Blue light is a high-energy light that the eyes absorb from computers, smartphones, LED lights, and fluorescent lights. The sun is the biggest source of blue light. On a sunny day, it's 100,000 ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons. This ...

This high-energy light radiates from our smartphones, computer screens, tablets, LED lighting, and even the sun—which remains by far our most significant source of blue light exposure ...

Blue light has acquired a dubious reputation in recent years, frequently blamed for everything from disrupted sleep patterns to digital eye strain. This high-energy light, emitted abundantly by ...

This cross-journal collection born in collaboration between Communications Physics, Nature Communications and Scientific Reports explores recent progress in high-energy light sources, from from ...

Scientists have detected the highest-energy "ghost particle" ever seen. The particle, a type of neutrino, arrived at Earth at nearly the speed of light and with 30 times the energy of the previous ...

A faint radio glow reveals a million-light-year halo enveloping one of the earliest galaxy clusters, hinting that energetic ...

Blue light is a high-energy light that the eyes absorb from computers, smartphones, LED lights, and fluorescent lights. The sun is the biggest source of blue light. On a sunny day, it's 100,000 ...

The continuous development of bright, stable and highly coherent high-energy light sources is a propellant to the fields of material science, biomedical imaging, ultrafast spectroscopy, and ...
