Supercomputers help supercharge protein assembly

Red blood cells are amazing. They pick up oxygen from our lungs and carry it all over our body to keep us alive. The hemoglobin molecule in red blood cells transports oxygen by changing its shape in an all-or-nothing fashion. ...

New tool allows scientists to catch elusive protein in action

Like many of the processes that drive a cell's basic functions, those enabling the splitting of a newly-replicated cell into two, shown above, happen quickly. So quickly, in fact, that scientists often have a hard time pinpointing ...

Structural insights into tiny bacterial harpoons

New research sheds light onto how different bacterial species can build complex nano-harpoons with different protein building blocks. Bacteria use these harpoons called Type VI secretion systems to inject toxins into nearby ...
