Riken is a large scientific research institute in Japan. Founded in 1917, it now has about 3,000 scientists on seven campuses across Japan, including the main site at Wakō, Saitama Prefecture, just outside Tokyo. Riken is a Designated National Research and Development Institute, and was formerly an Independent Administrative Institution. "Riken" is a contraction of the formal name Rikagaku Kenkyūjo, and its full name in Japanese is Kokuritsu Kenkyū Kaihatsu Hōjin Rikagaku Kenkyūsho and in English is the Institute of Physical and Chemical Research. Riken conducts research in many areas of science, including physics, chemistry, biology, genomics, medical science, engineering, high-performance computing and computational science, and ranging from basic research to practical applications with 485 partners worldwide. It is almost entirely funded by the Japanese government, and its annual budget is about ¥88 billion (US$790 million).

Mathematical theory predicts self-organized learning in real neurons

“An international collaboration between researchers at the RIKEN Center for Brain Science (CBS) in Japan, the University of Tokyo, and University College London has demonstrated that self-organization of neurons as they “learn” follows a mathematical theory called the free energy …

Forging a dream material with semiconductor quantum dots

“Researchers from the RIKEN Center for Emergent Matter Science and collaborators have succeeded in creating a “superlattice” of semiconductor quantum dots that can behave like a metal, potentially imparting exciting new properties to this popular class of materials. Semiconducting colloidal …

Gravitational waves could indicate transition to strange quark matter

“Gravitational waves could reveal whether the quark soup that existed in the early Universe is created in neutron-star mergers Telltale signatures in gravitational-wave signals from merging neutron stars should reveal what happens to matter at the extreme pressures generated during …

Modeling longer-lived holes in silicon quantum dots

“The development of quantum computers will benefit from a new model that models spin in tiny silicon dots A theoretical model developed by three RIKEN physicists for optimizing semiconductor nanodevices will be helpful for scaling up quantum hardware1. An electron …

Quantum ‘magic’ could help explain the origin of spacetime

“Physicists relate the quantum property of ‘magic’ to the chaotic nature of black holes for the first time A quantum property dubbed ‘magic’ could be the key to explaining how space and time emerged, a new mathematical analysis by three …

Stripes within crystals hint at behavior of electrons in quantum systems

“A hidden pattern of electrons could provide clues to exotic quantum behavior Hidden stripes in a crystal could help scientists understand the mysterious behavior of electrons in certain quantum systems, including high-temperature superconductors, an unexpected discovery by RIKEN physicists suggests1 …

A robust self-healing polymer made from a common chemical

“Material scientists at RIKEN have created a self-healing polymer by using an off-the-shelf compound for the first time1. The strategy they used is promising for improving the durability and minimizing the environmental impact of various commercial polymers for a wide …

Robobug: a rechargeable, remote-controllable cyborg cockroach

“An international team led by researchers at the RIKEN Cluster for Pioneering Research (CPR) has engineered a system for creating remote controlled cyborg cockroaches, equipped with a tiny wireless control module that is powered by a rechargeable battery attached to …

It takes three to tangle: long-range quantum entanglement needs three-way interaction

“A theoretical study shows that long-range entanglement can indeed survive at temperatures above absolute zero, if the correct conditions are met. Quantum computing has been earmarked as the next revolutionary step in computing. However current systems are only practically stable …

Wormholes help resolve black hole information paradox

“A mathematical analysis helps illuminate the puzzle over how information escapes from a black hole A RIKEN physicist and two colleagues have found that a wormhole—a bridge connecting distant regions of the Universe—helps to shed light on the …
