Large language models (LLMs) like OpenAI's ChatGPT, Anthropic's Claude and Google Gemini are increasingly being used to help robots perform tasks, but what if LLMs could be exploited to turn helpful robots into harmful robots?

A small stream of liquid flows quietly in midair, horizontally, as if inside an invisible tube. Nothing touches it. About 5 centimeters (2 inches) away, a cylinder lined with hundreds of tiny speakers surrounds the stream, ...

Humans are usually remarkably good at recognizing objects, even under poor conditions. Artificial vision systems, by contrast, reach their limits more quickly. Researchers at the Hertie Institute for Clinical Brain Research ...

The twin earthquakes that struck Venezuela on June 24, 2026, collapsing buildings across northern Venezuela, from Yaracuy state to Caracas, have revived a question that follows every major quake: Why do some buildings fall ...

Research by Columbia University faculty in the Arts and Sciences and the School of Engineering and Applied Science has revealed a new insight that challenges long-held assumptions about the fundamental chemistry of lithium-ion ...

Smart glasses need compact, efficient displays that can produce detailed images without drawing too much power. Laser beam scanning is one approach to meeting these requirements. Rather than using a fixed array of pixels, ...

As artificial intelligence moves increasingly toward edge devices, researchers are exploring electronic components that can combine memory and information processing. Memristive and synaptic devices are of particular interest ...
