Researchers found that exposing worms to mild stress early in life reprograms how their cells manage fats and energy, which protects them from harmful protein clumps that accumulate with age. This protection works through a protein called HSF-1 that gets activated during development and permanently changes how the worms' cells burn fat for energy. The discovery shows that surviving stress in youth creates a metabolic shield against brain diseases like Alzheimer's that involve toxic protein buildup.
