In a surprising twist, researchers have identified crystals that are symmetrical but nevertheless absorb light as if they were chiral (Science 2025, DOI: 10.1126/science.adr5478). The discovery ...

Many seafaring cultures crossed the sea by observing the sky. The sun and the stars can be used to find the actual position as to set the ship's course. Using the height above the horizon of certain ...

The quantum behavior of atomic vibrations excited in a crystal using light pulses has much to do with the polarization of the pulses, say materials scientists. The findings from their latest study ...

Optical microscope image of a representative crystal that possesses centrosymmetry, yet shows differential absorption of circularly polarized light. The crystal is made of lithium, cobalt, selenium ...

Using a reverse-image search via Google Lens (archive), Snopes determined that Pixels, a photography and art hosting website, published the original photograph. Titled, "Polarized light micrograph of ...

“Everything is born out of nothing. All you do is shine a light, and this whole world of time crystals emerges,” said University of Colorado Boulder physicist Ivan Smalyukh. In a field where most ...

Although caffeine is the most widely used drug in the world, many people may not know what the substance actually looks like. In April 2024, a post on Reddit (archive) claimed to show "Caffeine ...

Robots and cameras of the future could be made of liquid crystals, thanks to a new discovery that significantly expands the potential of the chemicals already common in computer displays and digital ...

To the naked eye, solids may appear perfectly still, but in reality, their constituent atoms and molecules are anything but. They rotate and vibrate, respectively defining the so-called "rotational" ...
