The Influence of Elevated Temperature on Time‐Dependent Compaction Creep in Bleursville Sandstone

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The inelastic compaction of sandstone in the upper crust typically occurs at depths where temperatures range from approximately 50°C $50{}^{\circ}\mathrm{C}$ to 150°C $150{}^{\circ}\mathrm{C}$. Previous experimental studies have shown that even this modest temperature increase can reduce the yield stress required to initiate inelastic ...

Reviewing seas of data: Integrating image‐based bio‐logging and artificial intelligence to enhance marine conservation

Methods in Ecology and Evolution, Volume 17, Issue 2, Page 272-290, February 2026.
Abstract Conservation of marine ecosystems can be improved through a better understanding of ecosystem functioning, particularly the cryptic underwater behaviours and interactions of marine predators. Image‐based bio‐logging devices (including images, videos and active acoustic) are increasingly used to monitor wildlife movements, foraging behaviours ...

The Influence of 25‐ and 90‐Min Afternoon Nap Opportunities on Subsequent Nighttime Sleep in Student Athletes

Journal of Sleep Research, Volume 35, Issue 1, February 2026.
ABSTRACT While daytime napping could support recovery in athletes, poorly timed or prolonged naps may interfere with nighttime sleep. Therefore, this study aimed to explore the effect of two different, well‐timed nap opportunity durations, 25 and 90 min, on subsequent objectively measured nighttime sleep in student athletes.

Substitutions of Sleep, Physical Activity, and Sedentary Behaviour and the Risk of Dementia and Stroke

Journal of Sleep Research, Volume 35, Issue 1, February 2026.
ABSTRACT Sleep, sedentary behaviour, and physical activity (PA) are important for brain health. Spending more time in one behaviour always substitutes time in another, which may affect associations and should be considered in prevention strategies. We assessed how substitutions of sleep, sedentary behaviour, and PA are associated with incident dementia
