Shopify allows you to set up multiple unique blogs. One way to achieve your goal would be to setup a separate 'blog' for each section.
A blog in this case consists of two layouts - a list and an article.
Each blog could have its own link in the main menu making it appear as a different section.
The blog list and article templates are very basic and don't allow for much customization through the UI.
You can, however, customize the underlying templates using css/html/liquid.
