Red blood cells are essential for oxygen transport and immune function in the human body. When these cells become abnormally shaped, they can indicate serious health conditions, including diabetes, ...

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

Researchers at Tsinghua University have created a rapid, label-free method using polarized light detection to identify and ...

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 ...

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

Forget LEDs, researchers from the University of Michigan have developed a new type of incandescent light bulb. The device is capable of emitting elliptically polarized light, described as "twisted" ...

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 ...

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 ...

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 ...
