This article talks about how undifferentiated cells are developing into more than the 200 types of cells the adult human body holds. Scientists say that one day stem cells may be used to replace or repair damaged cells, and can also have the potential to drastically change the treatment of conditions like cancer, Alheimer's and Parkinson's disease and even paralysis. Most research has been conducted on embryonic stem cells lines -- cultures of cells derived from four or five day old embryos, or fertilized cells. People that are against the use of embryos in stem cell research, which often uses embryos dicarded by fertility clinics, want it to be severely restricted or banned outright as inhumane.

i think soceling on the interent is not a bad thing but when the students start bring violence or seriouse stuff into it then it doesn't make it fun for everyone els. and they should have to pay the conciquences
I read this study too and I am glad of the fact that there are no demonstrable ill effects. I am concerned about the one line: peers trust peers and learn from them more than from an adult. I think it was probably the same in my day too, but my concern now is that it is so much easier to tune out adults. As the article mentioned, kids wake up, login to Facebook or MySpace, text, talk, etc. They seem to have created their own world. So my concern is that when they should be learning at school, they are texting, as the article says. I am concerned about this for obvious reasons. Students have always had atough time focusing, getting work down, paying attention, etc. Now they have far more opportunities to get distracted.
I would never do something like that to my unborn child i don't beleive in it but i do beleive in finding a cure for the future cancer victums, i think the decision should be left of to the parent of the baby, but i don't think women should have babies just to do this to them
