Craters and Lunar Lua (Pits/Skylights) in Mare Tranquillitatis and Marius Hills Reveal Variations in Protolith Properties

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

New Insolation Forcing for Paleoclimate Studies

open access: yesPaleoceanography and Paleoclimatology, Volume 41, Issue 1, January 2026.
Abstract Insolation forcing at the top of the atmosphere is widely used in paleoceanographic and paleoclimatological studies. In paleoclimate simulations, it must reflect Earth’s orbital history. General Circulation Models (GCMs) typically use a modern orbital configuration to allow direct comparison to modern and near‐future scenarios, often with time

Non‐Invasive Underwater DNA Sampling Illuminates Red Sea Echinoderm Diversity

open access: yesMolecular Ecology Resources, Volume 26, Issue 1, January 2026.
ABSTRACT Species‐specific non‐invasive underwater DNA sampling remains largely understudied for marine invertebrates despite its potential to revolutionise biodiversity assessment of vulnerable species or fragile ecosystems. Comprehensive species‐specific DNA barcode databases are essential for accurate species identification and taxonomic assignment ...

Origin of asteroid (101955) Bennu and its connection to the New Polana family

open access: yesScientific Reports
The asteroid (142) Polana is classified as a B-type asteroid located in the inner Main Belt. This asteroid is the parent of the New Polana family, which has been proposed to be the likely source of primitive near-Earth asteroids such as the B-type ...
