Global Tectonic Regionalization for Seismological Data Analysis

A global tectonic regionalization, GTR1, has been constructed for use in seismological studies of aspherical heterogeneity. Three oceanic regions are defined by equal increments in the square root of crustal age (25and lO0-m.y. isochrons), and three continental regions are distinguished according to their generalized tectonic behavior during the Phanerozoic (Precambrian shields and platforms, P...

Francis Crick 1916–2004

In March 1953, 31 years after Howard Carter’s astonishing first glimpse into Tutankhamun's tomb, an even more golden treasure was found. Francis Crick and Jim Watson shared that moment of discovery as they looked, for the first time, into the heart of all living things. They saw the structure of DNA, and their vision became the big bang of modern biology. Francis’ life in research began inauspi...
