By Environment Correspondent Alister Doyle OSLO (Reuters) – Microbes are thriving in surprising numbers at the deepest spot in the oceans, the 11,000-metre (36,000 ft) Mariana Trench in the Pacific, despite crushing pressures in sunless waters, scientists said. Dead plants and fish were falling as food for microscopic bugs even to the little-known hadal depths, parts of the seabed deeper than 6,000 meters and named after Hades, the god of the underworld in Greek mythology, they said. …

Monitoring the levels of this fluorescence could be an easier way for scientists to monitor the health of coral reefs around the world, a new study finds, as these reefs are subjected to stress from climate change and other factors.
