Socio-economic hierarchies may be bad for health, even among people living in a relatively traditional, small-scale society in the Bolivian Amazon.

Inter-molecular cross-seeding between phenol-soluble modulins facilitates rapid and efficient self-assembly in Staphylococcus aureus biofilms revealing a complex molecular interplay between distinct phenol-soluble modulins orchestrating functional amyloid formation.

Neuronal serotonin release tunes transcription response times of Caenorhabditis elegans germ cells to promote the survival and stress resistance of future offspring.

The cyclic neuropeptide somatostatin binds to human Aβ1-42 through an interface that critically relies on a specific tryptophan, thereby blocking the propensity of Aβ to aggregate, a critical step in the pathobiology of Alzheimer's disease.

The presence of humans induces behavioral modifications in many large carnivore and ungulate species, restructuring spatiotemporal relationships between African predators and their prey.

From middle childhood to early adulthood, the preference to engage with novel choice options remained consistent, but aversion to reward uncertainty increased.

The mutual interaction between the basement membrane protein Multiplexin and the phagocytosis receptor Eater expressed by the immune cells drives the formation and maintenance of the hematopoietic tissues in Drosophila.

Synaptic silencing-induced homeostatic enhancement of presynaptic glutamate release is mediated by the postsynaptic retinoic acid-dependent brain-derived neurotrophic factor (BDNF) synthesis from dendritically targeted BDNF transcripts, leading to retrograde activation of presynaptic tropomyosin receptor kinase B receptors.

Genetic variants located in DNA repair genes and a reduced burden of somatic mutations protect the oldest living persons from age-related diseases, allowing an healthy aging phenotype.

Even when the primary visual cortical area is absent bilaterally from early life, the rest of a primate visual brain can develop and function normally to support day-to-day visual behaviour.
