Redox reactions in subducted CaCO3–Fe–SiO2 as a potential source of superdeep diamond inclusions

Scientific Reports
CaCO3 is one of the most abundant carbonates at the Earth’s surface. It is transported into the mantle in substantial quantities via subducted slabs and participates in the deep mantle carbon cycle along with other mantle materials.

Relationship between earth pressure and wall displacement based on Coulomb earth pressure model

Yantu gongcheng xuebao, 2018
The magnitude of earth pressure is greatly influenced by wall displacement. Based on the viewpoint that the relationship between wall displacement and lateral earth pressure is the macroscopic embodiment of soil stress-strain behavior, the relationship ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

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 ...

Conductivity-elevated by brucite amorphization and implication for electrical anomalies in shallow subduction zones

Communications Earth & Environment
Pervasive high-conductivity anomalies in shallow cold subduction zones (40–70 km depths, corresponding to 1–2 GPa) remain unexplained by conventional mechanisms (e.g., dehydration fluids).

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

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
