Researchers at University College London have developed a new computational model of human color vision that accounts for individual physiological differences, explaining why wide-gamut modern displays often appear inconsistent to different viewers. Published in Optics Express, the study demonstrates how adjusting a display's red, green, and blue primary light spectra can help manufacturers build screens that deliver more consistent, accurate colors across a broader audience.

Garbage left outside starts smelling unpleasant very quickly, especially in warm, humid climates that accelerate food decay. In ACS’ Environmental Science & Technology, researchers report a solar-powered lid insert that fits onto standard wheeled trash bins and helps combat the stench. In tests with real food, the lid insert efficiently breaks down acetic acid, the main culprit released from rotting waste that’s responsible for its odors, and continues working for more than a month. 

Measuring vitamin B₁₂ in food usually means bringing the sample to the laboratory. A new fluorescent sensor could help move part of that process onto something much simpler: a paper strip or cotton swab. A new study published in Biomedical Analysis describes a fluorescence-based strategy for portable vitamin B₁₂ (VB₁₂) detection in food samples. Researchers at Liaocheng University developed boron- and nitrogen-co-doped carbon dots (B, N-CDs) that emit bright blue fluorescence under ultraviolet light but become markedly dimmer when VB₁₂ is present. By transferring this sensing chemistry from a liquid assay onto filter-paper strips and a specially designed cotton-swab sensor, the team created two simple formats intended to make the detection step faster, cheaper, and easier to use outside conventional instrument-heavy workflows.

Whether in drug discovery, environmental analysis or metabolomics: anyone analysing complex biological samples often needs to identify the small molecules they contain. Researchers at Friedrich Schiller University Jena, in collaboration with partners from the Helmholtz Zentrum München and the Technical University of Munich, have developed a method that addresses a problem in analytical Chemistry that has persisted for decades. In the latest issue of the journal »Nature Methods«, the team led by bioinformatician Prof. Dr Sebastian Böcker presents its new tool.

The Karlsruhe Institute of Technology (KIT) has put the HoreKa 2 Supercomputer into operation. The new system will support researchers in their efforts to address complex scientific issues, such as climate, new materials, particle physics, energy, and mobility as well as AI research, more quickly. For this purpose, it combines powerful high-performance computing and modern AI technologies. The total cost of the facility amounts to EUR 17 million.

Researchers at Ritsumeikan University and collaborating institutions have shown that counteranions control the solid-state assembly of paramagnetic thiaporphyrin Cu^II complex cations and thereby tune their magnetic behavior. PCCp⁻ formed a charge-by-charge assembly without significant spin–spin interaction, whereas nonplanar counteranions promoted π-stacked cation dimers exhibiting antiferromagnetic interactions. These findings demonstrate that ion-pairing assembly can control molecular spin arrangements, providing a strategy for designing supramolecular materials with tunable magnetic properties for spintronic applications.

Researchers from the Institute of Industrial Science at The University of Tokyo used advanced instruments to watch small crystals on a scale of about one millionth of a meter as they soaked up chloroform. Parts of these crystals were found to work together to change shape, and some crystals began to move. Understanding these effects could lead to the design of new high-tech devices, such as sensors for pollutants.

Researchers at Tsinghua University have developed silicon valley photonic molecular crystals that preserve topologically protected light transport under strong rotational disorder. Inspired by molecular crystals, the platform utilizes randomly oriented silicon photonic “molecules” to explore how molecular rotation affects the topological properties. Combining theoretical modeling, simulations, and experiments, the team demonstrated robust edge states for random rotation angle ranges within 60 degrees. The findings provide a framework for characterizing disordered topological systems and suggest new opportunities for highly-robust photonic circuits and programmable optical platforms. This work would also inspire analogous studies in condensed-matter, acoustic, and cold-atom platforms.
