A research team at the University of Vienna led by physicist Jani Kotakoski demonstrates how the shape of nanopores in hexagonal boron nitride - the electrically insulating counterpart to graphene, also known as "white graphene" - can be precisely controlled at the atomic level. Electron irradiation in ultra-high vacuum creates circular pores, while adding small amounts of oxygen yields triangular pores. The nanopore engineering presented in the journal Nature Communications thus unlocks new applications in filtration, DNA sequencing, catalysis, and quantum technologies.

Researchers have developed an AI-based system that automatically and objectively detects the moment when fish experience loss of equilibrium (LOE) due to temperature stress. The system combines DeepLabCut, a deep-learning AI that captures animal posture from video, with ResNet34, a deep-learning AI-based image-classification technology. Their system is expected to help predict the effects of climate change on fish. The research team was led by Specially Appointed Lecturer Tomoya Nakayama and Yoshiya Matsuo (a master’s student at the time) of the Institute of Transformative Bio-Molecules (WPI-ITbM) at Nagoya University, in collaboration with Associate Professor Tatsuto Hasegawa and Takuya Kato (a master’s student at the time) of the University of Fukui. Their research was published in the journal Scientific Reports on September 10, 2026.

The FAST All Sky HI Survey (FASHI) team has released its second data set (DR2), cataloging 156,411 extragalactic neutral hydrogen (HI) sources over ~19,500 square degrees — nearly half the entire sky. The number of detected sources is nearly four times that of the first data release (DR1) and five times that of the Arecibo ALFALFA survey. With a median sensitivity of 0.57 mJy/beam, FASHI DR2 represents the largest and most sensitive blind HI survey ever conducted, providing a landmark dataset for studies of galaxy evolution, cosmology, and large scale structure in the local Universe.

An efficient few-shot framework was developed for large-scale annotation of light-trapped insect images. MLTIDD integrated Grounding DINO, SAM, and SAHI for multi-scale insect detection, while InsectSSRL exploited massive unlabeled insect images to enhance few-shot classification. MLTIDD achieved 79.6% AP50–95 and 90.8% AR, while InsectSSRL achieved 80.35% classification accuracy using only 5% labeled data. The framework reduced expert annotation time by approximately 80%, enabling efficient large-scale dataset construction.

Researchers at Wuhan University developed a molecular-sieve-assisted confined molten-salt route to grow 2.66 nm Na₂Nb₄O₁₁ single-crystal sheets. Devices made from the material combined sensitive ultraviolet detection with millisecond response and stable cycling, and enabled UV imaging and proof-of-concept two-wavelength physical-layer information encoding.

Researchers from Shenzhen University and collaborating institutions have provided a comprehensive review of viologen-linked covalent organic frameworks (Vio-COFs) as an emerging class of charged and redox-active porous materials. With their unique combination of permanent positive charges, reversible viologen redox chemistry, and well-defined porous frameworks, Vio-COFs offer versatile platforms for modulating electron transfer, ion migration, and host–guest interactions. This review highlights recent developments in the design strategies, structural properties, and functional applications of Vio-COFs, emphasizing their potential in catalysis, energy conversion and storage, environmental remediation, and optoelectronics. Overall, the insights presented in this review pave the way for the rational design and engineering of next-generation multifunctional Vio-COF materials.

Researchers from Soochow University in China have developed a fast vapor-deposition strategy to fabricate twisted vertical heterostructures (TVHs) from two-dimensional organic crystals. By precisely controlling the deposition temperature through adjusting diffusion distance, the yield of vertical epitaxial structures is dramatically increased from below 20% to over 70%. The resulting TVHs exhibit a fixed 45° twist angle between crystal layers, enabling color-tunable interlayer coupling emission that ranges from blue to yellow-green. This work provides a practical approach for kinetic control of vertical heteroepitaxy and lays a material foundation for integrated photonics applications.

This study identified developmental stages and regulatory factors underlying stem quality of rapeseed (Brassica napus L.) under high-density planting. In two cultivars grown at low and high density, gibberellin (GA)-triggered early stem elongation was found to be associated with delayed secondary cell wall deposition and reduced stem mechanical strength under high density. Foliar application of the GA biosynthesis inhibitor uniconazole at the 10–11 leaf stage delayed GA activation and slowed stem elongation, increasing stem mechanical strength and yield.
