Terra Nova, Volume 38, Issue 1, Page 1-8, February 2026.ABSTRACT The early Miocene unconformity (EMU) formed during a transition in the tectonic regime of western North America that coincided with faunal diversification. The Railroad Canyon section in the northern Rocky Mountains provides a complete geologic record around this event. Our new magnetostratigraphic study in combination with published U‐Pb ages

A Seismically Active Shear Zone in the Uppermost Mantle Beneath the Canadian Rockies
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Continental mantle earthquakes are uncommon but hold important clues for understanding lithospheric rheology. Few of these earthquakes (<10) have been documented in western North America, though it is likely more exist owing to difficulties in resolving focal depth for small earthquakes.

Geological Journal, Volume 61, Issue 1, Page 127-145, January 2026.Using DZmix and DZstats models, we quantified the contributions of potential sources of the Lanzhou basin. Our findings indicate that the Cenozoic cooling and denudation signals primarily originated from Qilian and West Qinling, which were the main sediment sources.

Non‐enzymatic glycolysis and pentose phosphate pathway‐like reactions in a plausible Archean ocean
Molecular Systems Biology, 2014 The reaction sequences of central metabolism, glycolysis and the pentose phosphate pathway provide essential precursors for nucleic acids, amino acids and lipids. However, their evolutionary origins are not yet understood.

HemaSphere, Volume 10, Issue 1, January 2026.Abstract Diamond–Blackfan anemia (DBA) is a rare bone marrow failure syndrome accompanied by cardiovascular, skeletal, and urogenital abnormalities. Most of the affected individuals carry mutations in ribosomal proteins, including RPS19, a component of the 40S ribosomal subunit.

Redox BiologyRecent research has hypothesized that hydrogen peroxide (H2O2) may have emerged from abiotic geochemical processes during the Archean eon (4.0–2.5 Ga), stimulating the evolution of an enzymatic antioxidant system in early life. This eventually led to the

Heat Transfer, Volume 55, Issue 1, Page 764-774, January 2026.ABSTRACT This review explores the impact of gravitational instability on convective heat transfer, integrating existing research results and theoretical models. Gravitational instability is vital in promoting or hindering convective actions in different systems, such as atmospheric events, ocean currents, and industrial processes.

Geophysical Research Letters, 1984 Nd isotopic data require that most Archean igneous rocks are derived from depleted or undepleted mantle sources while geochemical model stuides necessitate enriched sources for most Archean tonalites. This apparent contradiction can be reconciled if the enriched sources are produced by short‐lived (≤150 m.y.) enrichment of depleted sources.

Journal of Quaternary Science, Volume 41, Issue 1, Page 4-24, January 2026.ABSTRACT The sediment signature of glacial erosion products exported from Hudson Strait to the Labrador Sea during Hudson Strait Heinrich (HS‐H) events is evaluated using four distinct proxies: paired δ18Ο and δ13C data on the carbonate fraction, εNd and U–Pb isotopes in the silicate fraction, the mineral composition of the <2 mm bulk sediment fraction,
