Satellite images help assess effective use of cover crops in the Netherlands

Researchers from the University of Twente’s Faculty of Geo-Information Science and Earth Observation (ITC) have used satellite images to assess the effective use of cover crops in the Dutch province of Overijssel. The study focuses on analysing satellite images from 2017 and 2018 and the results have now been published in the International Journal of Applied Earth Observation and Geoinformation.

The nature of glass-forming liquids clarified

Glass is such a common material that you probably don’t think about it much. It may surprise you to learn that researchers today still don’t understand how glass forms. Figuring this out is important for glass industries and many other surprising applications of glasses.

Scientists discover new forms of feldspars

In high-pressure experiments, scientists have discovered new forms of the common mineral feldspar. At moderate temperatures, these hitherto unknown variants are stable at pressures of Earth’s upper mantle, where common feldspar normally cannot exist. The discovery could change the view at cold subducting plates and the interpretation of seismologic signatures, as the team around DESY scientist Anna Pakhomova and Leonid Dubrovinsky from Bayerisches Geoinstitut in Bayreuth report in the journal Nature Communications.

Probing the secret forces of pericytes

Leiden researchers found a way to measure the tiny forces exerted by pericytes, one of the most elusive, hard to research cell types, which occur in tiny blood vessels. Building on this fundamental science, researchers may eventually find treatments for medical conditions like ischaemia.

New type of coupled electronic-structural waves discovered in magnetite

An international team of scientists uncovered exotic quantum properties hidden in magnetite, the oldest magnetic material known to mankind. The study reveals the existence of low-energy waves that indicate the important role of electronic interactions with the crystal lattice. This is another step toward fully understanding the metal-insulator phase transition mechanism in magnetite, and in particular, to learn about the dynamical properties and critical behavior of this material in the vicinity of the transition temperature.

Scientists solve half-century-old magnesium dimer mystery

Magnesium dimer (Mg2) is a fragile molecule consisting of two weakly interacting atoms held together by the laws of quantum mechanics. It has recently emerged as a potential probe for understanding fundamental phenomena at the intersection of chemistry and ultracold physics, but its use has been thwarted by a half-century-old enigma—five high-lying vibrational states that hold the key to understanding how the magnesium atoms interact but have eluded detection for 50 years.

New integrated device for nanometer-scale sensing

Researchers at Eindhoven University of Technology have developed a new, integrated optical sensor that provides increased resolution in measurements and paves the way for fully integrated and compact optical sensors including lasers and detectors for on-chip sensing platforms. Such sensors could play a pivotal role in accurate displacement and force measurements at the nanoscale, which is crucial for microchip and nanodevice design and evaluation. This research has been published in Nature Communications.
