    In the News & Views article 'Getting close to the action' originally published online (Nature Nanotech. 2012), the signal-to-noise ratio determined by Cui and co-workers was given incorrectly as '7'; it should have read 'over 100'. This error has now been corrected in all versions of the News & Views article.'
