Two main acceleration mechanisms in the auroral acceleration region are electric potential and Alfvénic acceleration but associated energy dynamics are not completely resolved. Here, the authors show that Alfvén waves power the Earth’s auroral arc through a static potential drop in the auroral acceleration region.

KRAS is an oncogene that switches between a GDP-bound inactive state and a GTP-bound active state. Recently developed KRAS G12C inhibitors are specific to the GDP-bound inactive state. Here, the authors develop a class of covalent KRAS G12C inhibitors capable of targeting both states for the treatment of KRAS-driven cancer.
