Top Ten Discoveries of the Mars Rovers

eldavojohn writes "Space.com brings us the top ten discoveries of the Martian rovers that landed there in 2004. They were expected to last three months but, as Slashdot has covered time and time again, they have lasted over three years. From minor discoveries about the formation of Mars to images of atmospheric phenomena, to final and definitive proof of a Mars with water, these two robots have definitely reserved themselves a place in the history books. Pending a dust storm, they may not even be done with their mission yet."

I recall hearing that recycling costs $8 billion a year, as a result of subsidizing the recycling of materials that have a net negative economic impact, because using new materials instead would be cheaper, easier and require less industrial processing to make.

That's actually the case for everything but metals. As Penn and Teller put it, when recycling becomes so efficient that bums on the street will do the sorting, then you'll know it's actually beneficial for society.
