This study extends Thouless pumping from periodic to quasi-periodic driving, uncovering the intrinsic link between topological transport and the irrational frequency ratio of the lattice modulation. The findings broaden the applicability of Thouless pumping in topological transport.

A perspective published by researchers at the University of Science and Technology Beijing discusses research by Stoddart et al. in Nature Chemistry that demonstrates that engineered supramolecular crystals can optimize hydrogen storage performance.

New computer simulations that model every atom of a protein as it folds into its final three-dimensional form support the existence of a recently identified type of protein misfolding.

Scientists from the Institute of Oceanology of the Chinese Academy of Sciences have discovered a massive hydrogen-rich hydrothermal system beneath the western Pacific seafloor, offering a new glimpse into deep-sea serpentinization—a process in which iron- and magnesium-rich rocks chemically react with water to form serpentine minerals and release hydrogen.

Organic molecules that combine efficient light emission for displays and strong light absorption for bioimaging are difficult to design due to conflicting structural requirements. Researchers from Japan addressed this challenge by developing CzTRZCN, a single molecule that switches structure depending on light interaction, enabling both two-photon absorption and thermally activated delayed fluorescence. These dual functions are useful in OLEDs and biomedical imaging, paving the way for versatile organic materials in electronics, medicine, and life sciences.

How can quantum technologies be developed responsibly? In the journal Science, researchers from the Technical University of Munich (TUM), the University of Cambridge, Harvard University and Stanford University argue that international standards should be established before laws are enacted. Prof. Urs Gasser explains why the authors propose a quality management system for quantum technologies, how standards create trust and where even competing countries such as China and the US can cooperate.
