The Pacific Northwest National Lab, part of the Department of Energy, says the Pentagon's computers experience more than five thousand cyber-attacks a day.

Now the lab is working on a unique new way to fight cyber-threats with what it calls 'digital ants' that can digitally scurry through a network, cleaning up threats before they occur.

The so-called "ants" can follow a virtual "trail" to the source of problems and retrieve information.
