Meet the tiny machines in cells that massacre viruses

When viruses infect the body’s cells, those cells face a difficult problem. How can they destroy viruses without harming themselves? Scientists have found an answer by visualizing a tiny cellular machine that chops the viruses’ genetic material into bits. Their research shows how the machine detects the intruders and processes them for destruction to protect cells and prevent the spread of infection….
