Ultrafast optical technique reveals how electrical double layers form in liquids
Charged surfaces in contact with liquids—such as biological cell walls or battery electrodes—attract oppositely charged ions from the liquid. This creates two distinct charged regions: the surface itself and a counter-charged region in the liquid: the so-called electrical double layer. While pivotal to energy storage devices, the speed of its formation has remained elusive.

Multi-spacecraft radio observations trace the heliospheric magnetic field
Solar flares accelerate energetic electrons that escape into interplanetary space, guided by the Parker spiral magnetic field, and are responsible for the generation of the interplanetary Type III solar radio bursts. With multiple spacecraft now in orbit around the sun, we are in a unique position of observing the propagation of radio emission through the heliosphere from multiple vantage points.
