NewsBacteria flourish in plumes of deep ocean volcanoes
Deep down in the ocean at tectonic plate boundaries, hot fluids rise from so-called hydrothermal vents. The fluids are devoid of oxygen and contain large amounts of metals such as iron, manganese or copper. Some may also transport sulphides, methane and hydrogen.

NewsClimate change could make High Arctic fertile ground for emerging pandemics
Melting glaciers increase the risk of viral spillover, suggesting the impact of climate change could lead viruses to infect new hosts in the Arctic, according to researchers at the University of Ottawa who performed a novel genetic analysis.
