When a soldier in good mental health becomes homicidal or a government employee abuses access privileges to share classified information, we often wonder why no one saw it coming. When looking through the evidence after the fact, a trail often exists that, had it been noticed, could have possibly provided enough time to intervene and prevent an incident.

With support from the Defense Advanced Research Projects Agency (DARPA) and the Army Research Office, researchers at the Georgia Institute of Technology are collaborating with scientists from four other organizations to develop new approaches for identifying these “insider threats” before an incident occurs. The two-year, $9 million project will create a suite of algorithms that can detect multiple types of insider threats by analyzing massive amounts of data — including email, text messages and file transfers — for unusual activity.

*Study Finds Connection between Atmospheric Events and the Deep Ocean*

Researchers from Woods Hole Oceanographic Institution (WHOI) and their colleagues have discovered that massive, swirling ocean eddies–known to be up to 500 kilometers across at the surface–can reach all the way to the ocean bottom at mid-ocean ridges, some 2,500 meters deep, transporting tiny sea creatures, chemicals, and heat from hydrothermal vents over large distances.

The previously unknown deep-sea phenomenon, reported in the April 28 issue of the journal Science, helps explain how some larvae travel huge distances from one vent area to another, said Diane K. Adams, lead author at WHOI and now at the National Institutes of Health. (more…)
