Making materials and robots that self-assemble

Self-assembly and tissue engineering are about copying nature at a more basic level -- how things grow and form. Self-assembly is a broad concept that promises to enable molecular-sized machines, robots that build themselves, and ways of growing replacement parts for humans.

Self-assembly is a key strategy for nanotechnology because it promises to make it easier to construct things at the size-scale of molecules. It is also a key strategy in building machines at the visible scale that repair and reconfigure themselves. And tissue engineering, which involves guiding nature in growing replacement parts for humans, could become a significant part of the medical tool kit in the next decade.

Nanowires are poised to become a fundamental building block of important technologies like computer chips and chemical sensors. Scientists have gotten good at growing nanowires; the main barrier to their widespread use is finding ways to control them so they can be arranged and positioned in bulk to enable practical manufacturing methods.

Making good on an old promise

Videoconferencing is a decades-old, seemingly simple idea that has struggled to live up to its potential. Advances in computer vision, projectors and screens promise to realize the dream of making videoconferencing a common and relatively lifelike experience.

Computer Vision

Advances in computer vision and image processing enable a pair of different areas: making machines that see as well as humans do, and making machines that see in ways humans can't.

In the realm of seeing in ways that humans can't, a camera that can pull off a classic magic trick -- reading a playing card facing away from the camera -- has advanced efforts aimed at collecting all of the visual information about a scene by sensing light scattered off objects within it.

The project, in addition to enabling the impressive card trick, combines a digital camera and a digital projector to show a scene from the point of view of the projector as well as that of the camera. The advances are a step toward using a camera to collect enough information to create views of a scene from any angle under any lighting condition. (Camera sees behind objects, TRN June 1/8, 2005)

Another advance gives computers the relatively simple ability -- for humans -- to glance at a desk top and recognize the printed documents lying on it. Combining this with computers' traditional strong suit of file management results in a system that can answer questions like Where is the third quarter budget report? with the information that the report is in the right hand pile four pages down. (Video organizes paper, TRN January 12/19, 2005)

Any needed repairs to humans could be made using these technologies in space.
Advances computing could even use electrostatic emitters to manipulate DNA to reassemble vital organs
with the help of nano-sized nurse cells injected into the blood.
