Dr. Hye Jung Chang and Dr. Kyung Joong Yoon (Director) of the Hydrogen Energy Materials Research Center at the Korea Institute of Science and Technology (KIST) have announced that they have elucidated the mechanism of the initial degradation phenomenon that triggers the performance drop of high-temperature solid oxide electrolysis cell systems, using advanced transmission electron microscopy.

In the aesthetic-concerning maxillary alveolar basal bone, which requires quantifying a total of 9 indices from length and width dimensional, this study collected a total of 4,000 cone-beam computed tomography (CBCT) sagittal images, and developed a deep learning model composed of a backbone and multiple regression heads with fully shared parameters to intelligently predict these quantitative metrics. This work validates that the demographic parity strategy enables the AI algorithm with greater model generalization ability, even for the highly variable traits, which benefits for the appearance-concerning maxillofacial surgery.

In a paper published in SCIENCE CHINA Chemistry, Mn-doped-Cu catalyst was synthesized and employed for electrochemical NO₃^--to-NH₃ conversion. the Mn dopant enhanced the kinetic rate of NO₂^--to-NH₃ and induced a distinct configuration of *NO. This alteration decreased the energy barrier of *NO-to-*NOH, consequently promoting the conversion of NO₃^--to-NH₃.

Estimating composite material properties can be computationally expensive and time-consuming. Researchers propose a Reduced Basis Homogenization Method (RBHM) to enhance homogenization based on a Finite Element Method (FEM). This RBHM significantly improves computational efficiency while maintaining high accuracy.

The first depression health economic modelling study, led by Professor Shirley Li Xue, from the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), revealed that Hong Kong will face a significant and ongoing burden of depression from 2023 to 2032. While fewer than 20% of the cases are expected to develop treatment-resistant depression (TRD) or related comorbidities, this group is expected to account for close to half of depression-related medical costs in the city. 

This study argues that ecolinguistics should consider language as a fundamental human activity that shapes technologically mediated environments. It emphasizes the role of languaging in skill development and expertise acquisition, particularly in second language learning. By integrating languaging, statistical learning, and skillful action, technology can foster diverse coordinated activities. Therefore, the authors advocate for creating technology-rich environments that enable individuals to transform themselves through second language acquisition and the development of new skills and expertise.

The trace anomaly is one of the quantities that encodes the energy and momentum of particles built from quarks. Scientists believe the trace anomaly is crucial for keeping quarks bonded in subatomic particles. In this study, scientists calculated the trace anomaly for nucleons and pions. The calculations show that in the pion, the mass distribution is similar to the charge distribution of the neutron and in the nucleon, the mass distribution is similar to the charge distribution of the proton.

Childbirth, largely a physiologic process, occurs 140 million times per year. Yet, it comes with risks; one mother dies every two minutes worldwide. The risks also extend to the newborn; in 2020, 2.4 million newborns died—25% on the first day of life. The optimal management of labor and prevention of complications require up-to-date information. The American Journal of Obstetrics & Gynecology (AJOG), the premier journal in the discipline, has published a supplement devoted to labor and delivery at term. The content addresses important issues in intrapartum care and advocates for respectful and safe maternity care for all.  

In a feature article published in SCIENCE CHINA Chemistry, Ming Gong’s group summarized their latest progresses in exploring the effects of ions on electrocatalytic reactions, outlined the current challenges and opportunities in the study of ion effects, and provided insights into future research directions.
