Stem cell differentiation trajectories in Hydra resolved at single-cell resolution
Science, 2018 Mapping Hydra development cell by cell Hydra continually renews all cells in its body using three stem cell populations. This feature of Hydra allowed Siebert et al.

Biological Reviews, EarlyView.ABSTRACT Three categories of explanations exist for why we age: mechanistic theories, which omit reference to evolutionary forces; weakening force of selection theories, which posit that barriers exist that prevent evolutionary forces from optimising fitness in ageing; and optimisation theories, which posit that evolutionary forces actually select for ...

A new look at the architecture and dynamics of the Hydra nerve net
bioRxivThe Hydra nervous system is the paradigm of a “simple nerve net”. Nerve cells in Hydra, as in many cnidarian polyps, are organized in a nerve net extending throughout the body column.

Comparative Aspects of Structure and Function of Cnidarian Neuropeptides
Frontiers in Endocrinology, 2020 Cnidarians are early-branching animals in the eukaryotic tree of life. The phylum Cnidaria are divided into five classes: Scyphozoa (true jellyfish), Cubozoa (box jellyfish), Hydrozoa (species, Hydra and Hydractinia), Anthozoa (sea anemone, corals, and ...

Biological Reviews, EarlyView.ABSTRACT Basal and standard metabolic rate (BMR and SMR) are cornerstones of physiological ecology and are assumed to be relatively fixed intrinsic properties of organisms that represent the minimum energy required to sustain life. However, this assumption is conceptually flawed. Many core maintenance processes underlying SMR are temporally partitioned

Diurnal and circadian regulation of opsin-like transcripts in the eyeless cnidarian Hydra
Biomolecular ConceptsOpsins play a key role in the ability to sense light both in image-forming vision and in non-visual photoreception (NVP). These modalities, in most animal phyla, share the photoreceptor protein: an opsin-based protein binding a light-sensitive ...

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution
ChemSusChem, Volume 18, Issue 6, March 15, 2025.This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.

Microscopy Research and Technique, EarlyView.Atomic force microscopy enables precise evaluation of the magnitude and range of hydrophobic and van der Waals interactions. This primer presents a protocol for fluorocarbon functionalization of gold surfaces and examines how water: DMSO mixtures affect hydrophobic forces, with data interpreted through an extended van der Waals model.

BMC Cell Biology, 2011 Background The Notch signalling pathway is conserved in pre-bilaterian animals. In the Cnidarian Hydra it is involved in interstitial stem cell differentiation and in boundary formation during budding.
