An aside: If you are not reading Nature you may be missing out on a lot. I would guess the same applies to Science.
Only the back half of Nature is actual research papers, which often are indeed very slow going. The other half is science news written clearly - it's fascinating, not a chore at all - and with a level of knowledge and sophistication unmatched elsewhere (AFAIK), and most importantly it will completely change your perspective: There is a world of research and knowledge that you won't even know exists if you read the more 'popular' science press.
A little time reading Nature will save you much more time reading less informative publications.
