At issue is a series of experiments described in Thursday's issue of the journal Nature, in which scientists at Advanced Cell Technology (ACT) in Worcester, Mass., described a method for making stem cells without harming a human embryo. The basic facts of the report remain unchallenged.
But in an unusual move yesterday, Nature corrected wording in a lay-language news release it had distributed in advance and posted clarifying data it had asked the scientists to provide.
At the core of the battle is a widely distributed e-mail from Richard Doerflinger of the U.S. Conference of Catholic Bishops, who raised three issues.
