Osaka Metropolitan University researchers have succeeded in generating high-quality feline embryonic stem cells using sperm and eggs from testes and ovaries discarded during sterilization surgery.

The study introduces a breakthrough method for Knowledge Graph Completion that utilizes higher-order neighbor subgraphs to effectively address the challenge of high sparsity in Knowledge Graphs.

Recent advances in astronomical observations have found a significant number of extrasolar planets that can sustain surface water, and the search for extraterrestrial life on such planets is gaining momentum. A team of astrobiologists from Astrobiology Center, National Institute for Basic Biology, and SOKENDAI have proposed a novel approach for detecting life on ocean planets. By conducting laboratory measurements and satellite remote sensing analyses, they have demonstrated that the reflectance spectrum of floating vegetation could serve as a promising biosignature. Seasonal variations in floating vegetation may provide a particularly effective means for remote detection.

The results of this research will be published in the journal Astrobiology on February 24, 2025.

Researchers from the Technical University of Denmark (DTU) have made a groundbreaking advancement in terahertz (THz) detection, enabling ultra-broadband and scanning-free detection of THz waveforms. This innovation paves the way for faster and more efficient analysis of high-energy, low-repetition-rate THz pulses, with broad applications in material science and extreme nonlinear spectroscopy.

Novel protein cage system can control and visualize orientational changes in aromatic side chains upon ligand binding, as reported by researchers at Institute of Science Tokyo. By inducing coordinated molecular changes, this approach enables precise control over protein dynamics while also enhancing fluorescence properties. Their breakthrough could lead to applications in biomolecular robotics, drug delivery, and advancing the development of responsive biomaterials.

In a recent issue of the International Journal of Extreme Manufacturing, Hongbo Lan and his team from Qingdao University of Technology published a review article on multi-nozzle electrohydrodynamic (EHD) printing.

Multi-nozzle EHD printing is poised to become the most promising technology for the industrial production of micro/nano-scale devices on flexible substrates. Their work provides a comprehensive summary of nearly 20 years of research on this technology, establishing a solid foundation for the industrial fabrication of flexible nanodevices.

Recently, a joint research team from Hangzhou Institute of Technology of Xidian University, Humboldt University and the Max Born Institute announced a breakthrough in fabricating high-precision tunable nanogratings through femtosecond laser bursts-induced oxidation of amorphous silicon films. This achievement overcomes the limitations of conventional processes and provides a pioneering solution for high-efficiency, high-quality, and controllable self-organized micro/nanofabrication driven by femtosecond lasers. The related findings, entitled‘Burst Laser-Driven Plasmonic Photochemical Nanolithography of Silicon with Active Structural Modulation’, were recently published in Ultrafast Science, a subsidiary journal of Science.
