Move beyond free radical theory of aging

iMetaOmics, EarlyView.
Free radicals play a dual, dose‐dependent role in aging. Low levels activate the key sensor adenosine 5'‐monophosphate‐activated protein kinase (AMPK), promoting cell survival mechanisms like autophagy and enhancing mitochondrial health. High levels, however, push AMPK to initiate cell death pathways, such as apoptosis. This positions AMPK as a central

Looking for Visitor’s Effect in Sanctuaries: Implications of Guided Visitor Groups on the Behavior of the Chimpanzees at Fundació Mona

Animals, 2019
The question of ‘if and how captive primates are affected by visitors’ has gained increasing attention over the last decades. Although the majority reported undesirable effects on behavior and wellbeing, many studies reported contradicting ...

Plasmodium malariae and P. ovale genomes provide insights into malaria parasite evolution [PDF]

, 2017
Elucidation of the evolutionary history and interrelatedness of Plasmodium species that infect humans has been hampered by a lack of genetic information for three human-infective species: P. malariae and two P. ovale species (P. o. curtisi and P.

Respiratory Syncytial Virus Under the Lens of Structure: From Prefusion Stabilization to Next‐Generation Immunotherapies

iNew Medicine, EarlyView.
This illustration integrates key concepts covered in the review, including high‐risk populations, viral structure, host entry factors, the replication cycle, and licensed antibody‐based prevention strategies. ABSTRACT Respiratory syncytial virus (RSV) is a negative‐sense RNA virus belonging to the genus Orthopneumovirus within the family Pneumoviridae.

Recent origin of low trabecular bone density in modern humans [PDF]

, 2014
Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body ...

Chimpanzee choice rates in competitive games match equilibrium game theory predictions

Scientific Reports, 2014
The capacity for strategic thinking about the payoff-relevant actions of conspecifics is not well understood across species. We use game theory to make predictions about choices and temporal dynamics in three abstract competitive situations with ...

Escaping Constraints to Innovate: Maternal Neofunctionalization in a HoxB4 Duplicate

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Whole‐genome duplication in Xenopus laevis generated duplicated Hox genes that are largely constrained in sequence and developmental expression. However, HoxB4L uniquely acquired maternal expression through cis‐regulatory and protein structural divergence, illustrating how gene duplication enables transcription factors to escape pleiotropic constraints
