Physicists in the Netherlands have built a heat engine that might be the tiniest ever created. Based on “piezoresistive” silicon, and smaller than a typical biological cell, the engine could find ...

A tiny, particle-sized engine that runs at temperatures approaching the innermost core of the Sun could open a window into the smallest extremes of thermodynamics. By levitating a single particle of ...

In and out: An illustration of the quantum engine as a piston, showing the piston compressed when the particles in the gas exist as bosonic molecules and expanded when they are individual fermionic ...

For the first time, a quantum engine has outperformed its traditional equivalent, without any special tweaks to its environment. The device harnesses the weird physics of very small objects to produce ...

Engineers have built a modern Stirling engine that quietly turns the cold of outer space into steady mechanical power, using the night sky as a heat sink instead of a fuel tank. By radiating heat away ...

El Niño-Southern Oscillation (ENSO) is the strongest signal in interannual climate variation. El Niño increases the precipitation over the equatorial central-eastern Pacific, which releases more ...
