In the latest in a series of stunning advances, a team of structural biologists has unveiled the most comprehensive view yet of one of the cell's most critical components: the ribosome. Science reports online this week ( a molecular view of a complete bacterial ribosome, down to 5.5 angstrom resolution. Although that resolution is not high enough to discern the positions of individual atoms in this giant complex of proteins and RNA, biochemists say it represents a huge step forward.
