Bacteria were the original masters of their domain, having the Earth to themselves for the majority of their existence, filling every environmental niche, nook and cranny, from mountain peaks to the thermal vents at the ocean's ...

Spores of Bacillus bacteria can survive for years in a dormant state, and then germinate in minutes. But it has long been unclear whether germination required protein synthesis, or cellular energy packets, which are known ...

Researchers from the Heidelberg University Biochemistry Center (BZH) have discovered a complex of four proteins that, much like a multi-tool pocketknife, serves as a knife, a file and a pair of scissors in the manufacture ...

Ribosomes, the molecular factories that produce all the proteins a cell needs to grow and function, are themselves made up of many different proteins and four RNAs. And just as an assembly line must be built before it can ...

What makes stem cells so interesting is that they are pluripotent: they have the potential to become any cell in an organism. Their ability to differentiate into any cell and be used to replace those that are damaged or ...

A growing, dividing cell uses most of its energy store to make its "protein factories", the ribosomes. An important player in their "assembly" is the exosome, a molecular shredding machine that breaks down excess ribonucleic ...
