A graduate admissions committee in a scientific field doesn't give two ****s if you can speak another language - they and anyone else in the field would be interested in your ability within your field of study (ie in this case not world languages). Other then that a second language isn't particularly valuable unless you're in a cognate field that studies communication like international relations, communication studies, speech language pathology, audiology etc. Add to that the fact that English is the lingua franca
with over 1.8 billion speakers in the world. Besides that quite a bit of scientific work boils down to mathematics - you know "the international language". Of course Latin might be useful in ecology/biology but who really wants to learn a dead language.
