Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters and transforms inside real-world materials has long been treated as a black ...

While x-ray imaging has been used for medical diagnoses for more than a century, scientists have not been able to precisely describe how light moves within nontransparent scintillators – the key ...

A new liquid crystal device lets scientists control how light twists and behaves using voltage, making it possible to reshape light patterns without changing the physical structure of the device.
