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

Electrolithoautotrophs


Learn what electrolithoautotrophs are and how the scientists proved that A. ferrooxidans can use electric potential to fuel growth.

Simple but revolutionary modular organoids

A new way to construct complex 3D organoids without using elaborate techniques! The trick using modular cubes with hydrogel layers.

Flies use fecal deposits as pheromones


Bioluminescence imaging of fly brains reveals neurons sensitive to fly poo laced with pheromones (you can see the fecal “landmark” in the dotted circle). Need we say more?

Melatonin in mice, circadian rhythms, and daily torpor


A new breed of lab mouse allows the study of naturally occurring melatonin. These mice will adjust better to jetlag than regular lab mice and experience daily torpor.
