Rules:
1. Be civil
Attack the argument, not the person. No racism/sexism/bigotry. Good faith argumentation only. This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban. Do not respond to rule-breaking content; report it and move on.
2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious biased sources will be removed at the mods’ discretion. Supporting links can be added in comments or posted separately but not to the post body. Sources may be checked for reliability using Wikipedia, MBFC, AdFontes, GroundNews, etc.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source. Clickbait titles may be removed.
Posts which titles don’t match the source may be removed. If the site changed their headline, we may ask you to update the post title. Clickbait titles use hyperbolic language and do not accurately describe the article content. When necessary, post titles may be edited, clearly marked with [brackets], but may never be used to editorialize or comment on the content.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials, videos, blogs, press releases, or celebrity gossip will be allowed. All posts will be judged on a case-by-case basis. Mods may use discretion to pre-approve videos or press releases from highly credible sources that provide unique, newsworthy content not available or possible in another format.
7. No duplicate posts.
If an article has already been posted, it will be removed. Different articles reporting on the same subject are permitted. If the post that matches your post is very old, we refer you to rule 5.
8. Misinformation is prohibited.
Misinformation / propaganda is strictly prohibited. Any comment or post containing or linking to misinformation will be removed. If you feel that your post has been removed in error, credible sources must be provided.
9. No link shorteners or news aggregators.
All posts must link to original article sources. You may include archival links in the post description. News aggregators such as Yahoo, Google, Hacker News, etc. should be avoided in favor of the original source link. Newswire services such as AP, Reuters, or AFP, are frequently republished and may be shared from other credible sources.
10. Don't copy entire article in your post body
For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

My dad had a double lung transplant several months ago...we were told by his transplant team that, with transplants, rejection is a "when", not an "if". However, if caught early enough, the docs can do an incredible amount to combat rejection.
Complete layperson here but it kind of astounds me that we haven't cracked the code for this friend-or-foe identification. One would think there is some identifier or expression that is evaluated by the immune system and if we could match that we'd be golden but clearly not that simple.
We can’t even cure autoimmune diseases yet. Why the fuck has my immune system decided my own tissues are the enemy?! Such a dick move.
Fucking confused white blood cells need to figure out their shit
I started reading the book Immune by the team that runs the Kurzgesagt (In a Nutshell) YouTube channel. The book is written for laypeople like us to understand, but I didn't get very far before going "holy shit this is ridiculously complicated". Honestly, just the fact that scientists understand any of this astounds me.
Rheumatologists are practicing alchemy, I'm convinced.
Years of dedication, my friend.
Surprisingly, things become simpler when there are more eyes looking at them. The more esoteric something is, the harder it will be to grasp because there are fewer resources to help you.
Taking immunology right now, it's incredibly complicated. Immune cells aren't like any other cells in our bodies, they're absolutely bonkers.
Cue The Island, lol
Our bodies are just winging it. It's both beautiful and goodness and all kinds of other things but it's a bit philosophical at times.
I had ITP. Autoimmune something which means they don't know what caused it but my body stopped acknowledging that parts of my blood cell, not the entire one just a piece of it, we're not me. Of course not me gets flushed out.
But the fancy words for part of a blood cell is called a platelet if you don't have any platelets you don't clot. As you can probably pick up not being able to clot is a big problem. I was in danger of bleeding out because my body decided to take out all my platelets.
Seems like an easy problem. If a whole blood cell is me because the DNA matches and all kinds of other things, obviously one cell of me is one cell of me. But if you take one cell of me and you break it up into pieces is it still one cell of me? By definition is not it is 50% of me....
So one cell of me is obviously me and one cell of you is obviously you but what happens when we get into percents at what percent does my cell stop becoming me?
Biology is not as simple as 1s and 0s. We want it too be. But it's just more complex.
Your body has the miraculous ability to identify ANYTHING that isn’t itself: viruses, fungi, bacteria, even lots of nearly-self things like cancer.
It’s likely not a solvable problem.
Oh it is... we just need to get over the idiots that don't like stem cell research. If we could clone and grow our own organs it would be a huge step.
I doubt that.
Fair enough.
These are very complicated processes that are difficult to interpret with such a (relatively) small number of people looking at it.
Honestly, this might sound weird, but if my body ever got to that point, I'd rather just go die in a war.
Better to go out with a bang than a wimper, imo.
Lmao yeah you say that now
