The team behind this have proposed a pretty easy and sensible experiment. The article is terrible, but the theory of information having weight is pretty cool.

The idea that the probability chart for any given fundamental particle, has physical weight. The probability chart for any given particle interaction becomes a bit, and they have proposed an information 'particle' size.

The experiment is shooting an electron beam into positrons at CERN (through a moderator), and measuring the outcome. The team has proposed an expected outcome to support their findings.
