Pushing the limits of structured light, applied physicists report a new type of optical vortex beam that not only twists as it travels but also changes in different parts at different rates to create ...

When we think about highly sensitive medical testing, we often imagine a hospital laboratory filled with large instruments, trained technicians, and carefully controlled conditions. This is especially ...

Researchers have developed a light-driven method for creating tiny, high-energy “housane” molecules that are valuable for ...

The universe has a speed limit, and it's the speed of light. Nothing can travel faster than light — not even our best spacecraft — according to the laws of physics. So, what is the speed of light?

International Day of Light, proclaimed by UNESCO, highlights the fundamental role of light-based technologies in advancing science, innovation, and international cooperation. Among these technologies, ...
