Journal of Applied Polymer Science, Volume 143, Issue 15, April 15, 2026.DIW 3D printing of silicone materials can be optimized by controlling their gelling behavior or curing mechanism with carbon nanotubes. This precision control results in high‐performance elastomer materials and is a model study for characterization methods.

Male and female stem cells and sex reversal in Hydra polyps [PDF]
, 1986 Single interstitial stem cells of male polyps of Hydra magnipapillata give rise to clones that differentiate either male or female gametes. To test the sexual stability of these clones, stem cells were recloned.

Circumbinary Chaos: Using Pluto's Newest Moon to Constrain the Masses of Nix & Hydra
, 2012 The Pluto system provides a unique local laboratory for the study of binaries with multiple low mass companions. In this paper, we study the orbital stability of P4, the most recently discovered moon in the Pluto system.

Biological Reviews, Volume 101, Issue 2, Page 911-925, April 2026.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 ...

Integration of epigenetics into ecotoxicology: insights and fundamental research needs
Biological Reviews, Volume 101, Issue 2, Page 826-847, April 2026.ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

The Biological Bulletin, 1997 Embryogenesis in hydra includes a variable period of dormancy; and this period, as well as subsequent stages through hatching, takes place within a thick cuticle that hinders observation. Thus, although the early stages of development have been well-characterized qualitatively, the middle and later stages are only poorly understood.

American Journal of Human Biology, Volume 38, Issue 3, March 2026.ABSTRACT Background and Aims Accurate measurement of total energy expenditure (TEE) is critical for maintaining energy balance and body weight. This study aimed to analyze differences in TEE assessed by the doubly labeled water method (DLW‐TEE), using food quotient (FQ) derived from self‐reported 24‐h dietary recalls, respiratory quotient measured by ...

The Origin of Mucosal Immunity: Lessons from the Holobiont
mBio, 2016 Historically, mucosal immunity—i.e., the portion of the immune system that protects an organism’s various mucous membranes from invasion by potentially pathogenic microbes—has been studied in single-cell epithelia in the gastrointestinal and upper ...

Biophysical Journal, 2016 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.
