Lebanon’s democracy faces severe challenges due to political rivalry between parties. A recent study has revealed that the political communication strategy of Hezbollah—a major party in Lebanon—has significantly evolved during recent years. While the party became increasingly critical of rival parties during national crises and confrontations with Israel, it became more cooperative after diplomatic normalization of Iran–Saudi relationship and expressed more positive view of rivals during electoral campaigns.
Photocatalysis is limited by either the charge supply or the charge transfer process. Identifying the correct rate-limiting step is crucial for optimizing reactions. Researchers from JAIST have developed a novel diagnostic method that uses variations in reaction temperature and light intensity to pinpoint the Onset Intensity for Temperature Dependence, a key bottleneck metric. This approach effectively distinguishes between charge supply- and charge transfer-limited regimes.
Vibrational sum-frequency generation (VSFG) is a nonlinear spectroscopic method widely used to investigate the molecular structure and dynamics of surface systems. However, in far-field observations, the spatial resolution of this method is constrained by the diffraction limit, which restricts its ability to resolve molecular details in inhomogeneous structures smaller than the wavelength of light. To address this limitation, we developed a tip-enhanced VSFG (TE-SFG) spectroscopy system based on scanning tunneling microscopy (STM). Using this system, we detected VSFG signals from molecules adsorbed on a gold substrate under ambient conditions. Phase analysis of the interferometric VSFG spectra provided insights into the molecular orientation. Furthermore, the observed VSFG signals were confirmed to originate from a highly localized region within the gap between the STM tip apex and sample substrate. Thus, this method offers an innovative platform for nonlinear optical nanospectroscopy, enabling the investigation of surface molecular systems beyond the diffraction limit.
An Osaka Metropolitan University team has developed Boccia XR, a rehabilitation program using extended reality technology that can be introduced even in environments with limited space.
This book was published in March 2025 to report the outcomes of Japan’s nationwide project, S-18: Comprehensive Research on the Projection of Climate Change Impacts and the Evaluation of Adaptation, which was conducted over a five-year period from 2020 to early 2025. 1) Introduces research methodologies and results that bridging research and climate change policy development; 2) Integrates research framework using common scenarios for climate and socio-economic changes; 3) Reveals interaction among global warming level, social changes and impacts, and effectiveness of countermeasures; 4) This book is open access, which means that you have free and unlimited access;
What caused the extinction of the dinosaurs? The first thing that might come to mind is a meteorite crashing into the Earth. Assistant Professor Honami Sato, a geology researcher at the Faculty of Science, searches for traces of celestial impacts in geological strata to decipher the mechanisms of environmental changes on the planet. We spoke with Sato about her methods of stratigraphic surveying and her fascination with geology.
Plants produce organic compounds from surrounding inorganic matter, and in turn, animals—including humans—live off the organic matter that these plants create. We spoke to Professor Akiko Maruyama from the Faculty of Agriculture to learn more about the essential nutrients required by plants, which support life on Earth, and her fascination with plant science research.
We've all had the experience of staying up late and not being able to wake up the next morning. This difficulty arises due to a shift in what's known as our biological clock, which is the central theme of Professor Hiroshi Ito's research at Kyushu University's Faculty of Design. We spoke with Ito to explore the advantages of cross-disciplinary studies and to discover how he uses his expertise in robotics, artificial intelligence (AI), and engineering to understand the true nature of the biological clock.
