Update your sitemaps. Use the news pages, and then submit your sitemaps again. You don't have to submit the new pages, individually. Then you can find your sitemaps.
Sitemaps give something that the Google robots can crawl. The most effective way to have sitemaps is to add your sitemap to a Google Webmasters Tools account - google.com/webmasters/tools/ that is free to set up. Once you have done this Google is able to crawl your website much easier finding deeper content that can be displayed on Google.
