A new way for scientists to interact with and understand the structure of
important biological molecules critical to human health is now available. Called
iSee, it’s now possible to interactively fly over, zoom into and dive through 3D
visualisations of these molecules in atomic detail.
 

Ultrafast, light-sensitive video cameras are needed for observing high-speed events such as shockwaves, communication between living cells, neural activity, laser surgery and elements of blood analysis. To catch such elusive moments, a camera must be able to capture millions or billions of images continuously with a very high frame rate. Conventional cameras are simply not up to the task.

ALBUQUERQUE, N.M. —Cells are expected to respond defensively when an
