Beyond the chaos: How architecture structures tumour biology
Tissue architecture shapes tumour initiation and progression through multiple interconnected layers continuously remodelled over time. This review outlines how physical forces, biochemical cues, cellular niches and systemic influences contribute to tumour evolution.

ABSTRACT The degradation of metallic materials due to hydrogen embrittlement (HE) poses critical challenges for structural reliability. Phase‐field models offer an energy‐based approach that does not require predefined crack paths and automatically determines crack initiation, growth, and coalescence.

Abstract Triploidy is an effective tool for producing sterile fishes but often results in impaired performance in commercial aquaculture. In light of this, our study compared the physiological response to exhaustive exercise in juvenile diploid and triploid Arctic charr Salvelinus alpinus, a polar species with great potential for aquaculture.

Anatomy of spinal CSF loss in the American alligator (Alligator mississippiensis)
India ink introduced into the cranial cerebrospinal fluid (CSF) compartment of Alligator diffuses along the spinal cord and exits the spinal compartment using perineural flow, resulting in a prominent “ink cuff” forming at the base of the spinal nerve. In Alligator, the region of the ink cuff is drained by a small lymphatic vessel.

Psychogenic polydipsia in dogs – a review of pathogenesis, diagnosis and treatment
Polyuria and polydipsia represent a common clinical presentation in dogs and may result from numerous disorders affecting different body systems. Compulsive water consumption is characteristic of psychogenic polydipsia, a primary polydipsia disorder rooted in neurologic, behavioural or environmental factors.
