Yes, it is. From the documentation:

    Section headings don’t set marks for the running heads in the article
    style, only in the amsbook style.

The following seems to work:

\let\origsection\section
\renewcommand{\section}[1]{\sectionmark{#1}\origsection{#1}}

% redefine sectionmark
\renewcommand\sectionmark[1]{\markboth{\thesection. #1}{\thesection. #1}} 

% clear any old style settings
\fancyhead{}
\fancyfoot{}

% define new headers/footers
\lhead{\scshape\nouppercase\rightmark}

But it may be a bit fragile with section headers close to page boundaries.
