As someone who speaks a latin-derived language, "in vivo" and "in vitro" are immediately easy to infer from context. There's nothing about latin/greek that is pompous: we use words like "dentist" and "plumber" and any english speaking person knows what they mean. Personally, I believe english is the lingua franca of the world precisely because it has a large number of appropriations and thus a very large and diverse vocabulary. Rather than expecting specialists to water down their vocabulary to cater to the uninitiated, it seems more reasonable to expect that science journalists should instead learn said jargon and learn how to interpret studies and abstracts properly. I'd go a step further and even argue that a highly educated society ought to encourage and celebrate cross-discipline learning not just by media reporters but by every individual, rather than expect everyone to meet at a mediocre common denominator.
