Does unplugging your TV overnight actually save you electricity? Yes, but you might be able to get similar results with less effort. Here's how.

Julian is a contributor and former staff writer at CNET. He's covered a range of topics, such as tech, crypto travel, sports and commerce. His past work has appeared at print and online publications, ...

Researchers in China published a paper describing a theoretical model for photonic computing that used light particles instead of electrons for faster processing. The team developed “parallel optical ...

While it's no replacement for either computer, the new device is a powerful alternative for addressing some very practical challenges. Reading time 3 minutes In a world of ever-improving computing ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called skyrmions. These light vortices hold their shape even when disturbed, making them ...

The iBuyPower Element Pro is a superb all-AMD gaming PC. It doesn't totally skirt around inflated costs today, as its price has increased in recent months, but lots of memory and high capacity storage ...

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 ...

Cell phones have come a long way since they first made their public debut. From calling functionality to SMS to smartphone apps, your phone can now do almost everything a larger PC might. You can use ...

Just weeks after the IT and networking giant revealed that it had developed software designed to make the new networking paradigm work through networking application demos for classical use cases, ...

Researchers have been developing computers that deploy light (photons) rather than electricity to power storage and calculations. These light-based computers have the potential to be more energy ...

The preview of Gemini 2.5 Computer Use is only for developers at the moment, but it shows that the era of agentic AI is here. Jon covers artificial intelligence. He previously led CNET's home energy ...

Ultrathin structures that can bend, focus, or filter light, metasurfaces are reshaping how scientists think about optics. These engineered materials offer precise control over lights behavior, but ...
