The cheery-sounding program sought particularly to understand the impact of strontium 90, an unstable, radioactive version of a naturally occurring element which threatened to riddle people and animals with cancer. » More …

Physicists write with light, turn crystal into an electrical circuit

artistic depiction of writing with lightWashington State University physicists have found a way to write an electrical circuit into a crystal, opening up the possibility of transparent, three-dimensional electronics that, like an Etch A Sketch, can be erased and reconfigured.

The work, to appear in the on-line journal Scientific Reports, serves as a proof of concept for a phenomenon that WSU researchers first discovered by accident four years ago. » More …
