44:54to one specific site >> of the body versus another things like that it could be very useful >> we've been hearing about the potential of nanotechnology since I think I was like in middle school about how it's the next frontier and all these things um this is a real practical um you know it reminds me of the programmable protein story we covered from Yale in last season. >> Uh we're doing >> greater and greater things at smaller and smaller scales. >> Uh and again the >> the applications, you know, >> eat your heart out. It's it's it's endless. Uh that's a really really good story. Our last story for the rundown today is about Leonardo DiCaprio. Uh
45:37genetic clues >> da Vinci. >> Oh, excuse me. [laughter] It's Golden Globes. Excuse me. I saw that clip of him talking about K-pop demon hunters. >> Da Vinci, the one from the 1500s. >> Yeah. >> Genetic clues may be hiding in his artwork. Uh there were many institutions involved in this one. Uh the Venttor Institute, Vanderbilt uh uh Vanderbilt University Medical Center and the University of Maryland. Uh this was out in bioarchchive. And the idea here is that the artist, inventor, and uh uh all-around genius uh Da Vinci was sort of the definition of the Renaissance man. Obviously, we have the Da Vinci Code, all these books, all
46:17this stuff. And scientists have been aiming to unlock the secrets of his genius on a genetic level. Uh but there's just one small problem. Uh more than 500 years after his death, uh his DNA has proved virtually impossible to locate. >> Yeah. >> No kids. His grave was destroyed during the French Revolution. >> Yeah, that's not the only thing that was destroyed in the French Revolution. Let me tell you that. [laughter] But uh you know, that's my jab at the French. There's going to be another one later in the episode. [laughter] In any case, I don't know why, but like there's this thing called the Leonardo Project, and there they're obsessed with all things Leonardo, and they really want his DNA. Okay, they want to sequence his DNA. Um, what the project's
46:58team did was they swabbed letters that were written by a distant Leonardo relative and they also swabbed something called the holy child, which is a drawing that was possibly created by Leonardo. >> And they found um a Y chromosome, >> okay, >> which is the chromosome that >> is in all males and there's not a lot of mutations. So, if there's a distant Leonardo relative and then this swab from the letter is actually matching, then it's very highly likely that it is Leonardo. And this kind of reminded me of there was this documentary called The Lost Leonardo. >> It was about this painting, Salvador Mundi. >> Mhm. >> That was apparently the lost Leonardo da
47:40Vinci painting. He he only made a handful of paintings, something like 10 or 15, less than 15. And each one of his paintings are masterpieces. The first painting that I ever saw was Madonna with child in the um gallery at Lond in London. And it it is it is like quite amazing just the way that he shades painting paint together and the the the faces that he makes are just like incredible. Um this particular painting, the Salvatore Mundi, it's sold for $450 million. It's the most expensive painting to have ever been sold by Christies and it is currently owned by Muhammad bin bin Solomon of Saudi Arabia. He's trying to open a new um art
48:23gallery in Saudi Arabia and this is going to be the big masterpiece there. It's debated whether Salvatore Mundi is from Leonardo. Okay. >> Okay. But if we could figure out like a scientific way to say this is Leonardo or not, then you know you could actually see whether he made the bet was correct or not. >> We are giving new meaning to the common phrase the Da Vinci Code. >> Yeah. >> Um >> Oh yeah, nice one. [laughter] >> I do this professionally. >> Uh great five stories on the rundown today. prehistoric woolly rhino.
49:05The roll out of an 11 million pound rocket in preparation for Artemis 2 launch. We figured out why teens get to communicate better in their brain because of all these new synaptic connections. Nanobots are here. >> Yeah. >> And we may finally have the DNA of Leonardo da Vinci so that we can genetically replicate him and have a bunch of geniuses running around. We are now going to move into our next story which is about something very fascinating that I've never heard of which is time vaults. >> Yeah.
