There had been talk of waiting for Congress to act, but Obama is expected Monday to undue* undo Bush’s ban on federally funded research using embryonic stem cells. Congress is still expected to pass legilsation* legislation later this year to prevent future presidents from reinstating the ban. The lifting of the ban would be effective immediately, so aspiring Octomoms be aware: very soon there will other options for those extra embyros.
*Apologies for the typos. TGIF.
