The News story ‘Election results delight scientists’ (Nature 522, 264–265; 2015) stated that Gençay Gürsoy won a seat in the new Turkish parliament for the HDP. He did not; he is a member of the HDP assembly.

The News story ‘Earth science wrestles with conflict-of-interest policies’ (Nature 522, 403–404; 2015) erroneously stated that hydrologist Donald Siegel disclosed the provision of water samples by Chesapeake Energy Corporation only in a correction to his article. In fact, this information was included in the acknowledgements of his original paper.

Clarification

The News story ‘Earth science wrestles with conflict-of-interest policies’ (Nature 522, 403–404; 2015) did not make clear that Siegel’s findings related to gas production in general, and not just the process known as fracking. This has been clarified in the online version of the story.
