With soaring oratory, President Obama on Monday removed a substantial practical nuisance that has long made life difficult for stem cell researchers. He freed biomedical researchers using federal money (a vast majority) to work on more than the small number of human embryonic stem cell lines that were established before Aug. 9, 2001.
In practical terms, federally financed researchers will now find it easier to do a particular category of stem cell experiments that, though still important, has been somewhat eclipsed by new advances.
