Alternative splicing linked to mammal lifespan
A study in Nature Communications compared alternative splicing across 26 mammal species (lifespans 2.2–37 years) and found splicing patterns better predict maximum lifespan than gene activity; the brain shows many lifespan-linked events controlled by RNA-binding proteins.
Light controls a calcium-powered protein engine for artificial cells
Researchers adapted a ciliate calcium-pulse strategy to make a protein network that contracts when calcium is released by light. The light-controlled system can repeat cycles, move tiny particles and may help synthetic drug delivery.
