Latest / From First Principles / 2026 Nobel Prize Predictions: Medicine, Physics & Chemistry (EP 60)
Transcript
- 0:00Well, I received a phone call at nine minutes past two in my morning, and I thought, well, this is obviously a junk call.
- 0:11Every October, somewhere in the world, a phone rings before sunrise.
- 0:18Last year, the call went to scientists who showed how the immune system keeps itself in check, who built molecular frameworks full of open space, and who made an electric circuit behave like a single quantum particle.
- 0:36Next week, for the second year running, we'll be up at 2 a.m. to find out who gets the call.
- 0:44Today, we're making our picks.
- 0:47This is From First Principles, and this is our 2026 Nobel Prize Preview.
- 0:57Hello, Internet.
- 0:58This is your captain speaking, Lester Nare, joined as always by my co-host and our resident PhD, Krishna Chowdhury.
- 1:07We are back from our trip to Washington, D.C. for the Golden Goose Awards, and we are preparing for one of the biggest weeks in science, Nobel Prize Week.
- 1:19For those of you who have been here since last year, we did a huge weekly special, Daily Drops, and beforehand,
- 1:26We did a predictions episode in which our resident PhD had one out of three.
- 1:32Quite nice.
- 1:33That's quite nice.
- 1:33It's quite nice.
- 1:35And we are going to do the same this week.
- 1:37We're going to keep it nice and light and tight because we have an action-packed week coming up for you.
- 1:43As always, we are going to talk about the science from the ground up today because this is From First Principle.
- 2:03Next week, the Nobel Prizes start on Monday with medicine and physiology, and we're going to jump right in to our first prediction for medicine.
- 2:14So the first prediction for medicine is something that a lot of people have been calling GLP-1.
- 2:21This is the glucagon-like peptide 1.
- 2:24It's a hormone that's released by the intestinal cells after a meal.
- 2:28It helps stimulate insulin secretion in the pancreas when glucose is elevated, and it coordinates communication between the gut and the pancreas.
- 2:36It also, importantly, affects appetite and the movement of food throughout the stomach,
- 2:43It's been all the craze lately in Los Angeles and America and the world because the GLP-1 drugs like Ozempic and Wegovi have been used as a treatment for diabetes, but also as a treatment for weight loss.
- 3:00Yeah.
- 3:01There was an early scientific challenge in identifying what the active peptide is, because you can't just look at what the big protein is.
- 3:10The big protein is called pro-glucagon, but it's really cut up into different products and different tissues.
- 3:16So you can imagine...
- 3:17You can't just look at the gene because the gene is going to give you the giant protein.
- 3:21I want the peptide, which is the smaller part of the protein.
- 3:24And that was a big challenge.
- 3:26And the significant challenge was solved by a bunch of pioneers.
- 3:30We're going to go through some of them whom I think are going to be involved if GLP-1 gets the Nobel Prize.
- 3:36So the first one is Svetlana Majsov.
- 3:40She identified and synthesized the active form of GLP-1, and she helped establish its intestinal origin and the fact that it stimulates insulin.
- 3:52So she's a research professor at the Rockefeller University in New York.
- 3:55She did her PhD there also at Rockefeller.
- 3:59The next one that I think would probably be involved is Jens-Jule Holtz.
- 4:05His group independently helped establish those same properties.
- 4:09So frequently, the Nobel Prize will be given to both if it happened concurrently at the same time.
- 4:14And that's why I think he's probably in the contention.
- 4:16University of Copenhagen is his home.
- 4:19And finally, Daniel Drucker, he contributed experiments showing that the glucose-dependent insulin secretion and the broader physiology...
- 4:31is in fact these glocogon-like peptides.
- 4:34So he's a professor at the University of Toronto, and also he's affiliated with Massachusetts General Hospital and Harvard.
- 4:42Now, that's already three, right?
- 4:44Yeah.
- 4:45And the Nobel Prize very famously is only given to three.
- 4:48Max is out.
- 4:49Max is out at three.
- 4:51The trouble with GLP-1, which is why I think this is kind of a far chance, because there is a fourth involved that is very heavily involved.
- 5:01Lottie Bieri-Gnutzen.
- 5:05She was at Novo Nordisk, and she's part of the team that attached a fatty acid chain to the GLP-1 analogs.
- 5:12And this is what turned it into a drug.
- 5:15It went from just a peptide that's found normally, but if you just inject GLP-1, you're going to throw up.
- 5:20You need a kind of mediary that helps it...
- 5:23do the types of regulation that we know from the GLP-1 associated drugs.
- 5:29So she's a strong possible recipient.
- 5:32She's the chief scientific advisor for research and development at Novo Nordisk right now.
- 5:37And, you know, the...
- 5:42there was a breakthrough prize, I believe in 2024 or 2025, that was given to all four of them.
- 5:49Interesting.
- 5:50Okay?
- 5:50Yeah.
- 5:51So there were the three scientists, and then there was this person who really pushed it to become the kind of treatment option that it's available today.
- 5:59The practical application.
- 6:01Yeah, yeah.
- 6:01So if GLP-1...
- 6:04is something that the Nobel Prize Committee deems worthy.
- 6:07It's going to be interesting how they distribute it.
- 6:09Like, who are the three out of the four that they choose?
- 6:12Uh-oh.
- 6:13Uh-oh.
- 6:14And for listeners of the pod, you will recall that we discussed GLP-1 in the context of also having been a former winner
- 6:27Of the Golden Goose Award.
- 6:28That's right.
- 6:30Based on some research as it relates to Gila Monsters.
- 6:34Not Gila Monsters.
- 6:35Gila.
- 6:36Thank you.
- 6:36Gila Monsters.
- 6:36That's right.
- 6:37For everyone correcting our American pronunciation.
- 6:42And it's obviously something that people get inundated with with ads regularly.
- 6:45on Instagram, et cetera.
- 6:47Yeah.
- 6:47And I think the through line is, yes, great.
- 6:51You know, we have something that is attacking an issue that impacts a lot of people and has been beneficial to many.
- 6:58But it does, again, start with some fundamental understanding that then leads to the practical application.
- 7:05This, I think, is one of the most popular things
- 7:09predictions out there predictions on all of the markets and all this other stuff yeah yeah the only reason why i think it's a far-fetched is because there's four involved you know i think this is one of those where um maybe they'll have a deal with the chemistry people to like give some of it to the chem and some of it to bio or something like that
- 7:29Or they do the classic thing where they wait for one of them to die.
- 7:33And then immediately give it to the three that are left standing.
- 7:36Which, if you watch our last year's Nobel coverage, we talk about that context, which is a classic move for the Nobel Committee.
- 7:45Yep.
- 7:46All right, so the second prediction that I have is something that I've recycled from last year's predictions.
- 7:52This is optogenetics.
- 7:56Optogenetics is...
- 7:58an incredible technology that is now used not only in neuroscience, but all over cellular biotechnology assays.
- 8:07The idea is that there's a specific protein that has been discovered called channel rhodopsin.
- 8:13It's a channel protein, meaning that it lets ions through.
- 8:20It sits on the membrane between the outside and the inside of the cell.
- 8:24And it's rhodopsin, because that reminds you of the rods and cones, the rods in your eyes.
- 8:29It is light sensitive.
- 8:31This is a protein that was originally identified in green algae, and it forms an ion channel on the membrane.
- 8:38The idea is...
- 8:40you can shine light on it of a particular frequency, the protein is going to absorb that photon and then use the energy of that photon to change its shape and open up or close, depending on what this specific protein is trying to do.
- 8:55Crucially, this gives us the ability to not only read,
- 8:59but also write into the neurons, right?
- 9:02We can now actively affect what the neurons are doing.
- 9:05This is not the first time that we've been able to write stuff.
- 9:07Obviously, Neuralink, for example, is read and write as well, and that uses electrodes that are going right next to the neurons, and if you send out a voltage pulse, then that's going to affect the molecular environment, right?
- 9:20Here, on the other hand, you can very specifically tag...
- 9:24specific types of neurons.
- 9:26So you can have a virus, for example, that is modified, obviously.
- 9:32And this virus has the DNA for channel rhodopsin.
- 9:35And it's also got a marker that lets it only infect certain types of neurons and not others.
- 9:40So it's going to infect those neurons, put in this DNA for channel rhodopsin.
- 9:45The cell is going to make channel rhodopsin and express it on its outside.
- 9:49And then I can shine light on it and turn on and off
- 9:53Only those specific types of cells, whether it be pyramidal neurons or like inhibitory neurons, whatever I want, I can sort of engineer and make happen within a living, breathing animal.
- 10:06I remember when we talked about this the first time and it was such a mind-blowing concept.
- 10:10Again, the ways in which we are so clever in how we try to have impacts on our biology.
- 10:17and using the existing mechanics of how biology works generally and just manipulating it for an outcome that we want that's controllable.
- 10:29Again, not to continue to pump up last year's coverage, but we had a deeper dive on channel adoption at the time.
- 10:39And so if you're curious to learn more about it, check our preview episode from last year.
- 10:44Yeah, I mean, it's absolutely incredible because it's been used, it's used in every single university.
- 10:49There is a research lab, actually usually several, that use optogenetics.
- 10:54And the key idea is when we can manipulate circuits like this, we can then turn them on and off.
- 11:01We can couple them to behavior experiments.
- 11:04and then we can see what specific circuits are doing, right?
- 11:07In terms of all the way from the genetics all the way down to behavior.
- 11:11Right.
- 11:11Because we have this control knob.
- 11:12Right.
- 11:12So it's been incredible for the bio-research community at large.
- 11:18So there are a few people that are involved here.
- 11:20First one, I would think, is Peter Hageman.
- 11:23He is the professor of experimental biophysics at Humboldt University at Berlin.
- 11:28He studied the chemistry of this protein itself, and...
- 11:33His research was basically on how algae responded to light.
- 11:36He's the guy who discovered the protein in the first place.
- 11:39After that, Carl Diceroth and Edward Boyden in 2005 and all of their collaborators at Stanford, they demonstrated precise optical control of mammalian neurons using channelrhodopsin.
- 11:52So, you know, having it in algae is one thing, but modifying it a certain way, making it compatible with mammalian neurons, that was something else.
- 11:59And that is what has led to the boom for over the past 20 years of using this as an experiment.
- 12:06It's been absolutely massive.
- 12:10I think this has contention, which is why I'm recycling it from last year.
- 12:16Right, we're taking a second bite at the apple here.
- 12:18Yeah, I really think this could happen.
- 12:20There's one other guy, Garam Misenbach.
- 12:25He's also predicted...
- 12:27If they give it to Misenbach, they're probably not going to give it to Boyden because Boyden was a PhD student at the time.
- 12:33But Ed Boyden at MIT now has really taken this to the next level.
- 12:37So, again, this is going to be one of those where it's interesting.
- 12:39If they give it to optogenetics, which three are they going to choose?
- 12:44This is so – I think, like many things, it's a little bit subjective.
- 12:51There is obviously backing to it.
- 12:53Yeah.
- 12:54But when you have the limitation of saying only three, someone's got to sit on the bench.
- 13:01Yeah.
- 13:01Not everyone can be a starting player.
- 13:02Exactly.
- 13:03Yeah.
- 13:04And that's tough.
- 13:06And all four of these guys are quite young.
- 13:09Yeah.
- 13:10And so you can't really wait.
- 13:12Right.
- 13:12You can't wait for them to die.
- 13:16So that one's going to be interesting if that goes.
- 13:19And the last prediction I have for medicine, medicine is the only one where I have three, because I think it could be either one of these three.
- 13:26But again, honestly, it's a crapshoot, so probably not, right?
- 13:29But the last one that I have is optical coherence tomography, or OCT.
- 13:35This produces a cross-sectional image of tissue using light.
- 13:40It's a major, major medical application, right?
- 13:43Usually we use this on the retina where there's thin layers that can become distorted.
- 13:48They can lose cells.
- 13:49They can accumulate fluid.
- 13:51OCT reveals that internal structure without actually cutting into the eye.
- 13:55So this non-invasive imaging is really, really nice.
- 13:59The challenge always is like determining depth.
- 14:02Like here, over here, we're seeing a cross-section, right?
- 14:05And we're using this optical...
- 14:08coherence tomography to to look at what the depth is in a tissue you would think that the depth you can just find by shining light and then seeing when the light bounces back but this is at the micron level okay so getting that timing is going to be insane with google maps at the micron level for tissue yeah yeah and you can't really look at delays in light so what they do here instead is they use interference they have a reference light and then they have light that goes in and out and then depending on you know
- 14:36The timing, there's going to be phase accumulation, and then that is going to interfere with the reference light, and that's going to give you a kind of timing signal at the end of the day.
- 14:46Right?
- 14:46It's quite clever.
- 14:47That's clever.
- 14:48This one's actually kind of clean.
- 14:51Okay.
- 14:51There's three that are involved.
- 14:52Okay.
- 14:53They published their paper in 1991.
- 14:55So it's also, you know, 30 years now, 35 years since... Sweet spot.
- 15:00So it's a sweet spot of like, okay, and it's been used for so much because...
- 15:05Like OCT now helps clinicians track glaucoma and retinal disease.
- 15:10So it's been used in treatment, which kind of goes back to Nobel's original will, where he said, you know, for the benefit of mankind.
- 15:17Well, this is pretty clearly for the benefit of mankind.
- 15:20So the three that I think are going to get it are James Fujimoto, David Huang, and Eric Swanson.
- 15:26They had their foundational paper in 1991.
- 15:29Their early retinal images led to imaging living eyes and the practical clinical instruments.
- 15:36Fujimoto is the professor of electrical engineering and computer science at MIT.
- 15:41Huang is at the Oregon Health and Science University in Portland.
- 15:46And Swanson is also at MIT's research lab of electronics.
- 15:50As you can tell this year, we're toning down the MIT hate a little bit.
- 15:55Look, if they win, though, it's going to happen.
- 15:57We got very lucky last year that we had two alma maters win between both Princeton and UCLA.
- 16:03And all three were University of California.
- 16:06Yeah.
- 16:06Yeah.
- 16:06Right?
- 16:07Like the physics prize.
- 16:09Physics prize was all University of California.
- 16:11The medicine prize had one UCLA graduate.
- 16:15And Omar Yagi, obviously, was a professor at Berkeley at the time.
- 16:19At the time.
- 16:20California forever goodbye.
- 16:23It's not looking good based on these predictions this year.
- 16:26It's not looking good.
- 16:26No, but physics is coming up.
- 16:28Okay.
- 16:28We're still getting early.
- 16:29We're still early.
- 16:30Yeah.
- 16:31And so those are the three predictions for medicine.
- 16:34We're going to take a quick break for some housekeeping.
- 16:37As we said, it's been, we've had several episodes in a short period of time.
- 16:42We love you so much.
- 16:43We want to get you the best content as much as possible.
- 16:45I do want to touch on briefly a few thank yous from our last week to our trip to DC for the golden goose award.
- 16:57Real big thank you to all the team at triple AS and GSG who were our
- 17:02extremely helpful in setting up all of our interviews and taking care of us throughout the day.
- 17:08All of the awardees, you guys were fantastic.
- 17:11We look forward to continuing the conversation.
- 17:14That episode again will come out after Nobel week where we have our interviews for those who watched our last episode where we walked through the background of all of the folks on
- 17:25that received a golden goose award this year.
- 17:28And, um, it's, you know, it's a community that makes this stuff happen.
- 17:34And, uh, I think it's important that we continue to find ways to take the folks doing the work and giving them a platform, um,
- 17:40For those who may be new to From First Principles, welcome to the best science show on the planet.
- 17:45You can listen to us on YouTube as well as all of your favorite podcast platforms.
- 17:50Video is available on Spotify and YouTube.
- 17:53Apple podcast coming soon.
- 17:55We have not forgot about you all.
- 17:57If you enjoy the show, one of the best ways you can help us out is engaging, like, comment, share, subscribe, five-star review on the podcast networks.
- 18:05It helps us grow so people know that this is the best and helps us continue to be able to provide feedback.
- 18:12value for all of you if you're interested in any of the research papers or background information that we talk about our website ffppod.com has all those research papers several other cool science related interactive things you can do uh it's quite nice and with that the shilling is over and we're going to get to the most important nobel prize i didn't say it
- 18:40the physics Nobel Prize.
- 18:41And so we have, I believe, two predictions.
- 18:44Yes, we've got two predictions.
- 18:46The first one I think is really a no-brainer, and I cannot believe that the Nobel Committee still hasn't given him a Nobel Prize.
- 18:54This is also a recycle from last year, because I am fully convinced that this guy deserves it.
- 19:02This is Yakir Aronoff and the Aronoff-Bohm effect, which he and David Bohm described in 1959.
- 19:09David Bohm is the very famous physicist behind the pilot wave theory, or the pilot wave interpretation of quantum mechanics.
- 19:16This was the first non-Copenhagen interpretation of quantum mechanics.
- 19:20Niels Bohr ran him out of Copenhagen when Bohm went over to try to pitch.
- 19:27And then he was run out, very sadly, of the country, because this was the McCarthy era, and he was ideologically a communist.
- 19:36So he had to go to Brazil for the rest of his career, which, you know, given his stature, he could have done a lot more in some of the bigger universities.
- 19:47But he went to Brazil.
- 19:50He had a nice time there.
- 19:52The Arnav-Bom effect...
- 19:54People have said that this is the biggest development in quantum mechanics since...
- 20:02Dirac's prediction of antimatter.
- 20:07Okay?
- 20:07Pretty good.
- 20:08That's pretty good.
- 20:09The Arnoff-Bomb effect is so fundamental, it doesn't make sense why it hasn't gotten a Nobel Prize.
- 20:15Seriously.
- 20:15So here's the idea.
- 20:16The Arnoff-Bomb effect, and hopefully, I really hope they do give him the Nobel Prize, because then I get to do a deep dive on it for 45 minutes.
- 20:23But I'm going to give you a real quick...
- 20:27justification of the whole thing.
- 20:28So remember the double-slit experiment?
- 20:31The idea was that you have two paths that the photon can go through, or the electron can go through, and then it interferes in the back, and you get an interference pattern.
- 20:41And this is key to quantum mechanics.
- 20:45So now imagine, actually, if we can bring that photo 11.
- 20:50So now imagine we've got
- 20:54a beam splitter of electrons this time the electron follows one path to the left, one path to the right and it meets back up recombined at a detector in the back, right?
- 21:06and in the middle, in between these two paths is a solenoid
- 21:11that has a current going through it.
- 21:13And because it has a current going through it, inside the solenoid, there's going to be a magnetic field.
- 21:18But if you remember from your undergraduate physics, outside the solenoid, the magnetic field is zero.
- 21:24Because you can run Ampere's law outside the solenoid, there's no current that's involved because there's net current going in, net current coming out in those directions.
- 21:34And so there's no actual current
- 21:36which means there's no magnetic field outside the solenoid.
- 21:39The magnetic field is localized inside of the solenoid, okay?
- 21:45Now, for all intents and purposes in physics, the field is the real thing.
- 21:49But you can construct fields out of potentials.
- 21:52For example, the gravitational field is the real thing, but in order to sort of do mathematics with the gravitational field...
- 22:00We can invent something like a gravitational potential and say that, you know, the potential here is something.
- 22:06The potential here is a little bit more.
- 22:08And so the amount of energy it takes for me to go against the field is just the difference in the potential.
- 22:13And it's always the difference in the potential.
- 22:15I think the example you talked to me about one time is like imagine a hill.
- 22:19And you have someone that you're at the top of the hill or the bottom of the hill.
- 22:22Exactly.
- 22:22And your gravitational potential at the top of the hill is greater.
- 22:25And then it could do that.
- 22:27And then you can figure out how fast a ball would roll down the hill based on the difference.
- 22:30Yeah.
- 22:31Now, the key thing is, if I had the hill down at sea level, but then I took the same, like, cardboard landscape, let's say, of the balls rolling and I've got a cardboard landscape, and I took it up to Mount Whitney, as long as the gravitational field is exactly the same, it doesn't matter if I'm at Mount Whitney or at sea level, the dynamics on my cardboard mesh thing is going to be exactly the same.
- 22:52Yeah.
- 22:53Right?
- 22:53Because the only thing that matters is the difference in the potential.
- 22:57Okay, that's fine.
- 22:58Um...
- 23:00For magnetic fields, we can also construct a potential that describes a magnetic field.
- 23:04But instead of a scalar potential, which in this case is just height, so there's no vector, right?
- 23:09It's just a number.
- 23:10For a magnetic field, it requires a scalar potential.
- 23:13I mean, sorry, for the magnetic field, it requires a vector potential, not a scalar potential.
- 23:18Now, that introduces some interesting things.
- 23:21Because if you've got a vector potential, then all of a sudden direction matters in terms of like which way you're traversing this potential.
- 23:27But the potential is just a trick, right?
- 23:30It's supposed to be a mathematical trick.
- 23:32The field is the real thing.
- 23:34And in the Arnav-Bohm effect, my electron is moving one way and the other way.
- 23:38The field is in the middle.
- 23:39The solenoid is in the middle.
- 23:41And the field is localized inside the solenoid.
- 23:43So it shouldn't affect the two paths.
- 23:46that ends up not being true.
- 23:47If I turn on the magnetic field on and off, that changes my interference pattern.
- 23:52So this is very strange.
- 23:54Yeah, right, right.
- 23:54Because the institutional understanding was there should not be an effect on your beam outside of the solenoid.
- 24:03Outside of the solenoid, because the field is the real thing.
- 24:06Here, we're saying perhaps the potential could be a real thing.
- 24:09It's not just a bookkeeping thing, right?
- 24:11There are multiple interpretations of how this thing works.
- 24:14But the fact that it works and that I can experimentally do it introduces a lot of nuance into how we understand quantum mechanics.
- 24:23And that's why it's one of the biggest developments since Dirac's equation and his prediction of antimatter.
- 24:30So this was in 1959.
- 24:31It's quite late in terms of fundamental quantum theory, and here yet you have something that is so fundamental and so in your face, and something that we don't really quite...
- 24:42understand from a philosophical and metaphysical level.
- 24:45Okay?
- 24:46We can do the calculations, right?
- 24:47It turns out that, you know, what you have to do is the quantum interference depends on the complete path geometry.
- 24:53Not just on these two paths, but like you do a sum over paths on every single one, and perhaps maybe there's some to go through.
- 24:59it's still like you know is that is that really what's happening and wavy yeah um like but the the local force along the path is not the only thing that matters that's the key right yeah there's there's like it's it's it's a global thing it's a global phenomenon i and i one of the things that always trip that trips me up but um is so interesting when we talk about these quantum mechanical stories is this idea that
- 25:28You have, it's not just everything matters, even the things that are not what you end up seeing experimentally.
- 25:35Exactly.
- 25:35And that is a brain teaser.
- 25:39Yeah.
- 25:40Yeah.
- 25:40In terms of how your frame, your mental framework about what it is, all this stuff around us and reality and the physicality of it.
- 25:49The physicality is not, that we can engage in at the human scale is not the only thing.
- 25:55It's not the only thing.
- 25:55Yeah.
- 25:56It's, I mean, it's a trip.
- 25:57Every time you dive too deep into it.
- 25:59Yeah.
- 26:00Yeah.
- 26:01So David Baum died in 1992.
- 26:03And so Yakir Aronoff would be the only recipient.
- 26:07He's actually a professor of theoretical physics at Chapman University in Southern California.
- 26:11Oh, look at that.
- 26:12Right?
- 26:12So this would be a long time coming, I think.
- 26:17He published that paper in the late 1950s when he was a doctoral student.
- 26:22So this would be one of the record holders for the amount of time it took.
- 26:28To get it.
- 26:28From 1959 until now.
- 26:31That would be a big one.
- 26:31Yeah.
- 26:33Michael Berry, we were just on the Instagram live before taping this, and someone said Berry.
- 26:39This is who they're referring to.
- 26:41Michael Berry is a natural possible co-recipient.
- 26:44In 1984, he showed that a quantum state can acquire an additional phase when the parameters slowly trace some type of closed loop.
- 26:52It's a topological argument.
- 26:54It's related to the Arnav-Bomb effect, but not exactly the same.
- 26:59Again, topological physics is something that is incredibly important.
- 27:03Deep, complex, and yet simple.
- 27:06So, you know, if the Nobel Prize Committee decides to award topological physics another Nobel Prize, I'll have a field day explaining it.
- 27:15That'll be really fun.
- 27:18Does this relate to when we had these conversations about gradient descent?
- 27:21Kind of.
- 27:23And relate in the...
- 27:24related concepts i can't remember what episode it was um we had one where we went really deep on it um but it's escaping me right now however if there's a win we will cover it yeah we will cover it for sure uh physics 2 i'm gonna be honest this is also a recycle from last year because i really do think afm is something that deserves it okay this is the atomic force microscope
- 27:51This one is so crazy.
- 27:52Yeah, this one is huge.
- 27:55Here's the idea.
- 27:56With the AFM, the Atomic Force Microscope, you can scan a sharp tip that is like...
- 28:03At the level of angstrom's thick at its tip.
- 28:06Like this is like something that is like at the atomic resolution.
- 28:10And what you do is you run a surface across it and it measures the interaction between the tip and the sample.
- 28:17I want to just double click on this.
- 28:20We're talking about very, very, very, very, very, very small.
- 28:25Yeah, like you see those hills and valleys there?
- 28:28Those are like on the orders of tens of atoms.
- 28:32Right?
- 28:33To now, I think people are doing like single atoms straight up.
- 28:35Which is so ridiculous.
- 28:37It's so ridiculous how we can sense such tiny, tiny perturbations.
- 28:43Right?
- 28:44It's completely led to the advent of precision nanotechnology.
- 28:51Yeah.
- 28:52A lot of really nice applications, like if we want to understand the stress and strain of materials at that scale, right?
- 29:00If we want to understand, for example, even biological membranes and biological tissue, what is the type of force that biology goes under at the molecular scale?
- 29:09We can use AFMs.
- 29:11It's an absolutely revolutionary technology, I think.
- 29:15Under suitable conditions, they can even resolve single atoms, right?
- 29:21So nuts.
- 29:23It's huge.
- 29:23I mean, there's manufacturing benefits.
- 29:26There's biological health medicine, clinical benefits.
- 29:28Research benefits, yeah.
- 29:29It just applies literally everywhere.
- 29:31Yeah, exactly.
- 29:33And so the original inventors were Jerd Binig...
- 29:37Calvin Kuwate and Christoph Gerber, they all received the 2016 Kavli Prize in nanoscience.
- 29:43Kuwate died in 2019, so if the Nobel honors them, it's going to be only Binnig and Gerber.
- 29:52Binnig is a retired physicist from IBM's Zurich Research Lab.
- 29:59And Gerber is the Department of Physics professor at the University of Basel.
- 30:04So this would be two Swiss recipients.
- 30:08Europe's on the board.
- 30:09Yep.
- 30:11Europe's on the board.
- 30:11It's not just California forever.
- 30:13Goodbye.
- 30:13I, I remember when we first, when we first talked about these and it was so early in the show and there were a lot of fundamental concepts that have stuck with me since in terms of being able to build further understanding in our future stories, just in terms of like, again, what's even possible.
- 30:31I mean, these things are not new.
- 30:33Yeah.
- 30:33And so we've come a long way.
- 30:36So when we talk about frontier research stories, you know,
- 30:38We're talking about much more evolved applications, not necessarily of these concepts specifically, but just if you can imagine we were doing these things such a long time ago.
- 30:49Yeah, this was 1986.
- 30:50Imagine what we're doing now.
- 30:51Right.
- 30:52So this was exactly 40 years ago.
- 30:54Yeah.
- 30:55And because of the AFM, we have such a...
- 30:59we have a much more finer understanding of nanotechnology, right?
- 31:04Without the AFM, a lot of the nanotechnology that we use in day-to-day lives wouldn't be possible because the AFM gives us a way to probe that scale and understand what's going on down there.
- 31:16It's like opposite world JWST.
- 31:19Yeah.
- 31:20In the other direction.
- 31:20In the other direction, exactly.
- 31:23We are going to move now to the final category.
- 31:26Again, we are going to be having coverage every day for the first three days for the only real Nobel Prizes.
- 31:35Medicine, physics, and our final category, chemistry.
- 31:40Actually, can I just caveat that?
- 31:42Peace and literature are real Nobel Prizes because Alfred Nobel put it in his will that he wanted peace and...
- 31:52Literature.
- 31:52So there's really five real Nobel Prizes because that's what was in Alfred Nobel's will.
- 31:58But what about economics?
- 32:00I didn't, I don't, you guys hear something?
- 32:04Chemistry.
- 32:05Let's talk about chemistry.
- 32:06This is an inside joke for those who are new.
- 32:09But yes, let us proceed to the chemistry Nobel Prize.
- 32:14The first one, this is a recycling from last year because I do think this deserves it.
- 32:18Biomolecular condensates.
- 32:20I'm going to say it again.
- 32:22These things are everywhere in biology, and they were discovered by chemists for a very good reason.
- 32:31The idea is in biology...
- 32:34You need to bring particular molecules together in the right places at the right time.
- 32:39You need compartmentalization.
- 32:41Biology usually does this using membranes.
- 32:44For example, this outer membrane that you're seeing here, that's the nuclear membrane, and that is separating the nucleus on the inside from the outside of the cells.
- 32:53That's nice in eukaryotes because you want to compartmentalize all of your DNA, all of your chromosomes.
- 32:59You don't want all of the cellular machinery running around trying to get to your DNA, right?
- 33:03And that's why we have the wall around our DNA.
- 33:08We keep that safe.
- 33:09And then we have RNA, mRNA, that goes outside and is kind of like hanging out with the plebs on the outside of the cell trying to make everything work.
- 33:17But look inside the nucleus, right?
- 33:19There is that blob, that orange arrow it's pointing to.
- 33:22Mm-hmm.
- 33:23That is the nucleosome.
- 33:25It's a compartment inside the nucleus itself.
- 33:29Some people like to call it the nucleus of the nucleus.
- 33:32And that's where a lot of the ribosome-making machinery happens.
- 33:36The ribosome is the protein-making factory of our cells, and the ribosomes are created in that nucleosome.
- 33:43But there's no membrane around that nucleosome, okay?
- 33:47The proteins just kind of aggregate there.
- 33:49The ones that are important for that particular process are just aggregating there.
- 33:53This is an example of a biomolecular condensate.
- 33:58It shows how compartments can form without actual membranes around them.
- 34:03The membrane-less compartment.
- 34:05Exactly.
- 34:06And the underlying physics is just phase separation.
- 34:09Okay?
- 34:09You can have proteins and RNA, and they can make weak contacts.
- 34:13And then those things can mix with other stuff.
- 34:16And you can kind of get, you know how oil separates from water very naturally?
- 34:21Yeah, yeah, yeah.
- 34:21Kind of the same way.
- 34:24These molecular condensates can separate from other dilute phases in a very natural way.
- 34:29And this is a purely physically driven entropic system.
- 34:32Like it's not, there's no active, like stuff is pushing, there's nothing active in an oil and water mixture that is pushing the oil together, right?
- 34:42Just the oil wants to be together and the water wants to be together because of the different chemistry.
- 34:47The same thing is happening here.
- 34:48There's different chemistry happening and that's what causes this phase separation.
- 34:52So who are the people involved?
- 34:542009, I would say Clifford Bregwein and Tony Hyman and their colleagues, they showed that these pea granules in roundworm embryos behave like liquids.
- 35:03And those granules could accumulate at one end of the embryo through dissolution in just one region and then condensation in another.
- 35:11So it's the same substance, but it would exhibit different chemistry because of its environment.
- 35:15which was very nice.
- 35:16And then in 2012, Michael Rosen and his colleagues, they showed how proteins with multiple binding sites could assemble into droplets.
- 35:24So you got a protein that's got multiple little magnetic sites where stuff can, stuff can like bind.
- 35:30And depending on the interactions, you can have,
- 35:33Those proteins coalesce into a compartment without anything on the outside.
- 35:40So where are these people?
- 35:41Bregwine is at Princeton University.
- 35:44Oh, we're on the board, baby!
- 35:46So he is a professor in the Bioengineering Institute.
- 35:50Hyman is at...
- 35:52EMBL, which is the European Molecular Biology Laboratory, that's based in Heidelberg.
- 35:57It's kind of like a Max Planck, but not.
- 36:00I don't know.
- 36:01If they win, I'm going to go into what exactly that thing is.
- 36:05But it seems something like that.
- 36:06And then Rosen is a professor at UT Southwestern Medical Center in Dallas.
- 36:12okay so texas is on the board yep uh okay so fingers crossed fingers crossed for biomolecular condensates i really think that that's a because that one's another clean like sort of three people yeah yeah you know yeah so um and related to the most important academic institution of course so yeah of all time of all time so it's not that would be great um chemistry two yes this one's
- 36:41It's called the Buchwald-Hartwig Coupling, and it's named after the two people that I think might get it if this is the thing that gets it.
- 36:50This is a widely used method for making carbon-nitrogen bonds.
- 36:54Nitrogen-containing groups are common in medicines.
- 36:57You attach the nitrogen to a certain position of a carbon ring, and that can change the molecular's charge, the molecule's charge, the solubility, the interaction with proteins.
- 37:10reaction is super important for creating drug therapies, right?
- 37:16In this case, what Hartwig and Buchwald did was they combined a mechanistic understanding with ligand design.
- 37:24Ligand is the molecule that bounds to some kind of catalyst.
- 37:28In this particular case, the catalyst that they always use is palladium, which I think is the same...
- 37:36It's the same metal that was used by Iron Man in the cave to create the...
- 37:40He did this in a cave.
- 37:41Yeah, he did this in a cave.
- 37:42The pot's scratch.
- 37:43Yeah, yeah, that was palladium, I'm pretty sure.
- 37:46In any case, that metal is kind of an intermediary that bridges this gap between the carbon...
- 37:52removing, like, let's say the bromine in this case, and then attaching a nitrogen there.
- 37:57And you can use this to control exactly where to attach the nitrogen in a convoluted organic molecule.
- 38:04This is huge because for drug discovery, this lets chemists make families of related molecules, and then you can test how different nitrogen groups affect biological activity.
- 38:14So they actually shared the 2019 Wolf Prize.
- 38:19They were recognized for their catalytic work.
- 38:22So Buchwald is a professor of chemistry at MIT, and Hartwig is a professor of chemistry at University of California, Berkeley.
- 38:30So California on the board again.
- 38:32I don't know what to tell you guys.
- 38:35I think we're going to have some fun.
- 38:38Yeah, and those are my predictions.
- 38:40Let's see.
- 38:41Let's see.
- 38:42We wanted to keep it quick and tight today.
- 38:44We have a lot to prepare for next week for a fast turnaround after having just come back and still working through our interviews.
- 38:52And so for those who like long episodes, tune in next week.
- 38:57We're definitely going to get into the weeds.
- 38:59But please let us know for those who have finished, which should be most of you because this week's episode is very short.
- 39:06Let us know in the comments before Monday.
- 39:10What do you think is going to win a Nobel Prize in these categories?
- 39:14And then we'll see what happens.
- 39:16And if you end up being right, we'll make sure we comment back.
- 39:20So we're super excited.
- 39:22It's going to be a lot of fun.
- 39:24And maybe we'll do a little bit of a little live preview for those on Instagram.
- 39:29We did a couple of lives.
- 39:30We did a couple of lives.
- 39:31For fun.
- 39:32At the unction, as the kids say.
- 39:34Because we don't understand how to use these things anymore.
- 39:38But it's great to be able to interact with many of you.
- 39:41But with that, we are going to end nice and quick this week.
- 39:46Well under an hour.
- 39:48This is shocking levels.
- 39:49It's the first time in a while.
- 39:50Yeah.
- 39:51shocking levels probably in a year the last time was when we did the nobel prize episodes oh we know you guys like the long form we want to get you our predictions before we get into the good stuff my name is lester nare joined as always by my co-host and our resident phd krishna chowdhury we will see you all next week for the nobel prizes
