• Administering natural substance spermidin stopped dementia in fruit flies
    Age-induced memory impairment can be suppressed by administration of the natural substance spermidin, a study in fruit flies suggests. Biologists were able to show that the endogenous substance spermidine triggers a cellular cleansing process, which is followed by an improvement in the memory performance of older fruit flies. At the molecular level, memory processes in animal organisms such as fruit flies and mice are similar to those in humans.
