Pilliga Ghosts: The Novel Fungi of the Rivers, Creeks, Lakes, and Dams of the Narrabri Region, Australia

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Freshwater systems of the semi‐arid Narrabri region, Australia, are hotspots of novel fungal and eukaryote diversity, dominated by zoosporic fungi and unclassified lineages. ITS‑based DNA and water chemistry analyses across various water bodies revealed strong seasonal patterns, a scarcity of aquatic hyphomycetes that may reflect environmental ...

Mini-Workshop: Einstein Metrics, Ricci Solitons and Ricci Flow under Symmetry Assumptions

, 2014
Symmetry reduction methods play an important role in the study of Einstein metrics, Ricci solitons and Ricci flow. The general aim of this mini workshop was to gather researchers who have expertise in the construction of geometric examples and to survey ...

The Aging Microenvironment Shapes Angiogenic Remodeling in IBD‐Associated Colorectal Carcinogenesis

Aging Cell, Volume 25, Issue 6, June 2026.
In IBD, chronic inflammation promotes cellular senescence across epithelial, stromal, endothelial, and immune compartments. The resulting SASP drives pathological angiogenesis, vascular dysfunction, hypoxia, and immune suppression, thereby facilitating progression from inflammation to dysplasia and colitis‐associated colorectal cancer.

Modulation of KATP channels by diazoxide preserves mitochondrial function and barrier integrity under staurosporine‐induced epithelial stress

British Journal of Pharmacology, Volume 183, Issue 12, Page 3213-3233, June 2026.
Background and Purpose Intestinal barrier dysfunction caused by mitochondrial stress, oxidative damage and apoptosis, are hallmarks of dysbiosis‐associated gastrointestinal (GI) disorders. Staurosporine causes downstream features of dysbiosis‐induced epithelial damage.

Ricci flows with unbounded curvature

, 2013
We show that any noncompact Riemann surface admits a complete Ricci flow g(t), t is an element of [0, infinity), which has unbounded curvature for all t is an element of [0, infinity)

ESG Thematic Bonds in Emerging Markets: Risk, Uncertainty, and Ambiguity

European Financial Management, Volume 32, Issue 3, Page 1005-1040, June 2026.
ABSTRACT We examine the impact of risk aversion, ambiguity, and uncertainty (geopolitical and economic) on the ESG thematic bond markets in emerging countries. We analyze ESG sovereign (both USD and local currency denominated) and corporate bond markets on the aggregate and regional levels.

Splitting maps in Type I Ricci flows

We study the existence and small scale behaviour of almost splitting maps along a Ricci flow satisfying Type I curvature bounds. These are special solutions of the heat equation that serve as parabolic analogues of harmonic almost splitting maps, which ...

Cohomogeneity‐one solitons in Laplacian flow: Local, smoothly‐closing and steady solitons

Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.
Abstract We initiate a systematic study of cohomogeneity‐one solitons in Bryant's Laplacian flow of closed G2$\text{G}_2$‐structures on a 7‐manifold, motivated by the problem of understanding finite‐time singularities of that flow. Here, we focus on solitons with symmetry groups Sp(2)${\rm Sp}(2)$ and SU(3)${\rm SU}(3)$; in both cases, we prove the ...

The RhoA guanine exchange factor ABR: a glucose‐sensitive mediator of actin reorganization in feto‐placental arterial endothelial cells altered by gestational diabetes mellitus

The Journal of Physiology, Volume 604, Issue 11, Page 4387-4404, 1 June 2026.
Abstract figure legend Schematic representation of proposed relationship between hyperglycaemia, gestational diabetes mellitus (GDM), active BCR‐related (ABR), RhoA and actin organization of feto‐placental arterial endothelial cells (fpEC). Hyperglycaemia upregulates ABR, which in turn increases RhoA activation.
