Underwater wireless power transfer is emerging as a key technology for enabling long-duration, maintenance-free operation of autonomous underwater vehicles (AUVs). This review provides the most comprehensive overview to date of magnetic-coupling-based underwater wireless charging, addressing challenges such as eddy current losses in seawater, misalignment caused by ocean dynamics, and the growing need for simultaneous transfer of power and data. By comparing transmitter–receiver coil structures, compensation networks, and control strategies, the research identifies design pathways that significantly enhance efficiency, stability, and tolerance to dynamic marine conditions. The work also highlights emerging simultaneous wireless power and data transfer (SWPDT) methods that could reshape the future of marine sensing and robotic operations.

Machine learning (ML) is rapidly emerging as a powerful tool to improve the safety, reliability, and long-term performance of marine structures exposed to harsh ocean environments. This study presents a comprehensive review of ML and deep learning algorithms applied to marine engineering, highlighting how they enhance structural design, construction efficiency, and real-time maintenance. The work introduces a novel modeling framework that integrates mechanical principles with data-driven algorithms, improving interpretability and prediction accuracy. It also outlines key challenges such as data scarcity, environmental uncertainty, and model transparency, offering guidance for future research. The review provides valuable insights for structural engineers seeking to adopt ML technologies for next-generation ocean infrastructure.

Hair loss and graying, the earliest visible hallmarks of skin aging, result from the functional decline of hair follicle stem cells (HFSCs) and their niche. Dr. Zhao and colleagues conducted a comprehensive analysis of human scalp samples using single-cell RNA sequencing (11 samples, 57,181 cells in total) and spatial transcriptomics (1 sample) to detail the mechanisms involved. The study confirmed the transitional stages of three mitotic keratinocyte subtypes. Comparison of middle-aged and young scalps revealed three key age-associated changes: activated AP-1 transcription factor complex in keratinocytes; up-regulated DCT gene in melanocytes; and a dramatic decrease in BMP and non-canonical WNT (ncWNT) signaling within the critical dermal papilla-keratinocyte crosstalk. This breakdown of essential inter-cellular communication and activation of stress signals provides valuable, cell-resolved insights into hair follicle aging, supporting the development of future regenerative therapies targeting these pathways.

Researchers from Southeast University have developed a compact, dual-band, dual-polarized phased array for B5G/6G millimeter-wave communication. The array integrates four independent beamforming systems on a single printed circuit board, supporting concurrent operations at 28 GHz and 38 GHz. It features scalable architecture, broad bandwidth, and high spectral efficiency, making it ideal for future high-speed wireless applications.

On November 8, 2025, the Faculty of Education at East China Normal University hosted a grand ceremony to present the second Global Award for Innovation in Education Research Methods. Five distinguished scholars—Ruth Hayhoe, Stephen Raudenbush, Manabu Sato, Shanmai Wang, and Rupert Wegerif—from Canada, the United States, Japan, China, and the United Kingdom were honored with this year’s award.

The ability to generate and detect ultrashort light pulses in the ultraviolet UV-C range (100-280 nm) is crucial for many applications. This work demonstrates a UV-C source-sensor platform that combines nonlinear optical crystals for the generation of femtosecond UV-C laser pulses with photodetectors based on atomically-thin semiconductors. The platform has potential for different technologies, from broad-band imaging to spectroscopy on femtosecond timescales. As a proof of concept, the source-sensor is used to demonstrate free-space communication.

“By correcting initial cloud fields with real-time satellite data, we essentially gave the forecast system a ‘live cloud map’. This is not only a technical breakthrough but also provides a practical tool for grid scheduling and China’s dual-carbon strategy.”“By correcting initial cloud fields with real-time satellite data, we essentially gave the forecast system a ‘live cloud map’.
