Imagine shining a flashlight into a material and watching the light bend backward—or in an entirely unexpected direction—as if defying the law of physics. This phenomenon, known as negative refraction ...

Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new ...

A new light-based breakthrough could help quantum computers finally scale up. Stanford researchers created miniature optical cavities that efficiently collect light from individual atoms, allowing ...

Today we're looking at Atomic Force Microscopy! I built a "macro-AFM" to demonstrate the principles of an atomic force ...

Discover how to transform a basic webcam into a powerful DIY microscope using simple materials. In this step-by-step tutorial, you'll learn how to build a functional microscope stand from cardboard, ...

Scientists have shattered the diffraction limit, using continuous-wave lasers to resolve images at 0.1 nanometers.

On Christmas Day 2021, alongside other astronomers, I watched the James Webb Space Telescope (JWST) launch from French Guiana and begin its month-long journey to its destination, 1.5 million ...
