You are missing it's main niche: fast prototyping, that shortens design time. The objects are not intended to be used, but to see an approximation of their shape.
And there is the matter of printing cost: ABS/PLA is cheap.
Sure, flying cars will be much better than ground going ones, and wheeled vehicles are a dead end. Maybe, but not it 5 years.

Let's see... a layer size of 40 microns, maximum speed of 250 mm/s, build volume of 21x21x21 cm for only 1200 euros the DYI kit (or EUR 1700 pre-built). It beats everyone else in every department. Period.
Ok, it is still missing a second extruder or hotbed, and printing is still an art that takes skill and patience, as with any of the 3D printers in this price range.
Disclaimer: I own an Ultimaker, oh yeah.

How silly I am! My mistake. And my point is weakened, but still valid.
Regulations in Argentina call for a maximum of "2 microbes / 100 mL". That is 0.02 microbes/ml and is correct (I hope this time it is!).
So at 10 microbes/ml = 1000 microbes / 100 mL the water from this lake is not allowed for dinking in Argentina.
I am a biologist working at a molecular biology lab. One test I did on water from a mountain river surrounded only by wildlife had 23 microbes / 100 mL, and that is clearly not a clean room! Another test on very stinky urban runoff water had 800 000 microbes per 100 ml.
At 1000 microbes / 100 ml, this lake has 43 times more microbes than a mountain river, but 800 times less than very stinky water.
If instead of ml it were ul, it would be 1 microbe / 100 ml, so it will be safe for dinking (provided there are no fecal coliform bacteria).

In my view, the most important thing about this is the fact that this could feed all the petrol based chemical industry that just needs petrol as reagents.
No, it's not about energy efficiency or carbon emissions. For that, you have fuels made out of sugarcane or corn that harvest all the energy they need from sunlight. Period.

My guess is that the unit of measure is wrong. It should be 10 microbes per MICROliter (not milliliter!), as 10000 microbes per microliter is actually very stinky water!!
Current regulations in Argentina allow for a maximum of 20 microbes per microliter in drinkable water (and zero enterobacteria).
The problem is that greek letters (eg: mu) are not easily displayed (as in this same post!).

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.
