Scientists have discovered one of the rarest minerals on Earth in a Wisconsin impact crater. Aaron Cavosie of the University of Puerto Rico, and member of the NASA Astrobiology Institute Team at the University of Wisconsin, brought students to an impact site in Rock Elm, Wisconsin to collect s...
The demand and supply of the individual rare-earth elements have to be equal at any time. Otherwise there will be shortages or excesses of some elements. The REEs occur in different ratios in minerals and ores, reflecting the natural abundance of the elements. For instance, neodymium is much...

Once he had tinkered with the system so it would respond to the levels of phenylalanine typically found in the blood of a patient with PKU, Guthrie, who knew that the relevant metabolites were stable in dried blood, had the transformative idea of developing a universal PKU screening test. ...

In this way, the use of stable minerals (or the chemical elements they contain) are considered to resist weathering in soils, and have been used to estimate the degree of uniformity material. In this sense, Alexander et al. [25] and Chapman and Horn [26] proposed Zr and Ti. The ...
