This fall, UC Berkeley is launching a new $11.9 million center for researchers to design and test novel motors, sensors, batteries, and other mechanical components. What will set this center apart from most engineering endeavors is that none of the devices built there will be visible without an electron microscope. The Center of Integrated Nanomechanical Systems aims to develop a storehouse of mechanical components hundreds of times smaller than the diameter of a human hair. Physics professor Alex Zettl is leading the charge, having recently demonstrated a conveyor belt for ferrying atoms, the world's smallest nanomotor, and an oscillator based on drops of liquid metal that weight just one-quadrillionth of a gram.

Every Effort will have its Fruit.

Certainly these endeavors will have significant acheivements.

It is simultaneously ignoring what is going on at the eye level.

They might put a goggle over the snout of a large animal for fun in a circus and stop right there.

I would say they should put like some custom made 3-part cellphones (put under the simultaneous control of both the human and the canine) over the mouths, ears & paws of say a pack of dogs...and make them all reach a wellknown rendezvous from various locations within say 5 minutes without errors! In otherwords Animal-Networking.

Should upload huge amounts of data (say of some music) into the brains of a couple of crocodiles and download them back into the pcs again. Such a successful demonstration will be the forerunner of what we saw in Batman movie.

The above kind of things might be safe and equally productive at the same time when compared to building nanouniverses!

I would rather go for surround sound or focussed sound! And Cats. peace be on earth for them.
