Potential health benefits of cold‐water immersion: the central role of PGC‐1α

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Hibernation: the immune system at rest?

open access: yes, 2010
Mammalian hibernation consists of torpor phases when metabolism is severely depressed, and T can reach as low as approximately -2 degrees C, interrupted by euthermic arousal phases.

Where the wild rose blooms: A phenology of grounded writing

open access: yesAnthropology and Humanism, Volume 51, Issue 2, December 2026.
Abstract This flash tip reflects on a phenology of grounded writing, emerging through reciprocal attention and embodied observation across four seasons. Drawing on land‐based methodologies and creative ethnography, I offer reflections for scholars seeking to write otherwise through the practice of standing in solidarity with two feet in one place.

The mechanism of hibernation.

open access: yes, 1928
The hibernating mammal presents several unique features as regards metabolism. The change from the homoiothermic to the poikilothermic condition, and vice versa, is of considerable interest.

Anatolian ground squirrel (Spermophilus xanthoprymnus) retina: Comparative expression of synaptophysin, NeuN, calbindin-D28k, parvalbumin, glial fibrillary acidic protein, and Iba-1 during pre-hibernation and hibernation

open access: yes
Hibernation induces significant molecular and cellular adaptations in the retina to maintain function under reduced metabolic conditions. This study aimed to investigate the expression of neuronal, synaptic, and glial markers in the retina of ...

Flight of the dragons: a global review of migration in Odonata

open access: yesBiological Reviews, Volume 101, Issue 5, Page 2134-2157, October 2026.
ABSTRACT Insects are the most abundant and ecologically important animal migrants. Yet, we know relatively little about the patterns and processes underlying insect migration. Dragonflies (Anisoptera) and damselflies (Zygoptera) comprise the ancient insect order Odonata, whose ancestors were the first organisms to fly on Earth.

The photoperiodism and hibernation

open access: yes, 2016
Many organisms living in seasonal environments use annual changes in the length of the day for timing of their responses, such as reproduction, migration or hibernation. Hibernation allows animals to survive difficult periods associated particularly with

Cell Type‐Specific Extracellular Vesicles in Mouse Brain: Proteomic Signatures Highlight Astrocytic GlialCAM Network and GPCR Enrichment

open access: yesGlia, Volume 74, Issue 10, October 2026.
Cell type–specific EVs were isolated from mouse brain and profiled by proteomics. Each EV subtype exhibited proteomic signatures consistent with the specialized functions of its cell of origin. Astrocyte‐derived EVs (ADEVs) were enriched for the GlialCAM/MLC1 network and GPCRs.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full
