Terra Nova, EarlyView.ABSTRACT Thin, discontinuous, organic‐rich oil shale beds in the siliciclastic‐evaporitic Salt Range Formation (SRF) of Pakistan are of approximate Neoproterozoic to Cambrian age based on stratigraphic constraints. The beds are enriched (26–43 wt.% total organic carbon, TOC) in aliphatic organic matter (OM) of low thermal maturity despite their ...

Terra Nova, EarlyView.ABSTRACT Although central Brazil hosts significant ion‐adsorption rare earth element (REE) deposits associated with A‐type granites, their coeval volcanic counterparts have been largely overlooked as exploration targets. This study demonstrates that acidic metavolcanic rocks of the Araí Group share strong radiometric, geochemical and mineralogical ...

Terra Nova, EarlyView.ABSTRACT The Southern Brasília Orogen formed during Western Gondwana's final assembly and comprises nappe systems piled against the São Francisco Craton. We present new rutile U–Pb ages from the lowermost Canastra Group (> 2.2 Ga) and the uppermost Carrancas Group (~560 Ma), integrated with published zircon, monazite, garnet, and mica ages from the ...

The African Mole‐Rat Genus Cryptomys and Its Species: Distinct in Their Genes and Habitats
Zoologica Scripta, EarlyView.ABSTRACTThe African mole‐rat genus Cryptomys comprises five morphologically cryptic lineages distributed across South Africa and in Zimbabwe, historically treated as subspecies of C. hottentotus (C. h. hottentotus, C. h. mahali, C. h. natalensis, C. h. pretoriae and C. h. nimrodi).

A spatial and temporal analysis of seat-belt usage and seat-belt laws [PDF]
Seat-belt usage has increased significantly in the US since the introduction of mandatory seat-belt usage laws in the 1980`s. This paper analyzes the impact of these laws on increasing seat-belt usage while controlling for other state-specific variables.

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.Abstract High temperatures increasingly threaten US soybean [Glycine max (L.) Merr.] seed yields, yet actionable solutions remain limited. The APSIM (Agricultural Production Systems Simulator) model was evaluated against observed regional data from the US Mid‐South, and gridded simulations were conducted across 4651 fields to identify how concurrent ...

Agrosystems, Geosciences &Environment, Volume 9, Issue 4, December 2026.Abstract Agricultural drought significantly threatens food security, livelihoods, and ecosystem stability, especially in regions prone to drought, such as the East Bale zone. This study investigates the spatial and temporal patterns of agricultural drought over 30 years (1993–2024) by combining meteorological station data with satellite‐derived ...

The Earth's Greatest Porous Media
Perspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.Abstract How deeply does modern meteoric water circulate into the continental crust? How deep is the Earth's Critical Zone (CZ), the top layer of the continental lithosphere that co‐evolves with the atmosphere, hydrosphere, and biosphere, extending from vegetation canopy down to fresh bedrock and the base of active groundwater circulation?
