YSK - for all the things that can make your life easier!
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 YSK.
All posts must begin with YSK. If you're a Mastodon user, then include YSK after @youshouldknow. This is a community to share tips and tricks that will help you improve your life.
Rule 2- Your post body text must include the reason "Why" YSK:
**In your post's text body, you must include the reason "Why" YSK: It’s helpful for readability, and informs readers about the importance of the content. **
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-YSK posts.
Provided it is about the community itself, you may post non-YSK posts using the [META] tag on your post title.
Rule 7- You can't harass or disturb other members.
If you harass or discriminate against any individual member, you will be removed.
If you are a member, sympathizer 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.

Would someone here care to share what they know about prions?
So you know how you have dna? Well dna converts into amino acids and long chains of amino acids are called proteins. Proteins are the real workers in our body.
But you might think, if you knew the dna sequence, you know it all, correct? Not really. You see, dna is only 1 dimensional data. A lot of the information about the functions of a protein comes from its structure.
So really, if you have a correct dna converted into amino acid chain (a protein), it still needs to be in the correct shape or folding in order for it to function.
Prions are incorrect foldings of amino acid which obviously do not work. But whats more is that, when these folded structures come in contact with other functioning proteins, they can turn them into incorrect folding as well.
Since these proteins are still your own (ie they still came from your dna) the immune system doesn't quite work on them like it would on a foreign substance like bacteria or virus.
To add to how scary prions are, you can’t really cure them, and when the prions get on a surface, it’s extremely difficult to sanitize that surface in a way that will destroy the prions. A lot of techniques that kill bacteria or even viruses like alcohol won’t work on them. Heat works but you have to make it extremely hot, much hotter than what’s needed to kill something like a bacteria.
I'm glad someone put the prions in here. As a biology student, there was only one thing more terrifying than retroviruses — prions.
I actually read it as "priSons" and I read all the answer wondering how it would get to prisons lol
What if proteins were jerks? Prions.
