Evolution
A
newly discovered bacterium at the bottom of the sea forms living
electrical cables that transmit chemical reactions over large distances.
While studying sediment from a past experiment, researchers at Aarhus
University in Denmark discovered variations in the chemical composition
of the samples that was happening too rapidly to be explained by a
simple chemical reaction. The source was found to b
e
a bacteria in the family Desulfobulbaceae that although identified
through DNA analysis, seem so different from any known member of that
family, scientists suggest a new genus may need to be considered.
Described in the paper by Pfeffer et. al, in Nature, the multicellular
bacteria, appears to behave much like electrical cables & is able to
conduct electricity over distances well beyond its size. By disrupting
their electrical abilities, scientists were better able to examine just
how they seem to produce electric current.
No bacteria were known to
transmit electricity across great distances until this discovery that
will reshape our views on how life forms interact with the environment
to survive in the deep sea.
