TEXTO:

    For the first time, scientists have created human

embryos that are genetic copies of living people and used

them to make stem cells — a feat that paves the way for

treating a range of diseases with personalized body

5 tissues but also ignites fears of human cloning. If

replicated in other labs, the methods detailed Wednesday

in the journal Cell would allow researchers to fashion

human embryonic stem cells that are custom-made for

patients with Alzheimer’s disease, diabetes and other

10 health problems.

    Theoretically capable of reproducing themselves

indefinitely, these stem cells could be used to grow

replacements for a wide variety of diseased cells — those

of the blood, skin, heart, brain, muscles, nerves and

15 more — that would not risk rejection by the patient’s

immune system.

    The report also raises the specter that, with a

high-quality donor egg, a bit of skin, some careful tending

in a lab and the womb of a willing surrogate, humans

20 have cracked the biological secret to reproducing

themselves. That is an objective American scientists

have squarely renounced as unethical and scientifically

irresponsible. At the same time, most acknowledge that

such “reproductive cloning” will one day prove too

25 tempting to resist.

    In the hope that other researchers will validate and

extend their results, the scientists at Oregon Health &

Science University provided an exceptionally detailed

account of their techniques. For anyone with a

30 well-equipped fertility lab, the comprehensive guide could

also be a useful handbook for cloning a baby. The

success of the experiments rekindled debate among

bioethicists, who have long anticipated that human

cloning would become a reality.

Dogged determination

    Sometimes scientists seem to be telling us what

we already know. Thus a recent study at Britain’s

University of Portsmouth determined that if you told a

dog not to take a piece of meat, then turned out the light

[5] so he thought you couldn’t see him, he’d likely steal the

food anyway.(I once lost half a Thanksgiving turkey like

that, but it was no experiment.) What the rigorous testing

done with scores of dogs of different breeds at

Portsmouth has proved scientifically is that our canine

[10] friends really do pay attention to what they’re doing — a

level of cognition that puts them in a category of

intelligence that can begin to be compared with primates.

“Dogs show some specialized skills in how they read

human communications, says Juliane Kaminski, one of

[15] the authors of the Portsmouth study. “This seems to be

a direct result of selection pressures during

domestication.” To put it unscientifically, they’ve been

man’s best friend so long, it’s in their blood. Kaminski

says she doesn’t know of any similar studies done on

[20] felines. But, then, we already know cats don’t really give

a damn what humans think.
