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 exp...more
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 my...more

Genomic analysis of 370 Japanese Thoroughbred horses: the genetic background of why Thoroughbreds can run fast
Humans have been trying to improve Thoroughbreds by selectively breeding horses that can run fast. Each generation, a small number of males are selected to breed so that only these “elite” males can p...more
Gilles Ferrand was highlighted in a recent article of RIKEN RESEARCH "Supernova remnants used to probe how star explosion took shape"
RIKEN astrophysicists have bridged the gap between studies of supernova and those of their remnants by using the output of a supernova model as the input for a model of a supernova remnant. This appro...more
