The synthetic bacteria contain a shorter genetic code with 57 codons rather than 64, freeing up space for further edits that might lead to new drugs or virus-resistant microbes ...

This work establishes a versatile platform for expanding the genetic code in mammalian cells, paving the way for advanced protein engineering and functional studies in complex biological systems.

Arrow worms, or chaetognaths, are strange ocean predators that have puzzled scientists for more than a century. They have ...
