A LINE IN THE TEST TUBE: The Debate over Stem Cells

with Ramesh Ponnuru, Irving Weissmanvia Uncommon Knowledge
Monday, September 20, 2004

Proponents of embryonic stem cell research proclaim the potential of the research to find cures or treatments for many diseases such as Parkinson's and Alzheimer's. Opponents say the use and destruction of human embryos in the conduct of this research are immoral. In 2001, President Bush announced a ban on federal funding involving any new lines of embryonic stem cells. But calls to lift the ban continue, as do movements to increase funding at the state level. Which side of the debate is right? Is embryonic stem cell research ethical or not? Peter Robinson speaks with Ramesh Ponnuru and Irving Weissman.

DIVISIONS AND DECISIONS: The Ethics of Stem Cell Research

with Irving Weissmanvia Uncommon Knowledge
Tuesday, September 25, 2001

In August of 2001, President Bush announced his decision to limit federal funding of stem cell research to already established lines of embryonic stem cells, while forbidding funding for any research that required the destruction of additional human embryos. But his decision ended neither stem cell research nor the debate over the ethics of such research. How do we weigh the medical benefits of this research against the destruction of embryos? Where do we draw the line on research using human embryos and are we on a slippery slope toward even more controversial research?
