Norway is responsible for salmon sushi

Japanese sushi did not include salmon until the mid-1990s because Pacific salmon was known to contain parasites. Norway, meanwhile, had an abundance of Atlantic salmon, which was safe to eat raw.

What revisiting a 1979 experiment reveals about ecosystem recovery after deep-sea mining

A 2023 study co-led by the National Oceanography Centre and the Natural History Museum, London, found that tracks made by the mining vehicle remained largely unchanged since 1979. Small animals, such as amoeba-like xenophyophore, were seen in the cleared areas, but sightings of larger animals known to live in the region were much rarer.
