Comment on "Ribose and related sugars from ultraviolet irradiation of interstellar ice analogs"

Abstract

Meinert et al (Reports, 8 April 2016, p. 208) reported the formation of prebiotic molecules, including ribose, in an interstellar ice analog experiment. We show that if their experimental procedure is accurately described, much or most of their products may have been formed during their analysis process, not in the parent ice.
