The Yellowstone "super-volcano" is a little less super—but more active—than previously thought.
Researchers at Washington State University and the Scottish Universities Environmental Research Centre say the biggest Yellowstone eruption, which created the 2 million year old Huckleberry Ridge deposit, was actually two different eruptions at least 6,000 years apart.Their results paint a new picture of a more active volcano than previously thought and can help recalibrate the likelihood of another big eruption in the future. Before the researchers split the one eruption into two, it was the fourth largest known to science.
About WSU: The GeoAnalytical Laboratory housed within the newly formed School of the Environment at Washington State University is a world-class facility for undertaking geochemical research on rocks of all types. The GeoAnalytical Lab, headed by Prof. John Wolff, contains facilities for whole rock analyses and micro-analytical work including a JEOL 8500F field emission (FE) microprobe for analyzing major element chemistry on micron-sized spots, a ThermoFisher Element system for in-situ trace element analyses, and a Finnigan Neptune multi-collector mass spectrometer for precise isotope ratio determinations.
About SUERC: SUERC, the Scottish Universities Environmental Research Centre, is a collaborative research facility operated jointly under a Consortium agreement between the University of Glasgow and Edinburgh University. It hosts five Natural Environment Research Council (NERC) Facilities that are available to UK scientists. SUERC's mission is to perform, stimulate and support high quality basic, applied and strategic research, within the Scottish University community and beyond, in the Earth, Environmental and Biomedical Sciences through development and maintenance of high-end analytical facilities, inter-disciplinary exchange and collaborative interaction. SUERC provides a focus in Scotland for high quality research through its own research programme, by assisting partner to deliver research outputs and through teaching and training, SUERC contributes to the future supply of highly able scientists.

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
