Scientists continue to explore ways we can live longer and ensure those lives are healthier. A new discovery of note in this field comes from experiments in fission yeast (an organism often used for studies of aging).

Researchers from Queen Mary University of London have been testing a new drug called Rapalink-1, building on an existing immunosuppressant called rapamycin that has been shown to extend the life of cells and rodents . In these new tests, Rapalink-1 extended yeast lifespan to a similar degree as rapamycin.

What's more, molecular analysis revealed that the drug increased the production of enzymes that convert a compound made by gut bacteria, called agmatine , into a variety of other chemicals.

Previous studies suggest agmatine can extend the lifespan of the microbe
