Impact of light pollution on fishes: Mechanisms and ecological consequences

Journal of Fish Biology, EarlyView.
Abstract The increasing prevalence of artificial light at night (ALAN) is of growing ecological concern. By altering natural light regimes, ALAN affects the behaviour, physiology and life‐history of organisms. While research has largely focused on terrestrial ecosystems, aquatic ecosystems are increasingly exposed.

First cytogenetic characterization of the southern pygmy perch Nannoperca australis (Teleostei: Percichthyidae): Karyotype, heterochromatin and repetitive DNA organization

Journal of Fish Biology, EarlyView.
Abstract Chromosome organization and repetitive DNA distribution are important components of genome evolution in teleost fishes but remain poorly characterized in many species of ecological and conservation relevance. We performed a detailed cytogenetic analysis of the southern pygmy perch, Nannoperca australis, a small freshwater species widely used ...

microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

New Phytologist, EarlyView.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Toward “Obesityomics”: Domain‐Specific Omics in Precision Obesity Medicine with a Brief AI Perspective

Obesity Reviews, EarlyView.
ABSTRACT Background Obesity's global rise has outpaced the effectiveness of “one‐size‐fits‐all” prevention and treatment strategies. The promise of precision medicine lies in addressing the etiological and biological diversity of obesity and transforming it into actionable endotypes.
