Need something interesting to read

I could use some good sites or forums to read up on some cool interesting stuff. Like new inventions, fun news or scientific theories kind of stuff. Anybody know something?

Download "Stumble Upon" : StumbleUpon - Welcome to StumbleUpon and then it will ask you to check all your interests and give an email address and then after that you'll have a stumble toolbar at the top and click "stumble!" at the top left and it will take you to a random website that fits your interests. It sounds lame but its kinda fun and interesting
