Subduction-related volcanism in the northern part of the North Island of New Zealand shifted abruptly during the late Pliocene. This study focuses on the transition, in time and space, from the NNW-oriented Miocene–Pliocene Coromandel Volcanic Zone to the northeast-oriented active Taupo Volcanic Zone. The volcanic rocks marking this transition are exposed in the Tauranga Basin and adjacent Kaim...

A biogeographic regionalisation of the Andean region is proposed as a hierarchical classification of sub-regions, provinces, sub-provinces and districts. It is based on biogeographic analyses of terrestrial plant and animal taxa, and seeks to provide universality, objectivity and stability. The Andean region is currently comprised of the Central Chilean, Subantarctic and Patagonian sub-regions ...

Nicholas of Cusa (NC) (1401-1464) is one of the most prominent neo-platonic philosophers of the Renaissance. Son of a rich merchant, he studied liberal arts and canon law in Heidelberg (1416), Padua (1417-1423) and Cologne (1425-1426). His time in Padua let him breathe the free air of Italian quattrocento. There he first met some of his later friends who would become influential men of Church, ...

Seismic waves that traverse Earth's inner core along north-south paths produce unusually broad pulse shapes at long periods (compared with waves along east-west paths) and reflections from below the inner core boundary at short periods. The observations provide compelling evidence for a seismic velocity discontinuity along north-south paths about 200 kilometers below the inner core boundary sep...

The definition of a secured zone is presented, updating RFC 2535. The new definition has consequences that alter the interpretation of the NXT record, obsolete NULL keys, and the designation of "experimentally secure."

Here's how it would work. You would be asked, in a computerized exhibit, to choose your favorite actor or a character in a specific Shakespearean scene. Then, a filmed image of the character or actor you chose would appear on a large wall screen and begin addressing his or her lines directly to you. When your turn to speak comes, all you would then do is to read out the lines scrolling by at th...

Adult subventricular zone neurogenesis is an important process in most mammals. However, whether it persists in humans is highly debated. Recent work by Sanai and colleagues provides a major step in settling this debate. Using histological approaches, they demonstrated an active subventricular zone with limited neurogenesis in humans as well as discovered a new migratory route.
