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.

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).

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

Experimental Physiology, EarlyView.
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.

Quantitative assessment of masticatory muscles based on skull muscle attachment areas in Carnivora

The Anatomical Record, Volume 309, Issue 9, Page 2368-2394, September 2026.
Abstract Masticatory muscles are composed of the temporalis, masseter, and pterygoid muscles in mammals. Each muscle has a different origin on the skull and insertion on the mandible; thus, all masticatory muscles contract in different directions. Collecting in vivo data and directly measuring the masticatory muscles anatomically in various Carnivora ...

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 ...

Integrated Single‐Cell RNA Sequencing and Untargeted Metabolomics Reveals β‐Elemene's Immune and Metabolic Modulation in Triple‐Negative Breast Cancer

MedComm – Oncology, Volume 5, Issue 3, September 2026.
In a 4T1 TNBC model, β‐elemene suppressed tumor growth and pulmonary metastasis. scRNA‐seq showed it remodeled the tumor microenvironment by reducing cancer‐associated fibroblasts, enhancing antigen presentation, and inhibiting pro‐tumorigenic ECM remodeling. Metabolomics revealed prostaglandin downregulation.

Tumor‐Derived LAMB3 Drives Immunosuppressive LRRC15+ Fibroblast Formation During Pancreatic Ductal Adenocarcinoma Development

Advanced Science, Volume 13, Issue 45, 13 August 2026.
A single‐cell atlas of pancreatic ductal adenocarcinoma development reveals progressive ductal‐fibroblast‐immune crosstalk. Tumor‐derived LAMB3 drives the formation of immunosuppressive LRRC15+ fibroblasts through the ITGB1/FAK/MAPK/FOSL2 signaling. Glycolytic reprogramming upregulates LAMB3 and correlates with LRRC15+ fibroblast enrichment.

Mastication‐Induced Electrical Stimulation Activates Prg4+ Chondroprogenitors for Osteoarthritis Therapy

Advanced Science, Volume 13, Issue 45, 13 August 2026.
This study presents a ″trash‐to‐treasure″ strategy that converts harmful joint overloads into beneficial electrical cues. The biodegradable MagPie, by providing piezoelectrical stimulation and releasing Mg2+ during mastication, exerts synergistic pro‐regenerative and anti‐inflammatory effects on Prg4+ cells via the ECM‐mediated FAK‐PI3K‐Akt axis ...

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, Volume 20, Issue 7, Page 1726-1741, July 2026.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.
