River Sand and Gravel Mining: Global Drivers, Impacts, and Pathways for Sustainable Management

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract River sand and gravel are mined worldwide at volumes that now rival their natural replenishment, yet quantitative knowledge of this mining activity and its consequences lags far behind many other global environmental pressures. We synthesize 411 peer‐reviewed studies published since 1974 within a new Driver‐to‐Management Pathway for ...

Collisionless Shocks: Contemporary State After Three Quarters of a Century of Research

Reviews of Geophysics, Volume 64, Issue 3, September 2026.
Abstract The collisionless shock research started in the late 1950s. Since then, plenty of data have been accumulated due to the large number of missions in the heliosphere, providing in situ measurements of the fields and particles. The quality of these measurements has vastly improved, especially in the last two decades.

Modeling the Histogenetic Switch Between Enameloid and Enamel

Evolution &Development, Volume 28, Issue 3, September 2026.
This evo–devo exploration of ~550,000 histogenetic simulations forming dentine, enameloid, and enamel identifies 38 independent ways to induce the enameloid–enamel transition, with delayed matrix vesicle secretion (SVO‐) emerging as the key modification, providing new insights into the origin of enamel in early osteichthyans.
