Human Research Protections during Emergencies: An Integrative Review

Ethics &Human Research, Volume 48, Issue 3, Page 17-26, May–June 2026.
ABSTRACT The increasing frequency and severity of various types of societal and humanitarian emergencies—e.g., infectious disease outbreaks and natural disasters—creates unique challenges for conducting human subjects research in these settings. These challenges include regulatory review complexities, maintaining research rigor while increasing ...

Drill-string nonlinear dynamics accounting for the drilling fluid

, 2009
The influence of the drilling fluid (or mud) on the drill-string dynamics is analyzed in this paper. Usually the presence of the fluid is not taken into account in the analysis of the nonlinear dynamics of a drill-string. The aim of this paper is to investigate how the fluid affects this dynamics using a simplified fluid-structure interaction model ...

Delousing performance of ballan wrasse (Labrus bergylta) and lumpfish (Cyclopterus lumpus): seasonal consistency and the challenge of cryptic lice for lumpfish

Pest Management Science, Volume 82, Issue 5, Page 4661-4668, May 2026.
Ballan wrasse and lumpfish effectively reduce sea lice on salmon year round, although lumpfish struggle with cryptic lice, highlighting new considerations for lice management. Abstract BACKGROUND Cleaner fish play a crucial role in controlling caligid sea lice in Atlantic salmon aquaculture across the North Atlantic.

Feminist Political Ecology (FPE) Research on Irrigation: A Systematic Literature Review

WIREs Water, Volume 13, Issue 3, May/June 2026.
A review of 12 feminist political ecology (FPE) themes in research on irrigation shows a prominent interest in the effect of power relations at the household and community levels on irrigation access and control in reviewed studies, but other dimensions, such as embodied subjectivities and emotional connections with water, remain relatively overlooked.

Delineating seasonal shifts in reindeer habitat and diet selection by integrating GPS telemetry and stable isotope analysis

Wildlife Biology, Volume 2026, Issue 3, May 2026.
Seasonal changes shape herbivore behaviour by altering forage availability and habitat conditions; however, few studies integrate diet and habitat selection data across temporal scales. This study uses seasonality as a unifying framework to combine fine‐scale GPS‐based habitat selection data with broader‐scale dietary information from stable isotope ...

Ecosystem‐Scale Methane Emissions From Peatlands of the Hudson Bay Lowlands

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Northern peatlands are important sources of methane (CH4) in the atmosphere. However, the magnitude of CH4 emissions and their response to environmental factors are poorly constrained within the Hudson Bay Lowlands (HBL), the largest contiguous peatland complex in North America. This study investigated seasonal (April–November) eddy covariance‐

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

Functional Ecology, Volume 40, Issue 5, Page 1251-1269, May 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Plasma Dilution After Myocardial Ischemia–Reperfusion Injury Promotes Cardiac Repair, Heart Performance, and Recovery of Motor Function and Endurance in Old Mice

Aging Cell, Volume 25, Issue 5, May 2026.
Plasma dilution at 24 h after I/R improved cardiac remodeling, function, and the physical performance of old male and female mice, through lowered markers of inflammation, fibrosis, reduction of cardiomyocytes' apoptosis, increase in their cell‐cycle re‐entry, and healthier profile of newly synthesized proteome, including the determinants of Jak/Stat ...
