Chickens that have been genetically modified to produce human proteins in eggs can offer a cost-effective method of producing certain types of drugs. The study which initially focused on producing high quality proteins for use in scientific research, found the drugs work at least as well as the same proteins produced using existing methods. The study was carried out at the University of Edinburgh's Roslin Institute and Roslin Technologies, a company set up to commercialise research at The Roslin Institute and is published in BMC Biotechnology. High quantities of the proteins can be recovered from each egg using a simple purification system and there are no adverse effects on the chickens themselves, which lay eggs as normal. According to researchers, the findings provide sound evidence for using chickens as a cheap method of producing high quality drugs for use in research studies and, potentially one day, in patients. Notably, eggs are already used for growing vi

Analysing the DNA may help predict whether a person will live longer or die sooner than average, according to a study. Researchers at the University of Edinburgh in the UK analysed the combined effect of genetic variations that influence lifespan to produce a scoring system. People who score in the top 10 per cent of the population might expect to live up to five years longer than those who score in the lowest 10 per cent, they said. The findings, published in the journal eLife, also revealed fresh insights into diseases and the biological mechanisms involved in ageing. "If we take 100 people at birth, or later, and use our lifespan score to divide them into ten groups, the top group will live five years longer than the bottom on average," said Peter Joshi from the University of Edinburgh's Usher Institute.

A Chinese researcher claims that he helped make the world's first genetically edited babies twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life. If true, it would be a profound leap of science and ethics. A US scientist said he took part in the work in China, but this kind of gene editing is banned in the United States because the DNA changes can pass to future generations and it risks harming other genes. Many mainstream scientists think it's too unsafe to try, and some denounced the Chinese report as human experimentation. The researcher, He Jiankui of Shenzhen, said he altered embryos for seven couples during fertility treatments, with one pregnancy resulting thus far. He said his goal was not to cure or prevent an inherited disease, but to try to bestow a trait that few people naturally have an ability to resist possible future infection with HIV , the AIDS virus .
