For decades, nuclear fusion has been viewed as the ultimate energy source—clean, powerful, and practically limitless. Most approaches to fusion involve enormous machines designed to squeeze plasma ...

Neutrons characteristic of nuclear fusion have been produced sustainably inside a device that is small enough to fit on a tabletop. Yue Zhang at the University of Washington and colleagues observed ...

The Nature Index tracks primary research articles from 145 natural-science and health-science journals, chosen based on reputation by an independent group of researchers. The Nature Index provides ...

The new experiment, published in Nature, uses a compact, room-temperature fusion reactor. It doesn’t aim for large-scale energy production—yet. Instead, it focuses on a way to improve the fusion ...
