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

Altermagnets are a newly recognized class of antiferromagnets whose magnetic structure behaves very differently from what is ...

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 ...

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

Motors and gear trains with micrometer dimensions and powered by light are fabricated using semiconductor lithography and ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

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 ...

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 ...

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 ...
