A severed mosquito proboscis can be turned into an extremely fine nozzle for 3D printing, and this could help create replacement tissues and organs for transplants.

I've linked to a decent write-up on Tom's Hardware, but New Scientist covered it last week too.

Source paper: 3D necroprinting: Leveraging biotic material as the nozzle for 3D printing (science.org)

Interesting fact: You can use an elephant's trunk as a low-resolution 3D printing nozzle

[–] brown567@sh.itjust.works 3 points 2 hours ago

This one seems about that size

[–] dellish@lemmy.world 2 points 2 hours ago (1 children)

Yes but does it have to be dead at the time?

I'm really not sure why they felt the need to point this out in the article.

[–] crapwittyname@feddit.uk 3 points 34 minutes ago

Yes, the first attempts via the more obvious approach of using a live mosquito were a lot trickier, because the techniques required in persuading the mosquito to comply were outside of the specialist knowledge base of the team. That is, until one serendipitous moment when a heavy-handed researcher accidentally killed a mosquito whilst trying to attach it to a printer. The surprise and elation that must have resulted when they realised they could use mosquito husks must have been a sight to behold. The missing piece of the puzzle had finally fallen into place; some might say by Divine Providence. I daresay some of the project leads were kicking themselves! "It's so simple! Dead mosquito proboscises! Dead! Why didn't I think of that?!", etc. But I think we should go easy on those people, we could all get a doctorate in the field of hindsight!
In the end, just like many discoveries before, penicillin, safety glasses, velcro etc., this breakthrough owes a lot to blind chance.

3D printing is not vegan anymore.

[–] HootinNHollerin@lemmy.dbzer0.com 21 points 6 hours ago

I’m a fan of the flinstones timeline over the techno dystopia

[–] msage@programming.dev 16 points 5 hours ago (1 children)

Aahhh yes, man-made horrors beyond my imagination.

[–] Quetzalcutlass@lemmy.world 1 points 58 minutes ago

This reminds me of a post where someone hooked a dead spider up to a syringe and used it as a grabber. A spider's musculature is hydraulic so the legs would curl and uncurl as the syringe was pressed.

Definitely one of the creepier things I've casually stumbled upon.

[–] Lemming6969@lemmy.world 16 points 6 hours ago (2 children)

There is no way this is more viable than a manufactured micro needle, nor scalable.

[–] some_kind_of_guy@lemmy.world 34 points 6 hours ago (2 children)

Not scalable? You haven't seen my back yard in the summer time, I'm gonna be rich!!

[–] Valmond@lemmy.world 3 points 2 hours ago

He said: I'm gonna be rich!

But all he got was an itch 🎶

[–] Chais@sh.itjust.works 3 points 4 hours ago (1 children)

Keep in mind, you can't such squish them.

[–] some_kind_of_guy@lemmy.world 3 points 3 hours ago

Yeah yeah, we'll figure that out, but first let's talk about that first round of VC funds, right?

[–] squaresinger@lemmy.world 2 points 4 hours ago

It is not. This is just yet another piece of garbage science made to get into headlines, nothing more or less.

[–] 9488fcea02a9@sh.itjust.works 16 points 7 hours ago (1 children)

So these 3D printed things arent vegan?

[–] Sterile_Technique@lemmy.world 9 points 6 hours ago (1 children)

Mosquitoes are an exception to the values typically exhibited in veganism.

[–] some_kind_of_guy@lemmy.world 5 points 6 hours ago* (last edited 6 hours ago) (1 children)

Say what? Is this not exploiting an animal, or worse, creating a potential market incentive to further exploit animal bodies and life? I'm not even vegan. I know individuals have exceptions, and the philosophy is a spectrum rather than a monolith and all that, but are mosquitoes not animal life?

[–] Lemminary@lemmy.world 15 points 6 hours ago

I think they were joking.

[–] gedaliyah@lemmy.world 27 points 9 hours ago

And here I've been throwing away all my dead mosquitoes like a sucker.

[–] MushuChupacabra@lemmy.world 76 points 11 hours ago (5 children)

I'm only in favor of this if the mosquito suffers mightily somewhere along the process.

[–] Cybersteel@lemmy.world 3 points 4 hours ago (1 children)

One almost killed me. Dengue.

[–] argarath@lemmy.world 2 points 3 hours ago

Good news! Brazil developed a single dose vaccine against dengue!! I don't know when they're going to start vaccinating, but the vaccine has been approved, it's already tested and everything!

[–] Imgonnatrythis@sh.itjust.works 26 points 10 hours ago (1 children)

I want it setup so the hot filament goes into its asshole and then out through the probiscus.

Now there's a mental image.

[–] Nurse_Robot@lemmy.world 17 points 9 hours ago (1 children)

The process does involve gaslighting and lying to their mosquito family

[–] meco03211@lemmy.world 15 points 8 hours ago

No no. I want them to know it was me.

[–] Deebster 8 points 11 hours ago (2 children)

I'm currently living somewhere hot enough that the little pricks are a bother all year round.

[–] Bo7a@piefed.ca 4 points 3 hours ago (1 children)

I'm currently living in Canada where the ground has been hidden by snow for a month.

i was bitten by a mosquito outside yesterday.

They are getting stronger.

[–] caseyweederman@lemmy.ca 1 points 18 minutes ago

I'm currently living in Canada and we've seen two snowflakes this entire winter (they fell in October)

Why ja vol? Either ja, voll or jawoll.

[–] lemmyout@lemmy.zip 23 points 9 hours ago* (last edited 9 hours ago) (2 children)

I like how the title specifies the mosquitos are dead. Otherwise I would have imagined a swarm of mosquitos trained to perform like some cartoon.

[–] muusemuuse@sh.itjust.works 15 points 9 hours ago

There is a 3d printer hotend called the mosquito. The company behind it is incredibly litigious. It’s why literally the entire community hates them.

[–] WindyRebel@lemmy.world 7 points 8 hours ago

Probably something from The Flintstones.

[–] veeesix@lemmy.ca 30 points 11 hours ago

Necroprinting is the new Necromancer skill upgrade I’ve been waiting for.

[–] nyan@lemmy.cafe 12 points 11 hours ago (3 children)

Ugh. I hope that there being a use for the little bastards now doesn't make people breed them on purpose.

[–] some_kind_of_guy@lemmy.world 7 points 6 hours ago* (last edited 6 hours ago) (2 children)

I did not have GMO mosquitos bred for a more effective proboscis escaping into the wild on my bingo card

[–] bluesheep@sh.itjust.works 1 points 2 hours ago

Imagine looking down and there's a mosquito printing a fucking benchy on your forearm.

[–] Nighed@feddit.uk 1 points 4 hours ago

Even splatted on the back of it?

[–] Deebster 8 points 10 hours ago (1 children)

Have you seen the footage of scientists feeding them from their own arms? Nooope, not for all the tea in China.

[–] CentipedeFarrier@piefed.social 3 points 5 hours ago

If it makes you feel better, the people who stick their arms in aren’t allergic to mosquito bites. Doesn’t bother them to get bit beyond the feeling of being bit.

I mean I guess it could happen that they are just masochistic, but typically not.

[–] cmnybo@discuss.tchncs.de 1 points 9 hours ago

I hope not. Around here, you just step outside and there will be a dozen swarming around you.

[–] muusemuuse@sh.itjust.works 5 points 9 hours ago

Dude, that’s metal.

[–] fubarx@lemmy.world 3 points 8 hours ago* (last edited 8 hours ago)

I challenged my family not to say WHAT! when reading that headline. So far, everyone's failed (including myself).
