Are there multiple custom post types in BuddyPress Scholar?

I just watched the great video at http://vimeo.com/9554408 and it seemed that there were news items and blog posts, according to the narrator. She described putting news items on the home page as separate from blog posts.

Does this mean you have different post types for news-related items and for blog posts? If not custom post types, how does this mechanism work?

Thanks!
