Biologists Program E. Coli To Patrol For Pathogens
MTorrice writes "When hospital patients develop nasty, antibiotic-resistant infections, the bacterium Pseudomonas aeruginosa is often the culprit. In a new approach to killing the pathogen, researchers genetically modified harmless Escherichia coli bacteria to detect and destroy P. aeruginosa. The E. coli spot a specific chemical released by the pathogen and then secrete a toxin to kill it (abstract)."
What could go wrong? You're worried about the wrong thing, my co-cowardly friend! Just think if somebody did invented machines capable of doing thousands, millions, or even billions of calculations a second. Then connect vast numbers of them together in some sort of network where information could be sent and received. We'd be one coding mistake, just one little "0" replaced with a "1" and BAM! Sentient calculating machines hell bent on destroying humanity.
Here we are (hopefully) harnessing it for our own safety.
Silence is a state of mime.
Why would (most) of the bacteria in our bodies want to disrupt the sweet gig they've got?
We work our fool polycellular asses off trying to maintain nice, stable, internal conditions, complete with nutrients and an immune system with a vested interest in kicking out the troublemakers...

That's basically what normal flora is.
The military funds far more than weapons R&D. I've worked on a project to develop insecticides against mosquitoes that was funded by the US military. There are no weapon aspects, it was to protect American troops against diseases (dengue, malaria, etc.) that some species of mosquitoes can spread. The military has funded things that seem off the wall, like marine biology research trying to figure out a why jellyfish light up in the wake of a ship. Naval aviators have found their way back to carriers by following the carrier's fluorescent wake, but the same could be used by an enemy and the Navy wanted a way to make it stop. Didn't work out, but there is some interesting basic research on jellyfish and Green Fluorescent Protein that was produced as a result. The military also funds vaccine and antibiotic research, research into new surgical techniques, prosthetics, renewable energy sources (ie biodiesel), and a lot of other non-weapons research.
Thanks for listing some of those things. I hadn't heard of the of jellyfish thing - that's neat stuff. The main reason I think it's good to point out what you did is it maybe can help counter the great amount of cluelessness amongst people who don't bother to look into or think about things. We live in a mental land chock full of buzzwords and phrases - nuclear, military, intelligence, cloud, etc., and I think it helps to clarify things.
This bit with the e. coli looks interesting; one has to wonder at just how more usefully it and similar organisms and techniques might could be used.
That is a great post, very informative.

Dude, E. Coli is like the Raspberry Pi of bacteria.
