proteins, KaiA, KaiB, and KaiC assemble to form the KaiABC complex. Cryogenic electron microscopy studies can identify most of the structure of this complex, but the KaiA protomers seem to be a bit too shy ... despite large fluctuations in the KaiA N-terminal domains, their preferential positionings mask the hydrophobic surface of the KaiA ...

alone. A complete hydrogen-bond network could be observed between the protein and its ligand. A low-barrier hydrogen bond was also identified ‑ a special type of strong hydrogen bond which plays a role in ... Nature Communications. Antibiotic resistance is a rapidly increasing global threat to human health. The World Health Organization has ...

achieved by a number of ways that grows exponentially with the number of tetrahedra. In this context, the possibility of a quantum variant of spin ice has aroused a lot of attention. Such a state of matter ... Credit: Nicolas Gauthier May 2020 Spin ice is a recently discovered state of matter, made of a macroscopic landscape of degenerate magnetic ...

graphite. Typically, diffusion, the speed of a particle’s movement on a surface, is a thermally activated process. The higher the temperature, the faster a particle is able to move. At lower temperatures ... movement of a liquid, and there was very little change in its diffusion rate from high to low temperatures, compared to the sample and other ...

describe the internal structure of a magnetic nanoparticle using a simple, static model. According to this model, magnetic nanoparticles are composed of a magnetic core and a surface that is not – or only slightly ... nanoparticles consist of a magnetic material containing, for example, iron, nickel, or cobalt. If the particles are small enough, ...

mechanical workshop with a wire spark erosion machine. Anode wires are inserted along the centre of the cathode trenches with a precision of 50 micrometres, using a metrology system based on a numerical microscope ... anode wires are run through the cathode trenches at a pitch of 2.5 mm using ceramic combs (right) In order to dispose of a spare ...

layer by layer, a process that often requires multiple steps. A team of our scientists at the Institut Laue–Langevin (ILL) and the Technical University of Berlin (TUB) has developed a one-step procedure ... cost-effective. First, two components are mixed together – a polysaccharide, simple chains of sugar molecules bonded together, and a fatty ...

resulted in the proposal of a molecular mechanism by which transthyretin forms amyloid fibrils through a parallel equilibrium of partially unfolded protein forms. Transthyretin has a complex hierarchical structure ... folded, functional TTR towards amyloid fibrilisation. A new neutron method Additionally, this study has emphasised the potential ...

improved accuracy is rejecting the hypothesis of a 4 th neutrino in a large fraction of the domain predicted from the reactor neutrino anomaly. Profiting from a good control of the detector response, STEREO ... neutrinos has thus entered a high precision era… revealing new anomalies when comparing to expectations. The goal of the STEREO experiment ...

der University (FAU) Erlangen-Nürnberg have taken a major stride towards the construction of a GaAs-based backscattering spectrometer. The result is a drop in energy resolution to several tens of nano-eV ... has convinced them that a full-scale spectrometer could now be built in a straightforward way providing energy resolution in the order of 50 ...
