Prof. Hideaki Fujiwara (Specially Appointed Associate Professor) at the Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, has published a paper presenting research findings that quantitatively analyze the scholarly impact of research articles published in major astronomy and astrophysics journals between 1996 and 2024, based on bibliographic database information.   In this study, annual trends in key metrics such as the number of publications and citations were analyzed using data obtained from the bibliographic databases Scopus/SciVal. The results show that, on average, citations to astronomy and astrophysics papers increase approximately 2-4 years after publication and then continue for about 10 years, suggesting a characteristic timescale of knowledge use in the field.   Scholarly impact is sometimes assessed using citation-based metrics. However, this study suggests that evaluating impact solely on the basis of short-term citation counts has limitations and requires careful interpretation.   This research was published in the academic journal Publications of the Astronomical Society of Japan on January 28, 2026.

Tetrodotoxin (TTX) is one of the most famous natural toxins as a pufferfish toxin. This toxin is a potent and highly selective blocker of voltage-gated sodium channels. In addition to pufferfish and other diverse marine organisms, TTX is also found in terrestrial amphibians such as newts. Owing to its unique structure, its strong pharmacological activity that can cause fatal food poisoning, and its broad distribution across taxonomically diverse organisms, TTX has been studied in multiple disciplines, including organic chemistry, biology, food safety science, chemical ecology, and neuroscience. Nevertheless, its origin and biosynthetic pathway have remained unresolved. In this study, Associate Professor Yuta Kudo of the Frontier Research Institute for Interdisciplinary Sciences, Tohoku University, led an international collaborative project with Shugo Horie (undergraduate student) and Professor Mari Yotsu-Yamashita of the Graduate School of Agricultural Science, Tohoku University, and Associate Professor Charles Hanifin of Utah State University. Kudo and co-workers discovered five new tetrodotoxin analogues from toxic newts and elucidated their chemical structures. By identifying these analogues that differ in oxidation state and stereochemical configuration, Kudo and co-workers were able to propose a biosynthetic pathway for terrestrial tetrodotoxin. Furthermore, the inhibitory activities of these newly identified analogues against voltage-gated sodium channels were evaluated, providing new insights into their structure–activity relationships. The findings have been published online on February 4, 2026, in the Journal of Natural Products, a peer-reviewed journal of the American Chemical Society (ACS). The article is available as open access through Tohoku University’s APC support program.     Publication Details: Title: Identification of Deoxy- and epi-Tetrodotoxin Analogues from the Newt Cynops ensicauda popei Suggests Stepwise Oxidation in Terrestrial Tetrodotoxin Biosynthesis  Authors: Shugo Horie, Charles T.

Developing new materials can involve a dizzying amount of trial and error for different configurations and elements. It is no wonder that artificial intelligence (AI) has seen a surge of popularity in energy materials research for its potential to streamline this time-consuming process. However, fully autonomous workflows that connect high-precision experimental knowledge to the discovery of credible new energy-related materials remain at an early stage.   A team of researchers at the WPI-Advanced Institute for Materials Research (WPI-AIMR), Tohoku University, created the Descriptive Interpretation of Visual Expression (DIVE) multi-agent workflow to streamline the material researching process. The system extracts information from images in a database of over 30,000 entries from >4,000 scientific publications to propose new materials within minutes.   The findings were published in Chemical Science on February 3, 2026.

DIVE systematically organizes the information it pulls from existing literature regarding solid-state hydrogen storage materials. Its accuracy and coverage of data extraction was 10-15% better than commercial models, and over 30% better compared to open-source models. DIVE is easy to use, as input resembles a regular conversation. Simply provide DIVE with what criteria you are looking for, and it will draw from its database to propose suitable materials. It also demonstrates the ability to propose entirely novel materials that haven't been reported in the literature before.   "DIVE can convert literature-embedded scientific knowledge into actionable innovation, offering a scalable pathway for accelerated discovery across chemistry and materials science," says Distinguished Professor Hao Li (WPI-AIMR).   This research is significant because it builds a reliable, end-to-end pipeline that converts key experimental results otherwise hidden in paper figures into high-quality, machine-readable data, enabling faster and more accurate scientific synthesis and discovery. It reports clear performance gains over common extraction approaches and produces a large, curated hydrogen-storage database (DigHyd) built from thousands of papers, which can be directly queried and used to guide new material design. The Digital Hydrogen Platform (DigHyd: www.dighyd.org) is the first digital platform for hydrogen storage materials design, and also the largest experimental and computational solid-state hydrogen storage database reported to date.   "The reason we want to know so much about hydrogen storage materials is because they are a key bottleneck for making hydrogen-based clean energy practical, safer, and more affordable," explains Li. "Our proposed workflow with DIVE has the potential of accelerating evidence-based discovery, which means shorter turnaround times from when research is published to when it actually gets implemented in real-world technologies that help the environment."

An international research team has discovered a supermassive black hole growing rapidly while radiating bright X-rays and radio waves. This combination of features contradicts the current models of black hole growth, requiring astronomers to look for a new explanation.   Supermassive black holes, millions to billions of times the mass of the Sun, sit in the centers of most galaxies. They grow by pulling in surrounding gas. As gas spirals inward, it can power a compact region of hot plasma known as a corona which emits X-rays. Some supermassive black holes also form a jet of outflowing material that emits strongly at radio wavelengths.   But if gas falls towards a supermassive black hole too quickly, radiation from the gas starts to push back on the material flowing behind it, causing the flow to slow down. This sets a self-regulating “Eddington Limit,” a speed limit on how fast gas can flow in. Like most speed limits, the Eddington Limit is broken sometimes, enabling rapid mass build-up over short cosmic timescales.     Figure: Artist’s impression of a supermassive black hole system. Infalling gas forms a bright corona near the black hole. In some systems, a jet is launched. (Credit: NASA/JPL-Caltech)   To test whether such extreme growth occurs in the early Universe, a team led by scientists at Waseda University and Tohoku University, including Prof. Kohei Ichikawa of FRIS, used the Subaru Telescope to measure the motion of gas around a supermassive black hole that existed when the Universe was less than 1.5 billion years old and found that it is accreting gas at 13 times the Eddington Limit. More surprisingly, the object also emits bright X-rays and radio waves. In the current models, super-Eddington accretion should change the gas flow and suppress X-ray and radio wave production. This unexpected combination hints at physical mechanisms not yet fully captured by current models of extreme accretion.   The team thinks the object is in a short-lived transitional stage. A sudden burst of inflowing gas may have pushed the system into a super-Eddington state, while a bright X-ray corona and a strong radio-wave emitting jet remained simultaneously energized for a limited time before the system settles toward a more typical regime.   This discovery offers a rare glimpse of time-variable black hole growth in the early Universe—an important step toward understanding the rapid growth of massive black holes.

Prof. Yueh-Hsuan Weng (associate Professor )at the Frontier Research Institute for Interdisciplinary Sciences, Tohoku University (Cross-appointed with the Inamori Frontier Program, Institute for Advanced Study, Kyushu University) has published a co-authored book titled 'Generative AI, Contracts, Law and Design', in which he was in charge of the chapter titled 'Proactive Privacy Communication Design for Emotional Robots'.   This book explores how generative AI and design are reshaping the law, legal communication, and contracting—moving beyond automation toward collaboration and meaningful outcomes. Combining theory and practice, it addresses challenges such as privacy, communication, financial well-being, responsible AI use, and the language of contracts. This edited book breaks new ground in exploring how generative AI and design are acting as catalysts for change in law, legal communication, and contracting. Together, they are transforming the way we think and act—moving beyond automation toward collaboration, actionability, and achieving goals. Bringing together theoretical insights and practical experiments, the book features contributions from scholars and practitioners working at the intersection of law, business, technology, and design.    Publisher: Springer Singapore Book Name: Springer PLBI Series: Generative AI, Contracts, Law and Design Date Published: November 2025 Format: Hardback ISBN： 978-981-95-2057-2  https://link.springer.com/chapter/10.1007/978-981-95-2058-9_7  

The pH, or the acidity or alkalinity of an environment, has long been known to affect how efficiently catalysts drive key electrochemical reactions. Yet despite decades of research, the atomic-scale mechanisms behind these pH effects have eluded scientists.   A new study sheds light on this mystery by decoding how electric fields, surface properties, and charge dynamics intertwine to govern catalytic performance. The findings mark a significant step toward rationally designing catalysts that perform efficiently in a range of environments, paving the way for next-generation clean energy technologies.   Details were published in the Journal of Materials Chemistry A on 26 September 2025.   Traditional models have explained pH-dependent activity mainly through the computational hydrogen electrode (CHE) model and the Nernst equation. These frameworks linked shifts in activity to changes in potential and proton concentration. However, the new research shows that the reality is far more complex, involving a web of interfacial electric fields and molecular interactions that standard models cannot fully capture.   Recent advances in both experimental and computational methods have revealed that properties such as dipole moments, polarizability, and the potential of zero charge (PZC) play a critical role. These factors determine how molecules and ions interact with catalyst surfaces, directly influencing reaction rates and selectivity.   By bringing together insights from electrochemistry, physics, and computational modeling, the research highlights how these interfacial effects manifest across a wide array of reactions, including hydrogen evolution (HER), oxygen reduction (ORR), carbon dioxide reduction (CO₂RR), and nitrate reduction (NO₃RR). These are among the most important reactions for renewable energy conversion, fuel generation, and environmental remediation.   Schematic illustrations of: (a) the methods dealing with pH for the classic CHE model and the electric field (EF) pH-dependent model; (b) surface coverage on Pt (111) revealed by the electric field model: HO* dominates under alkaline conditions, while H* prevails under acidic conditions; (c) simplified pH-dependent activity volcano. ©Hao Li et al.   "Our work shows that pH effects are not just surface-level phenomena; they are governed by the electric field environment at the interface," said Hao Li, a professor from Tohoku University's Advanced Institute for Materials Research (WPI-AIMR) who led the study. "By understanding and modeling these fields, we can predict how catalysts behave under different pH conditions and ultimately design materials that are more efficient and sustainable."   The study also introduces advanced theoretical frameworks that go beyond traditional thermodynamic descriptions. Notably, the reversible hydrogen electrode (RHE)-referenced Pourbaix diagram and the pH-dependent microkinetic volcano model provide a more accurate depiction of catalytic activity and stability across varying electrochemical conditions.   (a-c) Electric field effects on the adsorption free energies of ORR adsorbates.

By integrating experimental data with computational simulations, researchers are now able to map how subtle changes in pH shift reaction pathways and determine overall efficiency. Looking ahead, the research team plans to combine molecular dynamics with machine learning potentials to simulate reaction conditions in real time. This approach could unlock even deeper insights into how catalysts evolve during operation, further accelerating the design of high-performance materials for a sustainable energy future.   (a) Scaling relations of the charge extrapolated Volmer, Heyrovsky, and Tafel transition state energies vs. H* binding energy.

From November 5-7, 2025, the Symposium on Social Robots and Ethical Design, jointly organized by the Institute for Advanced Study (IAS) at Kyushu University and FRIS at Tohoku University, convened as a hybrid event in Aobayama Campus. Under the banner “Toward Design-centered Governance for Social Robots”, the symposium addressed the regulatory, ethical, design and governance challenges posed by increasingly capable AI-enabled social robots.  The symposium brought together researchers from engineering, design, ethics, law, and social sciences to provide examination on the challenges and opportunities posed by social robots. The thematic sessions covered four interconnected areas, underscoring the symposium’s central commitment to viewing social robots as socio-technical systems whose development must be informed by integrated insights from technology, behavior, and normative frameworks. In the domain of robotics design and deployment, researchers presented studies on how robots can be incorporated into real living environments. Presentations from Tohoku University demonstrated the use of living-lab and experimental settings to evaluate how individuals interact with assistive robots in everyday situations. Contributions from National Taiwan University highlighted soft robotics and adaptive locomotion mechanisms that enable robots to navigate complex human environments more effectively. Additional work explored how visual complexity and familiarity influence user comfort and attentiveness when engaging robots. Other speakers analyzed how both the physical and psychological dimensions of human–robot interaction (HRI)can be shaped through careful design choices that promote a sense of safety, empathy, and trust. The second thematic focus on HRI offered behavioral and cognitive perspectives. Scholars examined how emotional responses such as acceptance, rejection, or perceived social friction emerge in interactions with social robots. Research using game-based simulations demonstrated how robots can affect participants’ moral reasoning processes. Another presenter introduced findings about the social acceptance of anthropomorphism in dog robots. The symposium further highlighted how cultural narratives found in science fiction and digital games can illuminate public expectations, anxieties, and imaginaries surrounding future robot governance. Presentations within the policy and governance theme addressed broader societal and regulatory implications. Speakers discussed the growing role of robots in ageing societies and the need for human-centered approaches to care technologies that recognize emotional and moral dimensions of vulnerability. The presenters emphasized that recognizing overlooked needs is important. Others analyzed how systematic reviews and stakeholder consultations contribute to more inclusive robot governance frameworks. The longstanding issue of “responsibility gaps” was also examined.  The final set of presentations turned toward ethical design and governance, emphasizing the significance of non-binding ethics standards as complementary tools to formal legal regulation. Experts analyzed how socio-technical standards developed within the IEEE framework are being adopted globally, noting their increasing influence on engineering practice. Cross-cultural studies from Japan and Norway provided comparative insights into consent, privacy, and social acceptance of robots. Researchers argued for the integration of both philosophical reflection and empirical data in the development of robot ethics methodologies.  Taken together, these contributions demonstrated the inherently multidisciplinary nature of responsible robotics. The symposium underscored that engineering innovation alone cannot address the complexities of deploying social robots into public and private spaces. Instead, effective governance requires design-centred approaches that incorporate behavioural insights, ethical standards, and legal considerations from the outset. The discussions also reflected a broader shift in robotics research: from industrial automation toward socially embedded systems in homes, care settings, and everyday public environments. This shift signals that future progress in robotics must be aligned with societal needs and normative expectations. Through its diverse range of perspectives, the symposium offered a valuable foundation for continued research, collaboration, and the development of robust governance frameworks for social robots.

The origins of extremely high-energy particles that fill the Universe - such as protons, electrons, and neutrinos - remain one of the longest-standing mysteries in modern astrophysics. A leading hypothesis suggests that "explosive transients," including massive stellar explosions (supernovae) and tidal disruption events (TDE) caused by stars being torn apart by black holes, could be the cosmic engines driving these energetic particles. Yet, this idea has never been rigorously tested.   A research team has conducted the first systematic search for optical counterparts to a neutrino "multiplet," a rare event in which multiple high-energy neutrinos are detected from the same direction within a short period. The event was observed by the IceCube Neutrino Observatory, a massive detector buried deep within the Antarctic ice.   The team was led by Seiji Toshikage, a graduate student at Tohoku University's Graduate School of Science, Shigeo Kimura, a professor at Tohoku University's Frontier Research Institute for Interdisciplinary Sciences (FRIS), and Masaomi Tanaka, also from the Tohoku University's Graduate School of Science.   By analyzing wide-field optical data that coincided both spatially and temporally with the neutrino multiplet, the researchers sought visible evidence of possible astrophysical sources. However, their investigation found no supernovae, TDEs, or other explosive transients at the corresponding times and positions.   Arrival direction of a high-energy neutrino multiplet event determined by the IceCube experiment, overlaid on the visible night sky (generated with Stellarium).

The red ellipse indicates the 1σ uncertainty estimated by IceCube. ©Stellarium, Zwicky Transient Facility   This absence of optical counterparts is, paradoxically, highly informative. The non-detection allows the team to place stronger constraints than ever before on how bright and how long such explosive events could be if they were to produce neutrino multiplets. The findings significantly narrow the possible origins of the Universe's most energetic particles and mark an important step toward solving one of astrophysics' most fundamental puzzles.   "Although we didn't find any transient sources this time, our results show that even non-detections can provide powerful insights," said Toshikage. "They help us refine our models and guide future searches for the true sources of high-energy neutrinos."   Looking ahead, the team plans to conduct rapid optical follow-up observations of newly detected neutrino multiplets as soon as the IceCube collaboration reports them. They expect that these efforts, building on the analysis methods developed in this study, will bring researchers closer to identifying the astrophysical engines that generate high-energy particles throughout the cosmos.   The study was published in The Astrophysical Journal on October 23, 2025.   Constraints on the luminosity and its evolution timescales of explosive transients that could serve as sources of high-energy particles, based on the present multi-messenger observations.

A research team has taken a major step forward in the field of spintronics, a technology that uses not only the charge but also the spin of electrons to create faster, smarter, and more energy-efficient electronic devices. Their discovery could pave the way for the next generation of memory chips that combine high speed with low power consumption.   In spintronic memory, information is stored using tiny magnetic regions called magnetic domains. A magnetic domain with its magnetic moments pointing upward represents a "1," while one pointing downward represents a "0." Data can be read or written by shifting these domains with an electric current. The boundaries between them, known as domain walls, play a crucial role, as moving domains means moving these walls. Achieving fast and efficient domain wall motion is essential for developing advanced memories such as magnetic shift registers and three-terminal magnetic random access memories (MRAM).   The researchers focused on an artificial antiferromagnetic thin film made of cobalt (Co), iridium (Ir), and platinum (Pt) layers. This carefully engineered structure, in which two Co layers are separated by an Ir layer and sandwiched between Pt layers, makes the two Co layers aligned in opposite directions - an arrangement known as antiferromagnetic coupling. The Pt layers help drive motion in the material through a phenomenon called the spin Hall effect, which generates streams of electron spins that push on the magnetic moments in the Co layers.   At first glance, it might seem that the spins generated from the top and bottom Pt layers would cancel each other out because they have opposite orientations. However, the team discovered that these opposing forces actually combine in a unique way, working together to move the domain walls instead of stopping them. This dual-torque mechanism was confirmed through both experiments and numerical simulations, marking the first demonstration of this type of spin-driven motion in such a material.   The researchers went a step further by introducing a subtle gradient in the thickness of the Co layers, breaking the structure's symmetry. This created an additional effective magnetic field that made it even easier to move the domain walls. As this field increased, less current was needed to drive the motion, and the walls moved faster, allowing for information to be processed more efficiently.   The findings open up new possibilities for energy-saving, high-speed spintronic memory devices. Technologies like magnetic domain wall memory and three-terminal MRAM, which use this type of domain wall motion, could play a key role in the digital infrastructure that supports artificial intelligence and the Internet of Things.   Image for electron spins acting on the antiferromagnetically-coupled artificial magnetic structures with domain wall. ©Takeshi Seki   "Our results show a new way to control domain wall motion using combined spin torques in an artificial antiferromagnet," said the research team. "This discovery could bring us closer to creating next-generation spintronic devices that are faster and consume far less energy than today's electronics," said Takeshi Seki, a professor at the Institute for Materials Research at Tohoku University, and co-author of the paper.   While spintronics has traditionally relied on ferromagnetic materials, antiferromagnetic spintronics is now emerging as a promising frontier, offering the potential for greater miniaturization and higher operation speeds. The team's demonstration of current-induced domain wall motion in an artificial antiferromagnetic structure marks an important milestone toward that goal. Moving forward, they aim to fine-tune the effective magnetic fields that control this motion, unlocking even higher performance and pushing spintronic technology into a new era.   Details of the researchers' breakthrough was published in the journal Advanced Science on October 17, 2025.
