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

[–] kami@lemmy.dbzer0.com 12 points 7 hours ago* (last edited 7 hours ago)

More interesting facts: you can use a human penis as a medium-resolution 3D printing nozzle

[–] brown567@sh.itjust.works 9 points 11 hours ago

This one seems about that size

[–] dellish@lemmy.world 6 points 12 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 9 points 9 hours ago* (last edited 2 hours ago) (1 children)

Yes, the first attempts via the more obvious approach of using a live mosquito were a lot trickier, because the techniques involved in persuading the mosquito to comply were outside of the highly-specialised knowledgebase of the team. That is, until one serendipitous moment when one particularly 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 was, surely a sight to behold. The missing piece of the puzzle had finally fallen into place. Some might even say... by Divine Providence, perhaps?
I daresay some of the project leads were kicking themselves nonetheless: "It's so simple! Dead mosquito proboscises! Dead! Why didn't I think of that?!", etc. But I think we should go easy on them; we could all get a doctorate in the field of hindsight!
In the end, just like many discoveries before it: penicillin, safety glasses, velcro etc., this breakthrough simply owes a lot to blind chance.

3D printing is not vegan anymore.

[–] GreyEyedGhost@lemmy.ca 6 points 2 hours ago

I'd say harming mosquitoes (females only, that feed on blood) is better than vegan!

[–] msage@programming.dev 28 points 15 hours ago (1 children)

Aahhh yes, man-made horrors beyond my imagination.

[–] Quetzalcutlass@lemmy.world 7 points 10 hours ago* (last edited 6 hours 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.

Edit: Behold, necromancy! (time-stamped video)

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

[–] Lemming6969@lemmy.world 22 points 16 hours ago (3 children)

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

[–] Corkyskog@sh.itjust.works 3 points 7 hours ago

If you scaled it, it wouldn't be high-resolution anymore.

[–] some_kind_of_guy@lemmy.world 45 points 15 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 6 points 11 hours ago

He said: I'm gonna be rich!

But all he got was an itch 🎶

[–] Chais@sh.itjust.works 4 points 14 hours ago (1 children)

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

[–] some_kind_of_guy@lemmy.world 4 points 12 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 5 points 14 hours ago

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

[–] MushuChupacabra@lemmy.world 93 points 20 hours ago (5 children)

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

[–] Imgonnatrythis@sh.itjust.works 35 points 19 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.

[–] Cybersteel@lemmy.world 7 points 14 hours ago (1 children)

One almost killed me. Dengue.

[–] argarath@lemmy.world 6 points 12 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!

[–] Nurse_Robot@lemmy.world 19 points 18 hours ago (1 children)

The process does involve gaslighting and lying to their mosquito family

[–] meco03211@lemmy.world 17 points 17 hours ago

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

[–] Deebster@infosec.pub 9 points 20 hours ago (2 children)

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

[–] Bo7a@piefed.ca 7 points 13 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 9 hours ago (1 children)

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

[–] Bo7a@piefed.ca 1 points 7 hours ago

Lucky.

We have had full snow cover since mid-october here. But it has also been +3-5c most afternoons.

Although early snow often means warmer winter. And I can definitely handle the snow in QC better than the -40s I used to get in AB.

Why ja vol? Either ja, voll or jawoll.

[–] 9488fcea02a9@sh.itjust.works 19 points 16 hours ago (1 children)

So these 3D printed things arent vegan?

[–] Sterile_Technique@lemmy.world 12 points 16 hours ago (1 children)

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

[–] some_kind_of_guy@lemmy.world 5 points 15 hours ago* (last edited 15 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 18 points 15 hours ago

I think they were joking.

[–] gedaliyah@lemmy.world 32 points 18 hours ago

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

[–] lemmyout@lemmy.zip 24 points 19 hours ago* (last edited 19 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 16 points 18 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 8 points 18 hours ago

Probably something from The Flintstones.

[–] veeesix@lemmy.ca 32 points 20 hours ago

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

[–] nyan@lemmy.cafe 12 points 20 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 15 hours ago* (last edited 15 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 11 hours ago

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

[–] Nighed@feddit.uk 1 points 14 hours ago

Even splatted on the back of it?

[–] Deebster@infosec.pub 8 points 20 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 14 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.

Dude, that’s metal.

[–] fubarx@lemmy.world 3 points 17 hours ago* (last edited 17 hours ago)

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