Disease in the developing world could be shown the red light by a
groundbreaking new discovery, researchers have said.
Medical and computing science students at Newcastle University have designed
a bacterium that glows red if pathogens - disease-causing micro-organisms -
are present.

If the bacterium is in the presence of harmless bacteria, it glows green.

Researchers said the simplicity of the design means it can be used in the
field with no need for sophisticated laboratories.

The bacterium can even be dried and broken down into spore form.

Dr Jennifer Hallinan, advisor and Research Council UK Academic Research
Fellow in Complex Systems, School of Computing Science, said: "This
represents our first step into the hot new field of synthetic biology.

"The students have found it quite challenging and it's really taken them out
of their comfort zone, but they've thoroughly enjoyed it.

"It is a tremendously exciting opportunity, both for the students
themselves, and for the University."

The six students, whose backgrounds range from computer science and
bioinformatics to microbiology and biochemistry, will pitch their idea at
the International Genetically Engineered Machines in Boston, US this
weekend.

The competition aims to bring together teams of students to design and
genetically engineer a bacterium to do something novel and useful.
