Holy Grail of geology found: Measuring elevation over geological eras
A Field Museum scientist has developed a novel way to determine land elevation as continents moved around the Earth through geological ages. Knowing how high mountains and plateaus were in the past will help scientists to study how our climate system evolved. "Understanding the past elevation of land surfaces, also known as paleoelevation, has been one of geologys Holy Grails," said Jennifer McElwain, PhD, Associate Curator of Paleobotany at Chicagos Field Museum and sole author of the research to be published in Geologys December issue. "This is the first paleobotanical method that works globally and is independent of long-term climate change.
"The new method will help us to understand the rate at which some of the Earths most important mountains have uplifted," she added. "It will also show how the process of mountain building influenced climatic patterns as well as plant and animal evolution."

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
