Researchers from Cambridge have developed Syn57 – an artificial E. coli bacterium that uses only 57 codons out of 64. The development could lead to the production of artificial proteins, new drugs and better control of industrial bacteria.

An artist's illustration of the protoplanetary disk surrounding the young star MWC 480. The ALMA telescope discovered the organic molecule methyl cyanide in the outer regions of the disk, where comets are thought to form. This is another evidence that organic chemistry is complex of the kind needed for life, it is universal. Figure: (NRAO/AUI/NSF)
