Scientists make detailed map of current between insulators

When scientists found electrical current flowing where it shouldn't be – at the place where two insulating materials meet– it set off a frenzy of research that turned up more weird properties and the hope of creating ...

A molecular light switch?... Just add water

A bit of stray moisture during an experiment tipped off scientists about the strange behavior of a complex oxide material they were studying—shedding light on its potential for improving chemical sensors, computing and ...
