At the Edge of Survival: Exploring the Frontiers of Tardigrade Extreme Stress Tolerance

Molecular Ecology, Volume 35, Issue 14, July 2026.
ABSTRACT Tardigrades possess extraordinary resilience to extreme environmental conditions, including near‐complete desiccation, severe levels of radiation, the vacuum of space and extreme sub‐zero temperatures. Despite significant interest in their survival strategies, the molecular mechanisms underlying their survival during extreme stresses have ...

The Polymers of Life: Exploring Cellular Function Through Polymer Concepts

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Biomolecular phase separation reveals that a hidden layer of cellular organization is governed by the principles of polymer science. This review bridges polymer physics and cell biology, offering a primer on fundamental concepts, proposing a framework for interrogating cellular function, and synthesizing biophysical methods for decoding macromolecular ...

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

The tardigrade damage suppressor protein binds to nucleosomes and protects DNA from hydroxyl radicals

eLife, 2019
Tardigrades, also known as water bears, are animals that can survive extreme conditions. The tardigrade Ramazzottius varieornatus contains a unique nuclear protein termed Dsup, for damage suppressor, which can increase the resistance of human cells to ...

An Integrated Assessment of European Soil Health and Restoration Potential

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 2, June 2026.
ABSTRACT Soils host a significant proportion of biodiversity on Earth providing ecosystem functions vital to human well‐being, making it imperative to include them and their ecological features when addressing sustainability goals. We performed a comprehensive assessment of soil health across Europe by explicitly integrating biotic and abiotic ...

Tardigrades of North America: Additions to Montana’s Biodiversity Including a New Species, Platicrista loloensis nov. sp. (Parachela, Hypsibioidea, Itaquasconinae)

Diversity
A total of 205 tardigrades representing two orders, five families, nine genera and ten species were extracted from a moss sample (104 tardigrades) and a lichen sample (101 tardigrades) collected near Missoula, Montana, in 2016.

From niche theory to demographic realities: the demographic niche concept for understanding range‐wide population dynamics

Ecography, Volume 2026, Issue 5, May 2026.
The ecological niche concept is fundamental to understanding species distributions but often overlooks the demographic processes shaping said distributions. Conversely, demographic theory has traditionally neglected how vital rates vary and covary across environments, limiting our understanding of population dynamics across species' ranges.

Assessment of Preservation and Extraction Methods for Environmental DNA in Sediments

Environmental DNA, Volume 8, Issue 3, May–June 2026.
We assessed how different preservation methods (freezing, room temperature, silica gel, Longmire buffer) affect eDNA metabarcoding results for bacterial, fungal, microeukaryotic, and metazoan communities in marine and freshwater sediments. Results demonstrate taxonomic‐ and habitat‐specific responses to preservation methods, providing evidence‐based ...

Comparative transcriptomics reveal a novel tardigrade-specific DNA-binding protein induced in response to ionizing radiation

eLife
Tardigrades are microscopic animals renowned for their ability to withstand extreme conditions, including high doses of ionizing radiation (IR). To better understand their radio-resistance, we first characterized induction and repair of DNA double- and ...

The complete mitochondrial genome of Echiniscus testudo (Heterotardigrada: Echiniscidae)

Mitochondrial DNA. Part B. Resources, 2018
The complete mitchondrial genome of Echiniscus testudo, a cosmopolitan heterotardigrade collected in Japan, has been sequenced using a single molecule real-time (SMRT) sequencing long read after whole genome amplification from a single individual.
