Homomorphic encryption is pretty amazing. What they're proposing in this article is a bit like having a computer analyze an encrypted novel and determining which sentences were grammatically incorrect--without even knowing what the plaintext sentences were!
I thought this post was incredibly well written, starting with the title. The title is captivating and draws readers in by suggesting a solution to a common annoyance. The article also addresses the bigger scientific achievement: this scanner may be useful for medical purposes such as measuring glucose levels or cancer cell levels at tumor sites. The article provides sufficient, interesting information while creatively tying in witty humor.
