    Glad to see Rose hosting an episode again! It's pretty funny that when lasers were first developed they were criticized as "a solution looking for a problem". Now we've figured out ways to use them to tweeze apart DNA, cool atoms to tens of microkelvins, send large quantities of data over optical fibers, and all sorts of other amazing things. In a way, that saying was true, but lasers just happen to be a solution for so many things we keep finding new problems for them to solve 😁

      ​@@MarkWTK ooh yeah that's another great example! It's amazing people have managed to not only figure out but then build a machine that can hit a droplet of molten tin with a laser once to turn it into plasma then a second time to generate a powerful EUV source.

    First they take the dinglebop, then smooth it out with a bunch of shleem. The shleem is then repurposed for later batches.They take the dinglebop and push it through the grumbo. Where the fleeb is then rubbed against it. Its important that the fleeb is rubbed, because the fleeb has all the fleeb juice. Then a shlammie shows up and he rubs it and spits on it. They cut the fleeb. There are several hizzards in the way. The blamfs run against the trumbles and the ploobis and grumbo are shaved away. That leaves you with a regular old plumbus

    DNA is such an incredible thing. I'm excited for the future where we can use DNA for data storage. Surprisingly stable if you keep it in optimal conditions and exceptional data density. Reading it quickly, mitigating data loss, and keeping it stable are some of the main issues with it, but even if the storage devices using it are huge and slow, they would be perfect for storage of data where you don't need instant access.

    I have a DNA-related question:
    Can CRISPR be used to insert missing proteins into DNA?
    I recently found out that I'm missing two proteins in my DNA and I'm wondering if that's at all possible.
    My oncologist said that missing one protein is rare enough, but to be missing two proteins is, apparently, completely unheard of. Based on that, I'm guessing that there's not a lot of research being done on this.

    • @ericwright8592

      The issue is you don't just have one copy of your genome to edit. You'd need to edit the genome in nearly every cell. Or at least all the cells in the primarily affected organ. Because all your cells have their own copy of the genome and all their copies are missing those two genes.

    • @aniksamiurrahman6365

At least across the entire human population, because it's a) not silenced at all in chromosomal men, because that would be lethal and b) only one of the two copies in chromosomal women is silenced for dose compensation. So, the overwhealming majority of X chromosomes on this planet is not silenced.
      But why does it surprise you that most of our genes are usually switched off? I don't think you need your HOX genes anymore after your born, because there's no new limbs that need defining new buds. So, of course they're switched oft, because otherwise they would wreak havoc?
