The nanodevice produces an autonomous, stable current from evaporating saltwater by using heat and light to control the movement of ions and electrons.

Scientists used entangled X-ray photon pairs to produce ghost images of tiny samples, a proof of concept that could enable longer, lower-dose studies of delicate biological materials.

A team of researchers from Caltech and the University of Southern California has developed a microrobot for drug delivery within the body. According to its developers, the enzyme-powered microbubble ...

Scientists have taken a major step toward mimicking nature’s tiniest gateways by creating ultra-small pores that rival the dimensions of biological ion channels—just a few atoms wide. The breakthrough ...

The researchers turned to hydrogels, which are water-rich, jelly-like polymers that respond to temperature and chemicals. But instead of layering different materials or embedding electronics, they ...
