New research identifies five distinct sleep subtypes, revealing links between brain patterns, behavior and health ...

This is a rare phenomenon known as cloud iridescence.

Nanyang Technological University, Singapore (NTU Singapore) scientists have used a classic optical phenomenon known as the “Poisson spot” to create stable patterns of light called “optical skyrmions”.

Flexible, and easy-to-use Python diffraction simulator that focuses on visualizing physical optics phenomena. The simulator uses mainly scalar diffraction techniques for light propagation, provides a ...

A light-sensitive crystal is opening the door to a new era of “light-written” technology. Arsenic trisulfide can be reshaped and permanently altered using simple light, creating ultra-fine optical ...

Researchers developed a holographic data storage approach that stores and retrieves information in three dimensions by combining the amplitude, phase and polarization properties of light.Xiaodi Tan, ...

Abstract: Photolithography has a resolution limit of the incident wavelength that is generated by the diffraction of light. Surface plasmon (SP) is a recently proposed nanolithography technology that ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is found in conventional systems. In conventional antiferromagnets, the ...

A pulse of light sets the tempo in the material. Atoms in a crystalline sheet just a few atoms thick begin to move—not randomly, but in a coordinated rhythm, twisting and untwisting in sync like ...

Is it possible to 3d print a diffraction pattern? Trump’s supporters are starting to turn on him as his approval falls Dentist calls police on Aussie mom during ...
