Plasma protection for rice crops

Diseased rice seeds treated with atmospheric plasma show significant improvement and growth, offering a potential tool to protect rice crops from fungus and blight. A team from Tohoku University in Japan found that immersing ...

Fusion reactor designs with 'long legs' show promise

Magnetic fusion is all about managing the interface between hot plasma and ordinary materials. The strong magnetic field in a tokamak—the vessel used in this fusion approach—is a very effective insulator; it is able to ...

A new look at the galaxy-shaping power of black holes

Data from a now-defunct X-ray satellite is providing new insights into the complex tug-of-war between galaxies, the hot plasma that surrounds them, and the giant black holes that lurk in their centres.

Controlling ITER with fuelers, ticklers, and terminators

When it's up and running, the ITER fusion reactor will be very big and very hot, with more than 800 cubic meters of hydrogen plasma reaching 170 million degrees centigrade. The systems that fuel and control it, on the other ...

Origin of 'theta aurora'—long-standing space mystery—revealed

Auroras are the most visible manifestation of the sun's effect on Earth, but many aspects of these spectacular displays are still poorly understood. Thanks to the joint European Space Agency and NASA's Cluster mission combined ...

Hot lithium vapors shield fusion facility walls

Recent experiments provide the first assessment of the toughness of a novel lithium coating in the face of intense bombardment by very hot plasma in the divertor region of fusion devices. The results show that this coating ...
