Comment How many imperfect clones were euthanized? (Score 1) 261

This is the most important reason why cloning of humans is completely unacceptable.

"cloning mammals by nuclear transfer is still highly inefficient, with Dolly the only lamb that survived to adulthood from 277 attempts"(http://en.wikipedia.org/wiki/Dolly_(sheep))

Is the company that does the cloning being open about this aspect of the procedure? If they are trying to pretend that they can evaluate the embryos created by nuclear transfer and only bring the least damaged ones to term, they are making a preposterous claim. The problem of evaluating a DNA sequence for all possible DNA damage is fantastically complicated, probably formally undecidable in the Alan Turning's terminology.

How many copies of these treasured pets are living a few pain-racked days in a laboratory?

A Stark Warning On Climate Change 926

cliffski writes "In a report based on computer predictions, UK government advisor Professor David King said that an increase of even three degrees Celsius would cause drought and famine and threaten millions of lives The US refuses to cut emissions and those of India and China are rising. A government report based on computer modeling projects a 3C rise would cause a drop worldwide of between 20 and 400 million tonnes in cereal crops, about 400 million more people at risk of hunger and between 1.2bn and 3bn more people at risk of water stress."
