Sometimes verbatim, sometimes it looks like they've got a writer who makes them a little 'punchier', but I've never seen an original article there. Honestly, I've kicked myself for doing my PhD instead of creating a sciencedaily site - it's a hell of a racket. If I had only gotten there first.
I glance at it once or twice a week ~ the utility of the site is that you can usually parse out the publication and author, and then go search the actual paper and see for yourself.
Someone mentioned Science & Nature, both decent (I like to put the weekly Science podcast on my mp3 player and listen walking to work). The link for that is:
http://www.sciencemag.org/about/podcast.dtl Their downside is that they focus on stuff published in their own journal, so it's limiting.
NPR's Science friday (
http://www.sciencefriday.com/) is ok, but mostly focuses on a theme, rather than giving you the full buffet of the week's science.
Speaking of a theme, you should definitely know about radiolab (www.radiolab.org). These folks have found a very nice balance - it's half "this american life" and half "NOVA". Really great stuff with downloads available. Everyone I've turned on to this has dug it in a big way. They do need to fire the recording engineer, though, who seems not to have grasped the concept of "compression".
Lastly, since you asked about an internet resource, may I direct your attention to the absolutely fantastic scienceblogs.org.
This website is just kickass. It will keep you abreast of the new stuff in science (like sciencedaily.com), but with a slant given by the individual blogger, and with the added benefit of comments sections that can be extremely enlightening. So you've got the wiki-esque crowd of informed observers adding their thoughts to the story, and keeping the bullshit factor down. Absolutely awsome site.
