    The technology behind it isn’t new, but The Thought Emporium is a Youtuber who:

    1: DIY-d a genetically modified virus to cure his own lactose intolerance (successfully)

    2: Is currently working on a biological computer that runs on animal neurons.

    3: Has livestreams where the viewers submit ideas (like making tomatoes spicy) and he designs DNA to accomplish it.

    Also he helped shut down a scam health product that contained radioactive material which isn’t particularly futuristic (actually it reminds me of the “radiation is good for you” craze in the early 20th century) but I wanted to mention it anyways.

    Every time I think about doing something illegal or hear about people from only a few generations ago doing something fun but slightly illegal.

    Then I think. There is no way you could do that now the police would use all the surveillance that is everywhere and if I got caught their wouldn’t be a slap on the wrist and grow up. But it would be a serious issue for my future jobs and going to other countries.

    Makes me think I’m in a futuristic movie. Just not one of the happy ending ones.

    Turns out we can express most of proteins, some of the time, and then isolate them. This includes enzymes, when isolated these can do things like they naturally do but now in flask, but also they do things that aren’t remotely natural but are useful for us. These things are pretty fragile usually so then some of these can be modified so that they are resistant to higher temperatures, detergents etc. This is not only the nerdy shit like advanced chemical synthesis - lots of dishwasher tablets and and washing powders contain enzymes that cut proteins into pieces (like subtilisin), so in some cosmic sense dishwasher digests your leftover food off plates

    Enzymes are still proteins, and have all problems of proteins. Turns out, you can just take the most important part out of enzyme, make it, or something functionally similar out of completely synthetic parts, and it still works. Sure, it’s not as active or selective, most of the time, but it’s resistant to things that would absolutely shred proteins. This is called organocatalysis and it was subject of 2021 Nobel Prize

    Sometimes you want to take an enzyme and make it not work. We also have a tool for that: first you have to get structure of that enzyme, or some receptor protein, and by looking how a small set of random molecules lodges in it you can make a very selective, very potent ligand, sculpting it atom by atom with no knowledge other than protein structure. If you have time and resources, this can be made to work for almost any protein (that can be crystallised)

      I’ve had a 3d printer for years and I still can’t really get over how nuts it is. Like it feels like one of those things you’d read about in science magazines as this amazing super scientific thing the scientists out in MIT have in their labs like a supercomputer or some expensive toy people who build stuff on YouTube have in their garage next to the lathe and big fancy CNC table, but no, it’s just, here. On my desk. Being used to casually print stuff that I’ve designed myself on the computer like it’s nothing.

      My great grandad was a carpenter and I wish I could’ve shown him it. I wonder what he’d think, seeing something that was once only in the realm of handcrafted diagrammes and days of building now a few hours of modelling and printing away.

    The LANDSAT program. Not exactly new since it’s been going for about 50 years, but it’s still fascinating and maybe more relevant than ever with concerns about climate change.

    We can get different types of data about a landscape from the different parts of the light spectrum. For example, telling coniferous and deciduous trees apart based on how they reflect light. Imagine echolocation on steroids, using light.

      It is not that complicated, to make a simple example with strings: AAAABBBABABAB takes up 13 spaces, but write (compress) it like 4A3B3AB take up 6 spaces compressing it more than 50%.

      Now double it like AAAABBBABABABAAAABBBABABAB with 26 spaces and write it as 2(4A3B3AB) with 9 spaces it takes only 30% of the space.

      Compression algorithms just look for those repetitive spaces.

      Takes those letters and imagine them being colored pixels of a picture to compress a picture

        Once you get into audio, images and video it revolves a lot around converting temporal and/or positional data into the frequency domain rather than simple token replacement.

        Wait, isn’t your first example goes from 13 spaces binary to a 6 spaces of base 12 (base 10 + the two values A or B).

        That would make the “compressed” result be 110111010111011101110011 which is larger than the original message when both are in binary…

            Fair enough. The general idea is correct, I just found that example rather jarring… It is generally more difficult to compress an already small amount of data anyway.

        If you lived in a society that had ready access to replicators and holodecks, you’d probably be asking for teleportation and eternal youth.

        What’s amazing yesterday is boring today. That’s kinda part of the human condition.

        Being able to fly anywhere in the world with almost zero planning, and then being able to communicate back to anyone at home with almost zero delay, would have been unheard of just two generations ago, but now that it’s normal, it’s a shrug and look for the next thing.

          If you’ve got replicators, you already have half of a teleporter, and you already have the technology necessary to fabricate replacements for failing body parts, so you’re already at least partway to teleportation and eternal youth.

          Also, I actually had a vehicle from 1987 that totally flooded the cylinders with gasoline due to a fault in the carburetor, and even then it didn’t explode when I started it.

          Seriously though, what’s up with these EV’s that’ll just as soon randomly burn your garage and house down while you’re asleep and the car isn’t even running?

              Yes, that’s true… But on the other hand, it’s much harder to deal with EV fires because a reasonable amount of water won’t put it out like normal fires and it will burn for a long time, and spontaneously reignite after the fact as well. Firefighters often submerge the vehicle for weeks or else it would reignite…

              Mind you, I still prefer EVs over ICE vehicles because the benefits vastly outweigh the costs, but the EV fires are harder to deal with.

              This is why we should do away with personal cars in cities all together and develop better transit systems that are efficient and safe.

                I would like to see a source on that. Because I’ve talked to firefighters who said EVs can be put out like any normal car, you just need much more water.
                Which is a problem, because it means you need to call a bigger fire truck or maybe even multiple for an EV fire, but I’ve never heard of an EV needing to be submerged for weeks (how would that even work?).

            Liquid gasoline is not what will explode. You need vapors. Gasoline still requires oxygen to burn, so if air is not mixing with the fuel, nothing’s gonna happen.

            An internal combustion engine relies on having an environment of maximum flammability in order to function correctly. It’s when that environment is no longer contained by the engine that you run into catastrophic problems. Multiplied by how empty your fuel tank is.

              This is quite true.

              Still, gasoline doesn’t have a tendency to up and spontaneously combust all on its own, it takes some sort of external spark or flame to ignite.

              Lithium batteries play a different game of Russian Roulette though. The car doesn’t even have to be running for one worn out cell to overheat and cause a catastrophic chain reaction blowing the entire battery pack.

          I wish you people would actually do a comparison between ICE engine explosions vs. EV explosions.

          Guess what? Firefighters can actually put out ICE vehicles, but they still haven’t figured out a solid way of putting out EV batteries.

          Guess what? When ICE vehicles explode, more often than not they’re already running and there’s some electrical short or something. EV will just as soon explode in your garage while you’re sleeping.

          Guess what? Studies show that since EV’s are way heavier, they wear through tires way faster? Did you know it takes approximately one barrel of crude oil to make an average car tire?

          Guess what? Autonomous vehicles seem to have a habit of getting confused around emergency vehicles and causing wrecks, into the very vehicles meant to save people from accidents.

          Guess what? Lithium ion batteries are typically rated for a max safe temperature of around 40⁰C, while the pavement the battery sits right over can be over 80⁰C

          I’m too lazy to look up links, you’re smart, go Google these things or whatever. All these facts check out.

            I happen to know a bit about the subject and all of your points are misleading to the point of being completely wrong. Except for the point about autonomous cars, which isn’t really a point about EVs at all.

            I don’t need to Google, but telling people to Google to prove your own point is always laughable. But since you didn’t provide any sources, neither will I 😘
