Morphological Changes in Direct Pathway Striatal Neurons in a Rat Model of Tardive Dyskinesia
Movement Disorders, Volume 41, Issue 1, Page 234-240, January 2026.Abstract Background Tardive dyskinesia (TD) and drug‐induced parkinsonism (DIP) arise from prolonged dopamine antagonist use. Although D2 receptor hypersensitivity in the indirect pathway is a proposed mechanism, the role of the direct pathway remains unclear.

Health Correlates of Extended Longevity in Captive Ring‐Tailed Lemurs (Lemur catta)
American Journal of Primatology, Volume 87, Issue 12, December 2025.Male and female ring‐tailed lemurs exhibit distinct patterns of age‐related change in certain serum chemistry markers. Photo by David Haring. ABSTRACT Captive primates maintained at accredited institutions can live extraordinarily long lives and, as a result, are useful models for understanding the physiology of aging. Many institutions monitor primate

An Observation of Coordinated Collaboration in Wild Brown Skua (Stercorarius antarcticus)
Ecology and Evolution, Volume 15, Issue 12, December 2025.We present the first video evidence of cooperative food processing in wild brown skuas (Stercorarius antarcticus) on the Antarctic Peninsula. Our observations show that pairs coordinated their actions over space and time, consistent with actively coordinated collaboration.

Close encounters of the friendly kind: pacific between‐group interactions in primates
Biological Reviews, Volume 100, Issue 6, Page 2257-2284, December 2025.ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.
