Turning Discarded Lobster Shells Into Batteries

June 22, 2016 Canada, International News, Marine Science

Mark MacLachlan, of the University of British Columbia in Vancouver, has found a new way to produce batteries: the discarded shells of shellfish. Specifically, by using chitin, the substance that gives certain animals their iridescence (think the luster of the interior of an oyster shell). As reported by Hakai Magazine, Chitin can already be used for a variety of purposes, both medical and industrial. It can be used as biodegradable surgical thread, meaning sutures eventually disappear on their own. It’s can also be used to form a version of biodegradable plastic. Read the rest here 11:16

The New England groundfish debacle (Part III): who or what is at fault? Nils E. Stolpe/FishNet

It took me a while to decide how to most accurately describe the situation that has been visited upon the New England fishing communities that are and since colonial times have been dependent on the groundfish fisheries.

NILS STOLPE: The New England groundfish debacle (Part IV): Is cutting back harvest really the answer?

While it’s a fact that’s hardly ever acknowledged, the assumption in fisheries management is that if the population of a stock of fish isn’t at some arbitrary level, it’s because of too much fishing. Hence the term “overfished.” Hence the mandated knee jerk reaction of the fisheries managers to not enough fish; cut back on fishing. What of other factors? They don’t count. It’s all about fishing, because fishing is all that the managers can control; it’s their Maslow’s Hammer. When it comes to the oceans it seems as if it’s about all that the industry connected mega-foundations that support the anti-fishing ENGOs with hundreds of millions of dollars a year in “donations” are interested in controlling.
