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.

Biodiversity on island chains: neutral model simulations

, 2010
A neutral ecology model is simulated on an island chain, in which neighbouring islands can exchange individuals but only the first island is able to receive immigrants from a metacommunity.

Micro and Nanostructural Diversity of Lizard Osteoderm Capping Tissue in Relation to Mechanical Performance

Advanced Functional Materials, EarlyView.
This study shows that lizard osteoderm capping tissue is a hyper‐mineralized hydroxyapatite layer consistently covering the superficial osteoderm surface in those species studied here, yet it varies greatly in morphology, nanostructure, and mechanical performance across species.

Evaluating Multiple Arthropod Taxa as Indicators of Invertebrate Diversity in Old Fields [PDF]

, 2018
Biodiversity, often quantified by species richness, is commonly used to evaluate and monitor the health of ecosystems and as a tool for conservation planning. The use of one or more focal taxa as surrogates or indicators of larger taxonomic diversity can

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

Advanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Building like a Coral—Parallelized, Multiscale Biofabrication

Advanced Materials, EarlyView.
Corals build stiff, strong, and inherently circular skeletal materials under resource‐ and energy‐limited conditions—offering blueprints for transformative materials. We synthesize the current understanding of coral biomineralization and reframe coral growth as a multiscale, parallelized biofabrication process.

КОНЦЕПЦИЯ ЭВОЛЮЦИИ ЖИЗНИ В СИСТЕМЕ ЗЕМЛЯ-ЛУНА

Journal of Bioinformatics and Genomics
Приливные взаимодействия между Луной и Землей приводят к заметному торможению вращения Земли и к ускорению орбитального движения Луны и к ее удалению от Земли.
