Chinese researchers came to the rescue and created a material just 5/16 of an inch thick that can safeguard stealth planes against UHF detection. The material tunes itself to a range of detection frequencies, protecting against a large swath of radar scans. What's even more amazing? They published this seemingly top secret invention wide open in the Journal of Applied Physics .

    Are they publishing it because (1) they have something better, (2) they have figured out a way to beat it and hope we will use it, or (3) they were simply incompetent?
