What did you learn today? Share it with us!

We learn something new every day. This is a community dedicated to informing each other and helping to spread knowledge.

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

Rules (interactive)


Rule 1- All posts must begin with TIL. Linking to a source of info is optional, but highly recommended as it helps to spark discussion.

** Posts must be about an actual fact that you have learned, but it doesn't matter if you learned it today. See Rule 6 for all exceptions.**



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

Your post 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.

Posts and comments 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 non-TIL posts.

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



Rule 7- You can't harass or disturb other members.

If you vocally 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.

For further explanation, clarification and feedback about this rule, you may follow this link.



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.

Unless included in our Whitelist for Bots, your bot will not be allowed to participate in this community. To have your bot whitelisted, please contact the moderators for a short review.

But are there negative ramifications of this mutation?

[–] ArbitraryValue 8 points 2 months ago* (last edited 2 months ago)

I'm not aware of any negative ramifications, but the naming is not a matter of ramifications. This isn't just an abstract change from more body odor to less body odor. Proteins are machines, there's a particular protein machine for moving certain molecules out of cells and into sweat, and in people with this mutation that machine doesn't work. Consider an analogy to a light switch. It's not a toggle between "emit brightness" and "emit darkness". There's a machine on the ceiling for converting electrical energy into light. When the switch is in one position that machine is functioning, and when the switch is in the other position the machine is not functioning. In other words, darkness isn't an alternate way for the machine to function, but rather the consequence of the machine not functioning.

The lightbulb analogy isn't perfect because you could say that the switch and lightbulb together are the machine, and that the function of this machine includes the capability to switch on and off in response to a signal. There are many proteins that can also be switched on or off and they're not "nonfunctional" even when they're "not functioning". However, this mutation doesn't create a protein that can be switched on and off, so I suppose you can think of it like smashing a light which you can't control with a switch. Maybe the light was annoying and you're happier without it, but you still broke it.

For a few months, while I was taking Accutane, my earwax turned dry and flaky. It was awesome. It would come out much more easily, it wouldn't accumulate, and for once my ears stopped producing so much liquid. But I imagine depending on your unique body, it could make things quite a bit worse if you manage to get an earwax blockage.

Disclaimer: do not take Accutane for more than a few months, unless your doctor really knows what they're doing. Apparently there are significant risks associated with long-term usage.

And pure speculation, but I imagine if you're not excreting that fat, you might lose a tiny bit less weight when exercising?

Interesting, but how is that relevant to the question:

But are there negative ramifications of this mutation?

[–] [email protected] 2 points 2 months ago (1 children)

It's speculation, but from my experience with Accutane I can infer the following possibility:

  • an earwax blockage could get worse because of dry earwax depending on the particular ear

Also speculation:

  • if there's fewer lipids in sweat, you keep those fats, and potentially you lose less weight.

At the same time, east asian people are not known for having more trouble with being overweight. But that's probably much more complicated.
