Science: A three-judge panel of the US Court of Appeals for the District of Columbia, which had on 9 September lifted a judge’s ban on stem-cell research, has now decided to allow federal funding for human embryonic stem-cell research to continue while the court considers a judge’s decision that such research is illegal. US District Judge Royce C. Lamberth had ruled in August that a 14-year-old congressional spending restriction prohibited federal support for all research on embryonic stem cells. The National Institutes of Health, however, maintains that the restriction prohibits for research purposes only the creation of embryos, not the use of existing embryos. It could take more than a year for the legal case to be resolved.
