Added LiveScience.com to the RSS feed page so check it out.
LiveScience.com is an awesome site, full of information about, well, science: Animal World, Human Biology, Forces of Nature and Science of Fiction, to name a few.
I also added one from Technovelgy.com, an awesome site. Not only does it list the latest news and reports, it also has a repository of past articles. This repository is good for anyone doing research on a particular subject or as a writer looking for information.
