The Korea Research Institute of Standards and Science (KRISS, President Dr. Ho Seong Lee) has re-measured a key transition frequency of the strontium (Sr) atom for the first time in 88 years since 1938, using a photonic grating chip, and has established a new absolute frequency value with a measurement uncertainty reduced by more than 50 times. By securing an accurate reference value needed for next-generation quantum technologies ahead of time, this achievement is expected to greatly contribute to the precise control and miniaturization of quantum devices, including atomic clocks and neutral-atom quantum computers.

Factors such as sunlight and stage-specific nutrient application determine crop success in urban agriculture, far beyond fixed recipes or miracle solutions. This is demonstrated by an eight-year study conducted by the Institute of Environmental Science and Technology at the Universitat Autònoma de Barcelona (ICTA-UAB), Spain, in its build-integrated rooftop greenhouse, thermally connected to the facility itself, and located within the university campus.

For museums using digital content, creating experiences that build emotional connections with visitors is key to making digital cultural experiences more engaging, finds a study from Science Tokyo. A survey of 266 visitors at the Ryushi Memorial Museum revealed that immersive digital exhibits helped visitors connect with personal memories, historical stories, and cultural heritage. The findings suggest that museums can increase engagement by designing digital experiences around local stories, memories, and cultural identity.

Wireless charging has already transformed how people power phones, wearables and even electric vehicles. The next leap is advancing wireless technologies to not merely deliver electrical energy, but to enable direct non-electrical outputs, such as optical, thermal and mechanical energy, directly according to actual needs, building an energy delivery network as flexible and efficient as the internet. To drive this transformation, researchers at The Hong Kong Polytechnic University (PolyU) have conducted a groundbreaking study that sets out a technical roadmap for “wireless energy internet”, guiding the industry from “wireless power transfer” toward direct “wireless energy conversion”.

In today's digital world, everything from medical images and financial records to personal photos and secure communications depends on encryption systems that can protect sensitive information. But real-world technologies rarely operate under perfect conditions. Measurements can be imprecise, hardware introduces small errors, and communication channels are often affected by noise.

Four decades after the 1986 nuclear disaster, researchers at Leibniz University Hannover and the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) examined six tiny, highly radioactive fragments that were released from the destroyed reactor in Ukraine in the wake of the incident. Analyses show that these “hot particles” are far more stable than had previously been assumed. The findings could allow for more precise assessments of the health risks posed by such radioactive particles (DOI: 10.1016/j.jhazmat.2026.141533).

Researchers at Universidad Carlos III de Madrid (UC3M) have designed and tested a new type of modular tire aimed at making it smarter and more sustainable. As part of the ECOTIRE project, they have developed a removable silicone tread that can significantly increase durability, reduce abrasive wear, and mitigate pollution caused by rubber waste.

Deep learning overcomes the limitations of traditional methods in behavioral prediction and neural decoding—such as handcrafted features, linear models, and physical priors—and through high-dimensional nonlinear modeling, multimodal fusion, and interpretable learning, significantly improves the accuracy of action and trajectory prediction as well as the mechanistic interpretability of neuro-behavioral decoding, driving the field from black-box prediction toward a mechanism-driven scientific discovery platform.
