The News story ‘Scientists probe Zika link to birth defects’ (Nature 530, 142–143; 2016) wrongly stated that at least seven countries have shown abnormal rates of microcephaly; this has happened only in Brazil. In addition, the article implied that 404 confirmed cases of microcepahly in Brazil could be linked to Zika virus — only 17 of those 404 have been linked so far. Finally, the correction note for the Editorial ‘Blue future’ (Nature 529, 255–256; 2016) omitted to say that the carbon sequestration in question was by living organisms in the oceans.
