A main conclusion of this work by Robars et al. is that a piece of Iceland spar (optical calcite) can be used in a simple manner to find the direction to the Sun using polarized light, even when the Sun is obscured by clouds or just below the horizon, which supports the possible role of the renowned sunstones discussed in Viking Sagas. They propose a method of using an opaque spot on the incomi...

We compared lifetime and population energy budgets of the extraordinary long-lived ocean quahog Arctica islandica from 6 different sites—the Norwegian coast, Kattegat, Kiel Bay, White Sea, German Bight, and off northeast Iceland—covering a temperature and salinity gradient of 4–10 C (annualmean) and 25–34, respectively. Based on vonBertalanffy growth models and size–mass relationships, we compu...

The mineralogy of an unusual calc-silicate nodule brought to the surfaoe by the 1902 eruption of La Soufriere volcano on St. Vincent (Lesser Antilles arc) is described. It consists of the crystalloblastic mineral assemblage fassaite pyroxene + grandite garnet + wollastonite + anorthite t calcite. The pyroxene is more aluminous (Al2O3 : 19.66 weight percent) than any previously described from te...

Icelandic surgeons provide a wide range of modern surgical services with excellent results. How can a nation of fewer than 300,000 persons accomplish this? The main reasons are a thriving economy, a high standard of living and education, and the training of surgeons. All Icelandic surgeons receive their training overseas, many at university hospitals in the other Nordic countries, particularly ...
