Longer Lifespan Without a Reproduction Cost

March 04, 2019

Genetic manipulation that more than doubles lifespan also leads to better offspring - according to new collaborative research from the University of East Anglia and Uppsala University. Researchers studied a gene, known as DAF-2, which is associated with aging in roundworms (Caenorhabditis elegans). They found that by reducing this gene's expression, they could not only increase the worm's lifespan - but also improve the fitness of its offspring. It is hoped that the findings could one day help us stay younger and healthier for longer.
