No such thing. Ask away!

!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.

The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.



Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here.

Seems pretty dumb in our biological design to not be able to regenerate such a functional (and also easily breakable) part of our body.

You’re saying we could reactivate the gene and get infinite teeth?? 🫨

[–] bluGill@kbin.run 46 points 1 month ago (7 children)

Possible, but it may come with downsides you don't like.

[–] sbv@sh.itjust.works 28 points 1 month ago (1 children)

Let me guess, the downside is infinite teeth.

[–] bluGill@kbin.run 8 points 1 month ago

The downside could be something that nobody has imagined yet. That is the problem with change. I'm not against this, but I demand reasonable study. (but not unreasonable levels - vaccines and GMO have been studied enough to conclude they are generally safe despite people yelling more study needed)

Imagine teeth grew like our nails and had to be clipped regularly

worse, you have to pay to stop them from growing

[–] jaybone@lemmy.world 7 points 1 month ago (1 children)

Side effects may include dry mouth, diarrhea, attacking swimmers at the beach. Do not take Teethenall if you are allergic to shellfish.

[–] masquenox@lemmy.world 1 points 1 month ago

attacking swimmers at the beach

That I could live with.

[–] Mongostein@lemmy.ca 7 points 1 month ago (1 children)

Isn’t this the Street Sharks origin story?

[–] jaybone@lemmy.world 1 points 1 month ago (1 children)

Are those the snapping guys in West Side Story?

Vagina teeth? That's my fetish.

[–] TheFriar@lemm.ee 1 points 1 month ago

That sorta makes it sound like a nightmare

[–] themeatbridge@lemmy.world 1 points 1 month ago (3 children)

I could be wrong, but I don't think that's how the drugs in development work. They cause the existing teeth to produce more enamel or something.

[–] originalucifer@moist.catsweat.com 23 points 1 month ago (2 children)

you are wrong. all their tests are on subjects missing teeth, not with reduced enamel. this is literally growing replacement teeth.

[–] themeatbridge@lemmy.world 12 points 1 month ago

I stand corrected. Thanks!

I was thinking of this:

https://dental.washington.edu/trials-begin-on-lozenge-that-rebuilds-tooth-enamel/

But your link is far more exciting.

[–] Rhaedas@fedia.io 2 points 1 month ago

Hopefully that's what it ends up being, as the idea of growing new teeth has been around in science and media for a long time.

[–] Rhaedas@fedia.io 7 points 1 month ago (1 children)

The latest work I've seen reactivates the genes to start growing any existing teeth that had stopped. It's for early development problems in children, not for adults. But of course the media seized on the "regrow teeth" part and ran with it. Unless there's a way to implant new teeth seeds and then get them going, adults are still out of luck.

[–] 5wim@slrpnk.net 3 points 1 month ago

The trial, which will take place at Kyoto University Hospital from September to August 2025, will treat 30 males aged 30-64 who are missing at least one molar.

[–] Slotos@feddit.nl 2 points 1 month ago (1 children)

Teeth cannot produce enamel. Enamel is not a living tissue and it was produced by cells outside of the tooth in a coral-like manner. In order to grow a new tooth, you need it to be fully surrounded by specialized living tissue for the whole growth cycle.

PS: I honestly expected something like this to come out of bioelectric computation research, but progress seems slower there. Or rather knowledge and techniques in other fields is reaching critical mass, giving us these advances.

Maybe "produce" isn't the right word, but I was thinking of these lozenges that made headlines a few years ago.
