Recent physics studies have found that light can sometimes flow in unexpected ways, behaving like a so-called "superfluid." Superfluids, such as ultracold atomic gases or helium-4 below specific ...

In some children with myopia, repeated low-level red-light therapy for at least 1 year was associated with reduced cone density near the fovea and other subtle retinal abnormalities. A retrospective ...

Researchers theoretically proposed the existence of density limit for hole boring by laser light on matter. They derived the maximum plasma density as a function of laser intensity, where hole boring ...
