Getting Pagination to work in custom query

I have tried a number of things, including shutting off all plugins, but I cannot get pagination to work.

<?php
    // WP_Query arguments
    $paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
    $args = array (
      'category'               => '44',
      'pagination'             => true,
      'posts_per_page'         => '10',
      'paged'                  => '$paged',
    );

    // The Query
    $news_query = new WP_Query( $args );

    // The Loop
    if ( $news_query->have_posts() ) {
      while ( $news_query->have_posts() ) :
        $news_query->the_post(); ?>
        <h2><?php the_title( ); ?></h2> 

      <?php endwhile; ?>

      <?php next_posts_link('&laquo; Older Entries') ?>
      <?php previous_posts_link('Newer Entries &raquo;') ?>

    <?php }

    else {
      // no posts found
    }
    ?>

I read this forum post and the codex but no dice.

Thank you so much for any help.
