Reports - June 2005

Comment on the Talking Points in EMBO reports, June 2007.

Frank Gannon’s introduction to the Talking Points about the use of animals in scientific research (Gannon, 2007) underestimated the burgeoning field of animal replacement techniques. Although it is clearly important to be aware of the philosophical arguments against animal research, it is also vital to discuss the scientific issues that surround the debate. Non-animal research methods have enor...

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...
