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 ...

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 ...
