This is a press release from the AIP announcing the winners of the awards for best science writing. There are some really good science essays here. I would bring your attention to Tim Folger and his award in the Journalist category. The article, published in Discover, is actually quite interesting and provocative. It was based on an interview with Roger Penrose, and of course dealt with one of the most fundamental issues surrounding quantum mechanics. It also contains a description of one of his proposed experiment at detecting the quantum superposition using mirrors, which is currently being tested by Dirk Bouwmeester at UCSD.
The proposal for this experiment was published a while back in PRL, and you can find the arXiv version here.
