People are buying helmets, face masks, vests and beds that emit long-wavelength light. Beneath the hype, there is some ...

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Decoding cellular signals has long been a cornerstone of biomedical research, offering insights into how cells communicate and respond to environmental changes. This knowledge is vital for diagnosing ...

Physicists have created a new and long-lasting magnetic state in a material, using only light. The results provide a new way to control and switch antiferromagnetic materials, which are of interest ...

Compact fluorescent light bulbs (CFL) were born during the oil crisis that began in 1973. They became popular by the 2010s, when concerns about energy efficiency as a way to combat climate change rose ...

Researchers have discovered that perovskite crystals can rapidly and reversibly change shape when exposed to light, revealing ...

Researchers at the University of California, Los Angeles (UCLA) have unveiled a new optical technology that enables precise focusing of light—only in one direction. This novel unidirectional focusing ...

Proposed methods of removing toxic ‘forever chemicals’ from water have either only trapped the chemicals or broken them down. A new study has demonstrated a method that does both – quickly and cheaply ...
