Up and away: ontogenic transference as a pathway for aerial dispersal of microplastics [PDF]
, 2018 Microplastics (MPs) are ubiquitous pollutants found in marine, freshwater and terrestrial ecosystems. With so many MPs in aquatic systems it is inevitable that they will be ingested by aquatic organisms, and be transferred up through the food chain ...

Coronaviruses in Aquatic Organisms
, 2016 Members of the family Coronaviridae are evolutionarily related and play an important role in human and veterinary medicine. Taxonomic classification is based on the ultrastructure and morphogenesis of viral particles and on biochemical and molecular features. The family Coronaviridae belongs to the order Nidovirales, and is divided into two subfamilies:

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion
Advanced Robotics Research, EarlyView.This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Molecular biomarkers and toxic consequences of impact by organic pollution in aquatic organisms [PDF]
, 1994 Organic contaminants are readily bioaccumulated by aquatic organisms. Exposure to and toxic effects of contaminants can be measured in terms of the biochemical responses of the organisms (i.e. molecular biomarkers).
