Blinking neurons give thoughts away
(PhysOrg.com) -- Electrical currents are invisible to the naked eye - at least they are when they flow through metal cables. In nerve cells, however, scientists are able to make electrical signals visible. ...

New material could efficiently power tiny generators
(PhysOrg.com) -- To power a very small device like a pacemaker or a transistor, you need an even smaller generator. The components that operate the generator are smaller yet, and the efficiency of those foundational components ...

Novel electric signals in plants
Using ion-selective micro-electrodes electrical signals in plants moving from leaf to leaf could be measured. The speed of the signals spreading as voltage changes over cell membranes ranged from 5 to 10 cm ...
