I follow the solar flares and try to predict optimal aurora viewing times, so this is relevant to my interests.
"The study, published online June 7 in the journal Nature Communications, concludes a decades-long quest to demonstrate experimentally the physical mechanisms for the acceleration of electrons by Alfven waves under conditions corresponding to Earth's auroral magnetosphere."
