Yeah... it's a method from the last century. It's called transduction (http://en.wikipedia.org/wiki/Transduction_%28genetics%29), and it is routinely used at the microbiology lab. The new approach here is the idea of using it for communication. But communication needs to be both ways, and they implemented just one way. For making cells react to certain stimulus, it's way better to bioengineer them adding the corresponding membrane receptor and required pathway. And the problem with using phages in this case is, how do you stop them!? They will make the cells very inefficient.

Depending on the severity of your injured arm, maybe you could manage to tape your limb to one of these devices: http://www.catistore.com/sp3dusbmoby3.html You can operate 6 axis (move, rotation). That means moving + aiming in an FPS. Then, you could use your other hand with the keyboard. I don't know if this will work for you, since you didn't specified precisely the extent of your injury. For instance, I am an amputee. But I only lost 2 phalanxes in my left index finger, so the first sentence is a bit misleading.

Gold is a very good semiconductor, comparable to copper, with better corrosion resistance. High end connectors connectors have a thin layer coating of gold, especially for the transmission of analogous data. It has also good thermal transmission, and it is used for heat dissipators. It is also good reflector of radio waves, being used in the coatings of sats, astronauts and electronic warfare aircraft. So the price is a bit inflated, ok, but it will never fall below the price of say, copper.

Most genes are used to produce proteins. Samples of all the proteins present inside a living human cell are exposed on the cell's membrane, as part of the immune system machinery. (See Mayor Histocompatibility Complex http://en.wikipedia.org/wiki/Major_histocompatibility_complex) Those proteins can be targeted using homing peptides (think of it as a specific antibody) on a liposome (http://en.wikipedia.org/wiki/Liposome). That liposome can contain anything from drugs to viral RNA. Right now, you can make a solution with liposomes (or polymersomes), that when injected only kills the person if he/she has a certain trait. But I gess that is not a weapon of mass destruction... Anyway, making it a disease is another story. It could involve modifying the HIV virus, which already has a lipid bilayer just like a liposome. And then you have the problem of keeping that disease specific to the target population. And viral genomes tend to mutate at a very fast rate.

Hey, I work with junk regions! (satellite DNA) And I completely agree with you. But I see that centering on the variability of those few regions rather than sequencing a second complete genome will probably be better for health-care research. The project's title is completely misleading. That's for sure.

And if you don't like the billboard, you can close your eyes too. Just don't make any wheel corrections with your eyes closed! Seriously, even the billboards themselves are too invasive for my taste.
