKER_18: Pig's blood, I hope, or toad blood. SPEAKER_06: Actually, it's just you boil a plant in some water and give it to the guy.Oh. Yeah.Anyway.So Free and Christina are going through this leech book, looking for some kind of wound.Something that was clearly an infection.Some pussy something. SPEAKER_09: Something we could clearly say that's bacterial. SPEAKER_06: And eventually they find an entry. SPEAKER_09: Where at the end of the recipe it says in Old English. SPEAKER_07: The best medicine. SPEAKER_09: The best medicine. SPEAKER_06: Yeah, move over laughter. SPEAKER_09: Yeah.And we thought, how can we not try this one? SPEAKER_06: What was the best medicine for? SPEAKER_09: So it said it was for a lump in the eye.It's actually called wen in Old English. SPEAKER_10: These days, if you get a, of course, that could be something like a wart, right?But there is a suggestion by archaeologists that eye infection was rife amongst the Anglo-Saxons because you lived in buildings where you had smoke going on. We lived crammed together.So it could also be a stye. SPEAKER_09: What is a stye?It's an infection of an eyelash follicle.You rub it and it itches and then it gets swollen.Yeah, and it causes quite a nasty red lump. SPEAKER_06: It's a stye in your eye.Stye in your eye.Now, it just so happens that the bacteria that causes the stye in your eye is... Staphylococcus aureus.Staph. SPEAKER_05: Oh, the same stuff as the Mr. Window Man, Penicillin Man. SPEAKER_06: Exactly. SPEAKER_09: And we just thought... Wouldn't it be nice to have a bit of spare time and a couple of hundred quid to buy the ingredients and just give this a go?Yes, let's give it a try.You know, why?Why the hell not? SPEAKER_06: And matter of fact, look at this place.We thought that, too.Not bad.Recently, producer Matt Kielty and I went to my tiny apartment in the city and we tried to cook it up, too.Are you ready to cook?Oh, I'm ready to cook. SPEAKER_09: I've got this recipe here if you'd like it. SPEAKER_06: Oh, awesome.Yeah, yeah, yeah.Please read it. SPEAKER_09: Go for it.Okay. SPEAKER_06: It goes like this.That's the first line of the recipe.And right off the bat for Christina and Freya, there's a problem.That first ingredient. SPEAKER_09: The word kropliach.Kropliach. SPEAKER_06: Kropliach. SPEAKER_09: Christina said it was quite difficult to translate.Nobody quite knows what it is. SPEAKER_06: But luckily... Just a couple words over was a clue.And garlic.The second ingredient. SPEAKER_10: Garlic, which is an allium species.We know this was another allium.That's what the dictionary of Old English tells us. SPEAKER_06: So they figured probably what they were dealing with was an allium. onion or leek. SPEAKER_09: But we didn't know which one.So we thought, okay, we'll try one that has onion and one that has leek. SPEAKER_06: Now, the recipe doesn't cover this, but we did it anyway.Peel the onion, chop it up. The same for the garlic. SPEAKER_10: And the recipe, it doesn't tell you how much.It just tells you equal amounts of. SPEAKER_06: So you take out the measuring cups, you measure out equal amounts.Yeah, equal amounts.Into the pestle.And then after that... Okay, it says... Pounded well together.Okay. SPEAKER_10: But you have to be really pounded.And pounded Freya did. SPEAKER_09: Yeah, yeah, so... Lots of time with the mortar and pestle.Mussels built up from wielding a sword for pounding the ingredients. SPEAKER_06: Look, it's starting to be more of a mush.Third ingredient? SPEAKER_09: The next one was definitely something you wouldn't have knocking around in your kitchen. SPEAKER_07: Ox gall.Ox gall. SPEAKER_09: Bovine bile from a cow's gallbladder. SPEAKER_18: What, do you have to kill the cow and then go reach it? SPEAKER_09: No, it's actually a very standard ingredient in microbiology labs. ox bile today in 2015 you can but should not just buy it on the internet here we go here we go and so you take the ox bile add it to the onion and garlic and then the fourth ingredient wine and wine time red wine white wine what like what kind of wine are we talking about here this is the thing so we had quite a discussion about what type of wine should we use and we don't know really did they have red wine did they have white wine what was the alcohol content but i did a bit of bit of detective work SPEAKER_06: And she figured out that the monastery where this leech book was written, well, she figured out where their vineyard was. SPEAKER_09: And just down the road, there's this modern organic vineyard. SPEAKER_06: So they used that wine.I just want to point out how difficult it is to find English wine.We had to use Italian.Once you get all that stuff together, you're onto the final ingredient. SPEAKER_09: The fifth ingredient was actually that you're specifically told that you have to mix these ingredients together in a brass or a bronze pot.I don't have one.So we had to sort of add pieces of copper that would have been available to people at the time. SPEAKER_06: So they had to do some research, but they figured out that the copper of today that is most like the copper of a millennium ago was actually cartridge brass, which is what's used as standard in plumbing fittings.Dropped a few pennies in there.We actually use pennies.Do I stir it?I think I stir it.This is like a world's worst cooking show. SPEAKER_09: And it looks and smells like quite a nice, quite a nice summer soup. SPEAKER_06: Oh, that's awful.Oh, that's so gross.Clearly, we botched this whole thing.And finally.So we're going to cover it.OK, we're covering it.The directions say we have to let the whole thing sit for a while. SPEAKER_09: It has to be stored for nine days and nights. SPEAKER_17: OK, that's it. SPEAKER_03: One day goes by two days, three, four, five. SPEAKER_06: Six, seven, eight, nine.All right.Nine days later.All right, here we go.You ready?Mm-hmm.All right, here we go. SPEAKER_07: And... Then you have to strain it through a cloth. SPEAKER_09: The liquid that comes off, you apply to the person's eye. SPEAKER_07: Oh, the liquid.And umnigt domid federe.Yeah, with a feather.Se betsta lacedon. SPEAKER_06: Now, clearly, we didn't have any staff to try this out on, but Freya, in her lab, she made these mock wounds. SPEAKER_09: With these little plugs of collagen, so it's a bit like jelly. SPEAKER_06: Basically, it's like a goopy substance made to be kind of like a flesh wound. SPEAKER_09: And we infect these wounds with bacteria with the staff. SPEAKER_06: Then they put this thousand-year-old recipe that had been standing there for nine days, they put it on the bacteria that was in the fake wound. SPEAKER_09: Obviously, we didn't think this was going to work.No.We thought, you know, well, given the ingredients, we might see some small killing effect on the bacteria, but it won't be anything to write home about. SPEAKER_06: They thought maybe it'd kill 10%, 20% of the bacteria.But then when they came back the next day... It was a staff massacre.It went on a rampage.It went on a staff rampage. SPEAKER_09: It was killing, you know, 99.99999% of these bacterial cells.Wow. Yeah.First, we thought we made some sort of mistake and this was some kind of fluke.You know, we'd accidentally mixed up our plates or mislabeled something. SPEAKER_06: So they run the entire experiment again.They grab the ingredients, mash them up, put them on some bacteria, and it happens again. SPEAKER_09: Just absolutely wiped out the bacteria in these plate wounds. SPEAKER_06: Then they tried a third time and a fourth and a fifth, and it works every time. SPEAKER_09: This is just something you really don't. see in your career as a microbiologist. SPEAKER_06: And eventually, they escalated from just regular staff to MRSA. to the methicillin-resistant stuff.And this is one of the bad ones. SPEAKER_08: A superbug.New government data estimate that about 2,000 people are dying of community-based MRSA every year.This one is very dangerous. SPEAKER_06: So Christina and Freya, they sent some of Bald's brew to one of their collaborators in the States. SPEAKER_09: Our collaborator Kendra Rumbau in Lubbock in Texas. SPEAKER_06: Kendra took the stuff, put it on some MRSA bacteria, and then a week later sent Freya and Christina an email. SPEAKER_09: And I think it was actually a three-word response.I think she just simply said, What the f**k?What the f**k? SPEAKER_06: Bald's best medicine had just wreaked havoc on the MRSA.It killed 90% of them.This is beyond our wildest dreams.Now, Frey and Christina made very clear that this is not yet a miracle drug.I mean, it's not even been tested in humans. SPEAKER_10: So, absolutely not. Do not do this at home. SPEAKER_06: They don't even know if this is safe. SPEAKER_09: It might be that if you don't do it in exactly the way we did, nasty fungus could grow in it, give you a worse infection. SPEAKER_06: So, uh... We should not have done this.Matt and I, we... dump cars down the drain but the thing about this whole story that is so intriguing and so cool to me is this time travel thing which is so strange like it's like the idea that something a thousand years ago uh like a bullet forged a thousand years ago we could we could use it now and then it could work that that the time travel dimension of that is so weird to me It kind of makes you think differently about, I don't know, progress. SPEAKER_00: So, without much further ado, Dr. Christina Lee and Dr. Freya Harrison, and they're going to talk to us about some ancient biotics. SPEAKER_06: For example, just a few weeks ago, Freya and Christina got up in front of the Royal Society of Chemists. SPEAKER_10: Thank you very much, and it is an absolute pleasure to be here. SPEAKER_06: Large hotel conference room, 100 or so people.Freya actually got up on stage dressed as a nun. SPEAKER_09: Okay, so this is one interpretation of what an Anglo-Saxon scientist may have looked like. SPEAKER_06: And they presented the results. SPEAKER_09: Next ingredient... SPEAKER_06: They did the cooking demo.And then at some point, Christina said something really interesting.She was like, OK, sure, we want to write this off because it has demons and dragons and elves in it.But are we sure that we know what they meant by those words?Like, for example. SPEAKER_10: There are remedies which ask you, sing for Ave Maria's. SPEAKER_06: And we would say, oh, that's so superstitious.This is all in their heads. SPEAKER_10: But there again, we should also remember, this is a period when people do not have watches.You do not have your nurse, you know, so that's got the watch.Everybody knows the Ave Maria.Everybody knows the length of an Ave Maria. SPEAKER_06: So maybe it's take this medicine and wait 20 minutes, and I know how to standardize 20 minutes, which is... Three Ave Marias, four Ave Marias may actually be time travel. SPEAKER_03: That's fascinating. SPEAKER_06: It may appear one way, and it in fact could be a totally different way. SPEAKER_05: It suggests that in order to time travel, you have to somehow... God, it's like we don't even have the language to be able to understand what they were doing and how effective it was. SPEAKER_06: There's a phrase, the past is a foreign country. SPEAKER_10: we need to learn the language of the doctors of that time we need to kind of be a little bit less dismissive and learn a little bit more you know stuff from them I learned a bit of humility this way SPEAKER_06: But here's the reason why this is so confusing to me.So 1,100 years is a crazy long time for humans.And for bacteria, that's like an exponentially crazy long time.So how is it that something that this man, Bald, was doing to these bacteria then, like it's not even the same bacteria.How could that even work? SPEAKER_09: That's an awesome question.So one thing we've got to think about is why did these medicines drop out of use?And maybe it's because when they were used, the bacteria evolved resistance.But now, a thousand years later... When these medicines have not been used, you would expect that resistance to be lost. SPEAKER_06: This is something that Maren McKenna mentioned to Soren and I, that sometimes when you take a drug out of circulation... Sometimes resistance will decline. SPEAKER_08: That doesn't always work, but sometimes resistance does decline.So if we had been using this compound through the ensuing thousand years, then maybe it wouldn't work. SPEAKER_03: So there's an interesting discovery there, like that what worked once... and then was resisted, you give it a rest, and it can work again, and it will be resisted.And you put it to rest, and if you had enough different, if you could go to different places in the different paths, to go to China, where they now got all these people studying Chinese cures and Arab cures, you could come up with a cure. with a rich historical cocktail of armamentariums that will work if you bring them in, take them out, bring them in, take them out.And the whole world, the whole world of the past then becomes the fruit of your future, sort of. SPEAKER_17: So it's also like now I have a suddenly an image that it's possible that... This is Soren Wheeler, by the way, in conversation with Maren McKenna Latif.That a thousand years ago, these folks went through what we went through with penicillin in that this guy wrote something in the book and it's actually called The Best Medicine.He probably got on the cover of whatever their version of time was. SPEAKER_08: He got their Nobel Prize. SPEAKER_17: And everybody celebrated and then... years later styes were coming back and the garlic wine didn't work anymore and they stopped using it and it got put away and then here we are and we discover it and it's been put away long enough that like then now i'm thinking about future some future civilization digs up an old medical textbook that was in some dusty whatever and discovers penicillin and it works Did I lose you on that, Mary? SPEAKER_08: No, no, I'm still with you.I'm just, I don't know.It just seemed like such a great hypothetical construction.I just didn't really know what I could add to it. SPEAKER_07: Sorry I took over. SPEAKER_06: Thank you for listening.It's actually, it's been almost a full decade since we aired this episode.And since then, Christina and Freya have published several papers to show how this concoction works and why.Apparently, there's not just one, but multiple key ingredients at work in their ancient salve.They've also been collaborating with PhD students to create a recipe that can be turned into an actual medicine available to folks like you and me. But science is a slow process, and things like logistics and funding just make it even slower.They are pretty hopeful that they will get something to us before the next 1,000 years pass by.
