Environmental concerns increasing infectious disease in amphibians, other animals

Posted: 18 Jul 2012 11:36 AM PDT

Climate change, habitat destruction, pollution and invasive species are all involved in the global crisis of amphibian declines and extinctions, researchers suggest in a new analysis, but increasingly these forces are causing actual mortality in the form of infectious disease.

X-rays illuminate the origin of volcanic hotspots

Posted: 18 Jul 2012 10:17 AM PDT

Scientists have recreated the conditions at Earth’s core-mantle boundary 2,900 km beneath the surface. Using X-rays at the European Synchrotron Radiation Facility, they probed tiny rock samples at extreme temperature and pressure showing for the first time that partially molten rock under these conditions is buoyant and should segregate towards the surface. This observation is strong evidence for the theory that volcanic hotspots like the Hawaiian Islands originate from mantle plumes generated at the core-mantle boundary.
