Pressure‐Controlled Modifications in Electronic Structure, Mechanical, Thermodynamic, and Optoelectronic Attributes of Perovskite NaPaO3 for Energy‐Efficient Applications

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
First principle calculations are carried out first time to study the pressure‐dependent structural, thermodynamic, elastic, electronic, and optical properties of NaPaO3 perovskite oxide. Modified Becke‐Johnson (mBJ) exchange‐correlation potential provides very accurate results.

Wheat breeding approaches for designing wheat to thrive in a warmer world

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 754-763, May 2026.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

Influence of Inherited Rifted Margin Architecture on Continental Collision Dynamics

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Continental collision is a key process in lithospheric evolution, driving mountain building, crustal thickening, and supercontinent assembly. Within the Wilson cycle, collision marks the final stage following rifting, ocean spreading, and subduction.

Changing Regional Land Surface Albedos Alter the Planetary Albedo During the Twenty‐First Century

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract The top‐of‐atmosphere (TOA) albedo controls the amount of solar energy absorbed by Earth and is influenced by the reflectivity of both the atmosphere and surface. With considerable changes in land use over the past few decades it is reasonable to question whether a perturbed surface albedo has influenced TOA albedo over the corresponding ...

Archives of impact: The politics of craters on Earth

open access: yesGeographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.
