This is where the REAL Clone Wars starts.

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

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

Synthetic human embryos - yeah, now *that's* not controversial...

The synthetic embryos – only days or weeks old – could help researchers study the earliest stages of human development and explain pregnancy loss.  Nobody is currently suggesting growing them into a baby. https://www.bbc.com/news/health-65914934 Well, that’s a relief…. This is the first time that has been achieved using human material. Although, they are not truly “synthetic”, as the starting…

Getting Pounded by Nagas PART 3: Contractions

Pairing: Two nagas x human reader

Summary: You wake up feeling pains in your belly, getting ready for the egg birth. The doctor checks on you there is an issue… one that can be resolved only with your mates’ touch and seed.

Warnings: minors don't interact, 18+!!!!, monster smut, inaccurate pregnancy stuff (this is naga egg preg smut, let me have fun), naga smut, double 🍆🍆, double penetr, lots of come. Don’t like, don’t read please.

This is part of a series. Find all the parts here.

It was early in the morning when the contractions jolted you awake. The bedroom was still and dimly lit only the weak rays of the sun filtering through the curtains. You winced and disentangled yourself from between your mates, clutching your swollen belly and taking shallow breaths. The eggs shifted inside you, the pressure too much. Your groaned and the soft sound stirred your mates from their sleep. They woke with gasps of concern.

“What’s wrong, little one?” Ragnor asked, his fingers cradling your belly. You were 12 months along, so close to birth, your stomach round with the two eggs inside you.

“Contractions,” you breathed as another pain rolled through you.

At your words, both of your mates exchanged a look of worry. You were not supposed to have contractions. A Naga pregnancy didn’t have sudden contractions. It was completely different to a human pregnancy. The birth, too. It was the reason you’d arranged everything with the doctor and planned an induction of labor a week from now. But clearly, that plan would change.

“I can feel the eggs moving,” you muttered. “It’s starting to hurt.”

That’s was all you needed to say before your mates sprang into action.

Ragnor prepared everything you would need, packing you bags and a light meal. Meanwhile Thorne helped you take a shower and put on a soft, comfortable dress. In just twenty minutes, you found yourself lying at the padded chair in the Superhuman Maternity and Birthing Center. The room was bright and serene, the smell of disinfectant in the air. Your mates stood on each side of you, their tails wrapping around the chair.

Dr. Elise, a human woman in her fifties entered the private room, dressed in pristine white robes. She was a very kind and experienced doctor who monitored your superhuman pregnancy. Unlike you and your mates, Dr. Elise was calm upon hearing that you had contractions. She reminded you to keep taking deep breaths and trust in her ability to keep you safe.

“Good, very good,” the doctor said once you had calmed down a little. “Let’s take a look at you and the eggs. ”

The doctor used various advanced technological devises to scan your belly, take some blood samples and check the position of the eggs. You waited patiently as she analyzed your samples, winching only slightly when another contraction hit. Thorne and Ragnor stood at your sides, concealing their concern, each of them holding one of your hands tightly.

When Dr. Elise finally completed her calculations, she looked at you and your mates with a reassuring smile. “Everything appears perfect apart from the contractions. Naga pregnancies don’t cause traditional human contractions. That is because the eggs do not implant in the uterine wall like typical mammalian embryos. Instead, they remain free-floating within a specialized sac that develops to accommodate their growth. What you are experiencing now are false contractions.”

“Are my babies okay?” you asked her, tears pricking at your eyes.

Thorne kissed your sweaty forehead while Ragnor your lips. “We’re right here, love,” each of them murmured to you. “We won’t leave your side, relax for us.”

The doctor placed a strange cylindrical LED device over your vagina and ass, “I see that you’re not filled enough with your mates’ seed. It’s why you’re experiencing contractions and pain. We need to make sure you’re completely suffused in seed, and after that, it’s imminent that they be delivered. When was the last time you’ve had intimate relations with your mates?” The doctor asked you.

“Last night,” you answered in one breath.

“We fucked only once because she was sleepy,” Ragnor said, brows furrowing. “Wasn’t that enough?”

Dr. Elise shook her head. “Not in the least. The eggs consume the seed incredibly fast, especially at their current growth,” she explained. “You’ll need to fill your mate again, thoroughly and immediately.”

“Right now?” You asked, your voice pitching without meaning to.

“Yes,” Dr. Elise said. “I want you to be suffused with seed and after that I’ll induce the birth. We can’t risk waiting and risking both your health.”

“We’ll fill her. In both holes, just to be sure,” Ragnor said, his face completely serious.

Dr. Elise nodded. “Yes, and if you can give her seed through the mouth as well, that would be ideal.”

You flushed furiously as your mates and the doctor discussed the details, their faces dead-serious as if talking about filling your holes with seed was the most casual thing in the world.

Dr. Elise noticed your discomfort and smiled gently. “I want you to trust in me and my abilities to bring your babies to the world. Naga birth requires the assistance of the partners even more so in your case because you’re human.”

“Will it hurt as much as a human birth?” you asked, heart palpitating.

The doctor smiled. “No, it will be pleasurable and just mildly uncomfortable.”

You flushed at the word “pleasurable”. You’d discussed the birth plan a long time ago and you remembered the doctor telling you that your mates would need to make you climax during the birth for each egg to be delivered.

“Let me remind you how this will go,” Dr. Elise began, her voice calm. “Once you’re properly suffused with seed, I will give you a medicine that will induce the eggs to come out. Naga eggs have a tendency to like it in the womb and at some cases, they refuse to come out. The eggs will naturally leave your system, do not doubt that. I have specific instructions for that. Trust me, we will go through with it after you’ve been suffused with enough seed.”

“Thank you, doctor,” you said, your cheeks blushing a little.

“It’s my pleasure. Naga birth is completely different from that of a human so I want you to be as comfortable as possible and talk to me and your mates.”

“I understand,” you said. You trusted Dr. Elise and knew she was right. “Where can I and my mates… uhmm… do what we need to do?”

Dr. Elise stood up. “This room is reserved for your birth so you can stay here. I’ll step out to give you privacy and return roughly in two hours. Call me for whatever you need; I will be on standby.” The doctor headed to the door and glanced at your mates, “Remember, you need to fill her completely otherwise her health and the eggs will be at risk. I’ll come back to check, and if it’s not enough, you’ll have to keep going until the eggs have consumed enough seed.”

Once the doctor was out, you slumped back in the chair. “I can’t believe this. My health is dependent on your seed.”

“Lots of it”, Thorne added, looking smug.

“I’m going to be super cocky about that in the future,” Ragnor said, a smug grin on his face.

Two throaty chuckles made you look at your scaled mates. Horny bastards, they had already dragged off their shirts and their cocks had emerged from their protective slits, thick and massive, the cockheads glistening with arousal. You licked your lips and swallowed thickly. This was real. You were about to be fucked right there, in the examination room.

Ragnor wasted no time and slid up your dress, the only piece of clothing you wore. He left you completely naked on the chair, his hungry amber eyes devouring your form. Thorne was gazing at you just as intensely, both your nagas marveling at your swollen breasts, your round stomach and between your legs. You tried to close them, suddenly a little shy, but their tails wrapped around your ankles, keeping them spread wide for them.

“Will you trust us to fill your pretty little holes, little mate?” Thorne asked, his voice a whisper as he claimed your lips.

“Hnnn… fuck, yes,” you said, arching your back, offering yourself to them. The more they touched you, the more the contractions eased, pleasure taking over.

“Damn, what a pretty sight our mate is.”Ragnor lowered his head to your stomach, rubbed the swell, and spoke, "We’ll meet you soon, little ones. Stay safe and warm in there."

“Daddies will take care of mommy,” Thorne drawled, his mouth finding its way to one of your nipples, drawing it into his mouth. It leaked milk and with a groan he lapped it up.

Ragnor lavished attention on your other breast, his fingers teasing and rolling the tip that was beaded with milk. A whimper came tumbling from your lips then a drawn-out moan as they took turns worshipping your leaking breasts.

"Ahh— hnng... need your seed," you rasped, carding your fingers through their silky long hair.

"We need to prepare you mate,” Thorne said while kissing one lush rosy nipple and wetting the other with his tongue.

"I’m ready... ahh... I need your load."

Ragnor hummed. “Our mate is right. We need to fill her tight little holes. Hm?”

Thorne agreed, a smug grin playing on the lips.

Gently, you were lifted and placed onto Ragnor’s embrace. He carried you to the bed nearby and sat with you against his chest, your sensitive breasts leaking. His massive cock throbbed against your belly, slick with precum as you reached out and wrapped your hands around it. With sensual strokes, you pumped him up and down, the intimacy between you and your mates heightening.

You sensed Thorne presence behind you, his sinuous tail reaching for the bottle of lube in one of the drawers. You heard the slurp of lube then felt him take his place behind you, his cock wet against your back. With your free hand, you reached back to stroke his cock while his lubed fingers deftly parted your asscheeks, spread them wide, fingering your tight entrance and rubbing the swollen nub of your clit.

Thorne thrust a finger into your ass while stroking your clit with the other hand. Your thoughts turned into mush and you buckled your hips, the sensations electric. Another finger slid up your tight hole, the hand at your pussy moving with deliberate movements. You gasped and came with the most ridiculous moans, soaking wet and aching for more.

Sensing your need, your mates lifted you, their cocks poised beneath each quivering hole. Ragnor’s double cocks parted the folds of your pussy, his massive veined dicks thrusting upwards. Thorn’s shafts pressed insistently against the tight bud of your asshole. They guided you down until you were doubly impaled by their dicks.

Breath hitching, you squeezed your eyes shut.

You saw stars.

Pleasure and bliss.

They began their rhythmic thrusts and you whimpered, clutching onto their shoulders for dear life as they bounced you up and down on their naga dicks. Your body hummed with pleasure, the contractions barely catching your attention. Your nipples were hard and leaking, your holes clenching and unchecking around the invasions.

Your mates kissed your lips, your neck, your sensitive nipples. Their fingers roamed protectively over your belly, teasing and claiming you as you rode higher and higher. You rocked against them and rode them wildly, your juices leaking down your thighs and all over the cotton sheets.

Two more thrusts and you came crashing around their cocks, relief surging through you. Your naga mates groaned and followed the very next moment, their frames shaking violently as they spurted their seed inside you. The warmth filled you up, bringing immediate relief as the eggs seemed to settle within you.

“That’s it, such a good mate for us,” Ragnor murmured, kissing you softly. “How are you feeling, mama?”

“Better. Much better,” you said, your eyes and voice pleasure-hazed.

“It'll be okay," Thorne whispered into your ear. "Now we’re going to change positions and fill you up again, alright, love?”

You nodded, whining. You’d do anything to keep your eggs safe and you loved and needed your mates just as much.

“Let us take care of everything, love,” Ragnor said, kissing you softly once more.

A wet squelch echoed as the cocks exited your depths. Your mates held you in a way that kept most of their seed inside you, and quickly plugged you up. This time, Ragnor laid down, thrusting his dicks up your ass, while Thorne slid between your splayed legs, draped them over his green-scaled tail and filled your tight pussy. Their tails coiled around your breasts, squeezing them delightfully and making your nipples leak out milk. Thorne lapped it up greedily, while Ragnor reached down to play with your swollen clit.

“Haah, yessss, ahnnn, feels so good,” you moaned as you were worshiped and claimed in every way possible. “Hng-go…go…nna—”

You cried out at the dizzying explosion of yet another climax. Your toes, high in the air, curled tightly, and your hands clung frantically to Thorne, fingers digging into his bare back. Their movements grew frantic, desperate until they buried themselves to the hilt and exploded within you, pumping rope after rope of cum, groaning harshly in masculine satisfaction.

Their strong hands rubbed your belly possessively, feeling the gentle movements of the eggs inside you. They kissed you deeply, tongues intertwining, then rearranged your positions again. This time, you lay on your side between your mates. Thorne spooned you from behind, his tail wrapping around your knees and opening your legs. Growling, he thrusts his fat cocks into your pussy and ass. You were drenched, naga seed all over your mound and thighs.

“I say we fill her pretty mouth, too,” Thorne said, his voice thick with arousal. “I want to see her swallow your seed Ragnor, let it fill her stomach.”

Ragnor groaned and kneeled at your face, his cocks jutting proudly up to his bellybutton. “Open up, love,” he cooed. “We need to make sure you’re completely filled.

Ragnor guided his cockhead to your lips and you opened up, taking one of his dicks as deep as you could in your throat. You suckled his shaft with fervor, your tongue tracing the veiny ridges and swirling over the flared head. Your hands pumped his second cock and you alternated between the two while Thorne pounded into you, causing your tits to bounce.

“Fuck, you have no idea how beautiful you look, mate,” Ragnor muttered, watching your mouth, now filled with both his cocks, while Thorne’s dicks pistoned inside you.

“Mffgh— love—hffuh you,” you gurgled around the shafts in your mouth, wet slurping sounds filling the room.

“We love you, too, precious mate,” Throne said, hips snapping repeatedly, driving his shafts deep in your depths. “You’re doing great. We’re almost there. Just a little more, love.”

They settled into a sensual rhythm, Ragnor’s cock filling your mouth while Thorne thrust inside your pussy and ass, his hands gripping your hips to keep you steady. They whispered sweet nothings, their voices thick with praise and adoration: ”you’re doing so well”, “our brave, beautiful mate”. They caressed your tummy, pinched your breasts while their tails flicked your poor clit.

Little sparks of fire sizzled through your body and burned you up in a blissful climax. You trembled and writhed, and Ragnor withdrew his cock allowing you to cry out with ease. Thorne’s magnificent serpent body bucked and he came with a bellow, nipping at your shoulder while pumping his seed inside you. Once he was done, Ragnor slid back in your mouth, his fingers grasping your hair. He thrust once, twice and came, cocks pulsing with his release. You swallowed every single drop, and felt his hot load fill your belly.

“Damn, mate, you took all we had to give,” Thorne said affectionately, his cocks still nestled within you, plugging up the seed.

“Our mate is the strongest,” Ragnor said, kissing you passionately, his tongue tasting his seed in your mouth. “How are you feeling? The eggs?”

“I’m feeling… perfect,” you said with a soft smile. “The contractions are almost gone. When will the eggs come?”

Just in time, a knock echoed through the room. The doctor had returned and you would soon give birth to your eggs.

Any kind of support will make me smile so big! Feel free to share your thoughts and reblog! Next part will be the birth.

Quick Pro-Life Responses

Keep in mind: the fundamental disagreement between pro-life and pro-choice is on whether a fetus is being formed into a person, or if the fetus is already a person and is simply developing.

Confidently assert, “you say that because you think a fetus is not a person yet.”

They may concede fetuses are people in word, but still not conceptualize them as full people worthy of equal consideration.

“I have the right to bodily autonomy.”

Abortion is literally suffocation, poisoning, or dismemberment of a living human organism.

Abortion induces fetal demise by depriving a human of oxygen, blood, or vital function.

Bodily autonomy does not justify abuse of power and excessive force over a helpless person.

Abortion, a disproportionately brutal response to a passive threat, is aggressive violence.

“No one has the right to use my body.”

Correct. But, a prenatal person does not use a pregnant person’s body. They have no agency.

A pregnant person’s body takes care of the prenate. This care is ordinary and healthy.

Abortion is not like refusing care to a dying person, it is like murdering a healthy captive.

No one has the right to murder someone who they caused to be dependent on them.

“I have the right to revoke my consent.”

When you give consent, you agree to accept the foreseeable outcomes and risks of an action.

The creation of a bodily dependent is a foreseeable outcome of consensual intercourse.

You cannot revoke consent to outcomes. You can revoke consent to actions.

You may not violently sacrifice a helpless person to “mitigate” a risk of a consensual action.

“Anything dependent on my body is a parasite.”

If you make parasites, then you’re a parasite; it’s misogynist to suggest women are parasites.

The female body would not actively try to make pregnancy happen if it were parasitic.

Prenates never directly cause pregnant people harm; they are not aggressors or parasites.

Using developmental dependency to justify murder is simultaneously ageist and ableist.

“An embryo is just a clump of cells.”

Human embryos meet NASA’s criteria for the characteristics of distinct living organisms.

Human embryos are self-directed and their development follows a body plan.

Human embryos are organized and individual. They already have inherited capacities.

Tumors and gametes do not follow an organized body plan.

“Early humans have no cognitive capacities.”

By week 3, the embryo has a spine and is developing a nervous system.

By week 5, the embryo has a rudimentary brain that controls their pulse.

By week 8, the embryo has pain reflexes and can move their limbs.

It’s incredibly ableist to use the cognitive inabilities of a human being to justify their murder.

“If a fetus is a person, so is a brain-dead human.”

A brain-dead human is, obviously, dead. It’s an oxygenated corpse, the remains of a person.

Death occurs when human organisms stop resisting entropy and lose organic integration.

Preborn people actively resist entropy (decay) and have organic integration (unity).

An early human organism isn’t dependent on a mature brain to organize her vital functioning.

“Later abortions only happen for medical reasons.”

According to two studies by pro-abortion researcher at UCSF Katrina Kimport, this is untrue.

Kimport’s studies found that the reasons for later abortions are similar to early abortions.

Later abortions aren’t euthanasia; infants are stabbed with lethal injections and dismembered.

Perinatal hospice and palliative care relieve suffering. Dying babies deserve love, not murder.

“What about rape and incest?”

Abortion is not evidence-based treatment for sexual trauma. Abortion is traumatic as well.

A preborn child should not be condemned to the death penalty for their father’s crime.

It is safe for most menstruating children to carry pregnancies to viability with sufficient prenatal care.

Children conceived in incest are likely to have disabilities; that’s not reason to murder them.

“What about health of the mother?”

Every abortion ban in the US has exceptions for if the mother’s life or body is in grave danger.

We are not against tragic cases of triage. We are against elective induced abortion.

Some procedures coded medically as abortions aren’t legally or ethically defined as abortions.

Pro-life doctors report that the bans have not impeded their ability to treat their patients.

Your Core Arguments

There is no sound evidence or consistent logic that proves the preborn are the only class of human beings exceptional to the rule that humans are people with equal rights.

If a being is in the dynamic process of bonding with us as kin, then that being is a whole actual person by the manner of actively and inherently relating to our collective humanity.

Embryonic humans are full and equal people like us because they latently embody our same capacities and are manifesting them as we are, on account of sharing our nature.

Why Trump Is Partnering With Christian Nationalists

Donald Trump is portraying himself as a religious savior. He says Election Day will be: …”the most important day in the history of our country, and it’s going to be Christian Visibility Day.”

Trump has repeatedly compared his criminal trials to the crucifixion of Jesus, promoted videos calling his reelection “the most important moment in human history,” and that describe him as a divinely appointed ruler.

He claims to be a holy warrior against an imaginary attack on Christianity.

TRUMP: They want to tear down crosses//But no one will be touching the cross of Christ under the Trump administration. I swear to you.

He’s even selling his own version of the Bible.

Trump is playing to a rising white Christian Nationalist movement within the Republican Party.

Christian Nationalists believe that the law of the land is not the Constitution, but instead the law of God as they interpret it. Under this view, atheists and people of other faiths (including Christians of other denominations) are all second-class citizens.

Trump’s supporters are increasingly overt in their calls to replace democracy with a MAGA theocracy.

The idea that the will of voters is irrelevant because God has anointed Trump was a recurring message in the efforts to overturn the 2020 election.

In previous videos, I’ve highlighted how MAGA Republicans have embraced core elements of fascism. They reject democracy, stoke fear of immigrants and minorities, embrace a gender and ethnic hierarchy, and look to a strongman to lead and defend them.

The combination of fascism and Christian Nationalism is called Christofascism, a term first used half a century ago by the theologian Dorothee Sölle. Fascists rise to power by characterizing their opponents as subhuman. Christofascists take it a step further by casting opponents as not just subhuman, but actually demonic.

Framing opponents as enemies of God makes violence against them not only seem justifiable, but divinely sanctioned, and almost inevitable.

Christofascists want to strip away a wide range of rights Americans take for granted. Former Trump staffers involved in developing plans for a second Trump term have called for imposing “Biblical” tests on immigration, overturning marriage equality, and restricting contraception.  

And MAGA-aligned judges are already setting their dogma ahead of the Constitution. In his concurring opinion on the case that declared frozen embryos are people, Alabama Supreme Court Justice Tom Parker cited God more than forty times and quoted the Book of Genesis and other religious texts.

Nothing could be more un-American than the Christian Nationalist vision. So many of America’s founders came here as refugees seeking religious freedom. The framers of the Constitution were adamant that religion had no role in our government. The words “God,” “Jesus,” and “Christ,” don’t appear anywhere in the Constitution. And the very first words of the Bill of Rights are a promise that “Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof.”

Christofascism, or any religion-based form of government, is a rejection of everything America has aspired to be — a secular, multi-racial society whose inhabitants have come from everywhere, bound together by a faith in equal opportunity, democracy, and the rule of law.

Beware.

[prolifeproliberty]

Hey, I'm stumped on this objection, if it's alright, I want your input on this

"For these types of people I always give them a hypothetical situation for them answer So if you knew your wife was going to die by giving birth to the child would you let Your wife get an abortion or would you let your wife die in the child grow up without a mother?"

What do you think?

I would answer that the choice is never actually that simple. We imagine this cinematic moment where the doctor comes out to talk to the anxious husband in the waiting room and says “Sir, we can only save one of them. Should we save your wife or your child?” and he has to make that choice.

That makes a very dramatic movie scene, but it’s not real.

There are three categories of “life of the mother” situations:

1. Very early pregnancy. Mother has a life threatening condition and cannot be kept stable until the child reaches viability (now around 22 weeks with evidence-based best practices). Even in these situations, a direct abortion isn’t the life-saving care. Usually we’re talking about the mother needing a treatment for her life-threatening condition that risks the life of the baby. Most ethical choice is to treat the mother. If the baby dies as a result of the treatment, that is a tragic loss. If the baby doesn’t die, awesome! In this category, there is no way to save the baby without saving the mother, because if the mother died, the baby would too. Ectopic pregnancies fall in this category because there is currently no way to save the baby. If we developed the ability to get ectopic embryos to successfully re-implant in the uterus, that would become the ethical option.

2. Late-term complications. I’m going out of order here for a reason. This is anything where the mother’s life-threatening health issue starts after viability, but especially when we’re talking 30 weeks and on. Baby’s chance of survival with an early delivery goes up rapidly as baby approaches full term. In these cases, if the mother needs immediate treatment for a life threatening issue, she doesn’t actually need her baby to die. There is no reason to choose between the mother and child. A C-section is actually safer than a late-term abortion, since third trimester abortions usually still involve the mother laboring and delivering a dead baby. If the concern, as posed in the original hypothetical, is that she would “die by giving birth,” then she probably just needs a C-section (or a better doctor).

3. The third category is the most complex one. This is when the life threatening issue for the other begins when the child cannot yet survive outside the womb, but may be able to in a few weeks. This is where the difficult decisions are made. This category includes women diagnosed with cancer who might decide to delay treatment to protect their child until their child can be safely delivered. However, even here we can see examples of mothers who choose to receive treatment without first killing their child, and doctors who find innovative ways to treat life-threatening illnesses without harming preborn children.

The true answer is “save them both.” We can’t always - just as any doctor knows in a triage situation they can’t always save all the patients. The decision of who to save is never based on which patient is more human, more valuable, or more worth saving. The answer is instead based on how the doctor can save the greatest number of patients. If the doctor can save everyone, they do. If the doctor knows a course of action means for sure saving one patient, while another might not make it, but the alternative is losing both, then they will choose to save at least one. We almost never see a situation where the doctor has to arbitrarily choose between two patients - the decision is always based on the condition of each patient, the resources available, how much time there is, etc. There are algorithms for this kind of thing.

Basically I refuse to let unrealistic hypotheticals dictate actual policy on saving children.

Because people believe in the “we can only save one, choose!” scenario, we get doctors telling women that they will die if they don’t get an abortion, and then they cry to the media that they had to go to Colorado or California to get their “life-saving procedure.” The reality is that either the doctor could have treated the mother without first killing the baby and given the baby a chance to survive, or they could have delivered the baby and then treated the mother.

Anyone who says they couldn’t do the first option under ____ state abortion law is either lying or ignorant. If the mother’s condition is actually life-threatening, every state allows doctors to treat the mother. Killing a child doesn’t cure any illness.

Human Chimerism it’s a condition where a person possessed two sets of DNA rather than one, this prompt would focus on one type: “Vanishing-twin” otherwise known as “Fusion Chimerism” where one of the twin embryos was absorb by the stronger surviving twin embryo fused together into one. The person could live their lives without knowledge of it. Other than if there’s signs of strange birthmarks, different pigment on parts of there body and different eye color or a simple genetic tests could identify it.

A: Human I notice something, according to your medical data you have two-sets of DNA? Aren’t humans suppose to have one set? Is it mutation or genetic engineering or perhaps some weird organ transplant?

H: Oh no… I well before I was born, I sorta… ate my twin sibling embryo in the womb?

A: W-What?

H: I didn’t mean to, my brain wasn’t even develop yet. Anyway a part of them now lives inside me, as they’re too weak to gain a physical body.

A: So what does that mean for you, human, are you two people or one person?

H: I’m both, as weird as it sounds. I like the fact I’m my own twin and sorta carrying them a life they didn’t get the chance to see individually. This is just pushed more as I do want a younger sibling at some point before figuring out they’re within me this whole time.

A: I don’t know… but that’s just beautiful… (mind: As in a weird way to resolve for a human to avoid a potential identity crisis.)

On February 14th 2003 “Dolly”, the sheep, the first cloned mammal, was euthanized.

When scientists working at the Roslin Institute in Scotland produced Dolly, she was only lamb born from 277 attempts, from those rom 277 cell fusions, 29 early embryos developed and were implanted into 13 surrogate mothers. But only one pregnancy went to full term, and the 6.6 kg Finn Dorset lamb 6LLS, that’s Dolly to you and I, was born after 148 days. She was born on 5 thJuly 1996 but they never announced her birth for six months.

Dolly lived a pampered existence at the Roslin Institute, not far where I grew up. She mated and produced normal offspring in the normal way, showing that such cloned animals can reproduce.

Dolly the sheep was produced at Roslin as part of research into producing medicines in the milk of farm animals. Researchers have managed to transfer human genes that produce useful proteins into sheep and cows, so that they can produce, for instance, the blood clotting agent factor IX to treat haemophilia or alpha-1-antitrypsin to treat cystic fibrosis and other lung conditions.

This was a major news story around the world, Dolly even appeared on the cover of Time magazine, although I think they missed a trick and the headline should have been “Will There Ever Be Another Ewe”

Dolly was given a lethal dose of an anaesthetic she lives on though conserved by taxidermists her remains were conserved and she is on display in The National Museum of Scotland on Chambers Street, Edinburgh.

fuck it reposting my henren ivf essay

the fact that the ivf storyline follows so soon after henren's custody over denny was challenged (TWICE). karen doesnt just want another child, but specifically a biological one. and further, henren pursued an anonymous sperm donor rather than a friend/acquaintance. like they were trying to minimize threats (even illegitimate ones) to their custody as much as possible. im sure karen had many reasons beside that for wanting a biological child, but her proposal follows too soon after the custody challenges for that to not be on her mind in any capacity.

and eva, of course, is haunting this whole thing. it'd be understandable if karen harbored some jealousy over the fact that eva gave hen a baby ("all the people i love the most belonged to you first"). which then compounds karen's grief over the failed ivf: another way in which she cant measure up to eva. eva, who kept threatening karen's parenthood. here's something eva cant take away: my own flesh and blood. and she'd have been right in that logic, because biological parents ARE afforded more security in custody.

so of course karen wants a biological child, even though she can love a non-biological one all the same. she's been beat down by the heteronormative system. this IS the best option for her; it would give her a legal and mental security she hasn't yet had.

until she's beat by her own biology. a scientist, an expert on planets and stars and all that far-out stuff that exists beyond the bounds of human imagination, and she's defeated by the limits of her own body.

and then there's hen, who after three weeks of karen's mourning is frustrated. hen is self-professedly angry with her. she doesn't understand karen's grief; she tries to, but can't. karen herself doesn't even understand all the levels to her own depression. when karen emphasizes that the embryos weren't just an "idea" for her in the way it was for hen, she's not just talking about the physicality of it, but karen's faith in her own capacity for motherhood; an indisputable motherhood. one that eva can't touch, the courts can't touch, unknown fathers can't touch. no one could question her maternity, no one could take her baby away.

and the worst part is the's story's ending—or lack thereof. hen gets into that accident at work and karen drops her grief to take care of her. the ivf is forgotten. hen says "it's like that ivf stuff never even happened" and she's right. a crucial point of development for henren as wives, for karen as a character, is dropped unceremoniously, replaced by another tragedy where karen is relegated to the role of Supportive Wife.

Experimental evidence of dispersal of invasive cyprinid eggs inside migratory waterfowl

Ádám Lovas-Kiss, Orsolya Vincze, Viktor Löki, and Balázs András Lukács

Fish have somehow colonized isolated water bodies all over the world without human assistance. It has long been speculated that these colonization events are assisted by waterbirds, transporting fish eggs attached to their feet and feathers, yet empirical support for this is lacking. Recently, it was suggested that endozoochory (i.e., internal transport within the gut) might play a more important role, but only highly resistant diapause eggs of killifish have been found to survive passage through waterbird guts. Here, we performed a controlled feeding experiment, where developing eggs of two cosmopolitan, invasive cyprinids (common carp, Prussian carp) were fed to captive mallards. Live embryos of both species were retrieved from fresh feces and survived beyond hatching. Our study identifies an overlooked dispersal mechanism in fish, providing evidence for bird-mediated dispersal ability of soft-membraned eggs undergoing active development. Only 0.2% of ingested eggs survived gut passage, yet, given the abundance, diet, and movements of ducks in nature, our results have major implications for biodiversity conservation and invasion dynamics in freshwater ecosystems.

Writing Notes: Life Cycle

Erik Erikson’s 8 stages of the life cycle

Normative Crisis — Age — Major Characteristics

Trust vs. Mistrust — 0 to 1 — Primary social interaction with mothering caretaker; oral concerns; trust or mistrust in life-sustaining care, including feeding.

Autonomy vs. Shame and Doubt — 1 to 2 — Primary social interaction with parents; toilet training; beginnings of autonomous will.

Initiative vs. Guilt — 3 to 5 — Primary social interaction with nuclear family; beginnings of oedipal feelings; development of conscience to govern initiative.

Industry vs. Inferiority — 6 to puberty — Primary social interaction outside home among peers and teachers; school-age assessment of task ability.

Identity vs. Role Confusion — Adolescence — Primary social interaction with peers, culminating in heterosexual friendship; psychological moratorium from adult commitments; identity crisis; consolidation of resolutions of previous 4 stages into coherent sense of self.

Intimacy vs. Isolation — Early adulthood — Primary social interaction in intimate relationship (usually opposite sex); adult role commitments accepted, including commitment to another person.

Generativity vs. Stagnation — Middle adulthood — Primary social concern in establishing and guiding succeeding generation; productivity and creativity.

Ego Integrity vs. Despair — Late adulthood — Primary social concern is reflective: coming to terms with one’s place in the nearly complete life cycle, and with one’s relationships with others.

Erikson’s theory is called a psycho-self-reflexive, contextual process of finding and making meaning in the world.

It is not in conflict with scientific knowledge because, on the hermeneutic account, all psychological knowledge is concerned with this sort of understanding of our world (Verstehen), and not about explaining the universal laws of nature.

His theory charted changes in personality over the entire life cycle, rather than focusing on the early childhood years as critical to all later personality functioning.

Erikson proposed 8 stages of human development, each with its own normative crisis, by which he meant not a debilitating conflict, but rather a period of heightened vulnerability and potential.

He viewed human development as occurring in orderly stages, each with its own special characteristics and its own particular age relationship.

The stages always occur in a particular order and cannot be skipped.

His stages illustrate what Erikson termed the epigenetic principle.

Briefly stated, this principle proposes that critical elements of human personality have a ground plan from which they grow, similar to the physical growth principle by which the undifferentiated cells of embryos develop in orderly ways into organ systems. Thus, all human beings will face the normative crisis of trust versus mistrust in the period of infancy.

The resolution of this crisis leaves the infant with an abiding sense of either trust or mistrust that will become part of later personality functioning.

Each stage builds upon what has gone before and carries elements of itself into future stages.

Erikson’s contributions to psychology, particularly to the study of personality, can be divided into 4 major areas:

His emphasis on the importance of the entire life cycle in personality change

The psychosocial origins of personality

The centrality of self-identity in personality development

The importance of life histories for personality study

Is it possible for Danny to have a female clone as a male?

Short answer: Kinda. There are multiple options.

I'm not an expert by no means, but I'll try to simplify cloning for you. Also, reproductive cloning of humans is more of theoretical field than anything.

Let's start of with this: Dani probably isn't exactly a clone. A cloned embryo is essentially an identical twin of the original organism. She isn't that, because she isn't the same sex. Even if clones are genetically identical with one another, they will not be identical in physical or behavioral characteristics, because DNA is not the only determinant of these characteristics. That's why she is shorter, not as thin, behaves differently etc. Dani was made by reproductive cloning - the process of cloning an entire organism.

So, how to make Dani out of Danny?

To create a female clone from a man you could take his cells and turn off the Androgen receptor genes. The person will develop as female with XY chromosomes and will have Androgen Insensitivity Syndrome. This method creates genotypically male individual but phenotypically female, making them intersex. This would make a clone, but it wouldn't be "genetically" female.

Deleting the Y chromosome. This will create a female child with Turner's Syndrome. Most of the effects of which can be countered with hormone supplements at appropriate development stages.

Duplicate the male X chromosome - turning an XY into an XX. Though the resulting individual wouldn't be a perfect clone because the proportions of source DNA wouldn't be right, all the source material would come from the original male.

Bring in donor chromosomes from an unrelated female. All other genes will be identical to the "parent's" genome, and by controlling which X is active (only single X is active in a female). The 'clone' wouldn't be as identical as the other methods.

So yeah, either Danny is trans or Dani is intersex :D

Easily my most popular post was about paddlefish, so this Wet Beast Wednesday it's time to give them their moment in the sun. Paddlefish are members of the family Polyodontidae and one of only two surviving members of the order Acipenseriformes, the other being sturgeons. The Acipenseriformes are one of the oldest lineages of ray-finned fish and diverged from the ancestors of all other modern ray-finned fish around 300 millions years ago. While paddlefish have been around since the Cretaceous period, there is only one living species, the American paddlefish (Polyodon spathula). Another modern species is the Chinese paddlefish (Psephurus gladius), but the last sighting of one was in 2003 and they were officially declared extinct in 2022. In this post, unless I specify otherwise everything I say will be referring to the American paddlefish.

(image: either an American paddlefish or a basking shark that got its nose caught in a hydraulic press)

Paddlefish are named for their very long rostrums which are packed full of electrorecepting organs called the ampullae of Lorenzini used to sense electric fiends in the water. The ampullae are not only on the rostrum, but also on the head and large skin flaps that extend from the operculum (gill cover). They are so sensitive that paddlefish are able to sense the movement of individual body parts of zooplankton. Paddlefish use their rostrums to detect their prey, which consists almost entirely of zooplankton. They are ream suspension feeders, swimming toward swarms of zooplankton with their mouths open. As the water passes through the gills, gill rakers filter out the zooplankton, which is then swallowed. Other fish that use this feeding method include basking sharks. While the rostrum is the primary method of prey detection, other ampullae on the head and operculum flap allow the fish to still effectively find food even if the rostrum is damaged or destroyed. When working fish fish on the Mississippi I caught multiple paddlefish who lost their rostrums to propeller strikes and were still doing fine. Electroreception is their main sense, with their eyesight being extremely poor.

(image: the skeletal structure of the rostrum)

As chordates, paddlefish have a notochord that runs from the head down the body. In most modern chordates, the notochord is only present in the embryo and is lost during development. This is not the case for paddlefish, who retain their notochord into adulthood, where is acts as a soft spine. While paddlefish (and their sturgeon cousins) are bony fish, they have lost most of the bone and now have skeletons composed almost entirely of cartilage. It is for this reason that early taxonomists initially miscategorized paddlefish as freshwater sharks. To be fair, they do look a lot like miniature basking sharks. Who crossbred with spoons. They also lost their scales and have smooth, easily damaged skin instead. Their skin is so easily damaged that just being caught in nets can leave scars. Paddlefish are large and long-lived. The American species reaches an average of 1.5 m (5 ft) in length, with the rostrum making up a third of that, and a weight of 27 kg (60 lbs). The largest recorded specimen was 2.16 m (7 ft 1 in) and an estimated 90 kg (198 lbs). Despite being one of the largest American freshwater fish, they paled in comparison to the Chinese species, which could reach 3 m (9.8 ft) and 500 kg (1,100 lbs). The largest Chinese paddlefish on record was 7 m (23 ft) long and was estimated to weigh "a few thousand pounds". The Chinese paddlefish also preferred larger prey, feeding largely on small fish and crustaceans. American paddlefish live an average of 5 to 8 years, but in the right circumstances can live up to 60 years, with females generally living longer. The Chinese paddlefish had an estimated average lifespan of 29-38 years. In both species, it is believed that human activity drastically reduced their average lifespans.

Paddlefish travel upriver to spawn in spring. They prefer to span on shallow gravel bars that would be exposed to air if not for spring rainfall and snow melt. Because they require very specific conditions to spawn, spawning rarely occurs every year. Every 4-5 years is more common. Paddlefish are broadcast spawners, with both males and females releasing gametes into the water column. Fertilized eggs are negatively buoyant and sticky. They will sink to the bottom and stick to the gravel. Once hatched, larvae will be swept down river to develop in deep pools. They are born without rostrums, which start to grow almost immediately. Paddlefish mature late, with females becoming sexually mature between 7 and 10 years of age, with a few not maturing until as late as 16-18 years. Human activity is resulting in many individuals dying before becoming sexually mature. American paddlefish are cross-fertile with the Russian sturgeon (Acipenser gueldenstaedtii), producing a hybrid offspring known as the sturddlefish despite being separated by the Atlantic ocean and 184 million years of evolution. This was discovered by accident when scientists introduced paddlefish sperm too sturgeon eggs as a control group for an experiment. I made a post on the sturddlefish which you can read here.

(image: three larval paddlefish of different ages)

American paddlefish are classified as vulnerable by the IUCN. They are native to the Mississippi river basin that encompasses much of the midwest and south of the United States, but their range used to be larger, reaching into Lake Huron, the Northeastern U.S. and parts of Canada. This reduction of native range is due largely to human activity, mostly overfishing and habitat loss. Zebra mussels, an invasive species, are a major competition for paddlefish as theybith feed on zooplankton. Reintroduction programs have begun in some of the states they were extirpated from, and they have been introduced to China, Cuba, and multiple countries in Europe for use in fishing and caviar production. 13 states allow for sport fishing of paddlefish, some of them relying on restocking to maintain a population for anglers. Paddlefish meat is edible and their eggs can be used for caviar. Paddlefish can be raised in captivity, but must will not spawn in captivity and so establishing captive populations requires gonad extraction and artificial insemination. Poaching of wild paddlefish for their eggs is an ongoing problem. The extinction of the Chinese paddlefish is believed to be the result of overexploitation and habitat loss.

Women's rights/feminism isn't meant to be a catch-all for other human rights movements as many women have pointed out.

I think there's one exception to this.

I genuinely think that children's rights and protections are and should be folded into women's rights. They're a vulnerable population due to their neurological development. And I think due to the connection of youth to women and women's rights (such as issues of pregnancy, childbirth, etc.), it makes sense for children's rights and protections to be spearheaded by women. I am coming from this perspective as a childfree, homosexual woman.

There are some instances in which it's appropriate to incorporate the thoughts and experiences of particularly older youth, but the children's rights/the youth movement overwhelmingly isn't able to lead itself, nor do I think children/youth should carry the burden of ensuring their own rights and protections. They aren't adults. We shouldn't expect them to be adults. It's a unique component to youth as a vulnerable and heavily abused population. Youth inherently biologically lack executive functioning (planning, impulse control, rational thinking, etc.) - even only half of this development occurs by age 18.

I think children's rights and protections should be under the wing of women's rights, and the wellbeing of children and youth should be also centered and considered when considering issues pertaining to the adoption and foster care system, surrogacy, and sperm donation. How are these systems affecting women, and also, how are they going to impact the child and their wellbeing?

And, since this is Tumblr, I think this needs to come from a pro-choice perspective. There's a biological difference between an infant or child that's already born versus a developing embryo or fetus that shouldn't be prioritized over the rights and wellbeing of women, or used as point of government and male control over women.

Currently there are so many political groups that want access to children and teenagers, and even young adults. They're so able to be groomed, and grooming someone young can mean influencing future culture and creating a form of exploitation that's difficult to free themselves from due to grooming and political influences being so embedded by a young age, into the psychology of a person's core experiences.

Vascular cells comprise the circulatory system and include the cardiovascular system, or vascular system, that consists of the heart and blood vessels (from Greek kardia meaning heart, and from Latin vascula meaning vessels). The network of blood vessels are the great vessels of the heart including large elastic arteries, and large veins; other arteries, smaller arterioles, capillaries that join with venules (small veins), and other veins. The circulatory system is closed in vertebrates, which means that the blood never leaves the network of blood vessels.

Sonic hedgehog protein (SHH) is encoded for by the SHH gene. The protein is named after the video game character Sonic the Hedgehog. This signaling molecule is key in regulating embryonic morphogenesis in all animals. SHH controls organogenesis and the organization of the central nervous system, limbs, digits and many other parts of the body. Sonic hedgehog is a morphogen that patterns the developing embryo using a concentration gradient characterized by the French flag model.[6] This model has a non-uniform distribution of SHH molecules which governs different cell fates according to concentration.
