[Tex/LaTex] Change bibliography format in a revtex4-1

Question

I'm writing a Lab report for one of my assestments, using revtex4-1 document class. This class, in particular, displays the bibliography at the bottom and breaks columns with a line crossing them.

I need my bibliography be shown within columns, and not breaking them. Is a particular requirement of my teacher (not kidding). I tried to move on to a new document class (article), but this bring more troubles because it has a different abstract enviroment.

\documentclass[reprint,
showpacs,preprintnumbers,showkeys,
amsmath,amssymb,
aps,
pra,
letterpaper,twoside]{revtex4-1}
\includepackage{natbib}
\begin{document}
\section{A section}
Science

\bibliographystyle{apsrev4-1}
\bibliography{/home/juan/Escritorio/Jabref/prct2mod.bib}
\end{document}

This is the way my document class shows the bibliography:

I need to be shown like this:
