Summary

Story summary

A study by researchers at the University of California, Riverside, and the University of Southern California shows that RNA splicing influences mammal lifespan.
The team analyzed splicing patterns across 26 mammal species and found lifespan aligns more with splicing regulation than gene expression.
The brain emerged as a key area for lifespan regulation with splicing events linked to longevity, while researchers will study environmental factors that influence splicing.
