identifying if a single molecule of explosive is present. MIT researchers created a carbon nanotube with a bee venom-based sensor,
designed to detect traces of explosives. If commercialized, it could one day improve the security at airports
when the bee venom peptides target molecules found in explosives. Since the proteins reacted differently,
depending on the types of molecules found in explosives, the scientists identified a finger print that is unique for each of the explosive chemicals they exposed it to,
including pesticides. MIT professor Michael Strano said in a statement: â Å Compounds such as TNT decompose in the environment,
creating other molecule types, and those derivatives could also be identified with this type of sensor.
Because molecules in the environment are constantly changing into other chemicals, we need sensor platforms that can detect the entire network and classes of chemicals, instead of just one type.
If the sensors make their way out of the lab and into the real world, they would be more sensitive than the spectrometry-based systems that are used currently to detect explosives in the air.
In the future, let's hope a single-molecule sensor can stop someone like Umar Farouk Abdulmutallab A k a. the underwear bomber from slipping through security.
Until then there's always the naked scanners at airports -which is in itself, a touchy subject.

To demonstrate, Australian researchers made a Bose-Einstein condensate (BEC) of rubidium atoms. A BEC is a substance that occurs
it can instantly freeze certain particles it comes in contact with. The researchers then aimed a beam of rubidium atoms at the condensate.
Instantly chilled, the atoms in the beam also dropped to their lowest state, getting rid of the extra energy by giving off a burst of light.
Astonishingly, that light contains all the quantum information needed to reconstitute the atom. Aim it at another BEC,
and whatever atom it strikes takes on the quantum state of the original atom. In effect, an atom at the transmitting end has disappeared
and been reconstituted at the receiving end. There is still an atom at each end but the quantum oeidentity has moved from one to the other.
It is a long way from teleporting a few individual atoms to sending people from the Enterprise to a planet surface.
