Just over one decade after successfully cloning Dolly the sheep, scientists have cloned the first human embryo from adult cells. The breakthrough could pave the way to personalized organ transplants and therapies based on stem cells that could theoretically be grown into any type of human tissue.
The world’s first cloned human embryo was created last year when a team of scientists used cells from a fetus and an eight-month-old infant. The new experiment, results of which were published in the journal , involved making a clone embryo from cells taken from adult men, ages 35 and 75. The procedure was done by sucking out the nucleus out of an adult cell and placing it in a donor egg without a nucleus.
Currently, stem cells can only be extracted from embryos leftover from in vitro fertilization. The discovery could be used for future organ transplants but it’s still far from leading to human cloning. Instead, the new cell cloning technology could be the basis of growing personalized stem cells. Although exciting, the new breakthrough revisits the moral implications and ethical dilemmas related to cloning.

The conclusions of this article are flawed. Currently the process is fertilizing an existing embryo with an adult cell to create a clone. The only way that could result in personalized organ transplants, is if we "grew" a symbiote human to maturity then stole it's organs! The ramifications of that process are unthinkable. Furthermore, the scientific process for this research itself is highly immoral. Creating fertilized human embryos just to study them and kill them in the name of "science" is something right out of the books of Nazi Germany in the 1940's. How dare we? If NASA found anything even closely resembling a human embryo, especially a fertilized human embryo on Mars we would all be jumping up and down saying: Human life was found on Mars. Human life is held to a higher standard, which is why we have laws against murder; but not against say, killing cows for food. Our grand children will look back on these times in disgust.
