Hydrogen lines crossed
The words on the cover of our 7 October issue need clarification. The
issue contained two independent papers on hydrogen. The cover words 'Melting
hydrogen' and the image relate to 'A quantum fluid of metallic hydrogen
suggested by first-principles calculations'(Bonev et al., p. 669).
'A new superfluid awaits discovery' relates to 'A superconductor to superfluid
phase transition in liquid metallic hydrogen' (Babaev et al., p.
666). Apologies to both sets of authors for the confusion.
