The madness of science: D 71 D'OH
Oh the irony.
Science is the ethical problem as the woman is at tatuaggetto.
"All of a sudden you do not like most ', what do you do? You take it, you can not ... going to do another more 'big! ": D
Section article" undifferentiated ethics "- Scientific American August 2010
" When Researchers first demonstrated in 2007
That Could Be human skin cells reprogrammed to behave like stem cells can fully differentiate into
That other cells, Politicians and scientists alike rejoiced
. All the potential of embryonic stem cells might be
Harnessed with the new techniques without the political and
moral controversy associated with destroying a fertilized egg.
That optimism, however, may be misplaced; these transformed
cells, known as induced pluripotent stem cells (iPS cells), actually
present equally troubling ethical quandaries...
Not only do many of the ethical challenges posed by embryonic stem cells
remain, but the relative ease and low cost of iPS techniques,
combined with the accessibility of cells, accelerate the need to address
futuristic-sounding possibilities such as creating gametes for reproduction...
Scientists have already reported progress in growing precursor cells
for eggs and sperm from both iPS and embryonic stem cell lines...
Sperm and egg from skin cells eventually might be used for reproductive
purposes, enabling parenthood at ANY AGE using tissue from either the
living or DEAD...
PS cells could enable prospective parents to choose embryos for desired
traits more easily than they can with conventional assisted-reproduction
technologies...
Although Kazuo Kato, a bioethicist at Kyoto University in Japan,
called human reproductive cloning directly from iPS cell lines
“very hypothetical,” he pointed out progress for that possibility
when he noted that three teams had produced mouse clones from iPS cells.
Less expensive and more efficient than the process that produced Dolly the sheep,
the iPS approach also would skirt the language of many current prohibitions
against human reproductive cloning...
... how will a disillusioned cell donor withdraw when iPS cell lines have been
distributed all over the world? Bedrock International Research
norms of consent and withdrawal May No Longer be workable ...
"Biobanks" all over the world Already store biological material and related data
for research, and many do not seek consent for future work
as long as the material can not be connected back to the donor. " ;
Oh my: D
