[Tex/LaTex] Minipage – space between two columns and aligning

beamerminipagevertical alignment

Here is the deal. I want both of them starting from the very same line and perhaps increase the distance between them. I really cannot remember wheater s.th. chaged after adding \setbeamercovered{transparent}

    \documentclass{beamer}
    \usetheme{Berlin}
    \usecolortheme{beaver}
    \usepackage[utf8]{inputenc}
    \usepackage[T1]{fontenc}  


    \setbeamercovered{transparent}

    \title{3D-Lithography}

    \begin{document}


    \begin{frame}
    \frametitle{Advantages of 2-PP to 1-PP}
    \setbeamercovered{transparent}
     \noindent\begin{minipage}{.45\textwidth}
      Basic Problems of Single-Photon Polymerization:
      \begin{itemize}
      \item layer-by-layer type of manufacturing (limits possible geometries)
      \item suppression through undesired quenching of radicals
      \item diffraction limits
      \end{itemize}
     \end{minipage}
    \pause
     \begin{minipage}{.45\textwidth}
       Optimization by Two-Photon Polymerization:
       \begin{itemize}
       \item true 3D-Process (random geometries) 
       \item radical quenching avoided
       \item small excited spots\\
      $\Longrightarrow$ smaller structures possible
     \end{itemize}
     \end{minipage}
    \end{frame}
    \end{document}

As JLDiaz mentions, you can control the vertical alignment of minipages with an optional argument. Another way would be to use beamer columns. Both are demonstrated below. Note the [t] for the columns environment, which top-aligns the columns.
