Shafaqna English- Scientists discover that basic sensory experiences like touch and smell cancel out the longevity benefits of dietary restriction. Research shows that gentle tactile cues suppress a key longevity gene that normally extends lifespan during limited food intake.
The study reveals that sensory inputs activate neural circuits that override genetic pathways responsible for lifespan extension. This means environmental factors may undermine the potential benefits of strict dieting, even when calories are properly restricted.
Researchers also find significant behavioral trade-offs in manipulating longevity genes. Worms with enhanced lifespan genes show reduced response to danger and food cues, suggesting that extending life may compromise normal behavior. These findings highlight the complex relationship between environment, brain function, and aging processes.
