Comprehensive view of the status of Atlantic bluefin tuna

Bluefin populations on both sides of the Atlantic Ocean have declined precipitously since 1950, according to a new study. The model estimates the number of Atlantic bluefin tuna remaining in the ocean and projects future population sizes based on alternative management scenarios. The new model is revolutionary in its ability to account for population overlap (mixing) of this highly migratory...

"I propose to investigate the idea that light travels in little bits," one might say. "I will explore the possibility that time slows down as things speed up," goes another. Imagine what comments these would have elicited from reviewers...
