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.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
