They have made what’s believed to be the first polariton laser that is fueled by electrical current as opposed to light, and also works at room temperature, rather than way below zero. (more…)

The finding shows that the number of innocent people sentenced to death is more than twice the number of inmates exonerated and freed by legal action, according to a study published today in the Proceedings of the National Academy of Sciences. (more…)
