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 ...

Hydrothermal Vesuvianite: A U-Pb Dating Mineral
LithosphereAbstract Since mineral deposits are the products of multiple hydrothermal pulses, in many circumstances, selecting a robust mineral to date the different mineralization events precisely is important. Vesuvianite, usually known as a rock-forming or accessory silicate mineral typically found in metasomatic and regional metamorphic ...

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.

A relational database of global U–Pb ages
Geoscience Frontiers, 2018 Abstract Enhanced understanding of how sampling techniques affect estimates of the global U–Pb age-distribution have, in turn, constrained U–Pb database design. Recent studies indicate that each continent has a unique age-distribution, as determined by zircon ages dated by the U–Pb isotope method.

Modelling stem cell differentiation related processes—A practical overview for biologists
FEBS Letters, EarlyView.Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

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
