Have only been reading this thread sporadically of late, was about to post link about this, decided to search in page for 'scroll' first - ya beat me to it. Here is 2nd link anyway:

[i]"Professor, great news! We began reading the first scroll, it opens with a discussion about '[url=http://www.imdb.com/title/tt0079470/quotes]what have the Romans ever done for us?[/url]' -- truly remarkable material!"[/i]

According to this, the metal quickly loses electrons to water and then metal clusters of positive ions burst apart due to repulsion.

Wonder if the kidney-disease-proneness (admittedly this may be more a function of domestic cats living much longer than their wild ancestors/brethren) is related to the marvelous adaptation that allows most cat species to drink salt water if fresh is in short supply?
