How to exclude certain wordpress pages from cache – Hyper cache Plugin

Hi, I am developing a news section in my blog and I do not want my caching plugin (Hyper cache) to cache those pages. Caching is causing loading of the pages.

e.g I am calling news feed items from different rss sources at http://www.environmentabout.com/environment-news and http://www.environmentabout.com/science-and-technology-news but when I enable caching plugin, the pages do not load completely and some of the times the plugin caches blank pages. So everytime I request these pages, blank pahes load.

How do I exclude these pages from hyper cache so that these pages are always fresh?
