Getting Sticky posts to work on cutom Query

Hi,

I have created a custom query which displays News content in a specific area on the frontpage.

I would like to be able to have the Sticky post feature work so that any “Sticky” posts remain at the top of the posts.

How can I get this to work. This is the code I am currently using:

$args = array(
								'post_type' => 'post',
								'category_name' => 'nashakaranews',
								'posts_per_page' => 5,
								//'post__in' => get_option('sticky_posts'),
								'cat' => -270,
							);
							$query_news = new WP_Query( $args );
							if ( $query_news->have_posts() ) {
								echo '
<ul>';
								while ( $query_news->have_posts() ) {
									$query_news->the_post();
									echo '
<li>';
										?>
										<a>" title="<?php the_title(); ?>">
										<?php
										the_post_thumbnail( 'event' );
										?></a></li>
</ul>
