1 00:00:03,160 --> 00:00:06,519 Speaker 1: You're listening to Part Time Genius, the production of Kaleidoscope 2 00:00:06,720 --> 00:00:09,320 Speaker 1: and iHeartRadio. 3 00:00:12,080 --> 00:00:12,840 Speaker 2: Guess what Mango? 4 00:00:13,039 --> 00:00:14,000 Speaker 1: What's that will? 5 00:00:14,160 --> 00:00:16,919 Speaker 2: It's day four of our countdown of the twenty five 6 00:00:17,000 --> 00:00:20,400 Speaker 2: greatest science ideas from the past twenty five years. Can 7 00:00:20,440 --> 00:00:23,680 Speaker 2: you believe it? Just a few short days ago it 8 00:00:23,840 --> 00:00:26,880 Speaker 2: was day one of our twenty five greatest science ideas 9 00:00:26,880 --> 00:00:28,040 Speaker 2: in the past twenty five years. 10 00:00:28,080 --> 00:00:30,160 Speaker 1: I'm pretty sure you know you're doing something right when 11 00:00:30,160 --> 00:00:33,120 Speaker 1: you've got four sequels. What do you mean by that, Well, 12 00:00:33,360 --> 00:00:36,600 Speaker 1: George Lucas stars Star Wars basically with the fourth film, right. 13 00:00:37,040 --> 00:00:39,959 Speaker 1: Henry the fourth was such an interesting king that Shakespeare 14 00:00:40,000 --> 00:00:41,840 Speaker 1: wrote a play about him. But you didn't even bother 15 00:00:41,960 --> 00:00:44,920 Speaker 1: with Henry the Third, No not worthy and Rush Hour 16 00:00:45,000 --> 00:00:47,120 Speaker 1: four was so good at made Toy Story two seem 17 00:00:47,200 --> 00:00:49,279 Speaker 1: like Spider Man three. 18 00:00:49,680 --> 00:00:51,480 Speaker 2: I'm pretty sure you're just saying things now. 19 00:00:51,880 --> 00:00:54,920 Speaker 1: Yeah, you're right, but maybe you should just get into 20 00:00:54,920 --> 00:00:58,240 Speaker 1: the episode. Today we are covering ideas eight through five, 21 00:00:58,440 --> 00:01:00,200 Speaker 1: and if you want to know what makes us try 22 00:01:00,240 --> 00:01:03,840 Speaker 1: to various sounds so good, how a HeLa monster is 23 00:01:03,960 --> 00:01:07,960 Speaker 1: helping the world, and why a single injection might help 24 00:01:08,040 --> 00:01:11,640 Speaker 1: paralyze people walk again. You're gonna love this one. Let's 25 00:01:11,680 --> 00:01:12,039 Speaker 1: dive in. 26 00:01:33,880 --> 00:01:36,640 Speaker 2: Hey, their podcast listeners, welcome to Part Time Genius. I'm 27 00:01:36,640 --> 00:01:38,759 Speaker 2: Will Pearson, and of course I'm here with my friend 28 00:01:38,760 --> 00:01:41,679 Speaker 2: Mangesh hot Ticketter and over there in the booth gazing 29 00:01:41,720 --> 00:01:44,560 Speaker 2: wistfully at a portrait of David Dukovney. I don't know 30 00:01:44,600 --> 00:01:47,760 Speaker 2: where he got this thing, but it's a it's an 31 00:01:47,760 --> 00:01:50,760 Speaker 2: interesting portrait. It's our PALIN producer, Dylan Fagan. I mean, 32 00:01:50,960 --> 00:01:53,040 Speaker 2: I can't tell if this has anything to do with 33 00:01:53,080 --> 00:01:54,280 Speaker 2: today's episode. 34 00:01:54,120 --> 00:01:55,800 Speaker 1: They just like slax Files apparently. 35 00:01:55,880 --> 00:01:57,600 Speaker 2: Oh okay, well enjoy that, Dylan. 36 00:01:58,320 --> 00:02:01,360 Speaker 1: But speaking of fun, you your podcast listening life will 37 00:02:01,400 --> 00:02:03,360 Speaker 1: be a lot more fun if you're subscribed to Part 38 00:02:03,400 --> 00:02:05,800 Speaker 1: Time Genius on whatever app you use. And you can 39 00:02:05,840 --> 00:02:08,280 Speaker 1: make sure our lives are more fun by leaving us 40 00:02:08,320 --> 00:02:08,959 Speaker 1: a nice review. 41 00:02:09,040 --> 00:02:11,480 Speaker 2: We really appreciate everyone who takes the time to do that. 42 00:02:11,600 --> 00:02:13,920 Speaker 2: But all right, well let's get back to the countdown. 43 00:02:16,040 --> 00:02:18,600 Speaker 2: So one day in the early two thousands, a man 44 00:02:18,680 --> 00:02:22,160 Speaker 2: named Kai Ching Lee was strolling down in Oregon beach right, 45 00:02:22,520 --> 00:02:26,760 Speaker 2: and Lee is an engineering professor at Oregon State University, 46 00:02:26,800 --> 00:02:30,480 Speaker 2: and he was just enjoying his walk washing the Pacific Ocean, 47 00:02:31,000 --> 00:02:33,880 Speaker 2: just waves roll in and now, and suddenly he noticed 48 00:02:33,919 --> 00:02:38,200 Speaker 2: something along the coast. There were hundreds of muscles clinging 49 00:02:38,200 --> 00:02:42,200 Speaker 2: to rocks, and Lee was impressed with their strength. No 50 00:02:42,240 --> 00:02:44,440 Speaker 2: matter how violent the waves were, no matter how strong 51 00:02:44,480 --> 00:02:47,000 Speaker 2: the pull of the tide was, the muscles just stayed 52 00:02:47,120 --> 00:02:50,080 Speaker 2: in place there and when you actually tried pulling one away, 53 00:02:50,760 --> 00:02:55,040 Speaker 2: it wouldn't budge. And that got Lee thinking about plywood. 54 00:02:55,160 --> 00:02:57,760 Speaker 2: M had he also been to an Ikea recently that 55 00:02:57,840 --> 00:02:58,080 Speaker 2: might have. 56 00:02:58,280 --> 00:03:00,639 Speaker 1: I mean, maybe I don't know, but I do know 57 00:03:00,760 --> 00:03:04,280 Speaker 1: that plywood is everywhere, not just furniture and cabinets, but 58 00:03:04,280 --> 00:03:07,760 Speaker 1: also walls, boats, fencing, toys, and for good reason. Like 59 00:03:07,960 --> 00:03:11,800 Speaker 1: plywood is super affordable because instead of a single solid 60 00:03:11,880 --> 00:03:14,720 Speaker 1: chunk of wood, it's made from thin layers glued together 61 00:03:14,800 --> 00:03:17,640 Speaker 1: into a slab. But it turns out the glue that 62 00:03:17,720 --> 00:03:21,040 Speaker 1: holds the plywood together is really kind of nasty. It's 63 00:03:21,120 --> 00:03:24,120 Speaker 1: often made with formaldehyde and other chemicals that you don't 64 00:03:24,120 --> 00:03:26,840 Speaker 1: want to breathe in, and in fact, there's research suggesting 65 00:03:26,919 --> 00:03:30,040 Speaker 1: that people who work in plywood manufacturing plants are at 66 00:03:30,160 --> 00:03:34,280 Speaker 1: increased risk of developing leukemia and other cancers. And that's 67 00:03:34,320 --> 00:03:36,760 Speaker 1: what Kaiching. Lee was thinking about that day on the beach, 68 00:03:37,120 --> 00:03:40,200 Speaker 1: how to make a better, safer plywood glue. 69 00:03:39,960 --> 00:03:42,200 Speaker 2: And if muscles can stick themselves to rocks, maybe they 70 00:03:42,200 --> 00:03:43,640 Speaker 2: could stick wood together too. 71 00:03:44,040 --> 00:03:47,360 Speaker 1: Yeah, so muscles. Natural adhesive has two big advantages over 72 00:03:47,400 --> 00:03:51,119 Speaker 1: traditional plywood glues. First of all, it's non toxic, and secondly, 73 00:03:51,200 --> 00:03:54,680 Speaker 1: it's waterproof. So if you've ever gotten plywood furniture wet, 74 00:03:54,960 --> 00:03:57,040 Speaker 1: you know what a pain it can be because if 75 00:03:57,040 --> 00:04:00,200 Speaker 1: the water isn't dried quickly, the wood layers can start peeling. 76 00:04:00,320 --> 00:04:03,360 Speaker 1: This is a known problem with industrial adhesives, like many 77 00:04:03,400 --> 00:04:05,640 Speaker 1: of them lose their stickiness in the presence of water, 78 00:04:05,760 --> 00:04:07,760 Speaker 1: but not muscle glue. 79 00:04:07,920 --> 00:04:10,240 Speaker 2: Right, but how do you get glue out of a muscle? 80 00:04:10,640 --> 00:04:13,160 Speaker 1: Yeah, it's a good question. So Lee realized right away 81 00:04:13,200 --> 00:04:16,600 Speaker 1: that would be difficult and expensive, not to mention unpleasant 82 00:04:16,600 --> 00:04:19,200 Speaker 1: for the muscles. But he headed to his lab to 83 00:04:19,200 --> 00:04:21,360 Speaker 1: see if he could cook up a synthetic version of 84 00:04:21,400 --> 00:04:24,599 Speaker 1: the muscle glue, and one day, while he was eating 85 00:04:24,600 --> 00:04:29,039 Speaker 1: his lunch, he had another light bulb moment. He realized, soybeans, 86 00:04:29,600 --> 00:04:31,760 Speaker 1: I love how this daily life was just handing him 87 00:04:31,760 --> 00:04:34,240 Speaker 1: the scientific answers that he needed. I know, it's just 88 00:04:34,320 --> 00:04:37,520 Speaker 1: inspiration is everywhere anyway. People have been making adhesis from 89 00:04:37,600 --> 00:04:41,920 Speaker 1: soy for decades. The problem is, soy based glues tend 90 00:04:41,920 --> 00:04:45,640 Speaker 1: to be weak and they're not waterproof. But Lee knew 91 00:04:45,680 --> 00:04:49,160 Speaker 1: that soybean, flower and muscle glue were made from similar 92 00:04:49,200 --> 00:04:52,279 Speaker 1: makeup of proteins and amino acids, and he wondered, what 93 00:04:52,360 --> 00:04:55,359 Speaker 1: if I altered the chemical profile of soybean glue to 94 00:04:55,839 --> 00:04:58,360 Speaker 1: make it more like the kind made by muscles. So, 95 00:04:58,560 --> 00:05:00,960 Speaker 1: with the help of a grant from the US, Lee 96 00:05:01,000 --> 00:05:04,520 Speaker 1: started tinkering with soy's chemical makeup, and by modifying the 97 00:05:04,520 --> 00:05:07,960 Speaker 1: amino acids in the bean, he successfully created an adhesive 98 00:05:08,040 --> 00:05:11,240 Speaker 1: that was just his waterproof and just as strong as 99 00:05:11,240 --> 00:05:14,000 Speaker 1: the glue made by muscles. In fact, the soybean based 100 00:05:14,000 --> 00:05:17,080 Speaker 1: glue was twice as sticky as hot glue, three times 101 00:05:17,080 --> 00:05:20,200 Speaker 1: stronger than Elmer's glue, and had about the same adhesive 102 00:05:20,320 --> 00:05:22,040 Speaker 1: power as contact cement. 103 00:05:22,440 --> 00:05:25,600 Speaker 2: And has this revolutionized the plywood industry or what? Yeah? 104 00:05:25,640 --> 00:05:29,120 Speaker 1: So it's definitely changed things. Like Lee presented his discovery 105 00:05:29,160 --> 00:05:32,800 Speaker 1: to Columbia Forest Products. They're a major plywood manufacturer, and 106 00:05:32,880 --> 00:05:36,400 Speaker 1: they quickly signed on. So fast forward to today, the 107 00:05:36,440 --> 00:05:40,040 Speaker 1: company has converted all of its factories from formaldehyde glues 108 00:05:40,279 --> 00:05:43,240 Speaker 1: to soy, and pollution rates that some of these plants 109 00:05:43,240 --> 00:05:46,839 Speaker 1: have dropped by as much as ninety percent. Wow, isn't 110 00:05:46,839 --> 00:05:49,400 Speaker 1: that insane? And other companies have joined them too, so 111 00:05:49,480 --> 00:05:52,880 Speaker 1: today soy based plywood is an option at most hardware 112 00:05:52,920 --> 00:05:56,320 Speaker 1: and home improvement stores. Other big companies like Ikea and 113 00:05:56,400 --> 00:05:59,040 Speaker 1: General Motors now use soy for some of their plywood 114 00:05:59,080 --> 00:06:03,839 Speaker 1: products because it's safer, stronger, and better for the planet. Anyway, 115 00:06:03,880 --> 00:06:07,760 Speaker 1: in honor of Lee's incredible discovery that changed home DIY forever, 116 00:06:07,800 --> 00:06:10,559 Speaker 1: we're running a contest on Instagram today. We're giving away 117 00:06:10,880 --> 00:06:13,840 Speaker 1: a home Depot. Gifts are to the get, and our 118 00:06:13,920 --> 00:06:16,160 Speaker 1: lawyers want to make it very very clear that this 119 00:06:16,279 --> 00:06:18,600 Speaker 1: is no way sponsored by Home Depot. But head over 120 00:06:18,640 --> 00:06:20,960 Speaker 1: to Instagram at part time Genius to get all the 121 00:06:21,000 --> 00:06:22,280 Speaker 1: details in enter. 122 00:06:24,000 --> 00:06:25,960 Speaker 2: All right, So I'd like to dedicate this next one 123 00:06:25,960 --> 00:06:28,599 Speaker 2: to all the violinists who have dreamed of owning a 124 00:06:28,640 --> 00:06:32,880 Speaker 2: Stratavius violin but can't stomach the instruments two million dollar 125 00:06:32,960 --> 00:06:35,000 Speaker 2: price tag. They're just not that serious about it, magat 126 00:06:35,200 --> 00:06:37,720 Speaker 2: they don't want to spend the two million, so here 127 00:06:37,760 --> 00:06:38,800 Speaker 2: we Yeah. 128 00:06:38,760 --> 00:06:42,080 Speaker 1: I would love to know how many professional violinists listen 129 00:06:42,120 --> 00:06:45,040 Speaker 1: to the show. But two million dollars is obviously a 130 00:06:45,080 --> 00:06:47,320 Speaker 1: steep price tag for a three hundred year old violin 131 00:06:47,480 --> 00:06:50,240 Speaker 1: that you're probably too scared to play anyway. 132 00:06:50,480 --> 00:06:54,440 Speaker 2: Indeed, but thanks to research from Swiss arborist Franz Schwartz, 133 00:06:54,720 --> 00:06:57,760 Speaker 2: there's now a cheaper alternative. And while the new instruments 134 00:06:57,800 --> 00:07:00,480 Speaker 2: don't carry the distinction of having been crafted by Italy's 135 00:07:00,480 --> 00:07:04,080 Speaker 2: most revered violin maker, they do boast a tone quality 136 00:07:04,080 --> 00:07:07,000 Speaker 2: that many experts consider to be just as good and 137 00:07:07,080 --> 00:07:10,080 Speaker 2: in some cases may be better, a claim that might 138 00:07:10,120 --> 00:07:13,280 Speaker 2: seem stunning enough, but the real shock is who's responsible 139 00:07:13,320 --> 00:07:15,800 Speaker 2: for the superior sound? Are you ready for this? 140 00:07:16,280 --> 00:07:21,760 Speaker 1: It's fungus like Geseppe fungus, the famous Italian violin maker. Nope, nope, 141 00:07:21,840 --> 00:07:25,680 Speaker 1: actual fungus that infested the wood used to make the instruments. 142 00:07:25,920 --> 00:07:28,480 Speaker 1: It is totally bizarre because in most cases, a fungal 143 00:07:28,520 --> 00:07:31,400 Speaker 1: attack destroys wood cell walls and it results in this 144 00:07:31,480 --> 00:07:34,400 Speaker 1: kind of loose soft wood that doesn't sound very pleasant 145 00:07:34,400 --> 00:07:37,360 Speaker 1: if it's made into an instrument. But at Schwartz discovered 146 00:07:37,400 --> 00:07:40,360 Speaker 1: in the late two thousands. There are rare cases where 147 00:07:40,360 --> 00:07:43,440 Speaker 1: fungal infections have a milder effect on the wood's density 148 00:07:43,680 --> 00:07:46,560 Speaker 1: and actually make it sound better. So what happens is 149 00:07:46,600 --> 00:07:49,240 Speaker 1: they thin out the wood cells structure just enough to 150 00:07:49,280 --> 00:07:52,960 Speaker 1: improve its acoustic properties. And so how did he figure 151 00:07:53,000 --> 00:07:56,080 Speaker 1: this out? Exactly? Like do arboris just go around knocking 152 00:07:56,120 --> 00:07:58,320 Speaker 1: on trees to see what sounds they make? 153 00:07:58,440 --> 00:08:00,640 Speaker 2: I'm sure that's not how they describe, but it is 154 00:08:00,800 --> 00:08:03,640 Speaker 2: kind of like that. Scientists really do bounce sound waves 155 00:08:03,640 --> 00:08:07,400 Speaker 2: off of trees to gauge their health. The funkier the echo, 156 00:08:07,560 --> 00:08:10,760 Speaker 2: the more widespread the wood rot. And so Franz Schwartz 157 00:08:11,000 --> 00:08:13,560 Speaker 2: was using this method himself when he hatched the idea 158 00:08:13,680 --> 00:08:17,040 Speaker 2: for his fungal violin. He wondered how gentler kinds of 159 00:08:17,120 --> 00:08:19,720 Speaker 2: fungus might affect the sound of a wooden instrument, so 160 00:08:20,080 --> 00:08:24,160 Speaker 2: he partnered with Swiss violin maker Michael Ronheimer to find out. 161 00:08:24,720 --> 00:08:27,720 Speaker 2: They selected two different species of wood eating fungi for 162 00:08:27,800 --> 00:08:30,080 Speaker 2: the job. And while I won't bother to pronounce their 163 00:08:30,120 --> 00:08:33,880 Speaker 2: scientific names, I can tell you their nicknames their Rusty 164 00:08:33,960 --> 00:08:37,520 Speaker 2: crust and dead mule's fingers. So those are both. 165 00:08:37,320 --> 00:08:39,720 Speaker 1: Pretty good I'm not sure which is grosser, but I 166 00:08:39,720 --> 00:08:41,280 Speaker 1: think i'd go with rusty crust. 167 00:08:41,400 --> 00:08:44,880 Speaker 2: That is the right answer. But anyway, the top plate 168 00:08:44,920 --> 00:08:48,359 Speaker 2: of the violin, which was made of spruce, was inoculated 169 00:08:48,400 --> 00:08:51,760 Speaker 2: with rusty crust, and on the bottom, the sycamore plate 170 00:08:51,880 --> 00:08:55,400 Speaker 2: was treated with dead mule's fingers. Both plates were submerged 171 00:08:55,440 --> 00:08:58,240 Speaker 2: in a box of water to stimulate the fungui's growth, 172 00:08:58,280 --> 00:09:01,240 Speaker 2: and a few months later, after killing off the spores, 173 00:09:01,600 --> 00:09:04,640 Speaker 2: Ronheimer put the two halves together to create the world's 174 00:09:04,720 --> 00:09:08,720 Speaker 2: first bio violin. So Schwartz was blown away by the 175 00:09:08,720 --> 00:09:12,600 Speaker 2: instrument's sound, which he described as warmer and rounder than 176 00:09:12,600 --> 00:09:15,520 Speaker 2: that of a conventional violin, and he was so pleased 177 00:09:15,520 --> 00:09:17,960 Speaker 2: with it that he decided to stage a blind sound 178 00:09:17,960 --> 00:09:21,440 Speaker 2: test at an annual forestry conference in Germany, so on 179 00:09:21,520 --> 00:09:24,760 Speaker 2: September first, two thousand and nine a jury of acoustics 180 00:09:24,800 --> 00:09:29,160 Speaker 2: experts and conference attendees. They listened carefully as British violinist 181 00:09:29,280 --> 00:09:33,120 Speaker 2: Matthew Trussler played five different instruments from behind the curtain. 182 00:09:33,800 --> 00:09:36,400 Speaker 2: Four of the violins were made by Ronheimer, two of 183 00:09:36,440 --> 00:09:39,200 Speaker 2: them with fungus treated wood and the other two with 184 00:09:39,400 --> 00:09:43,000 Speaker 2: untreated wood. From the same trees, but the fifth instrument 185 00:09:43,120 --> 00:09:47,199 Speaker 2: came from Trustler's own collection, a violin made by Antonio 186 00:09:47,280 --> 00:09:51,040 Speaker 2: Strativeris himself way back in seventeen eleven. 187 00:09:51,679 --> 00:09:54,920 Speaker 1: So I guess the goal was to identify which one 188 00:09:55,160 --> 00:09:57,240 Speaker 1: was the true strat in the mix. 189 00:09:57,360 --> 00:10:00,079 Speaker 2: That's exactly right. So attendees were asked to rank the 190 00:10:00,120 --> 00:10:02,800 Speaker 2: sound of each instrument they heard and to guess which 191 00:10:02,800 --> 00:10:05,440 Speaker 2: one of them was over three hundred years old. Schwartz 192 00:10:05,520 --> 00:10:07,920 Speaker 2: later admitted that as good as they sounded, he never 193 00:10:07,960 --> 00:10:10,400 Speaker 2: expected one of the fungal violins to be confused for 194 00:10:10,480 --> 00:10:13,560 Speaker 2: a multi million dollar instrument. But in the end, that 195 00:10:13,640 --> 00:10:16,319 Speaker 2: is exactly what happened. Out of more than one hundred 196 00:10:16,360 --> 00:10:20,080 Speaker 2: and eighty attendees, one hundred and thirteen of them thought 197 00:10:20,080 --> 00:10:22,960 Speaker 2: that one of Ronheimer's violins, which had been covered with 198 00:10:23,000 --> 00:10:26,320 Speaker 2: fung gui for nine months, was produced by stratuv Areas. 199 00:10:26,360 --> 00:10:27,920 Speaker 1: So it wasn't It wasn't even close. 200 00:10:28,080 --> 00:10:30,600 Speaker 2: No, I mean, the real strat came in a distant second, 201 00:10:30,880 --> 00:10:33,920 Speaker 2: but the other fungus violin claiming third place, and the 202 00:10:33,960 --> 00:10:37,000 Speaker 2: two untreated instruments pulling up the rear so like it 203 00:10:37,040 --> 00:10:39,760 Speaker 2: really does show the difference that it made I mean. 204 00:10:39,840 --> 00:10:42,600 Speaker 1: I get that, like a fungus could change the wood 205 00:10:42,640 --> 00:10:46,040 Speaker 1: and the sound of a violin, but like, why are 206 00:10:46,080 --> 00:10:47,800 Speaker 1: they comparable to stratavarius. 207 00:10:48,200 --> 00:10:50,400 Speaker 2: It's a good question, and honestly, no one can really 208 00:10:50,480 --> 00:10:52,600 Speaker 2: say for sure why is violin sound as good as 209 00:10:52,640 --> 00:10:54,560 Speaker 2: they do. The best guess is that it's due to 210 00:10:54,600 --> 00:10:57,760 Speaker 2: the weather in Italy during his lifetime, so strata areas 211 00:10:57,760 --> 00:10:59,960 Speaker 2: happened to live through what people knew as central yuar 212 00:11:00,040 --> 00:11:03,120 Speaker 2: rops little ice age. This happened in the seventeenth century, 213 00:11:03,440 --> 00:11:06,760 Speaker 2: and it brought long winters and cool summers to the region. 214 00:11:07,080 --> 00:11:10,120 Speaker 2: So the unusually chilly temperatures would have slowed the cell 215 00:11:10,160 --> 00:11:12,959 Speaker 2: growth of the local trees there, causing their wood to 216 00:11:13,000 --> 00:11:17,000 Speaker 2: develop more slowly and uniformly, which was the perfect recipe 217 00:11:17,040 --> 00:11:20,600 Speaker 2: for producing wood with stellar acoustics. So, according to Schwartz, 218 00:11:20,600 --> 00:11:23,199 Speaker 2: the fungi treatment he used was able to recreate that 219 00:11:23,240 --> 00:11:24,400 Speaker 2: same ideal structure. 220 00:11:24,600 --> 00:11:27,520 Speaker 1: That's really cool. But if a fungus violin produces a 221 00:11:27,640 --> 00:11:30,319 Speaker 1: richer sound, why don't they do that for all violins now? 222 00:11:30,440 --> 00:11:33,440 Speaker 2: Well, partly because not every violin needs the same tonal 223 00:11:33,520 --> 00:11:36,880 Speaker 2: quality as the strativarius. Like it's nice to have different options, 224 00:11:37,200 --> 00:11:39,400 Speaker 2: but the main reason is that Schwartz and his colleagues 225 00:11:39,400 --> 00:11:42,000 Speaker 2: are still working out the details on how you'd actually 226 00:11:42,040 --> 00:11:44,680 Speaker 2: mass produce these. Once they do, the plan is to 227 00:11:44,679 --> 00:11:47,560 Speaker 2: sell the instruments for about thirty thousand dollars each, which 228 00:11:47,880 --> 00:11:50,040 Speaker 2: sounds like a lot, but it's actually about what you'd 229 00:11:50,080 --> 00:11:52,720 Speaker 2: pay for other high quality violins. 230 00:11:52,360 --> 00:11:53,920 Speaker 1: And a lot less than two million dollars. 231 00:11:53,960 --> 00:11:55,400 Speaker 2: Definitely, you're good at math. 232 00:11:57,240 --> 00:11:59,520 Speaker 1: We've got a pause for a quick break, but we'll 233 00:11:59,559 --> 00:12:18,480 Speaker 1: be back more great science ideas right after. Welcome back 234 00:12:18,480 --> 00:12:21,400 Speaker 1: to part time genius listeners, and we are counting down 235 00:12:21,440 --> 00:12:25,880 Speaker 1: to number Okay, So I'm not going to beat around 236 00:12:25,880 --> 00:12:29,720 Speaker 1: the bush on this one. This research totally blew my mind. 237 00:12:29,960 --> 00:12:33,800 Speaker 1: So scientists and Northwestern University have developed a new treatment 238 00:12:33,880 --> 00:12:37,600 Speaker 1: for spinal cord injuries that allowed paralyzed mice to walk 239 00:12:37,679 --> 00:12:42,080 Speaker 1: again after a single injection. Not only that, the treatment 240 00:12:42,120 --> 00:12:45,280 Speaker 1: has loads of other applications, potentially impacting the way we 241 00:12:45,320 --> 00:12:50,600 Speaker 1: treat everything from bone loss to neurodegenerative diseases like Alzheimer's. 242 00:12:50,920 --> 00:12:52,400 Speaker 2: I can't I've never heard of this. I mean, it 243 00:12:52,440 --> 00:12:54,560 Speaker 2: sounds like a real life cure. All yeah, I mean, 244 00:12:54,559 --> 00:12:57,439 Speaker 2: it's still early days. From the research perspective, the team's 245 00:12:57,480 --> 00:12:59,840 Speaker 2: big breakthrough was only back in twenty twenty one, but 246 00:13:00,000 --> 00:13:03,679 Speaker 2: so far the data is really incredible and promising. So 247 00:13:04,080 --> 00:13:06,120 Speaker 2: just to give a little background on why this is 248 00:13:06,120 --> 00:13:09,040 Speaker 2: such a big deal, They're currently about three hundred thousand 249 00:13:09,040 --> 00:13:12,280 Speaker 2: people living with a spinal cord injury in the US alone, 250 00:13:12,720 --> 00:13:15,440 Speaker 2: and in the most severe cases, less than three percent 251 00:13:15,440 --> 00:13:18,960 Speaker 2: of them will ever recover any basic physical functions. The 252 00:13:18,960 --> 00:13:21,080 Speaker 2: reason for that is that the neurons and their spinal 253 00:13:21,120 --> 00:13:25,079 Speaker 2: cords have been completely severed, and thus far as scientists 254 00:13:25,080 --> 00:13:28,280 Speaker 2: haven't been able to find therapeutics that can successfully trigger 255 00:13:28,400 --> 00:13:31,960 Speaker 2: spinal cord regeneration. But that changed with the study from 256 00:13:32,000 --> 00:13:36,280 Speaker 2: Northwestern University. So researchers were able to reverse paralysis and 257 00:13:36,400 --> 00:13:40,720 Speaker 2: mice by injecting them with something they called dancing molecules. 258 00:13:41,200 --> 00:13:43,400 Speaker 2: I've actually never heard of that either, so I'm curious 259 00:13:43,400 --> 00:13:46,360 Speaker 2: that are the molecules themselves dancing or is it that 260 00:13:46,800 --> 00:13:49,520 Speaker 2: they can restore the mouse's ability to dance? What are 261 00:13:49,520 --> 00:13:50,240 Speaker 2: we referring to? 262 00:13:50,440 --> 00:13:52,720 Speaker 1: Yeah, so no word on whether the mice can dance 263 00:13:52,800 --> 00:13:55,520 Speaker 1: before or after the treatment, but the molecules that were 264 00:13:55,520 --> 00:13:59,960 Speaker 1: injected absolutely can dance. So after being injected as a liquid, 265 00:14:00,080 --> 00:14:04,760 Speaker 1: the molecules coalesced to form tiny synthetic nanofibers that surround 266 00:14:04,880 --> 00:14:08,480 Speaker 1: the spinal cord. And the fibers were composed of tens 267 00:14:08,520 --> 00:14:11,200 Speaker 1: of hundreds of thousands of molecules, and the researchers found 268 00:14:11,240 --> 00:14:14,120 Speaker 1: that by changing their chemical structure, they could control the 269 00:14:14,160 --> 00:14:17,120 Speaker 1: molecule's collective motion. This allowed them to fine tune the 270 00:14:17,120 --> 00:14:20,720 Speaker 1: synthetic molecules movements, speeding them up to match the motion 271 00:14:20,840 --> 00:14:24,360 Speaker 1: of biological molecules within the spinal cord. It turned out 272 00:14:24,400 --> 00:14:27,520 Speaker 1: that the most hyperactive molecules, the ones that were dancing 273 00:14:27,560 --> 00:14:31,160 Speaker 1: the most, were able to connect more effectively with receptors 274 00:14:31,200 --> 00:14:32,800 Speaker 1: in neurons and other cells. 275 00:14:33,240 --> 00:14:36,040 Speaker 2: So once the molecules made that connection, they were able 276 00:14:36,080 --> 00:14:39,920 Speaker 2: to like tell the cells to repair the damage neurons. 277 00:14:40,040 --> 00:14:43,880 Speaker 1: Yeah, So the dancing molecules triggered to bioactive signals. The 278 00:14:44,120 --> 00:14:47,560 Speaker 1: first prompted the tails of the neurons to regenerate and 279 00:14:47,600 --> 00:14:50,600 Speaker 1: that effectively restored communication between the body and the brain, 280 00:14:50,960 --> 00:14:54,840 Speaker 1: and the second signal promoted the regrowth of lost blood 281 00:14:54,880 --> 00:14:57,520 Speaker 1: cells that feed the neurons and other cells related to 282 00:14:57,520 --> 00:15:00,560 Speaker 1: tissue repair, and the result of this intervention was that 283 00:15:00,920 --> 00:15:04,560 Speaker 1: after just four weeks, these paralyzed mice could regain the 284 00:15:04,600 --> 00:15:06,720 Speaker 1: ability to walk, which is just stunning. 285 00:15:06,840 --> 00:15:08,840 Speaker 2: Yeah, and it's also kind of a testament to the 286 00:15:08,880 --> 00:15:10,560 Speaker 2: power of dance if you think about it, because it 287 00:15:10,600 --> 00:15:12,400 Speaker 2: sounds like the approach didn't work so well when they 288 00:15:12,480 --> 00:15:15,080 Speaker 2: tried it with more sluggish molecules. 289 00:15:15,280 --> 00:15:18,280 Speaker 1: Yeah, that souped up molecular motion really was the key 290 00:15:18,320 --> 00:15:21,040 Speaker 1: factor in all of this. The cells and receptors within 291 00:15:21,080 --> 00:15:23,960 Speaker 1: the body are constantly moving, so once the team was 292 00:15:24,000 --> 00:15:26,840 Speaker 1: able to match that speed or vibration, the fast moving 293 00:15:26,880 --> 00:15:31,040 Speaker 1: molecules encountered the receptors much more often, and that allowed 294 00:15:31,040 --> 00:15:33,720 Speaker 1: them to send their signals again and again. The breakthrough 295 00:15:33,760 --> 00:15:37,920 Speaker 1: therapy actually has obvious implications for improving the spinal injuries 296 00:15:37,920 --> 00:15:41,280 Speaker 1: of both humans and animals, but there's reasons to hope 297 00:15:41,320 --> 00:15:44,560 Speaker 1: that the underlying discovery could also be used in other treatments, 298 00:15:44,600 --> 00:15:47,120 Speaker 1: as we allude to before. According to the studies, lead 299 00:15:47,160 --> 00:15:51,160 Speaker 1: researchers Samuel Stupp quote, the central nervous system tissues we 300 00:15:51,160 --> 00:15:54,920 Speaker 1: have successfully regenerated in the injured spinal cord are similar 301 00:15:54,920 --> 00:15:58,680 Speaker 1: to those in the brain affected by stroke and neurodegenerative 302 00:15:58,720 --> 00:16:03,880 Speaker 1: diseases such as als, Parkinson's and Alzheimer's. Beyond that, our 303 00:16:03,920 --> 00:16:07,440 Speaker 1: fundamental discovery about controlling the motion of molecular assemblies to 304 00:16:07,600 --> 00:16:12,840 Speaker 1: enhance cells signaling could be applied universally across biomedical targets. 305 00:16:13,240 --> 00:16:15,680 Speaker 2: Okay, so they're thinking they could fine tune molecules to 306 00:16:15,760 --> 00:16:18,520 Speaker 2: match the motion of other damage cells, not just the 307 00:16:18,520 --> 00:16:20,040 Speaker 2: ones in the spinal cord exactly. 308 00:16:20,120 --> 00:16:22,480 Speaker 1: And the most amazing part is they've already done it. 309 00:16:22,560 --> 00:16:25,600 Speaker 1: So just last year, the team from Northwestern applied their 310 00:16:25,640 --> 00:16:30,040 Speaker 1: strategy to damaged human cartilage cells and they found some success. Now, 311 00:16:30,200 --> 00:16:33,040 Speaker 1: normally there's no way for humans to regenerate the tissues 312 00:16:33,080 --> 00:16:36,240 Speaker 1: in our joints once we reach adulthood. So if you 313 00:16:36,280 --> 00:16:39,080 Speaker 1: have a disease in which cartilage breaks down over time, 314 00:16:39,320 --> 00:16:41,320 Speaker 1: you eventually get to a point where the bone is 315 00:16:41,360 --> 00:16:44,720 Speaker 1: grinding against the bone with no cushion between them. And 316 00:16:44,800 --> 00:16:48,320 Speaker 1: currently the only treatment for this is joint replacement surgery, 317 00:16:48,320 --> 00:16:52,680 Speaker 1: which is extremely invasive and also very expensive. But once again, 318 00:16:52,960 --> 00:16:55,520 Speaker 1: the team here has found a much better solution. So 319 00:16:55,960 --> 00:16:59,560 Speaker 1: using their injectable therapy, they were able to spur cartilage 320 00:16:59,600 --> 00:17:03,120 Speaker 1: regeneration and damaged cells within just a matter of days, 321 00:17:03,480 --> 00:17:05,960 Speaker 1: and once again it was the molecules dancing that triggered 322 00:17:06,000 --> 00:17:09,280 Speaker 1: the process. So building on that second success, the team's 323 00:17:09,320 --> 00:17:12,840 Speaker 1: next goal is to test the therapy's effectiveness at regenerating 324 00:17:12,880 --> 00:17:17,800 Speaker 1: bone and from there the sky's limit because, as Stuff explained, quote, 325 00:17:18,040 --> 00:17:20,560 Speaker 1: now we have observed the effects in two cell types 326 00:17:20,600 --> 00:17:24,080 Speaker 1: that are completely disconnected from one another, cartilage cells in 327 00:17:24,119 --> 00:17:26,600 Speaker 1: our joints and neurons in our brain and spinal cord. 328 00:17:27,000 --> 00:17:29,320 Speaker 1: This makes me more confident that we might have discovered 329 00:17:29,320 --> 00:17:32,480 Speaker 1: a universal phenomena and it could be applied to many 330 00:17:32,560 --> 00:17:33,280 Speaker 1: other tissues. 331 00:17:33,480 --> 00:17:35,560 Speaker 2: That really is amazing. So what's the status of the 332 00:17:35,560 --> 00:17:36,520 Speaker 2: spinal cord repair? 333 00:17:36,560 --> 00:17:36,600 Speaker 1: Like? 334 00:17:36,640 --> 00:17:38,760 Speaker 2: Have they been able to test this in humans yet? 335 00:17:38,880 --> 00:17:42,240 Speaker 1: Fortunately not. The team's been petitioning the FDA for approval 336 00:17:42,280 --> 00:17:44,840 Speaker 1: to start clinical trials, but so far it's yet to 337 00:17:44,880 --> 00:17:45,440 Speaker 1: be granted. 338 00:17:45,600 --> 00:17:47,800 Speaker 2: Well, I hope it does come through sooner rather than later, 339 00:17:47,800 --> 00:17:50,240 Speaker 2: and it sounds like something that could seriously change people's 340 00:17:50,240 --> 00:17:52,160 Speaker 2: lives and of course the lives of mice as well. 341 00:17:52,240 --> 00:17:54,120 Speaker 1: Yeah, we'll have them all dancing again soon. 342 00:17:56,520 --> 00:17:59,359 Speaker 2: Well, our next breakthrough is a reminder that medical advances 343 00:17:59,400 --> 00:18:02,760 Speaker 2: can truly come from anywhere, even from inside the mouth 344 00:18:02,840 --> 00:18:05,720 Speaker 2: of a venomous lizard. Now we know this for a 345 00:18:05,760 --> 00:18:08,440 Speaker 2: fact thanks to the work of doctor John Aang. He's 346 00:18:08,440 --> 00:18:11,359 Speaker 2: an endocrinologist and VA researcher who found a way to 347 00:18:11,400 --> 00:18:15,399 Speaker 2: stimulate the insulin producing cells in the pancreas using a 348 00:18:15,400 --> 00:18:18,879 Speaker 2: hormone found in wait for it, the saliva of a 349 00:18:18,960 --> 00:18:19,720 Speaker 2: HeLa monster. 350 00:18:20,320 --> 00:18:23,000 Speaker 1: I feel like there's no way to make that not 351 00:18:23,160 --> 00:18:23,920 Speaker 1: sound crazy. 352 00:18:24,440 --> 00:18:26,919 Speaker 2: Yeah, Well, just to be clear, helo monsters are not, 353 00:18:27,160 --> 00:18:30,639 Speaker 2: in fact, spased monsters or aliens. They're big, desert dwelling 354 00:18:30,680 --> 00:18:34,000 Speaker 2: lizards native to the southwestern United States. They can grow 355 00:18:34,000 --> 00:18:36,359 Speaker 2: to be about twenty inches in length and are easy 356 00:18:36,359 --> 00:18:39,520 Speaker 2: to recognize thanks to their splotchy orange and black coloring. No, 357 00:18:39,600 --> 00:18:41,479 Speaker 2: it's rare to see one in person, though, since they 358 00:18:41,520 --> 00:18:44,920 Speaker 2: spend about ninety percent of their lives underground and only 359 00:18:44,920 --> 00:18:46,720 Speaker 2: come to the surface when it's time to eat. 360 00:18:47,040 --> 00:18:49,320 Speaker 1: I mean, if you dc one, you should probably clear away, 361 00:18:49,359 --> 00:18:50,640 Speaker 1: right because they're pretty venomous. 362 00:18:51,000 --> 00:18:52,680 Speaker 2: Well, you really don't want to mess with one of 363 00:18:52,720 --> 00:18:55,160 Speaker 2: these guys. They have a pretty powerful bite, and because 364 00:18:55,160 --> 00:18:57,719 Speaker 2: their main defense is to pump you full of venom, 365 00:18:58,040 --> 00:19:00,199 Speaker 2: they tend to hang on to whatever they chomp on 366 00:19:00,280 --> 00:19:04,640 Speaker 2: for as long as possible, and the venom glends are 367 00:19:04,680 --> 00:19:07,680 Speaker 2: inside their mouths obviously, right yeah, and they're they're lower jaws, 368 00:19:07,720 --> 00:19:10,440 Speaker 2: I think. So the longer a helo monster clamps down, 369 00:19:10,480 --> 00:19:13,359 Speaker 2: the more venom is injected through their teeth and into 370 00:19:13,400 --> 00:19:16,320 Speaker 2: the bite wound. It was unfortunate enough to have been bitten, 371 00:19:16,440 --> 00:19:19,960 Speaker 2: say the venom stings like molten lava, So these people 372 00:19:19,960 --> 00:19:22,600 Speaker 2: have not only been bitten, but they also have experienced 373 00:19:22,600 --> 00:19:27,840 Speaker 2: molten lava. Apparently are unlucky to keep rough, but for 374 00:19:27,920 --> 00:19:30,919 Speaker 2: people with type two diabetes, it actually can be a 375 00:19:30,960 --> 00:19:31,680 Speaker 2: life saver. 376 00:19:32,160 --> 00:19:35,600 Speaker 1: Which is wild. So how did doctor Ang even think 377 00:19:35,640 --> 00:19:38,600 Speaker 1: to try this? Like, like, why was messing around with 378 00:19:38,720 --> 00:19:42,320 Speaker 1: helo monster spit like the first thing you was thinking about? 379 00:19:42,640 --> 00:19:44,800 Speaker 2: I actually wondered that too. But keep in mind that 380 00:19:44,840 --> 00:19:48,600 Speaker 2: medications derived from animal venom aren't that unusual. Sure, the 381 00:19:48,680 --> 00:19:51,880 Speaker 2: venom of snakes, scorpion, spiders, even the world's only other 382 00:19:51,960 --> 00:19:55,720 Speaker 2: venomous lizard, the komodo dragon. They've all contributed to different 383 00:19:55,720 --> 00:19:58,720 Speaker 2: treatments over the years, and some of the existing research 384 00:19:58,840 --> 00:20:01,399 Speaker 2: is what convinced doctor Ng that helo monsters might be 385 00:20:01,480 --> 00:20:04,359 Speaker 2: helpful for treating diabetes. So let's go back to the 386 00:20:04,440 --> 00:20:07,240 Speaker 2: nineteen eighties, when doctor Ng was practicing as a physician 387 00:20:07,400 --> 00:20:09,760 Speaker 2: and a researcher at the VA Hospital in the Bronx. 388 00:20:10,240 --> 00:20:13,720 Speaker 2: He was working to discover new animal hormones with medical potential, 389 00:20:13,920 --> 00:20:16,960 Speaker 2: and since he was an endocrinologist, he was especially interested 390 00:20:17,000 --> 00:20:20,320 Speaker 2: in ones that might treat diabetes. This eventually led him 391 00:20:20,320 --> 00:20:23,280 Speaker 2: to an article from the National Institutes of Health about 392 00:20:23,280 --> 00:20:26,560 Speaker 2: the effects of certain snake and lizard venoms on the pancreas. 393 00:20:27,040 --> 00:20:29,960 Speaker 2: Studies showed that some venoms, including that of the Helo monster, 394 00:20:30,040 --> 00:20:34,120 Speaker 2: could trigger inflammation in the pancreas where insulin is produced. Now, 395 00:20:34,119 --> 00:20:36,639 Speaker 2: this convinced doctor Ing that the HeLa monster venom was 396 00:20:36,720 --> 00:20:39,520 Speaker 2: worth a closer look, and so in nineteen ninety two 397 00:20:39,960 --> 00:20:43,120 Speaker 2: he discovered a new hormone in the animals, salivam, which 398 00:20:43,119 --> 00:20:46,600 Speaker 2: he called extendin four Now. When he tested the compound 399 00:20:46,680 --> 00:20:49,000 Speaker 2: on mice, he was shocked to find that it reduced 400 00:20:49,040 --> 00:20:52,959 Speaker 2: their blood glucose levels by stimulating the insulin producing cells 401 00:20:53,000 --> 00:20:55,840 Speaker 2: in the pancreas. In fact, it worked very similarly to 402 00:20:55,880 --> 00:20:59,280 Speaker 2: the GLP one hormone found in the digestive tract of humans, 403 00:21:00,080 --> 00:21:04,040 Speaker 2: with one other important difference. Extending four degraded in the 404 00:21:04,080 --> 00:21:07,440 Speaker 2: body much slower, so for reference, a diabetic would have 405 00:21:07,520 --> 00:21:10,480 Speaker 2: to inject GLP one every hour to keep an effective 406 00:21:10,520 --> 00:21:13,800 Speaker 2: amount of insulin in the bloodstream, but extending four would 407 00:21:13,800 --> 00:21:16,960 Speaker 2: only need to be injected once a day, which obviously 408 00:21:16,960 --> 00:21:20,000 Speaker 2: sounds like a game changer. It absolutely was, but unfortunately 409 00:21:20,080 --> 00:21:22,240 Speaker 2: it took quite a while for doctor Ang's discovery to 410 00:21:22,280 --> 00:21:25,399 Speaker 2: get the attention it deserved. Although the VA had funded 411 00:21:25,400 --> 00:21:29,000 Speaker 2: his initial research, it showed very little interest in his findings, 412 00:21:29,440 --> 00:21:32,959 Speaker 2: and neither did big pharmam. Injecting diabetics with proteins from 413 00:21:33,040 --> 00:21:35,480 Speaker 2: lizard venom was just kind of deemed too weird for 414 00:21:35,560 --> 00:21:39,320 Speaker 2: mainstream medicine, so doctor Ang's research wound up languishing for 415 00:21:39,440 --> 00:21:42,720 Speaker 2: years until this small biotech startup with a focus on 416 00:21:42,840 --> 00:21:47,600 Speaker 2: diabetes finally took notice. So the resulting drug, exenotide, was 417 00:21:47,600 --> 00:21:50,080 Speaker 2: approved by the FDA in two thousand and five, and 418 00:21:50,119 --> 00:21:53,439 Speaker 2: it's now used by millions of diabetic patients worldwide. 419 00:21:53,760 --> 00:21:57,600 Speaker 1: I do love that these like venomous lizard creatures are 420 00:21:58,160 --> 00:22:00,760 Speaker 1: you know, these things that like everyone is afraid of, 421 00:22:01,040 --> 00:22:03,240 Speaker 1: are responsible for saving humans lives. 422 00:22:03,320 --> 00:22:06,600 Speaker 2: Yeah, and they don't even know it the lizards or 423 00:22:06,600 --> 00:22:07,000 Speaker 2: the people. 424 00:22:07,240 --> 00:22:10,840 Speaker 1: Yeah, also, the lizards might not be too happy about it. 425 00:22:10,920 --> 00:22:13,199 Speaker 1: I read that HeLa monster numbers are way down in 426 00:22:13,240 --> 00:22:17,520 Speaker 1: recent years because we keep destroying their habitats, and if 427 00:22:17,520 --> 00:22:20,760 Speaker 1: we aren't careful, we might lose those little guys completely. 428 00:22:20,440 --> 00:22:22,720 Speaker 2: Which would be a huge loss, even from a self 429 00:22:22,760 --> 00:22:25,080 Speaker 2: serving perspective. I mean, if they prove this to be 430 00:22:25,200 --> 00:22:28,120 Speaker 2: useful and humans wants, who's to say other medical secrets 431 00:22:28,440 --> 00:22:29,440 Speaker 2: might be hiding in there. 432 00:22:29,960 --> 00:22:32,280 Speaker 1: I also think it's kind of a branding problem, Like 433 00:22:32,400 --> 00:22:35,520 Speaker 1: if we renamed them helaqds instead of Heala monsters, I 434 00:22:35,520 --> 00:22:36,840 Speaker 1: feel like they'd have more of a chance. 435 00:22:37,040 --> 00:22:39,520 Speaker 2: I think that's a great idea. Maybe we should push 436 00:22:39,520 --> 00:22:39,720 Speaker 2: for that. 437 00:22:40,400 --> 00:22:43,040 Speaker 1: Anyway, that's it for today's episode. Be sure to tune 438 00:22:43,040 --> 00:22:46,080 Speaker 1: in tomorrow for our big, big finale, where we'll be 439 00:22:46,119 --> 00:22:48,960 Speaker 1: counting down to the number one greatest science idea of 440 00:22:49,040 --> 00:22:52,080 Speaker 1: the past twenty five years.
