3D printing.
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.

Everything going on in biology, but the existence of of Nana and Lulu especially. The first genetically altered humans are starting school pretty soon.
Say what now?
Google says the twins plus one other 1 yr younger child child were edited embryos using crispr to prevent them from getting HIV from their father(s). Which was and is unethical. They are supposedly doing fine.
Damn that’s crazy. On the one hand, that’s really awesome that we can make it so that the kids don’t have HIV. On the other hand, I worry about people using it for really bad things… Thanks for telling me about it.
Yeah, the dude just kind of went rogue. One of them was fully edited, while the other has a blend of original and altered cells, because surprise surprise China’s maddest scientist did a bad job. If they’re still doing well that’s good, because it wasn’t certain there would be no side effects.
I’m glad they and any kids they have will be around whenever we start discussing doing it properly. And yes, Dr. He Jiankhui went to jail.
Driverless cars, VR and the recent NASA experiment where four people started living in a simulated Mars environment for an year, even conducting VR space walks - all of this makes me feel we’re living in the movie Total Recall.
Get your ass to Mars!
Usually total recall reminds people of something else

Wow, I hadn’t heard about that. I’ve wondered for a while if astronauts could use VR to “escape” a cramped spacecraft.
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.
Thanks for sharing this I always wondered where they got those pictures.
Quantum computing is a very very revolutionary innovation. Biological computers are also going to be very revolutionary.

Both work with “Sync for Lemmy”. Don’t know about other apps/sites.
Thankyou! I can also confirm that both work for me in voyager as well.
Should really be using the “! link”, not URLs. While both work on mobile apps, on the web version the URL redirects to the community’s instance.
Alright, thank you. Good to know!
Someone else here mentioned the Steam Deck as a powerful handheld on the go, I want to do a similar approach.
Playing PS1 games with a Miyoo Mini, I swear my child’s dream was to play PS1 games in a handheld sized similar to my Game Boy Advance from that time, now we can do it in even smaller devices! (And this one isn’t even the tiniest lol).
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)
Data compression. Something about “making less data out of … The same data” is really mind blowing, & the math is sick
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

Don’t overthink my example, it was just a representation

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.
Smartphones. The sheer fact that we’re able to fit these cameras, computer chips, and everything else into these thin glass slabs is still mind-blowing to me.
Even just the screen is absurd.
The DNS it’s so mind blowing to think about how we are able to map so many domains to so many ip adresses so smart and stable
Funny you should say that. DNS is 40 years old. Definitely not futuristic tech. But yeah, it works surprisingly well.
Yeah, still it feels futuristic
And that the service replies practically instantly every time no matter which domain you choose.
Edit: wtf is with these downvotes? DNS is without a doubt the fastest part of accessing the internet. In website load time, it’s an almost unnoticable fraction of the total load time.
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.
Lithium polymer batteries that make advanced computing portable. We wouldn’t be able to create multi function cell phones without the battery power and longevity of those batteries. Star trek tricorders are going to be the next big tech coming to the generation after Gen z.
Tricorders are 70ies tech. 2000s dumbphones are more advanced.
You’re thinking of their com badge, the tricorder was the thing they flipped open to analyse a rock or reverse the polarity of a time crystal. It could do basic medical work, interface with electronics, detect life forms, determine if plants are edible, all sorts
Oh. Yup, my bad.
Yes, I love carrying potentially explosive batteries in the pocket…
I hope you also love driving an actual explosion. Also known as a car.
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.
Guess what? You’re wrong on all points. Studies show that you have 5G Corona and should report to Bill Gates immediately.
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 😘
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?
Fun fact: EVs are much less prone to fire than gas cars, but when a gas car burns, it doesn’t make the news, so public perception is skewed.

Firefighters often submerge the vehicle for weeks or else it would reignite…
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?).deleted by creator
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 don’t mean to sound ungrateful, but wake me up when we’ve got replicators and holodecks. They’re as enticing now as they were decades ago.
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.

We have phones as powerful as computers in our hands when 20 years ago that was impossible. The exponential growth of computers and smartphones is mind-blowing. And the amount of technology that has bloomed from all of that
