rn when traces of arsenic are escaping from areas like mine workings, industrial chemical facilities, or even laboratories, alerting us before pollution manages to get into watercourses or drinking water supplies. We could also use it to test newly drilled wells in countries like Bangladesh where water supplies are known to be contaminated," said Thomas Osborne.

Many organisms, including all plants and animals, ultimately get their energy from the sun via photosynthesis. But over the last few decades scientists have discovered more and more microbes that can get their energy directly from breaking down chemical bonds. This enables them to survive in extraordinary and dark environments such as deep inside the Earth or at the bottom of the coldest, deepest oceans, where previously no life was expected to exist at all.
