Lysosomal activity in worms linked to transgenerational extension of lifespan

In the Wang Lab, it's not unusual for worms to live for a long time. HHMI Janelia Research Campus Senior Group Leader Meng Wang and her team study longevity. They've shown that by overexpressing an enzyme in the lysosomes of the roundworm C. elegans, they can extend the worm's life by up to 60 percent.
