Biblatex format for Genes & Immunity

Here's a biblatex format for Genes & Immunity (a Nature imprint) which I needed recently:

The following code in the preamble does almost all of the hard lifting:

\usepackage[backend=biber,hyperref=true,doi=true,url=false,isbn=false,maxbibnames=6,minbibnames=6,sorting=none,firstinits=true,terseinits=true,autocite=inline,style=numeric-comp]{biblatex}
\renewbibmacro{in:}{%
  \ifentrytype{article}{}{%
  \printtext{\bibstring{in}\intitlepunct}}}
