Inviting researchers from around the world, everyone aims at positively getting out of stereotypes in their research and everyday life.
If I say, "Raise your hand if you have never used a computer", and if anyone raises his/her hand, this is an incredible person. From cellular phones to rice-cookers, every electric appliance uses a computer. A vehicle may look like a chunk of machinery, but actually half of it is made of electrical parts. I am quite sure that no reader of this column can raise his/her hand. Now then, if a computer is so important in our modern society, what is the ultimate computer?
This definition may vary. For example, a computer that hardly uses electricity is environmentally-friendly. If it can also generate solar power, there is nothing more to say. Some seek to realize an impossible calculation with a computer. An American scientist that I know is studying how much improvement can be expected if the entire energy of the universe is used to improve the performance of computers. You and I both will have to use all of our efforts. This may sound nonsense, but yes, it may be an incredible computer. The major research area of my group is quantum computers that use atoms for calculation. These are incredible computers, more exciting as a scientific theme rather than practical, of an ultimately small world of quantum mechanics. It is similar to developing a space shuttle when everyone else is trying to improve the performance of cars, seeking to create an ultimate vehicle.
Come to think of it, progress in research is somewhat similar to human growth. There is no definition of an incredible person, but incredible people do exist, and they are somehow different from other people. By getting out of stereotypes and be full of ideas in our research, I am trying to realize the "half learning, half teaching" philosophy of Yukichi Fukuzawa in our laboratory so that both students and myself can grow uniquely. Knowledge of physics and mathematics is necessary, but more than that, you should have scientific curiosity and viewpoints that are different from other people.
However, as long as I work for Keio University, which emphasizes on jitsugaku (practical learning), I feel that we should also have a realistic dream. One thing I recently came up with is "no overtime work computer". When the performance of the computer improves and becomes 2 to 3 times faster, can people get to go home early? The answer is no, and I hear that the amount of computer work increases. Improvement of network technologies resulted in having to work at home after work. Why don't we get rid of this? If you have any good ideas, let's work on it together. I hope to hear from you.
Prof. Kohei Itoh, Faculty of Science and Technology
Prof. Itoh joined Keio from Yochisha Elementary School, and advanced to Futsubu School, Keio Senior High School and to the Faculty of Science and Technology at Keio University. He graduated in 1989. He obtained a Master's degree at University of California, Berkley in 1992, and a Ph.D. in 1994. The following year, he became Research Assistant at the Faculty of Science and Technology of Keio University. He then served as Assistant Professor and Associate Professor before becoming Professor in 2007. During this time, he also served in the Executive Board Committee of the Physical Society of Japan, and in the Executive Board Committee of the Institute of Pure and Applied Physics. His major research area is semiconductor physics. He was awarded the Japan IBM Science Award in 2006 for his research in creative electronics.Student's Voice
With a professional mind
Electronic appliances that surround us such as computers and cellular phones use semiconductors. We are one of the few laboratories in the world to focus on defining the physical phenomenon of silicon, king of semiconductors, with a new approach using isotopic material. Although it is thought that the semiconductor as a research theme has been exhausted, the material still holds unexplained features. Research is based on the autonomy of the individual, and if you work hard, you have a chance to lead the world creatively. Most of our research is related to maintaining our equipment, but because we put in great efforts, it is a real pleasure when we produce positive results. Prof. Itoh is enthusiastic about inviting students, researchers and professors from around the world, and because we conduct experiments and have discussions with them, communicating in English is a must and we also have many opportunities for cultural exchange. Students have many opportunities to expand their research activities beyond the campus, and our research environment is really appealing for students with a professional mind.

At the productronica trade fair in Munich this November, the Fraunhofer Institute for Laser Technology ILT will be presenting Laser-Based Tape-Automated Bonding, LaserTAB for short. The experts from Aachen will be demonstrating how new battery cells and power electronics can be micro-welded more efficiently and precisely than ever before thanks to new optics and robot support.
Fraunhofer ILT from Aachen relies on a clever combination of robotics and a laser scanner with new optics as well as process monitoring, which it has developed...
Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.
A warming planet
Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
