Scientific research at the Centre of the Physics of Materials, a mixed venture of the Higher Council for Scientific Research (CSIC) and the University of the Basque Country (UPV/EHU) in Donostia-San Sebastian, has enabled the discovery of a new physical phenomenon that affects the surfaces of illuminated metals. The conclusions of the research have been published in the journal Nature.

While metals like copper, gold, nickel and uranium have been center-stage in the recent surge of commodities exploration and investment excitement, tin, the duller cousin, has largely been considered unworthy of notice. In the last six months, however, tin prices have risen by 40%.

A limitation in using hydrogen as a fuel in hydrogen-powered vehicles is the difficulty involved in storing it in a cost-effective and convenient manner. While it is possible to store hydrogen using metals, the resulting products often can be prohibitively expensive and cause environmental problems.

A new study provides evidence that the last inhabitants of Christopher Columbus' first settlement desperately tried to extract silver from lead ore, originally brought from Spain for other uses, just before abandoning the failed mining operation in 1498. It is the first known European extraction of silver in the New World.
