Epigenetics: A Journey Through Inheritance Beyond Genes
For centuries, scientists have been fascinated by the mysteries of heredity and how traits are passed down from generation to generation. DNA, the molecule that stores our genetic code, was once thought to be the sole determinant of our characteristics. However, a new frontier in biology, revealing a captivating layer of complexity beyond the DNA sequence itself: Epigenetics.
What is Epigenetics?
The term "epigenetics" was first coined in the 1940s by British biologist Conrad Waddington, but it wasn't until the late 20th century that its significance truly blossomed. Epigenetics, literally meaning "above genetics," refers to the study of heritable changes in gene expression that occur without alterations to the DNA sequence itself. Imagine DNA as the musical score, but epigenetics are the conductor and musicians who determine how the music is played. Through chemical modifications and adjustments to the proteins around DNA, epigenetics dictates which genes are turned on or off, influencing how cells function and ultimately shaping our health, development, and even behavior. Think of your DNA as the hardware: it contains the basic instructions for building and running your body. But epigenetics acts like the software, fine-tuning those instructions and determining which genes get turned on or off at specific times and in specific cells. These modifications, like chemical tags or changes in the packaging of DNA, don't alter the underlying code itself, but they can have a profound impact on how it's read and interpreted.
The Key Players:
DNA methylation: This process involves adding a methyl group to DNA, essentially silencing the gene it's attached to. Imagine it like putting a dimmer switch on a light bulb.
Histone modifications: Histones are proteins that package DNA, and changes in their structure can make genes more or less accessible to the cellular machinery needed for expression. Think of it like adjusting the curtains around a window - open wide for full light, slightly closed for filtered light.
Non-coding RNAs: These are molecules that don't code for proteins but can regulate gene expression in various ways. They're like the backstage crew in a play, ensuring everything runs smoothly.
The Power of Epigenetic Regulation
Epigenetic regulation plays a crucial role in various biological processes, including:
Development: During embryonic development, different cell types emerge from the same DNA blueprint by activating or silencing specific gene sets through epigenetic modifications.
Cellular differentiation: Specialized cells like muscle or nerve cells have unique functions due to differences in their active genes, controlled by epigenetic mechanisms.
Learning and memory: Epigenetic changes in brain cells are thought to be essential for learning and forming memories.
Aging: As we age, our epigenome accumulates changes that can contribute to age-related decline and disease.
Environmental influences: Diet, exercise, stress, and exposure to toxins can leave epigenetic marks on our genes, potentially impacting our health and even the health of future generations.
Epigenetics reminds us that we are not simply products of our genes. Our environment, choices, and experiences leave their mark, shaping who we are and potentially influencing our children's health. This deeper understanding of ourselves opens doors for self-awareness, empowerment, and potentially reshaping our narratives – not just as individuals, but as a species with the potential to leave a healthier legacy for generations to come.

My brain has been full of thoughts about bad boy Wei Wuxian who's really bad at being a bad boy like he feels bad about littering cause it makes extra work for others and he coughs whenever he tries to smoke and a leather jacket is so uncomfortable he misses his hoodie
Like he rolls up on his bicycle (not motorbike he knows Popo doesn't like how loud they are so he rides her old bike instead) and he tries to look nig and tough cause idk he thinks the aesthetic is good but then he sneezes all dainty like cause he's got pollen allergies
Everyone thinks he cuts class cause he's a rebel and delinquent and he's outside up to some mischief but actually he learned it all already and he needs to help babysit A-Yuan so he has to prioritize
Lan Wangji is all Wei Wuxian is so intimidating and probably would never like a goodie two shoes like me meanwhile Wei Wuxian is trying to figure out how to pose sexily next to yellow bike with a basket on it so he can attract Gege's attention
(Naturally in this AU Lan Wangji looks like the biggest need ever we are talking thick glasses pocket square shirt buttoned to the top baggy sweaters, but he's into extreme sports and he's the one with a fancy mountain bike and he goes mountain climbing every weekend)
(his eyesight is too bad for contacts. he has to wear sports goggles like these)
(wwx thinks they're cute)

Jack Marsh (2005), Friendship Otherwise - Toward a Levinasian Description of Personal Friendship
#saw carnation lily lily rose by john singer seargent irl today. it was basically at my doorstep all along idk why i never went to see it#it was placed at a corner in the gallery. me and my friend sat down and sketched the paintings of beautiful naked people quite badly. paper#provided by tate britain. she told me about how she couldnt look her boyfriend in the face after a harrowing film about war. when i say the#interview was informal i mean the person who was supposed to be my boss told me let me get you a cider and then he said after#50 years of life he knows people are inherently good and it only takes a little bit of kindness to save this world. he said he tricked#his wife into keeping the baby and then he said he quit his job at a US bank to help people find meaning and in it#he would have liked to find meaning. instead he started climbing with his friends. he said he chews his cigarettes because its a habit from#when he had to hide things from people. the entire time i felt uncomfortable and incredibly enlightened. this is my friends mentor. she has#his pattern of pauses and expletive and penchant for ends-justify-means attitude. i do think im not very clever#but maybe one day i will love you enough to make up for it. i wrote code i dont understand staring at the final error i thought about how#we both thought of how when we're too old to remember the voices of our friends we would like to stand in the pathway of the LHC beam pipe#cut it open and eat light in the freezing cold vacuum (kills you long before radiation will) the invisible puncture wound unfolding dna#back to the start larger than you ever were. you go to heaven once youve been to hell. my friend is in my bed#practicing calculations of eigenvectors by hand and she is uninterested in a visual proof you are uninterested in incompetence#we catch a train this is your kind of burden you tragic hero wincing at that word you only do this because you have to. im the only one#who can. i am a coward in this for the fucking poetry. the visual proofs. the pretty numbers. an architect who was horrible at maths wanted#to be a philosopher and accidentally ended up neck in deep in 70th Error On Visual Studio Code i want to kiss your eyes before we say#goodbye we both know there is no love in the way there should be. I still have your dress in my wardrobe. i hope you make art.#you think im alright head-wise i think you fucking hate me i think ill never be so clever you want me to tell you my idea?#if you wanted more of this world i would have liked to kiss you harder. we cant both be like this. im sorry i cant be with you the whole wa#the love is gone if you have to ask it. his breath catches his eyes feel stiff it is -1.9 kelvin he is near the beam pipe i miss holding#his hand i miss her singing voice i miss his hair and i found the antonym of pain thank you for carrying me home.

This image that just popped up on my Pinterest feed is a good example of New Agers spiritualizing health conditions that could be anything from regular PMS to shit you talk to a doctor or therapist about:
Tumblr media
"High pitched sounds in the ears" - tinnitus is often harmless in and of itself, but it can be a symptom of serious illness.
Migraines can be set off for many, many reasons, none of which have anything to do with "DNA upgrades." If you suddenly start getting migraines, you shouldn't dismiss them.
Pain in the shoulders can be caused by poor posture/poor sitting position.
Bloating, tiredness, insomnia, cravings, and exhaustion are all PMS symptoms. If they cause problems for you, you shouldn't just ignore them.
Intense and vivid dreams can be brought on by stress and even trauma. If you suddenly start having a bunch of intense and vivid dreams that bother you, don't dismiss them.
To be sure, New Agers have been passing concerning health conditions off as "ascension symptoms" for many years now; they were claiming this kind of stuff was evidence that you were going to ascend to 5D on December 21st, 2012. Considering that nobody ascended to 5D back in 2012, I think it's safe to say that it won't happen this time, either.

A couple years ago I made a tweet about how Samus was transgender and it blew up for some fucking reason. Anyway, as with all big tweets involving trans people, a bunch of people came in with reasons why Samus couldn’t possibly be transgender, none of them really made sense, but the only one I couldn’t outright refute was that we see her as a young girl in the manga apparently.
Anyway, so I’m playing through Metroid Zero Mission and I just finished the zero suit Samus section, which ends with a flashback to when child Samus lives with the Chozo. Right there in the official game I was being shown what young Samus looked like. Do you want to see the “Samus as a young girl that is irrefutable proof she cannot possibly be transgender”?

I would very much like to infoblast about Raven Beak's powersuit upgrade library with all the optimizations, QoL tweaks, security features, and the myriad integration systems Samus is currently lacking with her babby suit, but alas. Time restrictions.

okay but real talk
if m!leven was really, genuinely, unquestionably endgame then there would not be this much doubt and disbelief about it. there would be some, sure, but it would just be a tiny vocal minority like the byler community was before s4. somebody always wants to be contradictory. hundreds of thousands of people don't invest themselves heavily in that contradiction. millions don't feel casually favourable toward it.
it's an undeniable fact that the way season 4 was structured, on many levels, caused a large (large!!!) amount of people to doubt the stability of m!leven. for SO many people to switch over the course of just a month from either favourable to or actively shipping mike and el, to at the very least disliking their relationship and in many cases actively supporting the idea of mike and will instead??? that doesn't happen. it just. doesn't.
it's also an undeniable fact that, having been given an unfavourable perspective on m!leven's relationship by s4, many people have looked back on the previous seasons and noticed in retrospect how both the flaws of their relationship and the strengths of mike and will's have been present since the beginning. s4 didn't change the core of either relationship. all it did was finally strip back the layers that had always been a little transparent and put those cores on full display.
if m!leven was truly engame that wouldn't just mean that s4 was bad and it did such an inadequate job of making people root for its ship that it turned them away; it would mean that the entire show has been terribly written from the beginning concerning only these specific relationships.
it truly baffles me that so many diehard m!leven supporters (or at least, diehard byler antis, and we all know what that's code for😒😒) will happily take that as an explanation. they WANT their show to be badly written, because if it's well written then it's all too clear that the narrative is no longer in their favour. more than that: it never really was.
think about all the other relationships in the show, that fandom and GA alike concur are well written and compelling. think about jonathan and nancy, how the tension between them was evident from the beginning, but nancy was stuck in an increasingly unhappy relationship with steve. think about joyce and hopper, who have had painfully obvious chemistry for the whole show but took until well into the penultimate season to kiss. think about lucas and max, about the growing pains their relationship has gone through and how they only served to strengthen their connection. lumax in particular is the ultimate anti-m!leven, going through the same motions but with a natural chemistry and genuine connection that mike and el have never quite made believable. both the contrast between all three of these relationships and m!leven and the similarities they share with byler have been painfully clear for at least two seasons, and the elements that clash have been built since s1.
all of these relationships have had broad arcs that span across the seasons, and the dynamics have shifted accordingly every time. but mike and el??? their dynamic is the same as it was in s1, on the surface at least. and that's not cute or romantic, as much as the shippers would like to think it is. that's bad for them on an in-universe level and on a writing level as well. a static relationship is never compelling. the writers know this. they have demonstrated their ability to develop relationship arcs in new directions, that are predictable not because they're badly written and trite, but because they're well written and have been foreshadowed and eased into by the narrative whole seasons ahead of time.
if mike and el were truly meant to be, there wouldn't be this clash between them and every other pairing in the show. if mike and el were truly meant to be, their predictability would be like that of jancy, or jopper, or lumax. we know they'll work it out, we know they'll get together in the end, we know they'll grow closer as they grow up.
but, they don't. they don't work out the issues in their relationship. they argue about them, and then they ignore each other, and then they ignore the problems, and then they argue again. and again. and again. they don't get together in the end. if you count their first kiss as the unofficial beginning of their relationship, then they've been together in some capacity since s1. that's a whole season longer than any other endgame couple in the show. they don't grow up together. they grow up separated while el is hidden away, and then separated by tension from their breakup, and then separated by states' worth of distance and all the lies they build up between each other to lengthen it.
if they were "true love" then not only would these issues be either addressed and resolved in a satisfying manner or clearly primed for resolution in the next season, as is the case with the other ships, they wouldn't have been included in the first place. they wouldn't have been strewn throughout the early seasons for later consideration. they wouldn't have been overwhelmingly present in s3, but brushed off as comedy. they wouldn't have been put on full blast in s4 and shown for just what they truly are.
but coming up to s5, the show truly is reaching its climax. none of the relationships have been fully resolved yet. jonathan still needs to come clean to nancy, and nancy needs to let steve down. joyce and hopper still need to have their date at enzo's, and properly establish their relationship. max still needs to wake up, and i'm sure lucas will be responsible in some way for finding her. all of these relationships, however, have mirrored the main plot in their progression toward a climax. they're on the tipping point. if mike's monologue is to be taken at face value and the tension that follows it for the remaining runtime is ignored, el and mike have already reached the climax of their arc. never mind that their problems only continue to fester, unaddressed. never mind that mike and will sit on the same tipping point as the rest: half-addressed, with will's confession hidden in plain sight in the same way his feelings have been all along.
the last points to resolve in both relationships are obvious to us, not because we are "geniuses" for noticing them, but because they should be obvious, just like they are with every other relationship. not now in s4, when they aren't the focus and frankly shouldn't be, when the writers want to preserve one last layer of transparent mystery for the sake of an unbeatable talking point. it will be obvious in s5, when your dad and screenrant and the myriad reaction youtubers will all see as much as they always do: the surface level. and then they'll think back, remember the scenes that flashed by in the season recap. they won't feel decieved then, or even particularly subverted. they'll just see the story that has been told since the beginning. they'll feel satisfied, and if they don't then it has nothing to do with the quality of the writing and everything to do with their own prejudice.

Just to be a menace, I'm here to add to the hunger au asks count. Have you ever talked about grians first instance of going into his true form? And maybe like if the others have ever seen it at some point or whatever
-🌽
You fucking menace ive gotten like 30 asks over the past two days [insert floorbang emoji] im fucking carpet bombing my blog with hunger au content just to make sure i can answer them all, i dont wanna leave anybody out 😭😭😭😭😭😭
In truth, i havent talked about that yet because i havent fully figured out the process on what that looks like or how it works. I can say that nobody has actually seen Grian in true Watcher form yet-- Watchers by nature are very secretive, and Grian spends pretty much all his time camouflaged in his Player form. It's gonna take a while for him to trust anyone with what that looks like, even after he gets back to Hermitcraft
What im thinking right now though is that Watcher "camouflaging" is pretty much surface coding-- so the same way Players can change their appearance with a little code-wrangling, Watchers have learned to mold their physical appearances as well. Takes a lot of time and care, though, because their code structure is so brittle, so i dont see them doing it like, at the drop of a hat. Hence why i dont think Grian has been in his true form in quite some time, and would be very reluctant to try and change back
