Obama verruimt stamcelonderzoek

From tiny embryonic cells to the large-scale physics of global warming, President Barack Obama urged researchers on Monday to follow science and not ideology as he abolished contentious Bush-era restraints on stem-cell research. 'Our government has forced what I believe is a false choice between sound science and moral values,' Obama declared as he signed documents changing U.S. science policy and removing what some researchers have said were shackles on their work.
