As Phevans suggested there was a problem with the widths on the columns. I have modified the style.css file, click here to download it. I also noticed that the paragraph spacing is a bit odd (you get the same width between paragraphs that you get between lines) so I have modified that too.
To install this file you will need to place it in: your_wordpress_directory/wp-content/themes/binary-news-10
I have not changed this blogs theme to Binary News yet as I’m adding some further modifications to the css.
