Bottom-trawling fisheries reduce carbon storage

Published: 29 October 2024
Bottom trawling in the North Sea disturbs carbon-rich sediments, releasing ~1 million tons of CO₂ yearly and weakening seabed carbon storage. Researchers urge protecting muddy habitats to combat climate impacts and guide EU restoration efforts.

Deep-sea corals are home to previously unknown bacteria with extremely small genomes

Published: 4 November 2024
Researchers discovered two new bacterial symbionts in deep-sea corals that survive with ultra-small genomes and no carbohydrate metabolism, possibly using host-provided arginine. The microbes may help coral immunity or nutrient cycling.
