A new study solves a long-standing climate mystery: Why don't the records of oxygen isotopes in cave formations like stalagmites—known as speleothems—from central southern China reflect the well-known 100,000-year cycles of ice ages seen in other global climate records? These speleothem records have long been considered a key indicator of the strength of the Asian summer monsoon, so their failure to show these major climate shifts has puzzled scientists for decades.

A research team led by Prof. ZHANG Jian and Prof. ZHANG Yexin from the Ningbo Institute of Materials Technology and Engineering of the Chinese Academy of Sciences, together with Prof. ZHANG Zhaoliang from the University of Jinan, has developed a novel electrified catalysis strategy for DRM, which they termed electrified DRM (e-DRM).

Since the onset of the Anthropocene, chemical pollution has become a major global threat to biodiversity across all ecosystems.

A new study reveals that global ocean analysis products can effectively replace expensive in-situ sound speed measurements for precise seafloor positioning.

A new dispersed particle gel (DPG) suspension has been developed for high-temperature carbon capture, utilization, and storage (CCUS) applications. This innovative material, described in a recent study published in Engineering, shows enhanced thermal stability and plugging efficiency compared to traditional CO₂-responsive gels. The modified DPG suspension demonstrates significant and irreversible swelling at high temperatures, making it a promising solution for improving profile control in challenging reservoir conditions.

This article presents a novel bi-directional converter based interconnection planning approach for hybrid AC/DC microgrids with high renewable penetration. The study proposes a tri-level planning framework incorporating dynamic converter efficiency and a data-correlated uncertainty set, demonstrating improved cost-efficiency and robustness.

Cardiovascular diseases are a leading health concern in Hong Kong, prompting many to undergo regular heart check-ups for their early detection and management. Echocardiography, a key diagnostic imaging tool, plays a crucial role in assessing heart function, offering non-invasive insights into cardiovascular health and aiding in timely intervention. However, interpreting these ultrasound images manually is challenging due to speckle noise and ambiguous boundaries, requiring significant expertise and time. Consequently, a heart check-up is rarely included in a regular annual body check scheme. 

This article delves into the critical issue of corrosion and material degradation in geological CO₂ storage, highlighting the challenges and potential solutions for maintaining the integrity of storage systems. It underscores the importance of understanding these processes to ensure safe and effective carbon capture and storage.
