Polarized light is one of the most powerful tools scientists have for peering inside matter, yet the way it twists, scatters ...

Scientists at the University of Oxford demonstrate an approach to interpreting how materials interact with polarized light, ...

New method identifies altermagnets by signatures from circularly polarized light, validated in MnTe, speeding discovery for ...

Two years ago, astronomers revealed the first-ever direct images of a black hole. Now, the collaboration behind the historic image has released a new version that shows the polarization of the light ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging ...

Researchers have uncovered hidden potential in metasurfaces and demonstrated optical devices that manipulate light's polarization state with an unprecedented degree of control. The research ...

The magnetic compass that birds use for orientation is affected by polarized light. That is the finding of researchers in Sweden, who studied zebra finches navigating a simple maze and found that the ...

Chris King is a histology technician at the National Institutes of Health, near Washington, D.C. He enjoys his work, which features heavy use of microscopy, but used to find it hard to explain what he ...

Single layers of transition metal dichalcogenides are two-dimensional (2D) direct-bandgap semiconductors with degenerate, but inequivalent, ‘valleys’ in the electronic structure that can be ...

Tech sees differently, and can fuse multiple types of data we can’t even perceive: lidar, IR, ultrasonic and so on. Metalenz, maker of highly compact “2D” cameras for advanced sensing, hopes to bring ...

Scientists developed a photodiode using a crystalline film composed of lead perovskite compounds with organic chiral molecules to detect circularly polarized light without a filter. It is expected as ...
