The article discusses the highlights of a meeting by scientists held at the Bella Centre in Copenhagen, Denmark, in March 2009.

The article discusses a research about bacteria-laced sediment from the sea floor in Aarhu, Denmark. It references the study by Lars Peter Nielsen of Aarhus University in Denmark and his team published in an issue of "Nature." Their evaluation of the hydrogen sulphide from the seawater suggested that bacteria several centimeters from the surface began breaking down the gas long before the reintroduced oxygen had diffused down to them. Nielsen thinks that this took place due to a network of conductive protein wires between the bacteria.
