Researchers discover anti-laser masquerading as perfect absorber

Researchers at Duke University have discovered that a perfect absorber of electromagnetic waves they described in a 2017 paper can easily be tweaked into a sort of "time-reversed laser" known as a coherent perfect absorber ...

Lefty or righty molecules lend a hand to material structures

As below, so above. That seems to be an operating principle for molecules that start with a basic chirality—or "handed-ness"—and pass it on as they combine into larger structures.
