Emulates the look of a Nature Letter. Pretty straightforward. See example.tex for implementation.
Nature print is typeset using the font Minion Pro.
This font is no longer supported by arXiv.
The closest free and arXiv-supported font I could find (which should be availble by default with a typical LaTeX installation)
is Palatino. This font - along with its Math equivalent - is niceley implemented with the mathpazo package.
