Probing the composition of sub-millisecond rotating compact stars by r-modes instability [PDF]

, 2012
We investigate the implications of the r-modes instability on the composition of a compact star rotating at a sub-millisecond period. In particular, the only viable astrophysical scenario for such an object, wich might present inside the Low Mass X-ray ...

The variability of giraffe skull morphology

Journal of Anatomy, Volume 249, Issue 5, Page 1068-1086, November 2026.
What does giraffe skull shape tell us about their development and evolution? Abstract Giraffe (Giraffa spp.) are among the most unique and charismatic extant animals, largely due to their distinct morphology. The evolutionary and developmental origin of ossicones is a key factor in giraffid biology, yet other features building their characteristic head

Humans are not unique: difficult birth is common in placental mammals

Biological Reviews, Volume 101, Issue 5, Page 2214-2239, October 2026.
ABSTRACT Human childbirth is widely presumed to be uniquely difficult and dangerous compared to birth in other mammals. Tight fetopelvic proportions can result in obstructed labour and contribute to high rates of maternal and neonatal mortality. Ideas summarised under the ‘obstetrical dilemma’ have contributed to this assumption by explaining difficult

Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

Ecology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

New periodic variable stars coincident with ROSAT sources discovered using SuperWASP [PDF]

, 2007
We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables.

Misperceptions of charismatic species' conservation status: Zoo visits and virtual exposure shape perceptions of extinction risk

People and Nature, Volume 8, Issue 10, Page 3648-3662, October 2026.
Abstract Biodiversity loss is accelerating globally, yet species are not equally affected, and public perceptions of extinction risk often diverge from scientific assessments. Understanding what shapes public perceptions is critical for effective conservation communication, particularly in zoos, where many people encounter exotic and endangered ...

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Evaluating machine learning models for multi‐species wildlife detection and identification on remote sensed nadir imagery in South African savanna

Wildlife Biology, Volume 2026, Issue 5, September 2026.
This research paper investigates the efficacy of leading machine learning (ML) models for detecting and identifying ungulate species in African savanna using nadir imagery from unmanned aerial vehicles (UAVs). Traditional aerial counting methods, while widely used, suffer from significant limitations in accuracy and precision, in part due to human ...
