Animal Sciences
Stag beetles are highly popular insects as pets in the world. During the larval stage, a pair of orange spot is observed exclusively on the abdomens of female larvae. These structures common…
ISEF · 2026
Plant Sciences
Whether plants—which lack a nervous system—can exhibit "intelligent" behaviors such as learning and stimulus discrimination remains a fundamental question in biology. I addressed this questi…
ISEF · 2026
Behavioral and Social Sciences
Navigation inflexibility is a symptom observed in approximately 50% of early Alzheimer's disease (AD). However, why and how this disorder occurs has remained unclear. Computational modeling…
ISEF · 2025
Behavioral and Social Sciences
Equine-assisted intervention (EAI) is known to improve humans’ psychological and physical functions. Equine-assisted activity (EAA) is one service of EAI that involves interaction between hu…
ISEF · 2025
Computational Biology and Bioinformatics
Mental imagery is a sophisticated brain function that enables high-level inference and creation. The ability for mental imagery varies among individuals along various dimensions, such as viv…
ISEF · 2025
Earth and Environmental Sciences
Columnar jointing is a well-known feature of frozen magma flows. World-famous examples include the UNESCO world heritage site, the Giant's Causeway, UK. Columnar jointing can be divided into…
ISEF · 2025
Animal Sciences
Bumblebees are social insects: one queen and many worker bees live in the nest. In the Japanese bumblebee Bombus ignitus, the queen lays fertilized diploid eggs that develop into female work…
ISEF · 2025
Physics and Astronomy
My research interest has expanded from simple harmonic oscillations to include various forms of damped oscillatory systems. Just as the oscillation of a building during an earthquake or a sw…
ISEF · 2024
Robotics and Intelligent Machines
This study focuses on the fundamental aspects of LLMs (Large Language Models) such as GPT, Bard, Llama 2, Claude, and more, particularly their inherent biases. These models, some engaging ov…
ISEF · 2024
Chemistry
I developed a novel photochromic system using methylene blue with ascorbic acid and investigated the optimal photochromic conditions. The photochromic solution is environmentally friendly an…
ISEF · 2024
Chemistry
Artemisinin, a sesquiterpene lactone isolated from a plant, is currently used as a superior antimalarial agent. Because of a recent discovery of artemisinin-resistant parasites, there is an…
ISEF · 2024
Chemistry
Onion, ginger and tea, which are common foods, have antioxidant activity due to polyphenolic compounds such as flavonoids. In this study, I employed 1,1-diphenyl-2-picrylhydrazyl (hereinafte…
ISEF · 2024
Animal Sciences
On the coast of Japan, the sea urchins (Heliocidaris crassispina) of the same species gather together, while they are separated from their enemy, or the starfish (Patiria pectinifera). We fo…
ISEF · 2023
Animal Sciences
The tidal snail Cerithidea moerchii living in brackish mud flat in our town (habitat A) was observed frequently climbed up on the reed stem above the water. Snails of this species were also…
ISEF · 2023
Physics and Astronomy Second Award
Ants can climb smooth walls such as glass even if the wall is vertical or overhanging. It is well known that geckos use van der Waals forces between the foot and the wall to adhere to walls.…
ISEF · 2023
Robotics and Intelligent Machines
Accidents involving visually impaired people while walking are one of the serious social issues (e.g., falling off station platforms and crossing crosswalks without acoustic signals). The ri…
ISEF · 2022
Chemistry
The purpose of this research is to establish an environmentally friendly process for manufacturing transparent wood. I focused on improvements of the method described in the paper published…
