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

Terra 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‐

Unraveling genetic diversity and loci conferring leaf blast resistance in East and Southern African rice germplasm

Crop Science, Volume 66, Issue 2, March/April 2026.
Abstract Rice blast remains a major disease, causing severe yield losses in rice‐producing regions and posing a threat to global food security. Understanding genetic variation within germplasms is crucial for identifying locally adapted genotypes with beneficial alleles for improving resistance to this disease.

Quantifying Historical and Future Surface Soil Moisture Drying Using Deep Learning and Remote Sensing

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Understanding historical and future surface soil moisture (SSM) drying is pivotal due to its close links with droughts, heatwaves, and wildfires, yet debates regarding its evolution persist. In this study, we leverage advanced deep learning techniques to fill gaps of remote sensing‐based SSM data during 1983–2020 and therefore use these gap ...

Ribcage Morphology in Native South American Populations From Different Altitudes: Insights From a Global Comparative Framework

American Journal of Human Biology, Volume 38, Issue 2, February 2026.
ABSTRACT Objectives Altitude shapes human morphology as highland populations must cope with cold and hypoxic environments. Although Andean highlanders have been proposed to exhibit larger and deeper ribcages, this idea is mainly based on research using disarticulated skeletal elements or non‐South American controls. The objective of this research is to
