A facinating study may explain why people love to argue on this forum. Even though a mere argument falls short of physical violence, still there is an aggressive quality to it.

[Yes, this is about as close to physical violence one can do on a forum. or

But IMHO, there is a great deal of emotional violence that goes on here on this forum.

The scientific cloning community looked on skeptically this week when a private research company announced that it had cloned the first human embryos. Researchers at Stemagen, based in La Jolla, Calif., reported in the journal Stem Cells, that they had produced three cloned blastocysts (early-stage embryos) from 25 donated egg cells by the procedure of somatic cell nuclear transfer, which involves replacing an egg nucleus with that of an adult donor's skin cell. (In this case, one donor was the company's CEO, Samuel Wood.) Although Stemagen said the cloned embryos grew to the stage that yields embryonic stem cell lines—the company's stated goal is to created cloned cell lines for therapeutic purposes—other experts in the field told news outlets that the blastocysts in published photographs didn't look that healthy.
