Humanin Mitigates Aβ‐Induced Retinal Pigment Epithelium Injury via AMPK‐Beclin1‐Dependent Mitophagy

open access: yesAging Cell, Volume 25, Issue 7, July 2026.
Humanin (HN) enhanced the clearance of Aβ‐accumulated mitochondria in the RPE while preserving retinal function and RPE barrier integrity. HN activated AMP‐activated protein kinase (AMPK), leading to phosphorylation of ULK1 and Beclin1, which promoted the interaction between Beclin1 and Parkin and their translocation to mitochondria.

The current status of the New World monkey phylogeny

open access: yesAnais da Academia Brasileira de Ciências, 2000
Four DNA datasets were combined in tandem (6700 bp) and Maximum parsimony and Neighbor-Joining analyses were performed. The results suggest three groups emerging almost at the same time: Atelidae, Pitheciidae and Cebidae.

Behavioral Flexibility and the Conservation Value of Howler Monkey Populations in Small Habitat Patches

open access: yesAmerican Journal of Primatology, Volume 88, Issue 6, June 2026.
Standardized effect sizes of the relationships between predictor and response variables. Natural logarithms are denoted as “ln.” Open circles (blue outline) indicate mostly positive effects; solid circles (red filled) indicate mostly negative effects. ABSTRACT Species occupying small habitat patches and exhibiting behavioral and ecological flexibility ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,
