EMAIL FROM LEE PENN

Check this out:

washingtonpost.com: Of Mice, Men and In-Between

Read the whole story, carefully. This is the fruit of our "advanced" society. It's beyond Brave New World.

After reading this story, re-read C.S. Lewis' Hideous Strength ... and reflect that we all live in Belbury now, and the N. I. C. E. are in charge. And re-read the Lord of the Rings, and recall who was interbreeding Orcs and Men. To see the meaning of this in non-fiction terms, re-read C. S. Lewis' Abolition of Man,

In his last published essay, "We Have No 'Right to Happiness'," C. S. Lewis concluded:

"Though the 'right to happiness' is chiefly claimed for the sexual impulse, it seems to me impossible that the matter should stay there. The fatal principle, once allowed in that department, must sooner or later seep through our whole lives. We thus advance toward a state of society in which not only each man but every impulse in man claims carte blanche. And then, though our technological skill may help us survive a little longer, our civilization will have died at heart and will - one dare not even add the word 'unfortunately' -- be swept away."

He wrote this in 1963. and this prophecy is being fulfilled in our hearing.

Kyrie eleison.

Scientists Debate Blending Of Human, Animal Forms

In Minnesota, pigs are being born with human blood in their veins.

In Nevada, there are sheep whose livers and hearts are largely human.

In California, mice peer from their cages with human brain cells firing inside their skulls.

These are not outcasts from "The Island of Dr. Moreau," the 1896 novel by H.G. Wells in which a rogue doctor develops creatures that are part animal and part human. They are real creations of real scientists, stretching the boundaries of stem cell research.

Biologists call these hybrid animals chimeras, after the mythical Greek creature with a lion's head, a goat's body and a serpent's tail. They are the products of experiments in which human stem cells were added to developing animal fetuses.

Chimeras are allowing scientists to watch, for the first time, how nascent human cells and organs mature and interact -- not in the cold isolation of laboratory dishes but inside the bodies of living creatures. Some are already revealing deep secrets of human biology and pointing the way toward new medical treatments.

But with no federal guidelines in place, an awkward question hovers above the work: How human must a chimera be before more stringent research rules should kick in?

The National Academy of Sciences, which advises the federal government, has been studying the issue and hopes to make recommendations by February. Yet the range of opinions it has received so far suggests that reaching consensus may be difficult.

During one recent meeting, scientists disagreed on such basic issues as whether it would be unethical for a human embryo to begin its development in an animal's womb, and whether a mouse would be better or worse off with a brain made of human neurons.

"This is an area where we really need to come to a reasonable consensus," said James Battey, chairman of the National Institutes of Health's Stem Cell Task Force. "We need to establish some kind of guidelines as to what the scientific community ought to do and ought not to do."

Beyond Twins and Moms

Chimeras (ki-MER-ahs) -- meaning mixtures of two or more individuals in a single body -- are not inherently unnatural. Most twins carry at least a few cells from the sibling with whom they shared a womb, and most mothers carry in their blood at least a few cells from each child they have born.

Recipients of organ transplants are also chimeras, as are the many people whose defective heart valves have been replaced with those from pigs or cows. And scientists for years have added human genes to bacteria and even to farm animals -- feats of genetic engineering that allow those critters to make human proteins such as insulin for use as medicines.

"Chimeras are not as strange and alien as at first blush they seem," said Henry Greely, a law professor and ethicist at Stanford University who has reviewed proposals to create human-mouse chimeras there.

But chimerism becomes a more sensitive topic when it involves growing entire human organs inside animals. And it becomes especially sensitive when it deals in brain cells, the building blocks of the organ credited with making humans human.

In experiments like those, Greely told the academy last month, "there is a nontrivial risk of conferring some significant aspects of humanity" on the animal.
