A range of experiments suggests that creatine, a molecule known for recycling ATP in muscle and brain tissue, may also function as a neurotransmitter in the central nervous system.
An unexpected interaction between a long non-coding RNA locus and a genetic insulator called Fub-1 has an important role in gene regulation during development in Drosophila.
Experiments on worms suggest that a statistical measure called the G matrix can accurately predict how phenotypes will adapt to a novel environment over multiple generations.
