Can you suggest a site that has useful, informative articles?

I want to know more about random topics for writing my personal statement for universities. Preferable about hot topics like biowarfare, point shaving in sports scandals, medical breakthroughs, teenage , gayism etc. Please don't suggest a site like wikipedia where you have to search for stuff since I don't have a lot of time. A site where you could just easily click through to get an article would be awesome! thanks in advance : )
