New ethical grounds

others were seriously injured. Other workers risked their lives to fetch the smallest cubs from the breeding centre and carry them to safety. Two of the centre’s 53 pandas were injured and six went missing, but four returned later. However, staff managed to transport eight pandas to Chengdu where they were flown to Beijing. Conservationists hope the arrival of the animals at Beijing zoo will highlight the damage caused to their habitat and encourage donations to the Wolong sanctuary during the forthcoming Olympic games. The government has arranged emergency supplies of bamboo and other foodstuffs to the pandas in Sichuan as local people are no longer able to collect it following the earthquake, the China Daily reported. “When we saw the rock slides we were really worried,” said Lu Yong, who has helped care for the animals that were sent to Beijing and travelled with them. “In a disaster the first thing we think of is the pandas and how to get them to safety. They were very scared and disturbed when the earthquake happened. They needed support from their keepers before they would eat again.” Wang Pengyan, the deputy chief of the reserve, said the animals’ appetite was back to normal — 10–18 kg of bamboo a day plus milk, carrots, apples and steamed buns. The two-year-old pandas in Beijing went on show to the public this month, but Wang said it could take many years for their permanent home at Wolong to be restored – many buildings have collapsed or are unsafe, a new road to the centre is badly damaged, and vast areas of bamboo have been destroyed. He said two of the six pandas that fled in the earthquake were still missing. “Maybe when the mountain collapsed they could have been buried, but we hope they have escaped into the wild. They have very close ties to the workers and keepers,” he said, suggesting they might return of their own accord. Yang Baijin, the secretary general of the China Wildlife Conservation Association, said many Sichuan panda reserves had been affected by the earthquake, which would make preserving the species more difficult. It is thought that only around 1,600 pandas remain in the wild. Scientists in Britain will be allowed to create hybrid human–animal embryos after parliament voted overwhelmingly in favour of changes to the law governing stem cell research last month following a lengthy and polarised public debate. During passionate exchanges in parliament, critics of the proposed embryo research proposals warned that Britain “was crossing a Rubicon” and risked becoming a “rogue state”. But they were heavily outnumbered by those who argued in favour of the potential of stem cell research using hybrid embryos between animal and eggs and human nuclei for a strictly limited period of time. Members of parliament also voted against an amendment to ban the creation of saviour siblings — a process where parents use fertility treatment to select an embryo that is a genetic match of an older child who has a disease that may be treatable by stem cells from the new sibling. Following the votes, which were conducted on personal rather than party lines, Britain is now set to be at the legal forefront in stem cell research. Scientists had complained of being hampered by a lack of human eggs available for research. As a result of the measures introduced in the Human Fertilisation and Embryology Bill, they will be able to boost stocks by creating hybrid embryos using animal eggs. Health charities and scientists carried out a successful lobbying campaign opposing the position of some religious leaders who had publicly opposed the bill. In parliament, opposition to the proposed legislation was led by Conservative MP, Edward Leigh. He said: “This does cross the ultimate boundary between humans and animals. There is nobody in this house who denies how wonderful it would be if there was some easy way we could cure these diseases. But some things The British parliament’s backing for research on human–animal hybrid embryos has created an ethical ‘intensity’ for the research watchdog. Nigel Williams reports. New ethical grounds are so unnecessarily dangerous that they should be banned.” “No other country is going down this route. In these terms in embryology we would almost be like a rogue state.” As it now goes into law, the pressure rises for the regulatory body, the Human Fertilisation and Embryology Authority. But its leader, Lisa Jardine, the new chair of the authority, is relishing the challenge. Jardine is professor of renaissance studies at Queen Mary College London, but is excited at being at the meeting point of science and religious conviction. But she also realises regulators will sometimes have to say no. Regulators “ought to go hand in hand with those they regulate most of the time, but from time to time they will have to upset people”. When the debate over the bill began, she believes that, once the science of the hybrid embryos had been explained, only those dogmatically opposed thought hybrid embryos were scary Frankenstein monsters. But she had hoped that more information would be put into the public domain about stem cells. “It’s quite unexpected to me how ethically intense this all is,” she says. But she hopes to be leading future debates.
