Lead the Follower

Computer modelling collective cell migration – such as occurs in wound healing, embryo development and cancer invasion – reveals the contributions to the speed of migration made by characteristics of the cells of the leader and follower rows

Do you believe Lightbearers are changed biologically from before they became Lightbearers?

Can't believe I forgot to answer this- I genuinely thought I did until I was scrolling through my inbox and saw it pop up again. Oops.

Anyways, my headcanon is that yes, Lightbearers are biologically different than non-Lightbearers- they become so when their ghost is rezzing them for the first time. During the first rez, their bodies are essentially restructured to better suit being a vessel of Light, with far greater phsyical resiliance, capacity, and overall durability being granted as a boon from the Traveler so that they're not torn to shreds when using even the most basal abilities. Even Lightless, they're still much stronger than a baseline human, they cannot age (their telomeres simply do not degrade and their DNA repair kit becomes more accurate, so they don't incur the gradual DNA loss/nonspecific remedies that lead to the maladies of old age), and they're still paracausally sensitive, even if their conduit for channeling the Light has been cut. Outside of the never-aging and paracasal-sensitivity thing, the effect isn't drastic, but they are still noticibly hardier than a person who'd never directly touched the light of the Traveler would be. Eris, Zavala, and Osiris could be beaten by a sufficiently strong mortal in an arm wrestling contest, for example, but they're all able to learn to use Darkness/walk off injuries with an ease that a Lightless mortal cannot.

After the first rez, additional permanant change is possible, but it requires either paracausal alteration (such as wounds created by Darkness, wounds that were earned and began healing in a no-light zone, or subconcious paracausal alteration, where the Guardian's own body rejects the touch of the Light), or deliberate ghost manipulation. I like to headcanon that by using the Light in much the same way that they would heal, Ghosts can learn to tweak parts of their guardian's bodies to be altered to their liking, which is a method by which transitioning post-rez occurs, in the instance that one was not an exo or did not medically transition before death. It's extremely delicate, but all they have to do is use their bond and the Light to go 'hey, you're missing something, you need to make more of this hormone or grow more of this tissue to fully heal', and bam, gender transed :) This fully depends on the skill of the ghost, however, so its a slow process even if it can theoretically lead to a full transition over time, and certain tissues can only atrophy so far before they need to be cut off. In the case of exos, all the ghosts need to do is block the mental disconnect between the body alterations and the perception of what those should be, and that's about it

@its-leethee I felt weird reblogging my own huge post for this lmao

I'm totally willing to accept all of that without question (Christian upbringing, I guess?) but what melts my brain out my ears is if Harrow and Viren had swapped bodies, would Viren's dark magic corruption stay with his body, or with his spirit/essence?

I mean, that and "wait why does the coin spell appear to literally draw the spirit out of the body, but then the body also disappears"

This is where the REAL Clone Wars starts.

Seriously though this so weird and it doesn’t sound like good idea…

fun drohnen fact: they love to fight. They will fight eachother for whatever reason but interestingly it actually deescalates most things 80% of the time. Disputes will generally have the two parties beat the crap out of eachother and in the winded daze afterwards they'll come to agreement and for this reason, their politics is insane and politicians oftentimes leap over their counters to beat the shit out of their opponents and nobody does anything about it because, well, it'll probably chill them out OR they'll agree on something.

This is, weirdly enough, probably because fighting is also a little romantic. Since Drohnen residents are all only One Sex and kids are expensive little tots who grow up to be the size of buildings, only one of them have the kid and that is generally decided on whoever loses/falls over (Drohnen pregnancies are WAY less scary than human ones, especially because they're used to laying eggs every 3 months - the loser generally doesn't mind it.).

Sometimes it's seen as a little suspicious when a fight lasts too short since romantic fighting is generally shorter than most fighting. much to the dismay of politicians trying to wrap up a squabble to get back to business

In Superboy 1994 #0, Kon is being examined by Professor Emil Hamilton, who asks him, "Tell me all about yourself, from the beginning! Yes--that'll help context the data..."

"My first memory?" replies Kon. "You won't believe this, Doc, but..."

His first memory dates from while he was still in development (although already physically a teenager, judging from his appearance), and...

Kon's first memory is hearing the word "mother" said. Not regarding his own mother--he of course doesn't have one--but in the context of a joke in a cartoon show that Cadmus wants him to know about for some reason.

This is followed shortly by Westfield (his human DNA donor, pre-retcon) calling him "son" while identifying him as a pawn in Cadmus's scheme to create their own mind-controlled Superman.

Therefore, his earliest memory is of being exposed to distortions of parenthood. "Mother" is a punchline on TV, and his "father" plans to exploit him.

This explains a lot.

no baby for me.

Of the three eggs harvested last week, one has developed into a grade 4AA embryo. I have another appointment in two weeks to do more blood tests, get some more hormone injections, and setup the appointment for the transfer.

Birth Wait

This study of blastoids – lab-grown embryo models – reveals that, like many other mammals, human fertilised embryos have the potential to be dormant (a process called diapause). Insight for interventions towards improving reproductive success

I need the characters I create to stop being smarter than me so I don't have to research things all the time to write dialogue

another reason to play code embryo despite redundancy is you need to experience the "mei is really annoying" to "mei is one of the best written characters in the entire franchise" timeline

[tranakin-skywalker]

Really really really wish sites wouldn't phrase things like "your baby" or "your pregnancy" when describing fetal development. I'm just doing research for a fanfic! This made up fictional character is the pregnant one, not me!
