RIKEN: The 100th Anniversary of a Major Research Organization of Japan
― The Day the 113th Element Was Born

December 1, 2016. On this day, a press conference took place in a Fukuoka city hotel that deserves to go down in the history of science in Japan. The day before, at the Institute of Physical and Chemical Research (known as RIKEN) in Wako, Saitama Prefecture, the acceptance of an official name for a new chemical element artificially created in Japan was announced. Its name was nihonium, its symbol Nh, and its atomic number 113. The periodic table is an organizational system for the elements, and is to science what the alphabet is to the English language. But until recently, the elements that fill the table were all officially discovered in the countries of Europe and North America, and none in Japan. In fact, in 1908 a Japanese had discovered the forty-third element and proposed the name nipponium for it. The fourth president of ... ... [Read more]

Dialogue: The fundamental bases for the Japanese people
To the fundamental bases for the Japanese people
― The possibility of initiatives for integrating archaeology with anthropology

  Editorial staff: This special feature discusses research on the lives of ancient people beyond the boundaries of study areas, with a focus on the time from the Jomon period to the Kofun (ancient tomb) period. Please tell us what you think of the time from the Jomon period to the Kofun period. Shinoda Kenichi: Genome information shows that the genetic structure of modern-day Japanese was more strongly influenced by the immigrant Yayoi people who came to Japan from Korea and China than by the Jomon people, who constituted the fundamental bases for the Japanese people. It seems that because the people from the Korean and Chinese continents were agricultural people, they had a strong ability to increase the population. Anthropological studies on the Jomon and Yayoi periods have revealed that modern-day Japanese living on the main island of Japan have many genes derived ... ... [Read more]

Society and Science on iPS Cells
― Think about the next decade with a focus on the ethical, legal and social issues

In 2006, a research team led by Professor Yamanaka Shinya at Kyoto University reported that it had generated iPS cells in mice. The following year, the team reported that iPS cells could be generated in human beings as well. Ten years have passed since then. What has happened in the ten years following the first generation of iPS cells? This special feature looks at the progress of the research with a focus on the ethical, legal and social issues (ELSI). This paper organizes ELSI in order so that it can be referred to by readers. Introduction Japanese regenerative medicine has seen many changes since a research team led by Professor Yamanaka Shinya at Kyoto University first generated iPS cells. The biggest change is that the world’s first-ever clinical research using iPS cells derived from patients was conducted, and that clinical research using other people’s ... ... [Read more]

Interview: Artificial Intelligence

  Professor Sakura Osamu (left) had an interview with Professor Nishigaki Toru about the artificial intelligence (AI) on September 2, 2016, at the Office of the Dean of the University of Tokyo Interfaculty Initiative in Information Studies.   Professor Sakura (hereinafter “Sakura”): First, I would like you to give a brief self-introduction. I have just read your book entitled Big Data and Artificial Intelligence: Gain Insights into Their Possibilities and Traps, which you published in July 2016 through Chuokoron-Shinsha Inc. In this book, you discuss the cultural and social background behind artificial intelligence (AI), with relation to recent big data and singularity. I found it very interesting. I am remembering the excellent impression I got from reading your book for general readers entitled AI: The Concepts Behind Artificial Intelligence, which you first published in 1988 through Kodansha Ltd. Big Data and Artificial Intelligence came ... ... [Read more]

From the Subaru Telescope to TMT

KASHIKAWA Nobunari, Associate Professor, National Astronomical Observatory of Japan

It has been fifteen years since the Subaru Telescope began operation. It stands as a symbol of the technology on which Japan prides itself. The telescope has been used to observe a wide range of astronomical objets throughout the universe, from the solar system to distant galaxies more than 10 billion light years away, and has produced a multitude of achievements. The Subaru Telescope has made a number of findings about the universe, and at the same time has presented us with many new questions. We have a boundless curiosity to peer into the unknown, and this pure desire to know more has driven us to reach even higher and build a new larger telescope. In this article, we introduce the TMT (Thirty Meter Telescope) that is currently being constructed and some of the new doors to the universe that it will open.... [Read more]

Electricity Reform Is the Best Performer for the Growth Strategy

ITOH Motoshige, Professor at the Graduate School of Economics of University of Tokyo

The Great Earthquake and Tsunami Disaster that stopped nuclear power generation revealed the vulnerability of Japan’s electricity system ABE Junichi (AJ): The Government decided in a cabinet meeting and submitted to the Diet the Bill for Partial Revision of the Electricity Act in March to achieve electricity system reform. Professor Itoh, you had, in the capacity of the chairman of the “Electricity System Reform Expert Committee,” compiled a report in February 2013 proposing the full liberalization of electricity retail sales and the separation of power generation and power transmission. The report became the pillar of electricity system reform. Why should the electricity system be reformed now?... [Read more]

Corporations and Geniuses― The main man behind the invention of blue LEDs speaks.
Serendipity: No Such Thing Exists
Interview with Amano Hiroshi, Professor, Graduate School of Engineering, Nagoya University

22 October 2014, Professor Amano visited the Prime Minister’s Office (From the website of the Prime Minister of Japan and his Cabinet)

The invention of blue LEDs was the product of the conviction of a researcher who does not even view effort as really effort. How should corporations deal with capable researchers?
The dream of all researchers is to make possible that which is considered to be impossible. They seek to conceive an invention that breaks accepted theories. However, the road to innovations that destroy paradigms is a long one, and they can only be brought about through years of research that goes unnoticed. This was the case of the research of Amano Hiroshi, a professor at Nagoya University who worked on inventing blue light-emitting diodes (LEDs). In 1983, Professor Amano enrolled in a master’s program at Nagoya University. To produce gallium nitride crystal, a material for blue LEDs, he lit his device every day except... [Read more]

The Robot & AI Revolution I
Robots will Change Work & Industry

It has two eyes on its flat head. It cannot walk with two legs, but it has two triple-jointed arms—with shoulders, elbows and wrists—that it can move freely… The external appearance of NEXTAGE, a robot developed by Kawada Industries, is totally different from that of the clunky-looking industrial robots that have seen popular widespread use in Japan until now. The difference is not only in its appearance. In contrast to conventional industrial robots, which pride themselves on speed and power, and operate under the assumption that human beings will not go near them, NEXTAGE aims to coexist with humans. It’s not merely a piece of ‘equipment,’ but a ‘partner.’ But Kawada Industries didn’t develop NEXTAGE simply to give it a friendly appearance and try to create a nicer atmosphere on the production floor. There is a genuine business opportunity behind it. ... [Read more]

The Robot & AI Revolution

SAKURA Osamu, PhD., Dean and Professor at the Interfaculty Initiative in Information Studies, University of Tokyo ©AOKI Noboru

Robot research is one of Japan’s areas of specialty. With 310,000 units, Japan lead’s the world for the number of industrial robots in operation (2013). The level of research and development of robots at universities and research institutes is also high. People point to influences such as the popular Japanese anime Astroboy, with its robot protagonist, as the backdrop to this. Based on these circumstances, the Abe administration has positioned the robot industry as one of the growth strategies in its economic strategy ‘Abenomics.’ In light of Japan’s declining birth rate and aging population, there are high hopes in particular for the foray of robots in the field of nursing care. On the other hand, however, common problems from other fields of Japanese industry can also be seen in ... [Read more]
