The main nutritional difference between skim milk and light milk, apart from the fat content, is the energy content. Skim milk provides about whereas light milk provides about .

Polarization of photons plays a key role in quantum optics and light-matter interactions, however, it is difficult to control in nanostructures. Here scientists reveal polarization control of ...

Light is all around us, essential for one of our primary senses (sight) as well as life on Earth itself. It underpins many ...

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of physics.
