From time to time I run across a science article which doesn't fit very well into existing threads and it seems a waste to start a new thread each time for a few posts.
As such, here's a new thread for the science articles you aren't able to categorize otherwise.
I'd also like to leave the false gods of AGW out of here, thankyouverymuch.
Sand is a cheap and easy to find water filter. It's also not a very good water filter. But a new development--coating sand in graphite--could make it possible for everyone in the world to have easy access to clean water.
It says 'as good as an activated carbon filter'. So caveat emptor. (Activated carbon does a lot of things, but it needs to be used in conjunction with other technologies depending upon the contamination present and distribution system being used.)
The issue with most filters isn't their filtering capacity - it's the regular replacement of the media required to remove the accumulation of contaminants. You get a nice accumulation of organics before the filter media, and that actually breeds contaminants. (Large water treatment plants will use a backwashing process. Fun to see, but wastes a lot of water.)
If you're using a Brita filter: replace it often.
But the graphite thing is interesting.

I stand corrected it's not limited to only a person's view of science by a movement's view of approved science.
I'd say: if it's science related to the topic of Global warming, then the appropriate spot would be in those existing topics.
(Some of us have interests in science other than reading the same old arguments between the same people over and over again. Saying something in four different threads isn't going to convince anyone any more than saying it in three threads, but MIGHT get you put on the 'ignore' list.)
