Then the next challenge is to make a 3D printer that can print out the parts to make a 3D printer, but make sure there's no auto button.

Heart and Lung rhythms are regulated using systems known as reaction-diffusion systems. An entire system is represented by a grid of cells, with every cell is at a particular state with a mix of chemicals, typicall named A,B,C
Imagine if you stored your message as particular chemical levels, then ran a few thousand iterations - you would get a new unique state.
But it would seem extremely hard to roll backwards.
Some insect species like those giant hornets actually have random patterns that help identify individuals to each other.. Cows are also able to recognize each other due to the spot patterns - they do exhibit preferences to who they stand beside. My own theory is that snails can recognise each other using the stripy patterns they have on their shells. They would make the perfect bar code that could be read from any direction - a method that was patented in 1949 (http://www.scdigest.com/ontarget/12-12-18-1.php?cid=6548).
Before the discovery of micro-organisms, the belief was that illnesses were caused by bad spirits, objects and places like water-wells being cursed. In fact, there was something bad there - bacteria. Then they had the idea that blood-letting was one way of releasing the "bad spirits" from the body. In a way, it might have worked by reducing bacteria levels in the bloodstream.
Then there were the plague inspectors who wore boots, a long gown, hood and a facemask filled with herbs, spices and perfumes - a primitive version of a white-suit.
Once Newtonian and Maxwellian physics were known, it took researchers 200 years to find applications for those formulae. Batteries, electric circuits, lamps, photo-diodes, speakers, microphones, magnetic tape, magnetic disks, motors, cameras, video camcorders all came from that knowledge.
If a bug lands or even flies past an area of white hair, it becomes immediately noticeable to fast-moving predators like birds.
Every discussion about the best places to work has always brought up the following: the size of homes, property taxes, quality of education, gang crime, homeless levels, commute times as well as political and religious beliefs.
Businesses will also locate to where there are the most qualified workers at the lowest rate.
MP's in Scotland did the same with dentistry. They closed the Edinburgh dental school because in the MP's words "it looked a bit tatty". Over time this led to a shortage of NHS dentists because they all moved into private sector because of the opportunity to earn more money.
I though the Nintendo games (Super Mario 64, Ocarina of Time) started off in parallel steps as you explored each level to find keys and unlock other levels. But eventually after figuring out the optimum sequence of completing levels (get the flying hat first, then get the invisibility hat, get the ten keys, get the skulltulas), then the game becomes linear.
Wouldn't an external USB drive be more practical? You can even make your own by simply buying a $10 case and 2.5" disk drive. Anything up to 500 Gigabytes of storage in your pocket.
You can shift it by +/- 180 degrees. That's good enough for a sinusoidal wave.
Given the magnitude of energy involved (every level on the Richter scale is 10x the one below itI think it would be easier to build floating cities like Buckminster suggested. Build a skyscraper frame using a hollow superstructure, get enough sealed air in the superstructure and you actually end up with a structure that will actually float in the air due to differences in air density.
In London, there are enough taxis in the area, that all you really need to do is raise your arm and hail a cab, when ones passes with a "For Hire" sign.
You couldn't make an app that simpler. Some hotels and conference center receptions have a hotline telephone straight to the taxi cab office.
If the taxi cab dispatch offices brought out there own "app", they could cover every other part of the city.
By that logic, asking a friend or relative if they could give you or someone else a ride would constitute an illegal transaction.
Not so long ago, many Californian toll booths would only cars to travel across for free if there were two or more passengers, and they were actively encouraging ride-sharing to reduce traffic loads.
I would imagine tobacco or nicotine constricts blood vessels, and gives the white blood cells traveling along the lining of those blood vessels more chance of detecting and trapping the West Nile virus particles.
Brain size is larger than the theoretical size given the body mass. But most of the brain is used to manage body function with only a small area doing the actual logical thinking and planning. That's larger that the theoretical size. So they must have some logic there to handle the concepts of tubes, tunnels, sticks, pebbles. Given that they feed on insects and just about anything else that lives in trees, they'd have evolved to figure out out to get them out of holes in trees.
