title: Corrections and clarifications.
abstract: In Christopher Anderson's News & Comment article "Rocky road for Federal Research Inc." (22 Oct., p. 496), a comment from National Institutes of Health neuroscientist Michael Rogawski regarding Cooperative Research and Development Agreement (CRADA) delays did not refer to his own CRADA experiences, which he says were not characterized by inordinate delays. Rogawski was referring to the effect on scientists in general of the delays inherent in what he considers appropriate scientific and administrative review.
