The UK government is looking for a site on which to build the world's first prototype commercial fusion power plant, which it hopes to have operational by 2040. If you think sounds ambitious, you're right.

Borexino, a huge underground particle detector in Italy, has picked up a never-before-seen type of neutrino coming from the Sun. These neutrinos confirm a 90-year-old hypothesis and complete our picture of the fusion cycle of the Sun and other stars.

Lured by the prospect of nearly inexhaustible source of clean energy, scientists have been investigating nuclear fusion reactors for decades, but a new facility taking shape in southern France will provide them with their biggest proving ground yet.

"We are sidestepping all of the scientific challenges that have held fusion energy back for more than half a century," says the director of an Australian company whose hydrogen-boron fusion technology is working a billion times better than expected.

The structure that will house one of the largest and most ambitious energy experiments in history is now complete, with engineers working on the ITER Tokamak Building swinging their last pylon into place in readiness for the reactor's assembly stage.

Nuclear fusion could be an essentially unlimited energy source, but large eruptions in the plasma can damage reactors. But now physicists have found a way to prevent those large eruptions, by triggering lots of small ones through the injection of tiny pellets of beryllium.

Tokamak reactors and fusion stellarators are a couple of the experimental devices used in pursuit of nuclear fusion, but scientists at the University of Washington are taking a far less-frequented route known as a Z-pinch, with the early signs pointing to a cheaper and more efficient path forward.

ScienceAnother year is winding up, so it's time to look back at the scientific breakthroughs that excited us this year. From innovative new materials that open the door to more advanced tools and products, to discoveries that continue to push the borders of human knowledge, 2018 didn't fail to deliver.

Scientists working on the cutting edge Wendelstein 7-X nuclear fusion reactor are reporting the experimental device has achieved its highest energy density and the longest plasma discharge times for device of this type, marking another step forward in the quest for clean fusion power.
-
The day of clean, limitless energy from nuclear fusion has taken another step closer after China's Experimental Advanced Superconducting Tokamak (EAST) reached a core plasma temperature of over 100 million degrees Celsius (180 million degrees Fahrenheit).

The latest tidings from the Max Planck Institute for Plasma Physics, creators of the Wendelstein 7-X, are that a new record has been set for the fusion product – another significant step along the path to practical fusion power.
