Howrah Bridge lighting gets a Rs 22.35-crore upgrade with 3,825 luminaires, synchronised shows and a dedicated public mobile ...

A recent study shows that sleeping with even small amounts of light may disrupt sleep and increase the risk of heart problems ...

Light is traditionally described by properties such as wavelength, amplitude, phase and polarization. Advances in optics have ...

A laser does not always need a perfectly repeating pattern to produce a clean beam. Researchers at the University of Illinois ...

The human eye can perceive subtle polarization patterns in light, revealing structural features of the retina without invasive imaging. We identified a visual phenomenon in which structured light ...

WASHINGTON -- The annual Memorial Day parade ambled down Constitution Avenue as Michael Ward and his family, visiting from Ohio, stopped in front of The Ellipse and peered through black fencing at ...

Within this context, architects continue to expand their practice into the realm of product and industrial design, engaging with questions of material performance, fabrication processes, and domestic ...

Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor ...

New research from the Mork Family Department of Chemical Engineering and Materials Science at USC Viterbi shows how the organization of electrons can reshape how a material responds to light – opening ...

A network of torons, self-organizing defects in liquid crystals whose internal structure enables the generation of laser light carrying orbital angular momentum. Credit: Marcin Muszyński, Faculty of ...

Optical vortices—light beams carrying orbital angular momentum (OAM)—are characterized by helical wavefronts and phase singularities. While they have been widely studied in recent decades, two ...
