A bacterial enzyme enhances both energy metabolism and health across the life span of C. elegans and mice
In worms and mice, a bacterial protein boosted energy use and health without shortening lifespan.
Yang Liu, Zhijuan Hu et al.
A protein taken from bacteria can speed up how cells make energy without the usual damage that speeds up aging. In tiny worms and mice, this protein boosted energy production and improved health signs over the animals' whole lives. It did not shorten how long the animals lived at their longest.
Shown only in worms and mice, not yet tested in people.
