Researchers reveal a new chemical reaction of nitric oxide and glycine to produce nitrogen gas at room temperature
Denitrification is essential to remove toxic nitric oxide from industrial emissions and polluted water. So far, the industrial process has involved high temperatures. Professor Kitagishi’s group accidentally stumbled upon a new chemical mechanism of denitrification at room temperature and in aqueous solution. They report hemoCD-I/P supramolecules that bind nitric oxide and release nitrogen when in acidic glycine-containing solution. This pioneering finding will aid industrial denitrification and accelerate efforts to protect the environment.

Professor Seiko Mimaki from our Graduate School of Global Studies is actively participating in ValEUs, an international research network focusing on challenges related to EU foreign policy and its core values. Led by Viadrina European University in Germany, the network brings together 20 research institutions from 17 countries to conduct interdisciplinary research and education, aiming to provide policy recommendations for both politics and civil society.
In October 2025, the annual ValEUs conference was held in Zagreb, Croatia, where lively discussions addressed the consistency and effectiveness of EU foreign policy under tense geopolitical conditions. Key topics included how the EU is perceived as a “normative power” in the international arena and the internal challenges to fundamental European values. The outcomes will soon be published as an interdisciplinary review, coordinated by Professor Mimaki.
ValEUs also organizes a wide range of activities, including policy brief workshops, civil society debates, “EU Talks” with students and experts, online courses (MOOCs), podcasts, and youth-led policy proposals. These initiatives tackle pressing issues such as strengthening democracy, EU enlargement, and migration, engaging both academic and civic perspectives.

Professor Ken’ichi Ikeda from the Faculty of Social Studies explains that happiness is shaped not only by perceived societal risk but also by inequality in happiness levels. Analyzing data from 32 countries in the World Values Survey, the study finds that when societal risk rises, overall well-being declines sharply, with more people clustering at the lower end of the happiness scale. These insights shed light on why some societies remain strong while others struggle when facing uncertainty.

Title: Interaction effects of societal risk perception and social comparison on subjective well-being
Caption: The figure illustrates how predicted probabilities of reporting life satisfaction levels 7–10 vary across low (−1 SD), average, and high (+1 SD) perceived national/societal risk. Panel 1a shows results stratified by upward social comparison (Iu0), while Panel 1b shows results stratified by downward comparison (Id0). Error bars represent 95% confidence intervals. Both forms of social comparison exert a stronger influence when perceived societal risk is high; and increases in risk generate steeper declines in predicted SWB in strong upward comparison, while keeping SWB level in strong downward comparison, indicating asymmetric psychological effects.

On October 29 and 30, 2025, a research exchange event titled Doshisha Week 2025 was held at the University of Tübingen in Germany. Doshisha Week is an annual research exchange event jointly organized by Doshisha University and the University of Tübingen, hosted by the Doshisha University EU Campus. It is held every year at the University of Tübingen to promote academic collaboration and mutual understanding between the two institutions.
This year’s event was integrated with the overseas activities of doctoral students supported by the SPRING program—Support Project for Pioneering Research Initiated by Next Generation in Doshisha University Doctoral Course. Six SPRING students from Doshisha university participated and presented their research:
Junji ADACHI (Graduate School of Culture and Information Science, D1)
Maiko OKAMURA (Graduate School of Life and Medical Sciences, D1)
Yutaka KOBAYASHI (Graduate School of Life and Medical Sciences, D2)
Wenjing GUO (Graduate School of Studies, D3)
Nehal KHAN (Graduate School of Global Studies, D3)
Maksym YAROSHENKO (Graduate School of Global Studies, D3)
In addition to the SPRING student presentations, six doctoral students from the University of Tübingen, whose research fields closely align with those of the SPRING participants, also gave presentations. They were followed by engaging discussions with participants and local researchers, further enriching the academic exchange. This mutual interaction fostered deeper understanding and collaboration among the participants. Beyond the presentations and discussions, participants also visited related laboratories at the University of Tübingen, further strengthening the potential for future research collaboration between the two universities.
