Disappointed to see a Fermilab publication throwing around weight and mass in the same sentence, such as "neutrinos must weigh less than 2 electronvolts". Further, it may be common in HEP to use natural units and thus eV is OK but in a (somewhat) lay publication, that really should stay eV/c^2 until natural units are introduced.
