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

Why (mouse) mothers take risks to protect their infants


The calcitonin receptor and its ligand amylin act in the brain to motivate mouse mothers to protect their pups, even in risky/dangerous situations.

Omics Omics Omics: Analysis predicts ovarian cancer-treating drug


Multi-omics analysis prediction: drugs that inhibit Ras signaling will help prevent tumor formation in serous ovarian cancer.

Consciousness, brain connections, and the claustrum


Research shows that the claustrum acts as a ‘consciousness conductor’ that synchronizes and connects areas within the mouse brain.
