Problem Solving Will Not Reduce the Number of Research Themes―It Will Open up New Research Areas

From his extensive research in blind source separation, Senior Distinguished Researcher Hiroshi Sawada has received worldwide acclaim for his work with a domestic research partner on independent low-rank matrix analysis, namely, the development and integration of independent component analysis and non-negative matrix factorization. He has also ventured into the field of neural networks. We asked him about his research achievements and his attitude toward enhancing his research activities.

Progress in the Development of IOWN Technology

Technical improvements in full-stack layers are essential to develop a future infrastructure with higher capacity, lower latency, and lower power consumption toward a cyber-physical society. NTT announced its roadmap for this technology, the Innovative Optical and Wireless Network (IOWN), in April 2020 and has accelerated to implement the roadmap with global partners of the IOWN Global Forum (IOWN GF). IOWN GF developed and published a series of deliverables on Open All-Photonic Network (Open APN), IOWN for Mobile Network, Fiber Sensing for Open APN, Data-Centric Infrastructure, IOWN Data Hub, and a Reference Implementation Model. This article provides an overview of these deliverables and describes the growth of IOWN GF and its activities.

Research on Reducing CO2 in the Ocean through the Application of Genome Editing Technology to the Carbon Cycle of Algae, Fish, and Shellfish

According to the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report, 57.7% of carbon dioxide (CO2) emissions into the atmosphere are absorbed by forests, and 34.6% is absorbed by the ocean. In this article, we interviewed Distinguished Researcher Dr. Sousuke Imamura about "CO2 reduction technology in the ocean based on application of the genome editing technology."
