Rotenone Induces Morphological Damage and Reduction in Catecholamine Levels in the Central Nervous System of the Ascidian Styela plicata

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Ascidians are invertebrates that occupy a key phylogenetic position as a sister group of the vertebrates. The organization of their central nervous system (CNS), with cortex and medulla, indicates a plesiomorphic character of the gray and white matter of vertebrates, making this group of animals useful for studies of neurodegenerative events ...

Staging concept for aging management: Definition, mechanism, and coping strategies

open access: yesVIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

And then there was us Et puis nous sommes apparus

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
In 1987, the academic conference ‘Origins and Dispersals of Modern Humans: Behavioural and Biological Perspectives’ was held in Cambridge, UK. Subsequently referred to as the ‘Human Revolution’ conference, this meeting brought together the most prominent academics working in the field of human origins, including archaeologists and palaeoanthropologists,

Full‐length transcriptome profiling of true bug mitochondrial genomes reveals the unique transcriptional regulation during insect evolution

open access: yesInsect Science, EarlyView.
The mitogenome was transcribed into complete primary polycistrons on both strands. The heteropteran mitochondrial transcription termination factor (HmTTF) functions as a bidirectional attenuator rather than a terminator, and co‐evolution of HmTTF and the binding sites was observed.

Cenozoic Tectonics Ignite Mitochondrial Codon Innovations Propelling Canid Body Size Evolution and Transcontinental Radiations

open access: yesIntegrative Zoology, EarlyView.
We decode mitochondrial genomes across all extant canids, revealing lineage‐specific codon optimization driven by altitude, predation, and body size. A tripartite framework integrates geological events, metabolic constraints, and adaptive radiation to explain carnivore evolution.
