voted Monday to approve controversial plans to allow
the use of animal-human embryos for research.

for almost 20 years, have provoked stormy debate -- pitting

Two days of House

include the first major vote on revising British abortion
laws since 1990.
chief David Cameron -- and several cabinet ministers --
advocate lowering the 24-week limit for abortions in
Britain. Legislators will vote on whether to retain
the current limit or lower it to 22, 20, or 16 weeks.

DNA. A burst of electricity is then used to trick the
egg into dividing regularly, so that it becomes a very
early embryo, from which stem cells can be extracted.
the embryos would not be allowed to develop for more than
14 days, and are intended to address the shortage of human
embryos available for stem cell research.
''I believe that
we owe it to ourselves and future generations to
introduce these measures, and in particular to give our
unequivocal backing, within the right framework of
rules and standards, to stem cell research,'' Brown

embryos and by 286 to 223 against a separate proposal
covering a specific type of animal-human embryos.
Alert, a science watchdog opposed to the proposed changes,
claims the laws could lead to the creation of genetically
modified ''designer babies.''
''Once we start
down the road to human genetic modification, it will be
very difficult to turn back,'' the group warns in a briefing
paper for lawmakers.
Conservative lawmaker Edward Leigh, who tabled an amendment
seeking to ban the practice, said the technique was a step
too far for science.
''In many ways we
are like children playing with land mines without any
concept of the dangers of the technology that we are
handling,'' he said in the House of Commons.
Lovell-Badge, a stem cell biologist at the U.K. National
Institute for Medical Research, said greater understanding
of genetic diseases at the cellular level could speed
the development of treatments.
''We have to be
careful not to overhype it, because we can't promise
anything will work, but if it does work then there will be a
lot more understanding. More understanding is crucial
to developing new treatments,'' he said.
Fertilization and Embryology law, which regulates all
stem cell and embryology research, was drafted in 1990.

screening of embryos for genetic characteristics to create
''savior siblings.'' These are cases where parents
seek to have a child with specific non-diseased
characteristics to help a diseased older sibling

Authority with clearer guidelines. The decisions are
