Who writes Nature’s “News & Views”?
From the Nature guide on Other Submitted Material:


  
  News &amp; Views
  These articles inform nonspecialist readers about new scientific advances, as reported in recently published papers (in Nature and elsewhere). This is a commission-only section.
  


So the articles are selected and commissioned by Nature editorial staff, and written by invited authors. A quick look through recent News &amp; Views articles finds contributions from scientists and science writers (including former Nature writing / editorial staff).
