How do you get the WordPress loop to show only posts that exaclty match an array of categories, not just one?

I am trying to display all news and events posts (different cateogries based on Publisher) on a banner across the top of the website but am trying to define there parent category, too. Any ideas?

I have found this:

$query = new WP_Query( array( 'category__and' => array( 2, 6 ) ) );

But I really need to be a slug/string, not an int

Found it! Check the post here, Here is the function:)

<?php get_term_by( $field, $value, $taxonomy, $output, $filter ) ?>

And here is an example: 

// fetching the category id's 
<?php $theCatId = get_term_by( 'slug', get_the_title(), 'category' ); ?>
<?php $newsCat =  get_term_by( 'slug', 'news', 'category' ); ?>

// the custom loop
<?php $args = array( 'post_type' => 'news', 'category__and' =>  array($newsCat->term_id, $theCatId->term_id) );?>
<?php $query = new WP_Query($args); ?>
<?php if ( $query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post(); ?>
    // the content
<?php endif; endwhile; ?>

Just realised... I don't think it is using the news category in the loop, only the one converted to an int. I haven't set the ID of it. Oops. I'll change that shortly. :$
