WITH the right lighting and atmosphere, it is possible to take snapshots of
proteins during their most intimate moments—as they interact in the
processes of life. But like all still photos, this records just a single moment,
frozen in time. Now a team of researchers has found a way to make movies of two
proteins interacting.
Researchers typically use a scanning electron microscope to get pictures of
individual proteins, but you can only do this in a vacuum. Unfortunately,
biology doesn’t take place in a vacuum, says Mario Viani of the University of
California in Santa Barbara. So he…
