You might use tiles instead of lists. A lot of space is used up for the categories, a logo could do the same (I assume the categories rarely change).
Colors could be used to indicate whether something updates weekly, monthly, or daily. Brightness could be used to indicate that something is new (maybe also a border for everything new for the user since the last login). Tiles could be dynamic in size, so the whole title and other relevant information fits in. Day, month, year, title and other info should be easy to distinguish at a glance (through font, borders, backgrounds...), so it's easier to focus on whatever someone looks for.
You could leave some space on top for a menu, where people can sort by date, title, category and so on, to create a custom view (and maybe also go back to list view). There, they could also find info on what the symbols, colors and so on mean.
Every graphical feature (color, text, border, brightness, corner...) should be easy to ignore when not needed and easy to look for when needed. So that one finds dates, titles, categories and other relevant information very fast and effortless.
If you have extra time, an alphabetical list with keywords from the titles and categories, maybe differently large for frequency, can help quickly find all articles where the title includes that keyword. You just need to exclude words no-one searches for in the context, like of, and, a, an, or, the and so on.
And you can reserve some extra large space for the newest article - or an especially important one.
If the titles are not too clear, you could have a little summary or excert appear when hovering over a tile, or at the bottom of tile (maybe as an option).
On a side note, if you have a list view, don't put more than 1 item in 1 row. rather put the date and other information besides the title. This is much easier to parse, and therefore much more practical. More boring, but faster and easier to work with.
