Fusion energy promises a future of clean, nearly limitless power, but building reactors that can survive the extreme ...

Scientists have long seen a puzzling pattern in tokamaks, the doughnut-shaped machines that could one day reliably generate electricity from fusing atoms. When plasma particles escape the core of the ...

The coming decades of space exploration hinge on a single, stubborn number: the 225 million kilometres between Earth and Mars. Chemical rockets, the workhorses of every space programme to date, take ...

Scientists saw a quark plowing through primordial plasma for the first time, offering a rare look at the first moments after ...

At the same time, a current of cold electrons travels toward the heated plasma from the opposite direction. When the two meet, the plasma develops filament-shaped instabilities that SLAC’s facilities ...

New simulations from Princeton Plasma Physics Laboratory suggest that deliberately engineering plasma rotation inside tokamak fusion reactors could dramatically reduce the heat loads that destroy ...

China breaks a historic barrier in nuclear fusion, bringing the dream of nearly infinite energy closer to reality.

The exhaust heat generated by a fusing plasma in a commercial-scale reactor may not be as damaging to the vessel's innards as once thought, according to new research about escaping plasma particles.

Chinese scientists break a historic barrier and achieve the highest plasma density in a nuclear fusion reactor.

Add Yahoo as a preferred source to see more of our stories on Google. Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time inside ...

Close-up measurements from NASA’s Parker Solar Probe are giving scientists an unprecedented look at how the solar wind gains ...
