Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns.

In 2025, the Earth entered a new reality: the planet reached the first of six progressively worse ‘climate tipping points,’ which scientists say pose catastrophic risk to billions of people. The ...

The use of artificial intelligence (AI) systems, such as the models underpinning the functioning of ChatGPT and various other online platforms, has grown exponentially over the past few years. Current ...

Delay lines bridge abstract timing concepts with hands-on engineering solutions in communications, signal conditioning, and ...

The particles in a metal are held together by strong metallic bonds. The particles are close together and in a regular arrangement. Metals atoms have loose electrons in the outer shells, which form a ...
