My comment:
(a) The report is distributed by Associated Press.
(b) Ames Laboratory
http://en.wikipedia.org/wiki/Ames_Laboratory
(a United States Department of Energy national laboratory located in Ames, Iowa; on the campus of and perated by Iowa State University)
(c) One may start reading at the paragaph that begins with " In the United States, mining company Molycorp Minerals." (The first part talks about China restricting export that we are all familiar with.)
The second part of the report talks about magnets/batteries made of neodymium (a rare earth) as well as non-rare-earth metals.
(d) The report quotes Mr. Iver Anderson as saying, "Essentially, we are looking for the Lake Wobegon of magnets. It only needs to be 'good enough.' It needs to be 'above average.'"
Read (i) the opening paragraph, (ii) section 1 Name and (iii) section 6 The Lake Wobegon effect ("all the children are above average") in
Lake Wobegon
