High‐altitude headache: Insights into pathophysiology and potential treatment implications
The Journal of Physiology, EarlyView.Abstract figure legend High‐altitude headache occurs during prolonged exposure to low oxygen, such as during ascent to high altitude. Several risk factors increase its likelihood, with the degree of hypoxia, often driven by rapid ascent to greater altitudes, being the most prominent factor.

The Journal of Physiology, EarlyView.Abstract figure legend In lowland mammals that ascend to high elevation, hypoxia‐induced changes in the pulmonary circulation can give rise to hypoxic pulmonary hypertension (HPH) and associated right‐ventricle (RV) hypertrophy. Andean mice with broad elevational ranges have greater heart mass relative to body size at higher elevations, but they ...

The Anatomical Record, Volume 309, Issue 12, Page 3588-3602, December 2026.Abstract Factors varying along elevational gradients impose strong aerodynamic and physiological constraints on powered flight, yet the internal microanatomical variation associated with elevational context in animals under such conditions remains poorly understood.

Why Anthropologists Should Study Dogs
Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 4, December 2026.ABSTRACT While primates have traditionally been a focus of evolutionary anthropologists, the domestic dog represents a valuable complementary model due to its long shared evolutionary history with humans. The advantages of studying dogs are particularly evident in four key areas: (1) analyzing evolutionary adaptations, (2) understanding humanity's past,

From Physiology to Bioheat Simulation: A Data‐Driven Framework for Core Temperature Initialization
Heat Transfer, Volume 55, Issue 8, Page 5198-5228, December 2026.ABSTRACT Accurate initialization of core body temperature is a critical yet often overlooked component of bioheat transfer models, particularly when such models are applied to heterogeneous populations and real‐world environmental conditions. Conventional bioheat simulations typically rely on fixed or idealized core body temperature values derived from

Debittering Methods in Lupinus Species: A Comprehensive Review
Legume Science, Volume 8, Issue 4, December 2026.ABSTRACT Lupinus species (spp.), commonly known as lupins, represent a promising source of plant‐based protein and bioactive compounds for food applications. However, their utilization in food products is constrained by the presence of quinolizidine alkaloids, which impart characteristic bitterness and pose toxicity risks.
