A group which advises the US government on biosecurity has explained why it wants two research papers on H5N1 bird flu to be censored.
Two scientific research teams have modified influenza strains to create mutant avian influenza viruses that can be transmitted efficiently between mammals. In one case, the virus remained highly pathogenic.
After more than a decade of waiting, the first results of a trial involving human embryonic stem cells have been published in a medical journal.
The Lancet reports how two women in the USA with eye disease were injected with stem cells and both apparently showed some slight improvement in vision. The company Advanced Cell Technology (ACT) says the patients are doing well four months on from the trial.
