Scientists in China have developed a compact quasi-BIC laser that emits an ultrahigh-purity linearly polarized light. Using dispersion-assisted polarization engineering, the device achieves a polarization extinction ratio of ~300:1 in a 20 by 20 lattice while maintaining single-mode operation and good beam quality.

In a recent Finnish study, more screen time since childhood was associated with better cognitive processing in adolescence. According to one of the researchers, we should not regard screen time solely as harmful. The most important thing is to find a balance between physical activity and screen time that promotes active thinking.

The cement industry accounts for five to eight per cent of global CO₂ emissions, thereby contributing significantly to climate change.   

Researchers at ETH Zurich have shown that the climate impact of cement production could be reduced through direct integration with direct air capture technology by 78 per cent by 2050. 

The technology utilises existing processes and raw materials from cement manufacturing and could be relatively easily integrated into cement production. 

For the first time, researchers have developed a technology that could enable 6G antennas to be mass-produced on wafers in much the same way as semiconductor devices.

Artificial intelligence (AI) is moving beyond screens into cars, drones, service robots and collaborative machines that can perceive, reason and act. 

 A research team led by Dr. Kang Daehyun at the Center for Climate and Carbon Cycle Research of the Korea Institute of Science and Technology (KIST; President Oh Sang-rok) announced that it has developed KIST-Ocean, an AI-based global ocean prediction model, to overcome these limitations. This achievement is the result of the KIST Climate and Environment Research Institute, which was established to predict and respond to climate change through science and technology. It is significant in that it has successfully integrated AI technology into the field of long-term ocean and climate forecasting-which requires vast amounts of observational data and physics-based analysis capabilities-thereby achieving both high accuracy and computational efficiency.

For the first time, researchers have demonstrated that the “ability to forget” can serve as a new computational function for artificial intelligence.

Researchers from the RIKEN Center for Sustainable Resource Science (CSRS) and RIKEN Pioneering Research Institute (PRI) in Japan together with collaborators from the University of Münster, Germany, have developed a new hydrogel that offers significant advantages over others currently on the market in the field of biomaterials. The new hydrogel has a highly organized structure made from nanofibers that contain tiny water channels. The molecules within each nanofiber all point in the same direction, creating an electrical polarization along the fiber. This means that in addition to being strong and flexible, the new gel could be used to transport ions, generate electrical signals when squeezed, or have other advanced interactions with biological tissues.
