Here are some of the most interesting research papers to have appeared in top science journals last week. (Subscribe to Science For All, our weekly newsletter, where we aim to take the jargon out of science and put the fun in. Click here.) Interspecies chimera Scientists have now grown monkey embryos containing human stem cells for the first time, raising several ethical questions. Fertilised eggs extracted from monkeys ( Macaca fascicularis) were injected with human extended pluripotent stem cells. Out of the injected 132 embryos, three survived 19 days after fertilisation. Scientists hope that such hybrids could be used as models for drug tests and to grow organs for transplants. Expressing concern, Julian Savulescu and Julian Koplin from the University of Melbourne wrote in a statement, “The challenge for chimera research is that there is n ....

How should mitochondrial donation operate in Australia? Appeared in BioNews 1090 Australia is on the cusp of legalising mitochondrial donation. Following a series of public consultations – the most recent of which proposed an Australian model for mitochondrial donation – a bill for the necessary law reform has passed two readings in parliament, and will go to a conscience vote in the next few months. This bill is the culmination of several years of debate about whether the procedure should be permitted. However, the need for discussion is not over. Australia now needs to consider how mitochondrial donation might best be implemented. The proposed Australian model resembles the dual licensing system in the UK (the first country to legalise mitochondrial donation). In Australia, just one clinic will be licensed to offer mitochondrial donation during the first phase of the model (which is expected to last 10-12 years.) Each patient seeking to use the service will a ....
