Deep within our nerve cells, a molecule is at work that has no beginning and no end. Instead of a straight chain, as is common for most RNA strands, it forms a closed loop. Known as circular RNAs (circRNAs), these molecules are crucial for development, thought, and synaptic function, yet their high prevalence in neurons has long been a scientific mystery. How does the brain produce so many of them?
