WASHINGTON, - Rat cells grown onto microscopic silicon chips worked as tiny robots, perhaps a first step towards a self-assembling device, researchers working in the United States reported on Sunday.
They described a new method for attaching living cells to silicon chips. They then got the combined entities to move like tiny, primitive legs.
Writing in the journal Nature Materials, Jianzhong Xi, Jacob Schmidt and Carlo Montemagno of the University of California Los Angeles said it is possible to make such devices, starting with a single cell seeded on a specially treated silicon chip.
They used rat heart cells in one experiment and created a tiny device that moved on its own as the cells contracted.
A second device looked like a minuscule pair of frog legs.
A microdevice had two 'legs extending from the body at 45-degree angles; each leg had a 'foot extending at a 45-degree angle, the researchers wrote.
It may eventually be possible to grow self-assembling machines using the method, they said.

Ya know, this stuff is all kewl and great and everything, but - I wonder if we shouldn't think a bit more before making things half-biologic half-cybernetic that can self replicate. It... just... grinds on me. And don't tag me a non-techie simpleton, either - I write some pretty cool software (on occasion). I just wish for a bit more ethics review on some of these things.
I don't think ethics reviews are going to help us. I think a review of home EMP generators might be a better idea.
Resistance is futile; you will be assimilated!
On a serious side, I do agree with you. It seems that some scientists behave like children who have come across fireworks and want to ignite them all at once for jollies. I would like to see more sobriety in research scientists. They become giddy when they make some new discovery without stopping to consider the effects of the new discovery. Its like giving democrats a bankbook full of checks - same sort of silly recklessness.

The future is now... ;D

Vote fraud how-to's ping.
fascinating yet kinda scary, ping for later reading
D'ya think Licorice is involved? Say it ain't so!
Think postitively, we have kept from blowing up ourselves with nukes for nearly the last 60 years, maybe we'll get lucky with this 'dice roll' also.
That shi* scared the heck outta me. I saw a story on the discovery channel about it.
The realization of achieving the ability of altering reality at the molecular level does have that effect on some people.
The ability to arrange at the molecular level, is more than humankind can control. Science is always corrupted.
No governments and religions are always corrupted.
Science is only a tool.
A tool that is controlled my man. Man is corruptible. I think we are over-stepping our boundaries when we decide to develops such technology. Some things that can be created...shouldn't be. Nanotechnology is the one thing we should not perfect.
Usually it is a corrupt government or religion that says this so that they can keep the people ignorant and more easily enslaved under their jackbooted heal.
Some things that can be created...shouldn't be.
Like what, surgical technology that may have very well saved YOUR life.
Nanotechnology is the one thing we should not perfect.
Either WE perfect it or someone else will. Who do you trust more to do it, you, yourself, or someone else.
Ya think they're using RAT cells is an accident?
