First Digital Message Sent Using Neutrinos

MINERvA is one of world’s most sensitive neutrino detectors and yet, out of 10^13 neutrinos in each pulse, it detects only about 0.8 of them on average.

Nevertheless, that’s enough to send a message. The FermiLab team used a simple on-off protocol to represent the 0s and 1s of digital code and transmitted the word “neutrino”.

Not particularly practical, though the story notes there are potential applications, such as submarine communication. You would use neutrinos to reach regions inaccessible with EM radiation — you need a situation where you are leveraging the one advantage you have: penetrability.
