In the next beta there will be another way to do this, but right now you could insert this in your template file:
...just after your template's get_page_content(); tag.
Code:
<?php if (return_page_slug()=='news' && !nm_post_title("","",0)) { ?>
<a href="#top">Zurück zum Anfang</a>
<?php } ?>
...just after your template's get_page_content(); tag.
