Aeon’s featured videos are always stimulating and informative. This one is also eerily beautiful in time-lapse of sea stars and proboscis worms (and large numbers of tiny insect-like crustaceans) feeding on the corpse of a seal in the Arctic Ocean.

Growing up in the Deep South meant dealing with the heat in summer (well actually, from March through October in Alabama.) When we moved north to Virginia in 1974, I thought surely we had left 90-90 temp-humidities behind.
