cancer treatment in 2025:
find the tumor, cut it out, poison the rest with chemo, hope the patient survives
cancer treatment in 2026:
sequence the tumor's DNA, identify the exact mutations driving it, design a treatment built around those mutations specifically, train the patient's own immune system to hunt them down
it's coming fast, bio/acc.
something funny that happens is that after a long day when babies are finally in bed and everything is finally quiet, you and your spouse will want to go look at the photos of the babies you took together
Sleep deprivation and constant fear of bad things happening. It makes the sleep deprivation worse when you’re almost finally asleep and you realize you haven’t stared at your baby’s chest rising and falling in like 30 minutes
By the end of a pregnancy a woman is carrying up to 50 percent more blood than she started with.
Her body has to build all of it, out of nothing, on a schedule.
The heart starts changing at five weeks, before most women have told anyone. Heart rate climbs 15 to 30 percent. The volume pushed with each beat rises 15 to 25 percent. Total output goes up by somewhere between 20 and 50 percent, and by the end all four chambers of her heart have enlarged.
The muscle mass of the left ventricle increases by as much as half. Athletes get similar changes from years of endurance training. She does it in nine months without leaving the sofa, and the researchers who study it have remarked on the resemblance.
The plumbing gets rebuilt to match. The vessels feeding the womb carry less than one percent of her blood flow before pregnancy and up to a quarter of it by the end. Blood flow to the kidneys rises by half. Her vessels relax so that all this extra volume can move without her blood pressure climbing.
During labour it goes further. Output rises another 15 percent in the first stage and 50 in the second. Each contraction squeezes 300 to 500 millilitres of blood back into her circulation.
Then the whole thing is dismantled. Within an hour of delivery her output starts falling back. Most of it has reversed within weeks, and the structural changes to the heart itself take about six months to undo.
She grew an extra organ's worth of circulation, ran it for nine months, and then took it apart, and nobody mentioned it at any appointment.

Guys I have a theory, I think Patrick didn’t do it and Lindsay actually did it and that would explain why she’s on trial for the brutal murder of her children.
Researchers at Fred Hutchinson examined the brains of 59 women after death. In 63 percent of them they found male DNA, almost certainly left behind by a son. The oldest of those women was 94, and the cells were still sitting there.
Around week four or five of pregnancy, before most women have told anyone, a handful of the baby's cells cross into the mother's bloodstream. Some of them never leave. Scientists call it microchimerism, meaning you are carrying a few of another person's cells inside you. Doctors at Leiden University in the Netherlands checked organs from women who had recently been pregnant and found the baby's cells in every single one. Liver, lungs, thyroid, kidneys, bone marrow, skin, heart.
They do not sit idle. When researchers in Ireland biopsied cesarean scars from 70 women, they found the baby's cells living in the skin as ordinary skin cells, making collagen and repair proteins right at the cut. The child helped close the wound its own birth made.
At Mount Sinai, scientists tagged fetal cells with a glowing marker in pregnant mice, then damaged the mothers' hearts. The fetal cells went to the injury. They became heart muscle and the lining of blood vessels. Nobody has proven the human version yet, but doctors have noticed for years that women who develop heart failure around childbirth recover better than almost any other kind of heart failure patient.
In a study of 177 women, fetal cells appeared in the blood of 85 percent of the healthy participants and only 64 percent of the women who had a very early, non-invasive breast cancer. Nobody has worked out yet whether the cells are doing the protecting. The same cells also turn up in Hashimoto's, an immune condition that attacks the thyroid, so this is a gift with complications.
A French team looked at umbilical cord blood in 2021 and found cells belonging to the baby's grandmother in 5 of 28 samples. Cells that crossed one placenta decades earlier had crossed a second one. Three generations of women, alive in a single bloodstream.
Which means the pull a mother feels toward her child has a physical form. It sits in her liver, her heart, and often her brain, and it stays there for the rest of her life.
