Review links loss of cellular identity to ageing-related tissue decline

A newly published review compiles evidence that cells across the body gradually lose their defined molecular identity as organisms age, with this drift appearing alongside known age-related functional decline in tissues. The paper draws on decades of research spanning cellular turnover rates, epigenetic memory maintenance, chromatin organization and stress-response pathways to build its case.

Study identifies protein linking calorie restriction to longer lifespan in fruit flies

Researchers studying dietary restriction in fruit flies report identifying a specific protein that appears to mediate the link between reduced food intake and extended lifespan. The finding, described in a new study, points to a molecular mechanism that may help explain how caloric restriction slows aging in this model organism.
