Scientists from Fudan University have developed a graphene-integrated silicon nitride microtube resonator via self-rolling nanomembrane technology. By engineering a  lobe structure, they achieved axial mode quantization, creating a potential well that confines light and significantly enhances the quality factor. The device demonstrates high photoresponsivity (2.80 A W^-1) and intrinsic polarization sensitivity, offering a versatile platform for compact, high-performance on-chip photonic-electronic systems.

A research team from the Okinawa Institute of Science and Technology (OIST) has simulated and extended a famous quantum phenomenon , the Aharonov–Bohm effect, using a simple water tank. By sending water waves toward a swirling vortex from opposite directions of the tank, the team observed flat, rotating lines of water that radiate across the whole tank. This classical analogue offers a visually accessible way of studying how the quantum world behaves. 

Researchers have developed a new method to measure the small forces exerted by light with high precision. Using this approach, they discovered a surprising phenomenon in which light can twist tiny objects sideways, in a direction perpendicular to the light's direction of travel.

How can the mild flavor of flaxseed oil be preserved for longer? A research team led by Roman Lang from the Leibniz Institute for Food Systems Biology at the Technical University of Munich has investigated this question. As the team demonstrates in its latest study, natural precursors of bitter-tasting compounds can be gently removed from the oil using bleaching earth (magnesium-aluminum silicate). This results in significantly fewer bitter-tasting compounds formed during storage, and the flaxseed oil remains flavor-stable for longer. The particular advantage: The high content of health-beneficial fatty acids as well as the oil’s typical character are preserved despite the purification process.

Researchers at TU Wien have shown that many 2D materials once considered highly promising are in fact unsuitable for this purpose. When 2D materials are combined with an insulating layer, an extremely thin gap inevitably forms between them, drastically degrading their electronic properties. The good news is that this approach also allows researchers to identify which materials are not affected by this problem—potentially saving the semiconductor industry from investing billions in technologies that are fundamentally limited by the laws of physics.

Backed by approximately 9 million euros from the Helmholtz Initiative and Networking Fund, the campaign brings together nine Helmholtz centers in a collaborative effort that bridges research, industry, government, and civil society. At the heart of this initiative are three “Solution Labs” – real-world demonstration sites where innovative water management approaches are tested and refined. These labs operate across different scales, from entire river basins to urban infrastructures and even microscopic pollutant processes. The Helmholtz-Zentrum Dresden-Rossendorf (HZDR) contributes with two projects: the URBAN-LE Solution Lab in Leipzig and the SOLVE initiative in the Elbe River basin.

Researchers led by Andrew Barnabas Wong at the National University of Singapore have developed a simple, low-cost method to significantly improve the electrochemical conversion of carbon dioxide into valuable fuels and chemicals, offering a potential pathway to reduce reliance on fossil fuels. By coating copper catalysts with nanometre-thin films of biopolymers derived from waste materials such as seafood shells and wood, the team achieved up to 90% selectivity for multicarbon products like ethylene at industrially relevant reaction rates, while also replacing expensive and environmentally harmful PFAS-based materials commonly used in such systems. Reported in Nature Energy, the approach enhances efficiency by concentrating CO₂ at the catalyst surface and suppressing unwanted reactions, demonstrating a scalable route towards greener, more cost-effective production of fuels and chemical feedstocks using renewable electricity.

Sungkyunkwan University announced the publication of a comprehensive report analyzing technological advancements and global research trends in perovskite solar cells (PSCs), which are emerging as a next-generation solar energy technology.

The red coloration of red-leaf lettuce is attributable to anthocyanins. Researchers at University of Tsukuba showed that targeted knockout of genes encoding enzymes involved in anthocyanin biosynthesis, achieved through genome editing, eliminates red pigmentation without causing detectable effects on plant growth. They further demonstrated that this modification increase levels of other flavonoids, including quercetin.
