Centennial RIKEN Research


???This Spring we’ve put together a special centennial issue of RIKEN Research ???

New metalloenzyme system selectively targets cancer cells


Specific targeting of cancer cells and onsite drug synthesis has been achieved using a new artificial metalloenzyme delivery system.

RIKEN Research Fall Issue


Fall is here, and with it comes the latest issue of RIKEN Research. This issue covers tactile learning during sleep, supercomputers and simulations, solar cells, fly olfaction, tumor vaccines, and more

Physiological origami and proper body development in flies


Genetics and mechanical origami in the fly embryo helps proper body development by fighting off “noisy” fluctuations is the environment.

Mutation links bipolar disorder to mitochondrial disease


ANT1 mutations found in bipolar disease that affect mitochondria lead to hyperexcitable serotonergic neuronal activity in the brain.
