TTG petrogenesis and early plate tectonics

Dizhi lixue xuebao
Objective  TTG (tonalite-trondhjemite-granodiorite) suites, major constituents of Archean continental crust, serve as key archives for understanding the formation and evolution of the early continental crust and related plate tectonic regimes and ...

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

FEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Geodynamics of early Earth tectonic regimes

地球与行星物理论评
Earth is unique in our solar system for having active plate tectonics, and understanding its tectonic regimes and the early evolutionary processes are pivotal to geodynamic research.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Fifteenth century earth science [PDF]

, 1967
The earth science content of two late medieval encyclopedias, the Mirrour of the World and Higden's Polychronicon, both printed by William Caxton in the 1480's, is examined in relation to fifteenth century ideas about the physical nature of the earth and

Nitrogen Oxide Concentrations in Natural Waters on Early Earth [PDF]

, 2019
A key challenge in origins-of-life studies is estimating the abundances of species relevant to the chemical pathways proposed to have contributed to the emergence of life on early Earth.

Design and analysis strategies for robust microbiome ageing research

FEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an
