Overfishing in the Pacific Ocean has decimated bluefin tuna — the population is now less than 3% of what it was before commercial fishing began. A new study shows why conservation efforts aren't working: they were focused on the wrong part of the Pacific.

What they found: Bluefin tuna spawn in the western Pacific, where most commercial fishing takes place and conservation efforts have been focused. But, most younger bluefin tuna actually spend several years in the eastern Pacific before migrating west, so the lack of conservation efforts there is the most likely culprit for the failure to bring back the population.

"Stakeholders on both sides of the Pacific need to enact comprehensive, science-based management measures to rebuild the stock of bluefin tuna," the authors wrote in Science. Conservation groups and commercial fishing interests alike "need to better understand the life history of this fish in order to inform fishing management policies."

Why it matters: Crafting reopening plans gave tech firms a chance to bolster their leadership and model the beginnings of a path back to normalcy for other office workers. Their decision to pause those plans is the latest sign that normalcy is likely to remain elusive in the U.S.

Why it matters: These changes are providing an almost insurmountable advantage to big companies, which are positioned to come out of the recession stronger and with greater market share than ever.

College students overwhelmingly plan to return to campus this fall if their schools are open — and they claim they'll sit out the fun even if it's available, according to a new College Reaction/Axios poll.

Why it matters: For many, even an experience devoid of the trappings of college life is still a lot better than the alternative.
