Male DNA Found In Female Brains
Discovery suggests fetal cells can slip through blood-brain barrier

Children live on in their mothers’ brains for decades, and not just as memories. Scientists have found pockets of male DNA, presumably from boy fetuses, in the brain tissue of women who died in their 70s.
Not only is male DNA present in women’s brains, it’s common, researchers report online September 26 in PLOS ONE. J. Lee Nelson of the Fred Hutchinson Cancer Research Center in Seattle and her colleagues found snippets of a male-only gene in the brains of 18 of 26 women who died without neurological disease. The male DNA was spread throughout their brains.
The technique used in the study couldn’t distinguish if the DNA was from intact, functional brain cells, though in a separate test of brain tissue from a different woman, Nelson and colleagues did spot nuclei from male cells in the brain. Earlier studies in mice hinted that these foreign cells can integrate themselves into the brain and start functioning as nerve cells.
So far, cells from fetuses have turned up in women’s blood, livers, lungs, heart and other organs, so finding male DNA in the brain isn’t a complete shock, says geneticist Kirby Johnson of Tufts University in Medford, Mass., who wasn’t involved in the study. “From everything we knew, it’s not really that surprising.”What’s interesting is how the DNA could have gotten there. Male cells from a fetus could have broken through the blood-brain barrier — a wall that protects the fragile brain from pathogens in the blood. But that shouldn’t be possible, Johnson says.

Doesn’t surprise me, it’s not like the barrier is perfect. It’s just tissue...
Just what we need to hear on this site.
Well that's no surprise, that's all they ever think about is how to get themselves some of that male DNA.
I know how it got there!
LLS
The jokes on this thread should just write themselves but my wife is seated next to me and I won’t touch this with a ten foot pole.
Something about women with male DNA influenced brains being able to drive skillfully & vote based upon facts and logic would make a great OWWWWWWW! Stop hitting me dear!!!
One of my ex-GF’s in college threw a laptop at my head with a single swing when we broke up. I was 20 feet away and just grazed me. Yeah, there might be some truth to it.
If that were true, they could drive and wouldn’t argue with men about things that are obvious.
Forgot to mention that they could also instantly tell upon entering a bathroom whether the toilet seat is up or down and adjust it accordingly, rather than screaming and bitching about it.
Don’t tell Sandra Fluke.
I’ll just bet there’s another way to get male dna into the female brain but I won’t mention it here because I would probably get the boot.
Ok, Let the double entendres begin!
We need an outlet, like the Indians had, let the women express their feelings by butchering the Prisoners.
Yeah, and in Monica Lewinsky’s case all over her clothing.
Unfortunately not ENOUGH male DNA as these dumb-ass females vote for Obama!
Me either, OMG I can't quit laughing...
