A series of quantum physics experiments and theoretical papers now suggest that heat can flow spontaneously from a cold object to a hot one, provided the right quantum conditions are in place. This ...

A team of U.S. scientists has made a surprising discovery that could help bring fusion energy, a long-hoped-for clean energy source, closer to reality. In a recent experiment at the University of ...

With the world set to blow past 1.5°C of warming, researchers are increasingly studying possible methods of cooling the planet by modifying the atmosphere or the oceans. More geoengineering research ...
