There is no "unbiased news." Period.
If what you want to do is get information without an overt bias, then yes, NPR is fairly good. Others have recommended The Economist, I second that. I would recommend getting your news from a variety of sources (preferably not American-centric, if you wish to hear international news).
I tend to lean heavily on NPR, The Economist, and the NY Times (the last two are seriously contradictory, but I find that to be useful). I have heard good things about The Atlantic, although I cannot vouch for it myself.
