Scientists at IBM are conducting research into arranging carbon nanotubes-strands of carbon atoms that can conduct electricity-into arrays with DNA molecules

Once the nanotube array is meticulously constructed, the laboratory-generated DNA molecules could be removed, leaving an orderly grid of nanotubes. The nanotube grid, conceivably, could function as a data storage device or perform calculations.

Potentially, DNA could address, or recognize, features as small as two nanometers. Cutting-edge chips today have features that average 45 nanometers.

Alright readers, get ready to have your minds proverbially blown!Imagine you are shopping in a grocery store,strolling through the aisles, when all of a sudden the cereal begins talking to you.You step back, and look around.No one else seems to notice.You move forward again and hear the commercial persuading you to select and purchase Lucky Charms.Have you finally lost the last little hold you had on sanity?Or is it a hypersonic sound beam, intended for your ears only?

Chances are, in the near future, supermarket shelves will be lined with these sneaky sound systems, but they aren’t just for use in advertising.This ultra-cool technology remotely transfers sound waves in tightly focused “columns” of sound.Once directed to and landing on any surface, (ie. ceilings, floors, walls, paintings, sculptures, advertisements, or even people!) they instantly become a source of sound.The sound waves can then be processed and heard by only people in the direct path of the audio.Surprisingly, the sound seems to come from inside the head, as it acts like a speaker while transmitting the sounds to the brain.
