C. elegans in Complex Media [PDF]
arXiv, 2011 We experimentally studied the locomotion of the nematode C. elegans in both fluidic and granular media. In this fluid dynamics video, we show the motility gaits of the nematode in these two environments. The motility of the nematode C. elegans is investigated using particle tracking methods.

Undulatory swimming in shear-thinning fluids: Experiments with C. elegans [PDF]
, 2014 The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of shear-thinning viscosity on the swimming behaviour of an undulatory swimmer, the nematode Caenorhabditis elegans.

RNA‐Based Biopesticides: Pioneering Precision Solutions for Sustainable Aquaculture in China
Animal Research and One Health, EarlyView.The Chinese dragon represents RNA biopesticides, which effectively counteract bacterial, viral, and parasitic threats, safeguarding aquatic life. This method is precise, focusing solely on harmful agents and sparing beneficial aquaculture species. Its innovative nature protects aquatic environments while reducing ecological footprint.

The collective motion of nematodes in a thin liquid layer [PDF]
arXiv, 2010 Many organisms live in confined fluidic environments such as the thin liquid layers on the skin of host organisms or in partially- saturated soil. We investigate the collective behaviour of nematodes in a thin liquid layer, which was first observed by Gray and Lissmann, [J. Exp. Biol. 41, 135 (1964)]. We show experimentally that nematodes confined by a

A Device to Measure the Propulsive Power of Nematodes [PDF]
arXiv, 2011 In the fluid dynamics video, we present a microfluidic device to measure the propulsive power of nematodes. The device consists of a tapered conduit filled with aqueous solution. The conduit is subjected to a DC electric field with the negative pole at the narrow end and to pressure-driven flow directed from the narrow end.

Undulatory locomotion of {\it C. elegans} on wet surfaces [PDF]
, 2011 The physical and bio-mechanical principles that govern undulatory movement on wet surfaces have important applications in physiology, physics, and engineering. The nematode {\it C. elegans}, with its highly stereotypical and functionally distinct sinusoidal locomotory gaits, is an excellent system in which to dissect these properties.

Cytoskeleton, EarlyView.ABSTRACT Cells have an intrinsic ability to rapidly respond to environmental change to regulate cell cycle progression and membrane organisation, thereby affecting cell growth and division. The actin cytoskeleton is a highly dynamic complex of proteins that can rapidly reorganise to change the growth pattern of a cell.

Ecotoxicity and Sustainability of Emerging Pb‐Based Photovoltaics
Solar RRL, Volume 6, Issue 12, December 2022., 2022 This review provides a unique vision of the ecotoxicity and sustainability of emerging Pb halide perovskite solar cells and Pb chalcogenide quantum dot solar cells. The critical role of Pb, the causes of Pb leakage, the hazardous impact, Pb leakage reduction strategies, and Pb recycling strategies of end‐of‐life solar cells are systematically analyzed.

The effects of fluid viscosity on the kinematics and material properties of C. elegans swimming at low Reynolds number [PDF]
arXiv, 2009 The effects of fluid viscosity on the kinematics of a small swimmer at low Reynolds number are investigated in both experiments and in a simple model. The swimmer is the nematode Caenorhabditis elegans, which is an undulating roundworm approximately 1 mm long. Experiments show that the nematode maintains a highly periodic swimming behavior as the fluid
