Our study uses Hong Kong as a case study to elucidate migration intentions in the context of political polarization and increasing authoritarianism. We investigate how individuals facing the same political conditions exhibit varying inclinations to migrate. Our analysis is based on dyadic data from a representative household survey involving 1003 married couples. The findings reveal that spousal pro‐democratic attitudes and affective polarization are associated with stronger migration intentions, with significant implications for predicting migration patterns. Moreover, the study highlights the significance of the interactive role between individuals’ and the spouses’ political attitudes in shaping migration intentions.

Taiwan's New Public Health Preventive Medicine Strategy Achieves Success After 10 Years

The equatorial Pacific plays a crucial role in regulating tropical cloud formation and regional weather extremes, earning it the nickname “the pacemaker of global warming.” Though its impact may seem subtle, this oceanic region has been a silent hero, slowing the pace of global warming. Now, climate scientists are on a quest to discover whether this protective mechanism will continue to pulsate in our favor.

How multiple DNA binding proteins compete for the DNA substrate leads to different biochemical outcomes. Using single-molecule experiments, this work demonstrates that the regulatory protein Mei5-Sae3 complex stabilizes Dmc1 recombinases on RPA-coated DNA, leading to efficient RPA displacement and Dmc1 assembly, which in turn stimulates recombination progression.

Altermagnetism (AM) is an emerging type of magnetism, combining advantages of both antiferromagnetism (AFM) and ferromagnetism (FM), with no net magnetization and spin-splitting Fermi surfaces. It is ideal material for spintronic applications. In our work, we studied the inverse altermagnetic spin-splitting effect (IASSE) in epitaxial RuO2 film capped by ferromagnetic insulator YIG layer. By injecting a spin current from YIG into RuO2, we observed a significant anisotropic spin to charge conversion with spin index parallel or perpendicular to the Néel vector directions, revealing the inverse altermagnetic spin-splitting effect (IASSE) in RuO2. Furthermore, we verify the ordering of the Néel vector along the [001] direction from magnetization measurements. Our study provides critical insights in the understanding of altermagnetism.

Ceramic-rich composite electrolytes: An overview of the paradigm shift from high-performance lithium metal batteries to solid-state electrolytes

Dr. Chung-Che Wu, a Ph.D. graduate from the Department of Geosciences, National Taiwan University (NTU), along with Prof. Chuan-Chou Shen, the National Chair Professor, collaborating with an international research team from the Swiss Federal Institute of Technology (ETH), Switzerland, published a cutting-edge laser-ablation uranium-thorium dating (LA U-Th dating) technology in the prestigious journal "Analytical Chemistry" on August 6th (1) and was selected as one of the cover articles (Figure 1). This breakthrough technology improved LA U-Th dating limits to within tens of thousands of years, with the youngest geological samples dated to only a thousand years, making it the most advanced analytical technique internationally.

This study reports the first attempt to characterize the quality, defects, and strain of as-grown monolayer transition metal dichalcogenide (IMDC)-based 2D materials through exciton anisotropy. A standard ellipsometric parameter (Ψ) to observe anisotropic exciton behavior in monolayer 2D materials is used. According to the strong exciton effect from phonon-electron coupling processes, the change in the exciton in the Van Hove singularity is sensitive to lattice distortions such as defects and strain. In comparison with Raman spectroscopy, the variations in exciton anisotropy in Ψ are more sensitive for detecting slight changes in the quality and strain of monolayer MDC films. Moreover, the optical power requirement for TMDC characterization through exciton anisotropy in Ψ is ~10-5 mW·cm-2, which is significantly less than that of Raman spectroscopy (~106 mW·cm-2). The standard deviation of the signals varies with strain (defects) in Raman spectra and exciton anisotropies in Ψ are 0.700 (0.795) and 0.033 (0.073), indicating that exciton anisotropy is more sensitive to slight changes in the quality of monolayer TMDC films.

14-3-3η: A protein that helps fight RNA viruses but can also be manipulated by them. New research reveals its complex role in the immune response

Professor Hsiao-Wei Yuan from the School of Forestry and Resource Conservation at National Taiwan University (NTU) has been leading a team since 2003 dedicated to the research and protection of the endangered Chinese Crested Tern, also known as the 'Mythical Bird,' with only fewer than 100 individuals remaining. Their efforts have drawn international attention to this species, leading to conservation efforts and showcasing Taiwan's efforts in biodiversity conservation and key research achievements. After 20 years of conservation efforts, the population of Chinese Crested Terns has increased to approximately 150 individuals.

By putting theory into practice, Prof. Pi-Tai Chou’s research team has repeatedly broken the world record for NIR organic luminophores, overcoming the energy gap law. In 2017, we developed a material with an external quantum efficiency (EQE) of 24% at 740nm, followed by a molecule with an EQE of 10% at 800nm in 2018. In 2020 and 2022, through deuterium substitution, we successfully developed unprecedented OLEDs with an EQE of 4% at 1000nm. However, developing new cutting-edge materials is challenging. Alternatively, in terms of device engineering, we have been continuously exploring new techniques to further enhance efficiency using existing materials. This paper, published in Nature Communications (2024, 15 (1), 4664), marks the first time internationally that transfer technology has been successfully utilized to break the energy gap law through energy transfer, achieving record-breaking efficiency.

Over millions of years, Earth has experienced cycles of ice ages and warm periods. Today, we find ourselves in a warm period heavily influenced by human activities. As greenhouse gas levels in the atmosphere rise, global warming intensifies, causing ice sheets to melt rapidly, sea levels to rise, and posing severe threats to global ecosystems and human societies. Understanding the mechanisms behind these warming periods by studying past extreme warm periods is a crucial task for modern scientists.

Pathogens hijack host cell functions by expressing or secreting effector proteins, creating environments conducive to their survival and reproduction. These pathogenic microorganisms—including eukaryotic parasites, prokaryotic bacteria, and viruses—express effector proteins that function as their "ammunition depot". These proteins are crucial for pathogen survival and dissemination, enhancing the efficiency of invasion, suppressing the host's immune system, or initiating pathogen replication. For instance, viruses may interfere with host signaling pathways, pushing cells into states that favor viral replication. Similarly, certain bacteria secrete toxins that disrupt the host cell cytoskeleton, facilitating pathogen invasion and spread. Additionally, pathogens can evade immune surveillance by suppressing the host's immune response, thereby increasing the likelihood of a successful infection.
