Who wants jellyfish for dinner?

It's been said that as wild and readily-available supplies of everyday market fish like salmon, cod and halibut are depleted -- and the upper reaches of the marine food chain is removed -- we'll have to start eating our way down the food chain. It doesn't get much lower than jellyfish (already a delicacy in certain parts of Asia), which are becoming more and more plentiful as their predators disappear and excess nutrients from agricultural runoff makes it way into the oceans. Turns out that jellyfish explosions are becoming an epidemic in the Black Sea, ever since the mackerel population was overfished in the 1960s and 70s; now jellies can multiply with unchecked abandon, fed by animal waste and fertilizer runoff from farms.

A Very Brief History of Chamber Pots

Some of the oldest chamber pots found by archeologists have been discovered in ancient Greece, but portable toilets have come a long way since then. Whether referred to as "the Jordan" (possibly a reference to the river), "Oliver's Skull" (maybe a nod to Oliver Cromwell's perambulating cranium), or "the Looking Glass" (because doctors would examine urine for diagnosis), they were an essential fact of life in houses and on the road for centuries. In this video from the Wellcome Collection, Visitor Experience Assistant Rob Bidder discusses two 19th century chamber pots in the museum while offering a brief survey of the use of chamber pots in Britain (including why they were particularly useful in wartime).
