BERLIN (AFP) — Indian and German scientists have said that a controversial experiment has “dampened hopes” that dumping hundreds of tonnes of dissolved iron in the Southern Ocean can lessen global warming. The experiment involved “fertilising” a 300-square-kilometre (115-sqare-mile) area of ocean inside the core of an eddy — an immense rotating column of water . . . → Read More: Iron Fertilization Will Not Help Global Warming

They produce domoic acid, a neurotoxin typically to blame for all sorts of marine vertebrate deaths. Alfred Hitcocks’s 1963 film “The Birds” dramatizes a bird attack incident blamed on domoic acid. Human consumption of shellfish that has filtered Pseudo-nitzschia leads to amnesic shellfish . . . → Read More: Nerve Toxins In The Deep
