High-precision magnetic sensors rely on uniform light to polarize atomic spins, yet most laser beams naturally deliver energy unevenly, limiting ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.

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

It has long been considered common sense that a single device performs only one function. Just as tuning a radio to a ...

In mid-December 2025, an image (archived) circulated online purportedly showing U.S. President Donald Trump using a walker as a mobility aid. Keith Edwards, a Democratic political strategist, posted ...

In January, a team led by Jim Schuck, professor of mechanical engineering at Columbia Engineering, developed a method for creating entangled photon pairs, a critical component of emerging quantum ...

To better understand which social media platforms Americans use, Pew Research Center surveyed 5,022 U.S. adults from Feb. 5 to June 18, 2025. SSRS conducted this National Public Opinion Reference ...

Emerging research suggests that the more you use AI, the more it may negatively affect your critical thinking skills. But it depends on the tasks you use it for and how you use it. Share on Pinterest ...

A new single-layer chiral metasurface detects circularly polarized light efficiently, offering a compact, high-performance alternative to bulky optical systems. (Nanowerk News) Detecting circularly ...

Business leaders and employees make dozens of communication choices each day, from what to say to how to say it. In a recent research paper, we (three academics) focus on one such small ...
