Discovery of a Superconductive Material that Defies Conventional Wisdom

Discovery of a Superconductive Material that Defies Conventional Wisdom

Research Center and Director of the Materials Research Center for Element Strategy defied conventional wisdom when he discovered an iron-based high-temperature superconductor in 2008. This discovery helped accelerate research into new superconductive materials worldwide, and more than 70 new superconductors have been discovered since. Hosono's paper has been cited more than 5000 times by scientists around the world, and in 2013 he was selected as a Thomson Reuters Citation Laureate. Tokyo Tech's Materials Research Center for Element Strategy leads the world in materials science research.

Researching the Most Basic of Cell Functions: Autophagy

Researching the Most Basic of Cell Functions: Autophagy

Autophagy is the process by which cells break down their own proteins and other substances. The mechanism helps maintain healthy cells, providing nourishment to stave off starvation and eliminating unnecessary proteins and organelles, which are large structures within cells. Autophagy is involved in various physiological functions such as inhibiting the growth of cancer cells and slowing down the aging process. Honorary Professor Yoshinori Ohsumi of the Frontier Research Center was the first person in the world to confirm autophagy with the naked eye. He has elucidated the mechanism of autophagy and the responsible genes. Professor Ohsumi's contributions to the field of bioscience have received wide acclaim. He has been honored with the Fujihara Award, the Japan Academy Prize, and the Asahi Prize, and in 2012 he won the Kyoto Prize for Basic Sciences. In 2013, he was selected as a Thomson Reuters Citation Laureate.

TSUBAME - The world's most energy-efficient supercomputer

TSUBAME - The world's most energy-efficient supercomputer

TSUBAME is the designation for a series of high-performance supercomputers developed by Professor Satoshi Matsuoka and the Global Scientific Information and Computing Center to support advanced research and education at Tokyo Institute of Technology (Tokyo Tech). TSUBAME 2.0, which began operating in 2010, was ranked fourth in the world for supercomputer performance in November 2010. TSUBAME 2.5, upgraded from TSUBAME 2.0 in 2013, has a theoretical operating performance of 17.1 petaflops1 at single-precision floating point, overtaking the K Computer which was the fastest supercomputer (11.4 petaflops) in Japan at the time. TSUBAME-KFC, the prototype for TSUBAME 3.0 featuring an oil cooling system and dramatically reduced energy consumption, was ranked the world's most energy-efficient supercomputer by Green500 two times in a row both in November 2013 and June 2014. TSUBAME 3.0, which will offer even greater performance enhancements, is scheduled to begin operating in 2016, continuing the evolution of TSUBAME.


1. Petaflops:
A petaflop equals one quadrillion floating point (real number) operations per second.

An Environmental Technology Research Building Clad in Solar Panels

An Environmental Technology Research Building Clad in Solar Panels

The Environmental Energy Innovation (EEI) Building at Tokyo Tech's Ookayama Campus was completed in 2012. The roof and the south and west faces are covered with a total of 4570 solar panels. With the green power provided by the solar panels and a fuel cell system that makes up for any energy production shortfalls, the building is nearly energy self-sufficient, a globally unprecedented feat for a research center. The smart grid management system "Ene-Swallow" allows for collection and visualization of energy information on the building while maintaining a balance between the supply and demand for energy. CO2 emissions have been cut by approximately 60 percent, and its center is a leader in environmental energy technologies research. The EEI Building also plays a role in local disaster preparedness in the community against earthquakes and other emergencies.

Solving the Mystery of the Earth and Life at the Earth-Life Science Institute (ELSI)

Solving the Mystery of the Earth and Life at the Earth-Life Science Institute (ELSI)

The Earth-Life Science Institute (ELSI) was established in 2012 through the Ministry of Education, Culture, Sports, Science and Technology (MEXT)'s World Premier International Research Center Initiatives (WPI) program with the aim of becoming a globally competitive center to elucidate some of the most fundamental mysteries faced by humanity: how the Earth was formed and how its early environment allowed for the rise of initial life and its subsequent evolution to complex forms of life. ELSI has an ideal research environment and has attracted top quality researchers from around the world by building upon an international cooperative framework with institutions both in Japan and overseas. ELSI also has three satellite centers: two in the United States, one at the Institute for Advanced Study and one at Harvard University; and, one at Ehime University in Japan. Recently, ELSI researchers have discovered that hydrocarbons, the basic building blocks of life, are synthesized in hot spring environments through inorganic chemical reactions, thereby providing more clues to the mechanism behind the origin of life on Earth. ELSI continues to produce other extraordinary results, such as the identification of hydrogen in the Earth's deep mantle. This new discovery tells us that a significant amount of water was present when the Earth was formed and gives us a glimpse into the history of our planet's formation.
