Driving an electron spin vortex "Skyrmion" with a microcurrent

RIKEN and the National Institute for Materials Science (NIMS) have succeeded in forming a skyrmion crystal in which electron spin is aligned in a vortex shape in a microdevice using the helimagnet FeGe. The skyrmion crystal ...

Researchers create living human gut-on-a-chip

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University have created a gut-on-a-chip microdevice lined by living human cells that mimics the structure, physiology, and mechanics of the ...
