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 ...

Is it wizardry? Physicists at the University of Konstanz have succeeded in changing the properties of a material in a non-thermal way with the help of light and magnons. The new process is not only ...

A new holographic storage technique uses light in three dimensions to dramatically increase how much data can be stored. It encodes information throughout a material using amplitude, phase, and ...

Machine-learning models identify relationships in a data set (called the training data set) and use this training to perform operations on data that the model has not encountered before. This could ...

In this video, I explore creating a doodle using a glow-in-the-dark ink pen under UV light. The lines appear invisible until the light reveals them, making for a fun and experimental drawing session.
