Relaxor ferroelectrics have greatly enhanced electrical and mechanical properties that originate in the materials’ domain structure. Knowing how quickly these materials’ properties can change is critical to understanding them. However, scientists have not been able to measure how fast these materials can respond. This study measured this reaction speed using ultrafast electron diffraction at the atomic level to obtain snapshots of the evolving domain structure.

This study highlights significant advancements in intelligent technologies for underground mining in hard rock mines. Key areas of progress include intelligent drilling, blasting, transportation, hoisting, ventilation, and support systems. The integration of deep learning and big data has improved mining efficiency and safety, yet challenges remain. Future efforts must focus on overcoming bottlenecks in these processes to achieve fully automated, unmanned mining operations.

Researchers used municipal solid waste incineration fly ash (MSWI FA), blast furnace slag (BFS), and desulfurization gypsum (DFG) as raw materials to prepare low-carbon, low-cost cementitious materials with no leaching toxicity. This is a first in achieving not only the disposal of hazardous waste but also showing significant potential in the field of backfilling mined-out areas.

Men have higher morbidity and mortality from COVID-19 than women, possibly due to androgen receptor-regulated viral entry protein expression. This led to a clinical trial of androgen deprivation therapy (ADT), which has not shown a significant benefit in the outcomes among hospitalized male COVID-19 patients. The aim of this study was to explore biological explanations for the failure of ADT to mitigate clinical outcomes in men with severe COVID-19 by assessing the role of androgen in regulating viral entry protein expression in the upper and lower respiratory tract.

The review provides a detailed overview of the current understanding of RNA modifications in cancer, emphasizing the potential of targeting these modifications for therapeutic intervention. It also points to the need for further research to uncover the full spectrum of regulatory mechanisms and their implications in cancer biology.
