Moral and Ethical Issues Raised by Technological Success

Summary Should we do research in areas we may not be able to control? (eg, genetics, cloning, nanobots, intelligent machines?)

Will prolonging life through technology result in more disease in the overall population

Can we change medicine from treatment to prevention of disease

In defeating diseases, will technology change a human into a combination of man and machine - what does it mean to be “human”

How will we decide who gets the technology, especially in 3rd WorldSATAVA 7 July, 1999DARPA

And just what are these profound moral and ethical issues?

“The practice is contrary to human dignity and is criminal”     

French President Jacques ChiracClonaid scientist Brigitte Boisselier said a baby girl - nicknamed Eve - was born in the US after the genetic material from a woman's skin cell was fused with one of her eggs. Dr Boisselier said four other women were due to give birth to baby clones in the coming weeks - one in Europe, another in North America and two in Asia.

Demands grow for human clone ban Advocates argue cloning can help infertile couples

There are growing demands for a ban on human cloning after claims that a girl born on Thursday is an exact genetic replica of her mother.

                                 Clonaid scientist Brigitte Boisselier said four more clones will be born soon. French President Chirac has called on all countries to rally behind a Franco-German proposal for a global ban on human cloning which has been submitted to the United Nations.

US President George W Bush says the process is "deeply troubling".

Scientists remain sceptical of the success claimed by the Clonaid company, which is linked to a sect that believes aliens created humans by cloning 25,000 years ago.

But legislators in Britain and elsewhere say there has to be discussion and introduction of rules for the practice of scientific methods which could produce a cloned baby, even if Clonaid's claims are untrue.

“These technologies . . . are raising new moral and ethical morasses for us.”      Dr Ian GibsonBritish legislator

South Korean team demonstrates cloning efficiency for humans similar to pigs, cattle | Thersa Tamkins

After outlandish claims, a few media circuses, and some near misses by legitimate researchers, a team of South Korean researchers reports the production of cloned human embryos. The findings, were released Wednesday (Science, DOI:10.1126 /science.1094515, February 12, 2004).Wook Suk Hwang and Shin Yong Moon of Seoul National University used somatic cell nuclear transfer to produce 30 human blastocysts and a single embryonic stem cell line; SCNT-hES-1. Using 242 oocytes and cumulus cells from 16 unpaid donors, the group achieved a cloning efficiency of 19 to 29%, on par with that seen in cattle (25%) and pigs (26%).

Human embryos cloned

Chinese Cloning Control RequiredTuesday 16 April, 2002, 10:41 GMT 11:41 UK

Strict ethical guidelines are needed in China to calm public fears about new cell technologies such as cloning, the country's leading scientist said. Professor Ching-Li Hu, the former deputy director of the World Health Organization, was speaking at the Seventh Human Genome Meeting in Shanghai. His call follows recent reports that Chinese scientists are making fast progress in these research fields. One group in the Central South University in Changsa is said to be producing human embryo clones, while another team from the Sun Yat-sen University of Medical Sciences in Guangzhou is reported to have fused human and rabbit cells to make tissues for research.

Five "designer babies" created for stem cells

Five healthy babies have been born to provide stem cells for siblings with serious non-heritable conditions. This is the first time

"savoir siblings" have been created to treat children whose condition is not genetic, says the medical team.The five babies were born after a technique called preimplantation genetic diagnosis (PGD) was used to test embryos for a tissue type match to the ailing siblings, reports the team, led by Anver Kuliev at the Reproductive Genetics Institute in Chicago, US.The aim in these cases was to provide stem cells for transplantation to children who are suffering from leukaemia and a rare condition called Diamond-Blackfan anaemia (DBA)."It's a big step, because it gives people another option," says Mohammed Taranissi, at the Assisted Reproduction and Gynaecology Centre, London, UK, one of the team. "Before that the only option was to look in the siblings and immediate family to see if you had a match or alternatively to just keep trying [to have a baby which matches]."He told New Scientist that people trying to conceive a child naturally as a tissue match for a sick sibling had only a one in five chance. This method can also lead to terminations where the foetus is not a tissue match for the sibling."If you do it this way, the chance of finding a match is 98 per cent."'Unlawful and unethical' However, the use of this technology to provide a "designer baby" to treat an ill sibling is highly controversial.A UK couple involved in this study travelled to the US for treatment after the UK's Human Fertilisation and Embryology Authority (HFEA) ruled that they could not create a tissue-matched sibling as a stem cell donor to their son.In-vitro fertilisation (IVF) and tissue-typing was used in the US to give the Whitakers a perfectly matched baby boy to help their son

RENO, Nev. - On a farm about six miles outside this gambling town, Jason Chamberlain looks over a flock of about 50 smelly sheep, many of them possessing partially human livers, hearts, brains and other organs. The University of Nevada-Reno researcher talks matter-of-factly about his plans to euthanize one of the pregnant sheep in a nearby lab. He can’t wait to examine the effects of the human cells he had injected into the fetus’ brain about two months ago. “It’s mice on a large scale,” Chamberlain says.As strange as his work may sound, it falls firmly within the new ethics guidelines the influential National Academies issued this past week for stem cell research. In fact, the Academies’ report endorses research that co-mingles human and animal tissue as vital to ensuring that experimental drugs and new tissue replacement therapies are safe for people. Doctors have transplanted pig valves into human hearts for years, and scientists have injected human cells into lab animals for even longer.Biological mixing of speciesBut the biological co-mingling of animal and human is now evolving into even more exotic and unsettling mixes of species, evoking the Greek myth of the monstrous chimera, which

was part lion, part goat and part serpent. In the past two years, scientists have created pigs with human blood, fused rabbit eggs with human DNA and injected human stem cells to make paralyzed mice walk. Particularly worrisome to some scientists are the nightmare scenarios that could arise from the mixing of brain cells: What if a human mind somehow got trapped inside a sheep’s head? The “idea that human neuronal cells might participate in 'higher order' brain functions in a nonhuman animal, however unlikely that may be, raises concerns that need to be considered”.Mice with human brainsIn January, an informal ethics committee at Stanford University endorsed a proposal to create mice with brains nearly completely made of human brain cells. Stem cell scientist Irving Weissman said his experiment could provide unparalleled insight into how the human brain develops and how degenerative brain diseases like Parkinson’s progress.Stanford law professor Hank Greely, who chaired the ethics committee, said the board was satisfied that the size and shape of the mouse brain would prevent the human cells from creating any traits of humanity. Just in case, the committee recommended closely

monitoring the mice’s behavior and immediately killing any that display human-like behavior.Weissman, who has already created mice with 1 percent human brain cells, said he has no immediate plans to make mostly human mouse brains, but wanted to get ethical clearance in any case. A formal Stanford committee that oversees research at the university would also need to authorize the experiment.

Extending Longevity

Should humans live 200 years?

Life extension

Life extension consists of attempts to extend human life beyond the natural lifespan. So far none has been proven successful in humans. Several aging mechanisms are known, and anti-aging therapies aim to correct one or more of these: Dr. Leonard Hayflick discovered that mammalian cells divide only a fixed number of times. This "Hayflick limit" was later proven to be caused by telomeres on the ends of chromosomes that shorten with each cell-division. When the telomeres are gone, the DNA can no longer be copied, and cell division ceases. In 2001, experimenters at Geron Corp. lengthened the telomeres of senescent mammalian cells by introducing telomerase to them. They then became youthful cells. Sex and some stem cells regenerate the telomeres by two mechanisms: Telomerase, and ALT (alternative lengthening of telomeres). At least one form of progeria (atypical accelerated aging) is caused by premature telomeric shortening. In 2001, research showed that naturally occurring stem cells must sometimes extend their telomeres, because some stem cells in middle-aged humans had anomalously long telomeres.

Gaak

Courtesy Professor Noel Sharkey, Sheffield Unversity, London

"Thinking" robot in escape bid Scientists running a pioneering experiment with robots which think for themselves have caught one trying to flee the centre where it "lives". The small unit, called Gaak, is one of 12 taking part in a "survival of the fittest" test at the Magna science centre in Rotherham, South Yorkshire, which has been running since March. Gaak made its bid for freedom after it had been taken out of the arena where hundreds of visitors watch the machines learning how to repair themselves after doing daily battle. Professor Noel Sharkey said he turned his back on the drone, but when he returned 15 minutes later he found it had forced its way out of the small make-shift paddock it was being kept in. He later found it had travelled down an access slope, through the front door of the centre and was discovered at the main entrance to the car park when a visitor nearly flattened it with his car.
