SciTech Daily has been serving up Science and Technology News since 1998, and doing it quite well. Its blend of content just might keep you looking around the site when you really should be doing other things.
I particularly enjoy the Biology and Space sections, though the Technology, Earth, Science, Chemistry, Health and Physics sections are all worth a look. The Breaking Science and Technology News and Resources sections have terrific links to outstanding sources on the web. You can also subscribe to the newsletter to receive an email digest of new articles posted to the site.
