In clownfish, emerging social dominance triggers coordinated changes in growth, food intake, behaviour, and gene expression, revealing how social interactions and individual phenotypes may reinforce one another during the formation of dominance hierarchies.
Although large language models are sensitive to sentence structure, they process grammatical relationships differently from humans, raising important questions about the nature and limits of language understanding in artificial intelligence.
The light receptor CRYPTOCHROME promotes wakefulness during short winter-like days in fruit flies, revealing a seasonal sleep-regulatory mechanism that may provide insights into seasonal affective disorder.
The route Staphylococcus aureus takes into host cells determines how quickly it reaches the cell interior, multiplies and kills the cells, revealing a potential new target for tackling chronic infections.
Extinction risk can depend on traits and habitats at different stages of an animal’s life, suggesting that conservation assessments should look beyond adults to identify vulnerable species.
A hidden developmental programme allows worker ants to repeatedly regain simple eyes that were lost during evolution, revealing how dormant genetic networks can fuel evolutionary innovation.
