Scientists record a virus ‘prowling’ inside cells.

Now that scientists can capture the instant a virus takes over a cell in
three dimensions and real-time, we have a better idea of how diseases
spread throughout the body. Two and a half minutes in length, the nature
film shows a genetically sterile virus thousands of times smaller than a
grain of sand making its way along the wall of human intestinal cells in
search of an entry hole. Tracing these particles is exceedingly
challenging, not least because they are much smaller than the cells they
are navigating. However, understanding how viruses break into cells is
vital for developing new means of protecting against them.
