Smaller nucleoli slow aging, acting as a "mortality timer," while larger nucleoli lead to cell death by destabilizing rDNA. The secret to cellular youth may lie in maintaining a small nucleolus—a ...

Receptors are groups of specialised cells. They detect a change in the environment (stimulus) and stimulate electrical impulses in response. Sense organs contain groups of receptors that respond ...
