Antinomy discovered 44 months ago
From the page: "In the end they discovered that Jane is a chimera, a mixture of two individuals - non-identical twin sisters - who fused in the womb and grew into a single body. Some parts of her are derived from one twin, others from the other. It seems bizarre that this can happen at all, but Jane's is not an isolated case."

"Human chimeras were once thought to be so rare as to be just a curiosity." In Minnesota, pigs are being born with human blood in their veins. In Nevada, there are sheep whose livers and hearts are largely human. In California, mice peer from their cages with human brain cells firing inside . . . http://www.msnbc.msn.com/id/6534243/ Cats provide a unique opportunity to observe X chromosome inactivation and help visualize how it affects all females. Tortiseshell cats have a coat that is a mixture of black and orange hair. If research on human embryonic stem cells ever gets going, people will be hearing a lot more about chimeras, creatures composed of more than one kind of cell. The world of chimeras holds weirdnesses that may require some getting used to. http://ucsystembiotech.ucdavis.edu/IST/snt1229542005515.asp.htm

From the page: "Human chimeras were once thought to be so rare as to be just a curiosity. But there's a little bit of someone else in all of us, says Claire Ainsworth, and sometimes much more..." READ THIS!

From the page: "EXPLAIN this. You are a doctor and one of your patients, a 52-year- old woman, comes to see you, very upset. Tests have revealed something unbelievable about two of her three grown-up sons. Although she conceived them naturally with her husband, who is definitely their father, the tests say she isn't their biological mother. Somehow she has given birth to somebody else's children." She's a whore, a whore I tell you! No, seriously, she isn't. Well...she may be for all I know but thats not the point is it. I mean for all I know she may go out and get banged by 3, 4, 5 blokes at a time. I'm not here to judge. I'd love to be, but i'm not. Enough nonsense. A very interesting read from one of the finest publications around. New Scientist. Long article, so only click if you're in the mood.

what a strange and fascinating article. From the page: "Jane is a chimera, a mixture of two individuals - non-identical twin sisters - who fused in the womb and grew into a single body. Some parts of her are derived from one twin, others from the other."

From the page: "Yet this kind of chimerism may still be common enough to cast doubt on the way we carry out genetic tests of parenthood. Kruskall is currently helping out with a court case where a woman is suing her partner, claiming that he is the father of her child. In a bizarre twist that would nonplus even Jerry Springer, tissue-typing tests proved he was the father, but ruled her out as the mother. The situation could be explained by chimerism in the mother, Kruskall speculates."

absolutely fascinating read...thanks to Arjuju for the stumble From the page: "Human chimeras were once thought to be so rare as to be just a curiosity. But there's a little bit of someone else in all of us, says Claire Ainsworth, and sometimes much more..."

Fast-In-ATING!!!! From the page: "During pregnancy, the blood of the mother and fetus are kept separate, but some cells manage to slip through, meaning that you will have picked up some cells from your mother, and she some from you. In fact, some 80 to 90 per cent of women carry their children's cells or DNA in their blood during pregnancy and up to 50 per= centcarry them for decades after giving birth, a condition called microchimerism (New Scientist, 24 April 1999, p 4)."

More blows than were expected: from the page: "On one level, you are you, a person with your own thoughts and feelings. But zoom in one level and you are a supercolony of individual cells, some cooperating, others competing. Zoom in to the level of your genome, and you find individual chromosomes and genes, all jostling to get through to the next round of natural selection."
