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."

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
