Here are some items:

• Want to make the most of Google? Wikipedia has a good list of all Google services and tools.
• I didn't see anything too eye-opening here, but here's an article with top ten things that MS Word users should know.
• Cash is finally on the way out... in the UK at least where debit card use has overtaken cash.
• A good night's sleep boosts long term memory.
• The machines are closer to taking over: check out the video of the self-assembling robot chair. I can't imagine how useful that is.
• An interesting demographic view: US maps of religion concentration.
• You think gas prices are bad? How about going to Venezuela, where gas is $0.14/gal? Wait, that's actually much better!
• And also, a good night's sleep boosts long term memory.
