Exploring How Galaxy Interactions Drive the Evolution of Interstellar Medium via Multi-wavelength Observations

It is essential to explore the interstellar hydrogen gas filling galaxies to understand the star formation and the evolution of galaxies. Investigating interstellar medium requires multi-wavelength observations because interstellar gas exists in a wide range of physical states, from hydrogen molecular clouds at -263 degrees Celsius to high-temperature plasma at around 10 million degrees. Therefore, observing across a broad range of wavelengths is critical to elucidate these properties fully. However, previous studies assumed that gases in vastly different physical states would not interact with each other, leading to a lag in multi-wavelength, multi-faceted studies. Our study has shown that phase transitions between gases with different physical quantities occur frequently and play a crucial role in galactic evolution. Specifically, I focus on “collisions” between galaxies. By investigating the mechanism of star formation triggered by large-scale collisions of cold hydrogen gas, as well as the formation of extended high-temperature plasma, I analyzed interstellar gas beyond the traditional boundaries of radio, X-ray, and optical/infrared wavelengths. I have recently extended my study to higher-energy phenomena by comparing diffuse gamma rays and radio emissions. Since galaxy collisions occur frequently throughout the universe, these events are expected to provide insights into the dynamics of energy and matter not only on galactic scales but also on a cosmic scale.

Testing Standard Cosmological Model by Precision Measurement of Large Scale Structure of the Universe

Thanks to the advancement of astronomical observation technology, a standard model describing the evolution of the universe was established in the 2000s. According to this standard model, known matter constitutes only about 5% of the universe, with the remaining 95% being comprised of unknown substances called dark matter, accounting for 27%, and unknown energy called dark energy, making up 68%. In the 2010s, observations of the large-scale structure of the universe have brought forth the possibility of inconsistencies in this standard cosmology. In this presentation, we will introduce the latest results obtained from measurements of the large-scale structure by the Subaru Telescope's Hyper Suprime-Cam (HSC), and discuss the potential breakdown in the standard cosmology.

STOchastic LAttice Simulation of Cosmic Inflation

Cosmic Inflation, an accelerated expansion phase, is a leading paradigm of the beginning of our universe. Not only does it realise a globally homogeneous and isotropic universe, but also it generates local fluctuations as seeds of stars, galaxies, clusters, etc. by stretching quantum vacuum fluctuations. For the first time, we provide a computer simulator of inflation called STOLAS including the gravity effect with use of stochastic culculus. We apply it for the primordial black hole, an interesting candidate of dark mattter.

Understand mechanisms of plant adaptation to nutritional stress to stabilize crop performance while reducing fertilization.

In Japanese agriculture, there is an old saying, 「苗半作」“Nae han saku”, meaning that half of the crop is determined by seedlings quality. Indeed, seedling production is an important process in crop cultivation. Plants can remember some environmental stresses. Nitrogen nutrition is a major environmental factor that regulates the growth and productivity of crops, but it is unclear whether plants remember a nutritional stress. My results strongly suggest that plants can remember nitrogen deficiency stress and react. Imprinting such memory, during seedling production process, would permit to create seedlings with both high yield and stress tolerance.

Leaf gas films in rice are conferred by wax synthesis gene (LGF1)

Floods impede gas (O2 and CO2) exchange between plants and the environment. A mechanism to enhance plant gas exchange under water comprises gas films on hydrophobic leaves. We used a rice mutant (dripping wet leaf 7, drp7) which does not retain gas films on leaves, and its wild-type (Kinmaze). Leaf Gas Film 1 (LGF1) was identified as the gene determining leaf gas films. LGF1 regulates C30 primary alcohol synthesis, which is necessary for abundant epicuticular wax platelets and gas films on submerged leaves.

Realization of resource-recycling manufacturing using the biological functions of insects

Many functional molecules are in-flask produced, and a various reactions and catalysts have been developed and utilized. However, the synthesis of molecules that require regio- and stereo-selectivity and functional group specificity has become a severe cost and waste problem due to the multistep process. This research is to integrate the field of functional organic material synthesis with ” bio-based transformation and synthesis technology” to develop a new chemical space unique to biological functions, which is difficult to achieve through organic synthesis.

Targeting the mosquito circadian clock to disrupt hearing function and behaviors

Billions of people worldwide are at risk of diseases spread by Aedes aegypti mosquitoes. Disease control programs which rely on insecticide application are coming under increasing pressure due to rising insecticidal resistance. The development of novel control tools with new targets is necessary but requires a better understanding of basic mosquito biology. Aedes aegypti courtship takes place in aggregations (‘swarms’) which form only at certain times of day. Within swarms, male mosquitoes rely on hearing to identify conspecific females by listening for their sexually dimorphic flight sounds. Both the clock and hearing can thus influence mosquito copulation success. Research in other species has found that the clock can directly influence hearing function, suggesting direct links between the clock and hearing. Disruption of clock function could interfere with hearing, and therefore courtship, behaviors. Working with collaborators in Japan, Taiwan and the USA, I explore the connections linking the clock, hearing and courtship to explore novel pathways to generate new methods of mosquito control.

Learning from medaka: How animals adapt to seasonal environmental changes

Japan has four distinct seasons. While we Japanese have incorporated seasonal changes into our lives and enjoyed them since ancient times, for animals, seasonal changes in the environment can sometimes be significant changes that affect their survival. Therefore, animals have acquired the ability to sense seasonal changes and flexibly change their physiological functions and behavior in the process of evolution. However, the molecular mechanisms of seasonal changes in physiological functions and behaviors, as well as the principles underlying the acquisition of these abilities, are still not fully understood. We are conducting research on medaka (Oryzias latipes) and related species, which show distinct seasonal responses, by applying technologies such as next-generation sequencing and genome editing to clarify “how animals adapt to seasonal changes” and “how they acquire the ability to adapt to seasonal changes”. We also aim to contribute to the implementation of a sustainable society under climate change by applying the knowledge we have learned from our research on medaka. In this presentation, I will introduce the mechanisms of seasonal adaptation in animals that are gradually becoming clear from our research.

Aiming at elucidation of visual functions in fish and development of eel larval food

We try to elucidate the visual cognitive abilities of fish to contribute to the fisheries industries through more efficient catches and aquacultural production of fish. We revealed higher-order visual circuits in the goby. The visual circuitry of a fish species that is expected to have higher cognitive abilities than the goby is also being revealed through collaborative research with the CNRS in France. In addition, aiming at development of feed for eel larvae, we revealed the development of taste organs as eel larvae grow and the brain regions activated by feed stimuli. Furthermore, our results of feeding experiments using feed added with orexigenic substances show that substance B may slightly promote growth on zebrafish larvae.

Eye movements and material and texture perception

We can instantly perceive the material and texture of objects, such as whether they appear glossy or transparent. Like color and shape, the perception of material and texture is subjective and cannot be fully understood without directly asking the observer. However, even without explicit answers, their perception can be estimated through eye movements, including pupil responses and focus distance. This study reports the relationship between eye movements and material and texture perception.

Exploration of Wearable Healthcare Devices Driven by Innovations in MEMS Technology

This research aims to create a biomarker detection technology that is distinct from conventional iron deficiency anemia testing technology by combining the technologies of “ferritin detection” and “skin device”, which enables non-invasive monitoring of physiological activity in the body, and enables early detection of iron deficiency anemia. In this research, we propose a skin device that can be attached to the skin like a band-aid and detects ferritin, which indicates iron deficiency in the body, from body fluids such as sweat. The final goal is to create a device that can be used in developing countries, based on the Stanford University-developed bio-design thinking as a method for considering the process of creating truly usable medical devices.

Development of coacervate-based protocell from low-molecular-weight compounds

In living systems, compartmentalization plays a crucial role for a variety of biomolecules to execute elaborate functions. As one of cell-like soft materials, coacervates, which are spontaneously formed through liquid-liquid phase separation (LLPS) of polyelectrolytes such as nucleic acids and polypeptides driven by multiple non-covalent interactions, have garnered significant attention as mimics of membraneless organelles inside living cells. This study report new coacervate-forming molecules based on low-molecular-weight compounds and their physical properties including stimuli responsiveness.

Discovery of Constant-Period Chaotic Oscillations in Cardiac Sarcomeres

We discovered constant-period chaotic oscillations in cardiac sarcomeres. Using high-precision optical microscopy (SL-nanometry), we observed that live cardiomyocytes heated to 37–42°C exhibit Hyperthermal Sarcomeric Oscillations (HSOs). Despite showing chaotic properties—such as fluctuations in amplitude, waveform, and irregular switching between synchronization and anti-synchronization of adjacent sarcomeres—the contraction-relaxation cycles maintain a constant period. We termed this phenomenon S4C (Sarcomere Chaos with Changes in Calcium Concentration) and identified a new kind of chaotic order we call "homeochaotic." This suggests that the chaotic instability in HSOs allows sensitive response to calcium changes while maintaining rhythmic stability, potentially contributing to the autonomous coping ability of cardiomyocytes.

The effect of diet on the prevention of lifestyle diseases via the intestinal immune system.

The intestinal immune system is an important mechanism for preventing bacterial infections and maintaining homeostasis. The intestines are constantly stimulated by various components, such as food and gut microbiota, and the impact of this on the immune system is thought to play a role in health and disease. This study focused on how dietary changes affect antibody production in the immune system and aimed to elucidate its association with the onset of lifestyle-related diseases. Specifically, we examined changes in the intestinal immune system in mice fed diets that induce lifestyle-related diseases, such as high-sucrose and high-fat diets.

Targeting adipose tissues at tumor microenvironment of metastatic ovarian cancer

Adipocyte-rich omentum offers good soil for disseminating ovarian cancer (OvCa), however, not much has been clarified. We have reported that the primary human adipocytes dedifferentiate into omental adipocyte-derived fibroblast (O-ADF), which possess both mesenchymal stem cells and cancer-associated fibroblasts, under the existence of malignant ascites, and enhance the proliferative and migratory characteristics of OvCa cells. In this study, in order to target adipocyte dedifferentiation as a novel OvCa treatment strategy, we developed a new lipid droplet fluorescent sensor with high photostability and ascites compatibility, and conducted chemical library screening with an assay system utilizing this fluorescent sensor. By adding malignant ascites (n = 3), some compounds were picked up as drug candidates targeting adipocyte dedifferentiation process. Further results of in vitro, as well as in vivo, validation analysis will be reported.

Integrated Genomic Research of Brain Malformation and Dementia Approached through Genomic Instability

Brain malformation typically manifests in infant, while dementia occurs in adults. These have been recognized as entirely distinct diseases. However, recent research has begun to reveal common genomic pathologies between the two. Therefore, this study proposes the working hypothesis that genomic instability may be the ‘Missing Link’ between brain malformation and dementia. This hypothesis will be tested through advanced genomic analyses, including long-read sequencing, with the goal of preventing early-onset neurodegeneration associated with brain malformation and developing treatments for dementia.

Does the soul create itself?　For the dream analysis of “Hikikomori” young man

There are many different theories about how the soul changes. One school of thought is that the mind has stages of development, and that it develops depending on the stage. Another school of thought is that mental problems originate in the mother-child relationship in infancy, and that if the mind is given something to replace that mother-child relationship, it will be healed. According to Jung, C.G., the soul is self-transforming. In this case study of dreams, I would like to show that the mind tears itself apart and then re-generates itself.

Scholarly Edition of 3D Models: 3D models as a linga franca for multidisiplinarity

The Byzantine Empire’s Christian churches hold immense historical and cultural value, yet many are deteriorating, and research progress is limited by a lack of interdisciplinary collaboration. To address this, scholarly edited 3D models are proposed to transform these churches into rich historical resources. These 3D editions, enhanced with multimedia data and organised information, can foster interdisciplinary research and new insights. By providing precise spatial details, 3D models capture important elements like mural and inscription locations—information that conventional 2D media cannot convey. Acting as a lingua franca across disciplines, these scholarly editions bridge knowledge gaps and support collaborative study, ensuring that Byzantine cultural heritage is preserved and fully understood for future generations.

A constructive method for the pickup and delivery problem with item loading platform assignment

We solved the optimization problem of AGVs in a production environment. We consider the pickup and delivery problem with item loading platform assignment (PDP-ILA) for automated guided vehicles (AGVs) with multiple loading platforms. We propose a set packing model for use in an AGV control system that must be solved within one second. Therefore, we suggest a constructive method using a rectangular packing model. Our computational experiments show that this method efficiently creates pickup-and-delivery plans within the one-second limit.
