Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

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.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Expanding the members of ultra-high temperature ceramics and their maximum service temperature exceeding 3000 °C

Journal of Advanced Ceramics
Aerodynamic heating, oxidation, ablation, and high dynamic pressure represent the extreme environments that aerospace vehicles must withstand during high-Mach atmospheric or trans-atmospheric flight. The temperature of critical components on the vehicles

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Nature-inspired (Ti,Zr,Hf)C/SiC micro-nano composites with enhanced ablation resistance through a Gobi Desert-like protective oxide layer

Journal of Advanced Ceramics
(Ti,Zr,Hf)C/SiC composites with micro-nano structure were designed inspired by the gravel–sand structure of the wind-resistant Gobi Desert to prevent air-plasma flame scouring and obtain excellent ablation resistance.

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 ...

A novel lightweight near-non-ablation HfO2–SiBOC ceramic: From SiHfBOC precursor synthesis to oxyacetylene flame testing at 2000 °C

Journal of Advanced Ceramics
Carbide- and boride-based ultrahigh temperature ceramics (UHTCs) are the materials of choice for hypersonic vehicles and scramjet engines. Nevertheless, these UHTCs are prone to oxidation in an oxygen-containing atmosphere.
