In modern warfare coded messages are an important tool to ensure that units on the battlefield can co-ordinate their actions against the enemy and win the fight.
Scientists at UC Davis have found that bacteria use tiny protein messengers to co-ordinate their actions against victims and enemies.
In a study on bacteria feeding off rice-plants, a protein a called ax21 was found, enabling the bacteria to talk to each other in the event of an attack against the bacterial colony. The molecule is produced inside the bacteria and secreted, to tip off the other bacteria so they can line up in a phalanx, creating a bio-film surrounding the colony, protecting it against drying out or succumbing to antibiotics.
By working together and making individual sacrifice, they increase the survival-rate of the entire colony.

Polymer chemists have found a way to make almost any material carry an electric current, through a process called self-assembly. The new technology can be heated, frozen or drenched in jet-fuel without loosing it’s conductivity and repair itself if damaged.
The metal rubber can be used to make malleable and electrically charged aircraft wings, artificial muscles or wearable computers.
The new tech can be applied to almost any material through a simple chemical process, dipping the substrate material into a negative and positive chemical solution, imprinting it with electric properties.
Wearable technology and artificial limbs will be subjected to extreme wear and tear, just the reason why English school-boys have always used short-trousers. Little boys’ knees repair themselves, trousers do not.
Metal rubber might make long trousers fashionable in English primary-schools for the first time in centuries. If the material is broken or deformed, just run an electric current through, and it bounces back to it’s original form.

Albert, old boy. They can't touch you.
The Opera experiment at CERN has perhaps tickled the stress-hormones of the physics community. But they are probably not too worried, because they know they are the ones that are paid to figure it out anyway.

Perhaps velocity falls out of the context, following that velocity in the universe can only be determined by an objects’ relative motion to other objects in the same reference-frame (ie space-time.)
If one looks at the universe as a brane, then it may be so that these small elusive neutrinos can take a jump off the old brane and come back again shortly after. Thus departing for a few nano-seconds by our time, out of the space-time geometry and into a realm of physics that have been unobservable outside the confines of a piece of paper. Taking a geometrical shortcut outside the grasp of Einstein.
Einstein’s theories inherently admits not knowing the answer to this riddle. But he may very well be pointing us in the direction of it.
“I see far because I stand on the shoulders of giants.”
Albert Einstein did not live to see String Theory, and the world would most likely never seen it either if had not been for Einstein, and his revelations about energy – matter equivalence, and matter – space-time interactions.
On our particular layer in the Universe, Einstein is rock-solid.
