Archives of impact: The politics of craters on Earth
Geographical 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.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Understanding the interplay between micrometeoroid impacts and solar wind irradiation is crucial for interpreting lunar surface evolution. Using reactive molecular dynamics simulations and surface binding energy (SBE) analyses, this study investigates the coupled effects of these two dominant space weathering processes on lunar regolith ...

Rapid Communications in Mass Spectrometry, Volume 40, Issue 7, 15 April 2026.ABSTRACT Rationale Distribution patterns of foraminifera are controlled by environmental parameters such as temperature, salinity, and nutrient concentrations in each water mass. Since trace elements to Ca ratios of marine microfossil calcite test of foraminifera record environmental and ecological habitat information, we used femtosecond (fs) LA‐ICP ...

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.Catch and environmental performance of modified scallop dredge designs were assessed. Skid belly bags increased scallop catch by 14%–19% and reduced gear wear. N‐Virodredge reduced catch of scallop juveniles and sorting time. Gear footprint on the seabed was reduced by 50% for skid belly bags. N‐Virodredge cut fuel use by 30%, reducing carbon emissions

Prebiotic Organic Chemistry of Diketopiperazines
Asian Journal of Organic Chemistry, Volume 15, Issue 4, April 2026.Diketopiperazines (DKPs) are considered essential in many life forms, but their prebiotic importance has not been fully understood. This review aims to discuss prebiotic organic chemistry for experimentally and computationally simulated reactions involving DKPs. ABSTRACT Even though the significance of amino acids and polypeptides is well recognized in
