The News story ‘Phage therapy gets revitalized’ (Nature 510, 15–16; 2014) mischaracterized the CRISPR mechanism for tackling antibiotic-resistant microbes. It should have said that the phage injects DNA into the bacterium, which then transcribes it into RNA. And in the News story ‘Chicken project gets off the ground’ (Nature 509, 546; 2014), the mentions of ‘guinea fowl’ should have read ‘jungle fowl’.
