Behavioural and physiological responses of chacma baboons (Papio ursinus) to human‐induced mortality in anthropogenically modified habitat

People and Nature, Volume 7, Issue 8, Page 1865-1878, August 2025.
Abstract As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between ...

The Local Group Census: planetary nebulae in Sextans B

, 2002
Five planetary nebulae (PNe) have been discovered in the nearby dwarf irregular galaxy. Emission line images were obtained using the Wide Field Camera of the 2.5m Isaac Newton Telescope (INT) at La Palma (Spain).

Maximum Mass Limit of Generalized MIT Compact Star: A Theoretical Study of Thin Shell Dynamics and Gravitational Lensing

Fortschritte der Physik, Volume 73, Issue 8, August 2025.
Abstract In this study, the properties, equilibrium, and stability of compact objects within the framework of teleparallel gravity with the generalized MIT bag model are investigated. By incorporating the modified field equations, the influence of the generalized bag constant on the structure and physical characteristics of quark stars and neutron ...

Nutrient‐Synbiotic Complex Ameliorates LPS‐Induced Depressive‐Like Behavior via Modulation of Gut Microbiota and Tryptophan Metabolism in Mice

Food Science &Nutrition, Volume 13, Issue 7, July 2025.
Complex interventions significantly prevent the depression‐like behaviors. Nutrient‐synbiotic complex presents the more beneficial effects. Nutrient‐synbiotic complex modifies the composition of gut microbial community. Nutrient‐synbiotic complex improves the tryptophan metabolic homeostasis.

Polycyclic aromatic hydrocarbons in the dwarf galaxy IC 10

, 2011
Infrared observations from the Spitzer Space Telescope archive are used to study the dust component of the interstellar medium in the IC~10 irregular galaxy. Dust distribution in the galaxy is compared to the distributions of H$\alpha$ and [SII] emission,
