I check quite a number of science-related sites for updates, and I'd love to be able to aggregate their news to expedite my checking process. Is anyone familiar of RSS feeds out there that already aggregate all this information? How do you keep up-to-date on all the science news? If what I'm looking for doesn't exist I will end up writing an aggregator myself for all the respective sites, including those that don't have RSS feeds (which is a lot of them). Thanks.
