Conserved SERPINE2 function maintains ovarian estrogen production to support fertility in goats and mice

iMetaOmics, EarlyView.
Single‐nucleus RNA sequencing and functional profiling of goat ovaries with divergent litter sizes revealed prolificacy‐associated granulosa cell (GC) states characterized by enhanced proliferation‐ and steroidogenesis‐related features, together with altered predicted cell–cell communication.

Human-wildlife conflicts in Latin America: A systematic review of jaguars (Panthera onca) and Andean bears (Tremarctos ornatus)

Biota Colombiana
Forest cover in Latin America has decreased in recent years due to the expansion of agriculture, forestry, and livestock ranching, exacerbating human-wildlife conflicts (HWC).

HER2‐Targeted AIE Nanotheranostics Overcome SHR‐A1811 Resistance via Immunogenic Pyroptosis and Tumor‐Associated Macrophage Reprogramming in Breast Cancer

Small, EarlyView.
HER2‐targeted AIE780‐A1811 nanoparticles self‐assemble via amide coupling of a mitochondria‐directed photosensitizer with the ADC SHR‐A1811. Upon 660 nm irradiation, they generate ROS, photothermal effects, and controlled drug release, inducing immunogenic pyroptosis and M2‐to‐M1 macrophage reprogramming. This dual action remodels the immunosuppressive

Adjusting Our Thinking About Feeding Animals: Fiber as the Metric for Mimicking Natural Diets

Zoo Biology, EarlyView.
A typical effect of the change of an animal group to a diet higher in fiber: juveniles keep growing, animals of ideal body weight maintain their weight, and obese individuals lose weight. ABSTRACT Free‐ranging animals often ingest markedly different diets than their counterparts under human care, whether companion animals, production animals, or zoo ...

Opportunities and Alliances: The Relational Dynamics of Criminal Collusion in Latin America

The British Journal of Sociology, EarlyView.
ABSTRACT Based on ethnographic fieldwork in Mexico and judicial wiretap analysis in Argentina, this paper shows that collusion between state actors and violent non‐state actors operates through fluid and competitive relational networks rather than stable hierarchies or fixed institutional arrangements.

Captive Breeding of the Chinese Alligator Reduces Inbreeding but Increases Genetic Load

Integrative Zoology, EarlyView.
Captive breeding of the Chinese alligator successfully reduced genomic inbreeding but increased the burden of deleterious mutations. Genomic analyses indicate that managing both genetic diversity and genetic load is essential for the long‐term conservation of this critically endangered species.

Finding Dr Florence Buchanan: The recovered face and fuller life story of a scientific legend

Experimental Physiology, Volume 111, Issue 10, Page 4360-4367, 1 October 2026.
Abstract Dr Florence Buchanan (1867–1931) was one of physiology's foundational women. Trained as a zoologist at University College London (UCL), she became an exacting physiologist whose studies of muscle bioelectricity, reflexes, cardiac rhythm and exercise helped shape twentieth‐century physiology.

Range fragmentation in the spectacled bear Tremarctos ornatus in the northern Andes [PDF]

Oryx, 2004
This paper addresses the conservation status of the spectacled bear Tremarctos ornatus in the northern Andes (Venezuela, Colombia and Ecuador) by analysing the degree of range fragmentation and estimating habitat availability. From satellite images we constructed maps of remnant habitat blocks, consisting of Andean forest and páramo (high elevation ...

Single‐Cell Reveal GALNT7‐Dependent Ferroptosis Suppression as a Mechanism of Immunotherapy Resistance in Non‐Small Cell Lung Cancer

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Integrated clinical and mechanistic analyses identify GALNT7 as a ferroptosis‐suppressive regulator associated with immunotherapy resistance in non‐small cell lung cancer. GALNT7 depletion promotes lipid peroxidation, mitochondrial dysfunction, and ferroptosis, enhances CD8+ T‐cell activation and IFN‐γ production, and sensitizes tumors to PD‐1 blockade,
