Watch Out Whales, Humans Want Your Krill
Krill, those tiny members of the ocean’s planktonic community, have an importance disproportionate to their size. They are a vital food for whales, penguins and increasingly, humans. Demand for krill-based animal feed and 0mega-3 fatty acids is leading to a “gold rush” in the Southern Ocean off Antarctica.
Harvesting krill is the outcome of a decades-long trend of “fishing down the food web“. After humans decimated large oceanic organisms like tuna and swordfish, global fisheries have turned to smaller and less desirable species. Lobster, for instance, was once fed to prisoners, while cod was once so plentiful it was used as fertilizer. Now, fisheries are increasingly snapping up ‘bait fish’ like anchovies, mackerel and menhaden. The fact that commercial fishermen are now turning to krill, even jellyfish, indicates we may be scooping up the last and least tasty fish in the sea.

Plastic is a part of the earth’s ecosystem, but it’s a part that no one wants. At Harvard, scientists are looking to replace single-use plastic bottles, plates, and cups with packaging that…
Tiny Amounts of Alcohol Might Extend Life
A new study on the effects of cholesterol on the life span of Caenorhabditiselegans, a tiny worm often used in experimentation, resulted in some surprising finds. The life span of the critters was doubled. Now it turned out it wasn’t the cholesterol after all. The cause of the effect was set in motion by the solvent used to deliver the cholesterol. The solvent used? Alcohol.
