The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), in collaboration with Sony Semiconductor Solutions Corporation (Sony), has developed the world's first practical surface-emitting laser that employs quantum dot(QD) as the optical gain medium for use in optical fiber communication systems.

A joint research team from Nagoya University Institute for Space-Earth Environmental Research, the University of Oslo Faculty of Mathematics and Natural Sciences, Kyoto University Institute for Integrated Cell-Material Sciences, and the National Institute of Information and Communications Technology conducted ionospheric tomography analysis using data from Japan's ultra-dense GNSS observation network. They clarified, for the first time, the 3D characteristics of ionospheric electron density fluctuations, spatially and temporally evolving, immediately following the Noto Peninsula Earthquake of 2024.

A research group led by Prof. Yoshinao Kumagai of Tokyo University of Agriculture and Technology, in collaboration with Mr. Junya Yoshinaga of TAIYO NIPPON SANSO CORPORATION, Assistant Prof. Shogo Sasaki of Nara Women’s University, Prof. Takeyoshi Onuma of Kogakuin University, Prof. Masataka Higashiwaki of Osaka Metropolitan University / National Institute of Information and Communications Technology, and Dr. Yuzaburo Ban of TAIYO NIPPON SANSO ATI CORPORATION, has successfully developed a technique for precise control of n-type conductivity in high-speed growth of β-Ga₂O₃ homoepitaxial layers using their proprietary low-pressure hot-wall MOVPE method.

A research group led by FUJINO Misako and HARUNO Masahiko at the National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki Ph.D.), has demonstrated that experiencing active flight in VR allows individuals to predict that they can transition to a safe state even if they fall from a height, thereby reducing fear responses. This discovery challenges the traditional understanding that fear extinction necessarily requires repeated exposure to fear-inducing stimuli.

The National Institute of Information and Communications Technology (NICT, President: TOKUDA Hideyuki, Ph.D.) has revealed, through fMRI-based brain activity analysis, that multiple regions in the human cerebral cortex flexibly represent numerical quantity. This finding comes from research by HAYASHI Masamichi (Researcher (Tenure-Track)) at Center for Information and Neural Networks (CiNet), part of NICT’s Advanced ICT Research Institute, in collaboration with the University of Tokyo’s graduate student KIDO Teruaki (NICT cooperative visiting researcher), and Prof. YOTSUMOTO Yuko.
