Two teams of scientists reported yesterday that they had turned human skin cells into what appear to be embryonic stem cells without having to make or destroy an embryo — a feat that could quell the ethical debate troubling the field.Source
All they had to do, the scientists said, was add four genes. The genes reprogrammed the chromosomes of the skin cells, making the cells into blank slates that should be able to turn into any of the 220 cell types of the human body, be it heart, brain, blood or bone. Until now, the only way to get such human universal cells was to pluck them from a human embryo several days after fertilization, destroying the embryo in the process...
The new method sidesteps other ethical quandaries, creating stem cells that genetically match the donor without having to resort to cloning or the requisite donation of women’s eggs. Genetically matched cells would not be rejected by the immune system if used as replacement tissues for patients. Even more important, scientists say, is that genetically matched cells from patients would enable them to study complex diseases, like Alzheimer’s, in the laboratory.

I finally got a chance to watch A Scanner Darkly, and wasn't disappointed. I started watching it for the art, because that's what everyone hyped up. It's animated, but based on live action. I watched for the art, but stayed for the plot. I must have missed that it was based on a novel by Philip K. Dick or I would have seen it sooner, definitely.Whatever it is that's watching, it's not human, unlike little dark eyed Donna. It doesn't ever blink. What does a scanner see? Into the head? Down into the heart? Does it see into me, into us? Clearly or darkly? I hope it sees clearly, because I can't any longer see into myself. I see only murk. I hope for everyone's sake the scanners do better. Because if the scanner sees only darkly, the way I do, then I'm cursed and cursed again. I'll only wind up dead this way, knowing very little, and getting that little fragment wrong too.Good stuff. Go rent it.

Wikipedia is a mainstream encyclopedia, wrapped up in and documenting popular culture. It also has the unique characteristic of being an encyclopedia that anyone can edit, which means that it is edited by the masses who draw on their experiences of living in popular culture.It really is fascinating, a system designed to chronicle pop culture, built on counterculture concepts. What a mashup! I am still, totally, a fan of the site. You won't be hearing any rant coming from me.
I'm personally fascinated by the dynamic between the established popular culture, and counterculture movements. MediaWiki itself is an experiment in countering the culture of traditional publishing. Though I was born decades later, I enjoy reading histories of the counterculture movements in the United States during the 1960s.
