Scientists unlock secrets of cell-surface receptor activation creating opportunities to engineer plant-microbe interactions

In a study combining structural biology, biochemical and genetic approaches, scientists showed that plant cell-surface receptors employ a mechanism for error correction responsible for the control of receptor activation and signaling select bacterial symbionts. This demonstration opens the door to potentially manipulating such receptors’ binding sites in legumes and other organisms in the future. Cell-surface

Scientists probe ferroelectric domains in curved free-standing superlattices

By growing superlattices consisting of ferroelectric and non-ferroelectric transition metal oxides and releasing them from their underlying substrates, researchers explore polarization patterns in curved geometries. Complex transition-metal oxides are often sensitive to strain and may display very different properties if their lattice is compressed or extended. This is especially true of ferroelectric materials, such as

Strong coupling of thin ferromagnet to Manganese Gold compound yields successful antiferromagnetic read-out

Scientists demonstrated a strong coupling of very thin ferromagnetic Permalloy layers to the antiferromagnetic spintronics compound Manganese Gold. This enabled them to apply well-established read-out methods commonly applied to ferromagnets in antiferromagnetic spintronics as well. Up to this point, all commercially available spintronics uses ferromagnets as active elements. However, in principle, antiferromagnetic spintronics hold the

New event-averaging method to map catalyst structure and local gas environment simultaneously enables depiction of transitional active surface structures

One of the key challenges in catalysis research is to understand how catalysts’ structure and function relate to each other. Regardless of the type of catalyst in question, structure and function are dynamic with a strong dependence on the localized reaction conditions such as temperature, pressure, and gas composition just above the catalyst surface. Now,

Scientists detect key structures responsible for coupling process in sugar symporters and decode active sugar transport in plants

Researchers from Aarhus University achieved breakthrough insights about the coupling process that allows active sugar transport in plants aided by MAX IV’s BioMAX beamline. They successfully detected the inward and outward confirmations of the symporter Sugar Transport Protein 10 (STP10) – a protein responsible for monosaccharide transport across cell membranes – at high resolutions (1.8

Zigzag graphene nanoribbons’ surface state hints at spin-polarized channels’ potential practical applications

An international team of researchers confirmed that epitaxial zigzag graphene nanoribbons grown on mesa-structured silicon carbide form protected spin-polarized transport channels at room temperature with very weak spin–orbit interaction. They discovered that while the zigzag graphene nanoribbon monolayer sank almost completely into a silicon carbide facet, its lower edge dissolved and mixed with the silicon

Correlative imaging of a single neuronal cell opens the door to profound multi-perspective sub-cellular examinations

Scientists combined two nano-imaging techniques that stand at opposite ends of the electromagnetic spectrum to demonstrate the benefits of correlative imaging to examine individual neurons from different perspectives. To showcase this, they studied the molecular structures of amyloid proteins and investigated the role metal ions may play in the development of Alzheimer’s Disease at a
