The primary causes of dramatic variations in volcanic flux and composition along strike in subduction zones remain largely unknown. Here we use a promising new approach to show that along-strike volcanic variability in the Quaternary Cascades Arc is primarily due to variations in the flux of basalt into the base of the crust, rather than crustal magma storage.
Given the recent growing interest in interorganelle membrane contact sites, the field will benefit from clear rules to define and study them. In this Perspective, a panel of experts aims to provide this growing field with guidelines for experimental definition and analysis.
Biological circadian rhythms maintain a period close to 24 h in coordination with the Earth’s fixed rotational period. Here Webb et al. discuss how external cues continuously adjust phase and period, viewing the oscillator as a dynamically-adjusted plastic system rather than tightly-coupled cogs in a mechanical clock.
