COLOURFUL E. coli.
Scientists claim to have
genetically modified E.coli
bacteria to create “invisible ink”.
Published in Proceedings of the
National Academy of Sciences, the
researchers modified the bacteria
so that it glowed and was able to
express seven colours.
The colours then led to enabled
scientists to code the alphabet,
the numbers 1-9 and some
symbols into the bacteria.
According to the researchers
secretive people will, using this
technology, be able to code a
message into bacteria, grow it in a
“broth”, place it onto a white
“membrane” similar to paper,
then send their message.
The recipient will be able to read
the message after stamping it
onto a bacteria growth plate and
translating the colours into words,
numbers and symbols.
As an added security measure,
only the recipient’s growth plate
will contain the right chemicals to
develop the bacteria, and if the
membrane is intercepted and
grown into a message using the
wrong chemicals, the message will
be gibberish.
IS the world of nature and science
getting smaller?
In his keynote address at the
World Conference on Marine
Biodiversity, Associate Professor
Mark Costello from The University
of Auckland, told delegates that
there are just two million species
on earth, far fewer than
previously thought.
The statement is based on the
description of marine, terrestrial
and freshwater species recorded
in the World Register of Marine
Species and Catalogue of Life
databases.
According to the research
around 16 percent of the world’s
species are marine, with only 24
to 31 percent of earth’s marine
species, and 21 to 29 percent of
terrestrial species, yet to be
discovered.
