Tracking down the origin of photons in gamma-ray bursts, article on RIKEN Research by Drs. S. Nagataki & D. Warren


The photons released by long gamma-ray bursts - the most powerful electromagnetic phenomena in the Universe - originate in the photosphere, the visible portion of the ‘relativistic jet’ emitted by exploding stars, according to simulations by RIKEN researchers.

The shape of circadian rhythm, article on RIKEN Research by Drs. S. Gibo & G. Kurosawa


The waveforms of circadian cycles in bacteria, flies and mammals become increasingly jagged as the temperature rises, two RIKEN researchers have predicted. This finding is a step toward solving the mystery of how circadian rhythms remain consistent under changing conditions.

Hot Topic

Short Report of Robotics Workshop held at IIAS in Kyoto


Robotics Workshop organized by RIKEN was held on Sep. 12-13 at a beautiful campus of the International Institute for Advanced Studies (IIAS) in Kyoto.

Gilles Ferrand (ABBL/iTHEMS) and Tetsuo Hatsuda (iTHEMS) attended the workshop: Gilles gave a talk on "Virtual Reality and Robotics" and also conducted VR demo during the coffee breaks with Tetsuo as his assistant. All the 35 talks during the two days were "graphically recorded" in real time as the one attached for the Gilles case. (Some illustration company in Kyoto came to do this.) Although each coffee break was short (5-10 min), altogether six people could enjoy the VR of the supernova remnant. It was an interesting experience for us to interact with robotics engineers who have rather different way of thinking from the researchers in basic sciences.

Workshop on Virtual Reality[Session 1]

October 7 at 13:00 - 16:00, 2019

Gilles Ferrand and Don Warren will run a workshop on using virtual reality (VR) for data visualization and research. Anyone from any RIKEN campus, and any field of study, is welcome. We want to build a cross-disciplinary group of people with a shared interest in VR, and to apply this tool to a broad range of data types and topics.

Please check the workshop website for up-to-date information !

Venue: #132, 1F, Main Research Building, RIKEN

Researches & Researchers

Dr. Ade Irma Suriajaya thumbnail

Knowledge that spreads from many encounters - Dr. Ade Irma Suriajaya


Dr. Ade Irma Suriajaya (Chacha) is originally from Indonesia and shifted her field from aeronautical engineering to mathematics. We will introduce the beauty of mathematics, which Chacha has been eager to learn, going so far as to move from Indonesia to China and then onto Japan.
