Fraternal cooperation of hierarchical cancer parallels metazoan multicellularity and eusociality
ABSTRACT Metazoan multicellularity and eusociality — both outcomes of the fraternal major transitions — have numerous features in common such as uneven distribution of group‐establishing potential. In addition to this framework, I argue herein that the group‐forming principles of metazoan multicellularity and eusociality are analogous to hierarchical ...

Model systems for regeneration: Hydra
The freshwater polyp Hydra provides a potent model system for investigating the conditions that promote wound healing, reactivation of a developmental process and, ultimately, regeneration of an amputated body part.

Background The planarian Schmidtea mediterranea and the cnidarian Hydra vulgaris have emerged as valuable model organisms in regeneration and stem cell research because of their prominent ability to regenerate a complete organism from any small body ...

Sheets of epithelial cells allow animal tissues to define inside and outside, and as such are arguably the fundamental building block of metazoan life. Because of this topological role, the folding, stretching, and on occasion disruption of epithelial sheets is a central feature of both embryonic development and tissue regeneration.

Co‐applying half‐rate BMC layer: (i) Reduced nutrient inputs and (ii) produced similar yield. ABSTRACT Developing high‐efficiency fertilizers with less environmental footprint is essential for sustainable cropping systems. This study evaluated a biochar mineral complex (BMC) to reduce nutrient leaching and increase nutrient use efficiency (NUE), yield,

ABSTRACT Digital image correlation (DIC) is a widely used experimental technique for measuring full‐field deformation, but its application to complex scenarios involving large deformations, discontinuities, or intricate geometries is often hampered by the need for manual region of interest (ROI) definition.

Effects of predation by Hydra (Cnidaria) on cladocerans (Crustacea: Cladocera)
Planktonic cladocerans have evolved different strategies to avoid predation from vertebrates; these include changes in morphology, behavior, physiology, and/or life-history traits.

Towards the standardization of Hydra vulgaris bioassay for toxicity assessments of liquid samples
The Hydra vulgaris bioassay is recognized as sensitive invertebrate test species for toxicity assessment of real-life environmental mixtures for enforcement and monitoring investigations. The purpose of this study was to characterize the intra-laboratory

Linalool acts as a fast and reversible anesthetic in Hydra.
The ability to make transgenic Hydra lines has allowed for quantitative in vivo studies of Hydra regeneration and physiology. These studies commonly include excision, grafting and transplantation experiments along with high-resolution imaging of live ...
