Synthetic base pairs replicated in vivo; cardiac stem cells questioned; miniature neurotransmissions and synaptic development; neurogenesis and memory loss; STAP saga continues

For the first time, synthetic DNA base pairs are replicated within living bacteria.

Rewriting the genetic code can lead to a better understanding of how living cells work, and spawn new biotechnological applications.

For the first time, researchers have engineered a multicellular organism that incorporates a synthetic amino acid into its proteins.
