Memristors with a twist: Quasi-liquid soft matter foreshadows biocompatible electronics and flexible robots
In some circles, memristors (from "memory resistor," as coined by Leon Chua in a 1971 paper outlining memristive theory) are all the rage – and for good reason: As circuit elements which "remember" the ...

Scientists discover new hitch to link nerve cell motors to their cargo
from the blink of an eye to running a marathon—nerve cells transmit signals to muscle cells. To do that, nerve cells rely on tiny molecular motors to transport chemical messengers (neurotransmitters) that excite muscles ...

Parkinson's disease may be caused by microtubule, rather than mitochondrial complex I, dysfunction
Patients with Parkinson's disease (PD) suffer a specific loss of dopaminergic neurons from the midbrain region that controls motor function. The exact mechanism of this selective neurodegeneration is unclear, ...
