Scientists have developed a new kind of wearable sensor that can detect signs of eye disease—without drawing blood or using expensive lab equipment. Instead, it’s a soft, non-invasive patch placed ...

The Spanish National Cancer Research Centre (CNIO) and the Spanish National Research Council (CSIC) are part of the international consortium NanoBright, which has developed this new tool. The probe ...

Scientists have cracked a century-old physics mystery by detecting magnetic signals in non-magnetic metals using only light and a revamped laser technique. Previously undetectable, these faint ...

For over a century, scientists have known that electric currents bend in a magnetic field—a phenomenon known as the Hall effect. In magnetic materials like iron, this effect is strong and well ...

Forward-looking: Researchers at the Beijing Institute of Technology have developed a microphone that doesn't detect air vibrations like traditional models. Instead, it captures light reflected from ...

Researchers have created a microphone that listens with light instead of sound. Unlike traditional microphones, this visual microphone captures tiny vibrations on the surfaces of objects caused by ...
