AbstractIn this paper, I analyze the role of metaphors in public science communication. Specifically, it is a case study of the metaphors for CRISPR/Cas9, a controversial biotechnology that enables scientists to alter the DNA of any organism with unprecedented ease and has raised a number of societal, ethical and legal questions concerning its applications – most notably, on its usage on the human germline. Using a corpus of 600 newspaper articles from the British and German press, I show that there are striking differences in how these two European countries construe CRISPR in public discourse: the British press promotes the image of CRISPR as a word processor that allows scientists to edit the DNA, replacing spelling mistakes with healthy genes, whereas the German press depicts CRISPR as genetic scissors and thereby underlines the risk of mutations after cutting the DNA. I suggest that this contrast reflects differences in the legal frameworks of the respective countries and may influence the attitudes towards emerging biotechnologies among the British and German public.
