On this day in 1364, Pope Urban V signed off on what would become Jagiellonian University.
UJ is one of the oldest universities in Europe, older than most of Oxford's colleges, and still teaches students today.
Copernicus studied there. So did two future popes🎓

His Majesty King Harald V of Norway has died; His Majesty King Haakon VIII has succeeded him. The King is dead; long live the King! May God grant him and his people many happy years.
If my freedom of religion doesn’t allow me to avoid injecting aborted baby tissue into my child, then I have no freedom of religion. The MMR vaccine is an abomination!
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.

"If we do not return to the old ways, if education is not restored to the hands of the church, and if science is not everywhere placed in the second rank, the evils that await us will be incalculable: we shall become brutalized by science."
