This Viral DNA Infects Cells by Changing From a Solid to a Liquid

Two new studies are showing that viral infections are possible owing to a remarkable biological phase transition. The research shows that viral DNA transforms from a glassy solid to a fluid-like state when the conditions for infection are just right. The new insight could result in new antiviral therapies. » 10/02/14 3:40pm 10/02/14 3:40pm

Watch how this robotic-like T7 virus infects a cell

If there was any doubt that viruses are basically microscopic machines, let this recreation of a T7 bacteriophage infecting an ecoli cell put those reservations to rest. In this animated video, the virus can be seen unfolding its six phage tail fibers as it latches on to an unsuspecting bacterium. Once stable and… » 1/11/13 2:00pm 1/11/13 2:00pm
