The U.S. Air Force is looking for companies with ideas for detecting and defeating drones that pose a security threat, and doing it through a competition in which developers will make their pitches at Northeastern’s state-of-the-art drone-testing facility on Wednesday.

On Saturday, a U.S. Navy destroyer collided with a Philippine container ship off the coast of Japan, resulting in the deaths of seven Navy sailors. Peter Boynton, co-director of Northeastern’s George J. Kostas Research Institute for Homeland Security, says there are still too many unknowns to pinpoint the cause of the crash, but notes that the ships’ pattern of damage suggests that the accident occurred when the two vessels were trying to cross paths.

The Transportation Security Administration is finding more firearms than ever at airport checkpoints. Is this a sign that the TSA is doing its job or an indication that more travelers are trying to board planes with these weapons in their bags? And what about “insider threats” among airport personnel? We asked an expert.
