Flowing electrons help ocean microbes gulp methane Posted: 18 Sep 2015 03:03 PM PDT Good communication is crucial to any relationship, especially when partners are separated by distance. This also holds true for microbes in the deep sea that need to work together to consume large amounts of methane released from vents on the ocean floor. Recent workhas shown that these microbial partners can still accomplish this task, even when not in direct contact with one another, by using electrons to share energy over long distances.

'Tree of life' for 2.3 million species released Posted: 18 Sep 2015 03:03 PM PDT A first draft of the tree of life for all 2.3 million named species of animals, plants, fungi and microbes has been released.
