At one time or another, most of us have played with a flipbook, using our thumbs to rapidly flip a series of pictures to create an illusion of movement.

Ribosomes undergo changes in conformational state, striking different, well-orchestrated poses that allow strands of RNA to be fed through the structure's two subunits where instructions carried ...

A new study has determined that bacteria can alter their ribosomes when they are exposed to antibiotics, which can change the structure of targets used by antibacterial drugs; this mechanism may be a ...

New tactics in controlling infection are sorely needed, with antibiotic-resistant bacteria expected to claim as many as 2 ...

The ribosome is a large assembly of proteins and ribosomal RNAs (rRNAs) that functions to translate messenger RNAs (mRNAs) into proteins. The ribosome catalyzes the assembly of amino acids into ...

Smaller nucleoli slow aging, acting as a "mortality timer," while larger nucleoli lead to cell death by destabilizing rDNA. The secret to cellular youth may lie in maintaining a small nucleolus—a ...

An exploration of the unanswered questions in how the molecular chaperone Hsp90 supports protein homeostasis, and how single-molecule techniques could drive future breakthroughs in answering them.

Due to its rigid structure, proline frequently causes stalls at ribosomes—the "protein factories" of the cell. All organisms use a specific factor to overcome these stalls. In bacteria ...
