CELL BIOLOGY:
Nobel Laureates Lobby for Stem Cells
Gretchen Vogel
Eighty Nobel Prize winners have signed a letter urging President Bush to allow government-funded researchers to work on human pluripotent stem cells. In a letter faxed to the White House on 22 February, they argue that the cells--which have the capacity to develop into any tissue type--could help treat a variety of diseases. The Bush Administration is under pressure from antiabortion groups to block federal funding for work on embryonic stem cells.
