Will 2024 be a 'good year' for blimps?

Blimps are indeed part of this "Innovations" roundup, but it's the collaborative abilities of army ants that have led engineers from Northwestern University and the New Jersey Institute of Technology to speculate that the insects' behavioral principles and brains could one day be used to program swarms of robots. David Hu, professor in the School of Biological Sciences and the George W. Woodruff School of Mechanical Engineering (with an adjunct appointment in the School of Physics), is quoted regarding his research on fire ant raft constructions during flooding, comparing the insects to neurons in one large brain.
