Giant Porphyry Copper Deposits Caused by a Slab Jamming in the Mantle Transition Zone

open access: yesTerra Nova, Volume 38, Issue 2, Page 106-115, April 2026.
ABSTRACT Two giant porphyry copper deposits in the Southern Central Andes formed during the Miocene–Pliocene transition when a bend in the subducting Juan de Fernández hotspot chain jammed in the mantle transition zone, causing mega‐scale slab‐kinking. This geometry implies mechanical resistance that caused East–West compression and eventually a thrust‐

ORMDL Proteins Turnover via Proteasome and Autophagy Is Cell‐Type Dependent and Tied to Ceramide Homeostasis

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
ORMDL proteins in the endoplasmic reticulum (ER) negatively regulate serine palmitoyltransferase (SPT) activity in response to the rate of de novo sphingolipid synthesis. Disruption of ceramide homeostasis by myriocin or fumonisin B1 (FB1) appears to destabilize the ORMDL‐SPT complex, leading to ORMDL degradation as a feedback mechanism.

Atmospheric Dynamics of IR‐Active Particles Released From Mars' Surface

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Surface release of radiatively active particles, with high infrared‐ (IR‐)to‐visible extinction ratios, has been proposed as a method of warming Mars. However, to warm Mars using aerosols, particles released locally must disperse globally. Here we provide an initial reference study in a plume tracking, dry Martian atmospheric model to address ...

Modeling the Transport and Dispersion of Volcanic Co‐PDC Ash Clouds Using NAME: An Evaluation of Source Geometry and Mass Eruption Rate

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Pyroclastic density currents (PDCs) are gravity currents that frequently form during explosive volcanic eruptions. These ground‐hugging density currents consist of high‐temperature mixtures of pyroclasts (e.g., ash, pumice), lithics, and gas.

Large Eddy Simulation of Mixed‐Phase Clouds With Aerosol Perturbation: Importance of Effective Radius

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Aerosol‐cloud interactions are a major source of uncertainty in estimating anthropogenic effective radiative forcing. Although warm polluted clouds have been studied to investigate the influence of aerosols on clouds, studies on mixed‐phase polluted clouds are limited. Here we performed Large Eddy Simulations of mixed‐phase clouds with various
