SEPT 25 - Molecular Technology: Giant Amoebas Invade Cities?‏

Dear Friends,
Click the link if you don't receive the images.
Love and Light.

Appearing from seemingly nowhere, huge amorphous blobs congeal on skyscrapers and bridges... eating the structures, ripping them apart beam by beam, from the top down in some bizarre slow motion choreography, stacking the construction materials in neat piles around their consumed victims. Soon, whole buildings are razed to the ground, surrounded by their own components.

Has science unleashed some uncontrollable mutant, destined to devour our cities and infrastructure? Is this a motion picture? Yes, but a movie run backwards.

Seen from the beginning (in forward time), trucks arrive at a hole in the ground dumping structural materials to the side. A few special trucks appear loaded with solid rectangular cargo Suddenly these featureless cargoes become animated, break into individual cubes and "pour" themselves off the flatbeds to the ground by sliding over and around each other. Now a chunky blob, the mass raises itself from legs made of its own cubes, while cubes at the top slide over the bottom cubes, then down the leading edge to.make more legs as back legs withdraw into the mass. The monstrosity "walks" over by two other off loaded blobs. The blobs congeal into a larger mass then heads for a pile of steel I-Beams.

From inside the creature, stubby arms appear, sliding over the cubes' flat surfaces, heading towards the steel. Great numbers of beams are hoisted from the ground and elevated to the top of the mass as other arms slide down for more. Then, the whole monster morphs and pours down the hole with the beams. From the ground, one by one, beams appear vertically in a symmetrical pattern and other beams are attached crosswise by arms with whining torque wretches.

What is going on? What are these things? They are Fractal Shape Shifting Robots. You are witnessing the birth of an age called "Digital Matter," where units of matter are controlled discreetly, like computers treat bits of information.

The New Unlimited Machine
A simple can opener or a complex asphalt paver are both single purpose machines. Ask them to clean your floor, or build a radio tower and they "stare" back blankly. A computer is different. It is a multi purpose machine-- one machine that can do unlimited tasks by changing software... but only in the world of bits and information.

Fractal Robots are programmable machines that can do unlimited tasks in the physical world, the world of matter. Load the right software and the same "machines" can take out the garbage, paint your car, or construct an office building, and later, wash that building's windows.

Fractal Shape Shifting Robots look like "Rubic's Cubes" that can "slide" over each other on command, changing and moving in any overall shape desired for a particular task. A "Tool Kit" of mobile, programmable arms for manipulating beams and construction material as well as welders, cutters, power wrenches etc. can attach themselves where needed on any cube surface. They work in large masses and cubes appear identical to each other. From a distance they may resemble an industrious amoeba as they construct... without traditional human labor, 24 hours a day, in any weather.

These cubes communicate with each other and share power through simple internal induction coils (or surface contacts in some models), have batteries, a small computer and various kinds of internal magnetic and electric inductive motors (depending on size) used to travel over other cubes. Construction cubes are big, but utilize smaller cubes to slide into "tight spots" as needed.

Self sustaining systems and self-assembly of large and smaller cubes is a goal that could drop cost dramatically and enable successive generations of robots exhibiting greater industrial utility. When sufficiently miniaturized (below 0.1mm) and fabricated using photolithography and E-Beam methods, the machines may exceed human manual dexterity and could then be programmed to assemble complex fractal aggregates that maintain the photolithographic and E-Beam equipment needed for smaller generations-- perhaps to the molecular scale... Nanotechnology.

Interestingly, the more cubes in a mass the more computers communicating with each other enabling "smarter" behavior. When not engaged otherwise, a million cubes could be contracted out from any location utilizing the internet, as a very powerful massively parallel supercomputer.

Basic concept of a fractal robot

The bricks are like Lego bricks in that they snap together to make a new shape. The bricks have interior motors that allows them to slide around under computer manipulation and create new shapes similar to the way kids build toy houses or toy bridges. This gives us 'Digital Control of Matter'. To make the machine 'fractal', special bricks have half size plates on one face that allow half size bricks to join. These in turn can have quarter size plates to attach quarter size bricks and so on like the diminishing branches of a tree, until we get to microscopic bricks.

The smaller the bricks, the finer the control we have over this 'digital matter'. Large bricks are electromechanical robotic devices, but as they diminish in size they will be fabricated using micro-machining and chip manufacturing techniques. Below 100 microns, they can use electrostatic motors until we get down to cubes of nano dimensions where the individual atoms become too big. At these scales, as our knowledge of surface chemistry improves, the robotic cubes will be able to interface directly with molecules opening up new avenues for exploring the manufacture of nanotechnology devices.

Presenting, Fractal Shape Shifting Robots, Programmable "Digital Matter"
For the last year, British engineer Joe Michael has been demonstrating 12-inch wide prototype robotic "cubes". They work, and are built with "off the shelf" components and a screwdriver. This same basic cube design can be scaled up to meter size for construction use, or scaled down in generations exhibiting greater industrial value and may be termed as macro (hold in your hand) sized "nanorobot" prototypes, possessing AND performing many of the desirable features of mature nanomachines (as described in Drexler's, Engines of Creation, Unbounding the Future).

Michael is head of *Robotic Construction International. Dallas based *Zyvex Corporation was the first nanotechnology company with the specific goal of developing the Molecular Assembler (a device that can build with individual atoms and led to self replicating machinery and consumer goods). Zyvex is taking what is generally known as a "Bottom Up" approach to developing an assembler, building components with atoms and molecules and are some 5 -10 years away from the first "breakthrough."

The advantage of Michael's "Top-Down" approach is that useful products can be developed from existing prototypes in less than two years. Consider Michael's next technology demonstration under development right now: Two large Plexiglas aquariums are set parallel to each other, 24 inches apart (this is an arbitrary number and could be 24 feet). Towards the top of the first aquarium, a hole is drilled and fitted with a tube leading to a hole in the second aquarium. Now both are connected.

On the floor of the first aquarium, several feet from the top-- sits a large group of three inch cubes, arranged in a neat pyramid. Some of the cubes have stubby, electrically powered grippers, held on the cube's featureless surface by internal electromagnets. Surrounding the cubes is a box frame made of model I-Beams that snap together at the ends. This skeletal box of I-beams is representational of construction elements used for assembling a toy train bridge trestle, or the structural members of a skyscraper.

On command, the "pyramid" begins to move over its bottom cubes towards one corner of the box. The overall shape changes as cubes slide over each other, reaching up and snaps the top joint, while cubes at the bottom do likewise. "Gripper" cubes slide with the disassembled beams in tow, and release them on the aquarium floor. The process is continued until all the beams are free.

Then, looking like that chunky amoeba, the mass of cubes change shape dramatically, as they slide over and up each other "crawling" towards the connecting tube above. The mass gets thinner as it gets longer, heading north. The first few cubes reach the opening and the outer line of traveling cubes shift motion 90 degrees and start entering the tube.

After enough cubes have entered the tube to anchor a hoist of the remaining mass, gripper cubes grab individual I-beams and haul them to the top, then rotate the beams to enter the tube head first and disappear. After the last beam, the remaining cubes are hoisted by cubes at the top, and the whole mass disappears from the first aquarium. In the second aquarium, a group appears from the tube descending down the glass in a line to form an elevator for the mass.

Beams appear and rotate, then descend to a forming base of cubes. Once all the cubes are out and down, the mass begins reassembling the box, starting from the ground up. After the box of beams is complete, the cubes retreat to the center and again, form a pyramid.

This process can be repeated until the batteries drain, or indefinitely if supplied with recharging induction coils in the floor of the aquarium.

A structure normally requiring millions of dollars of labor can be constructed with this equipment, working tirelessly-- 24 hours a day in any weather, attaching beams in parallel to finish a job in a fraction of the normal require time-- then go on to build again. The whole mass can literally "walk" to the next job site. This is Robotic Construction International's first commercial application of Fractal Robotic technology.

Other "large" cube applications include modifying the technology for the installation of masonry or marble facades, windows, wiring, air and plumbing. Emergency aircraft runways could be erected by programming these robotic cubes to arrange themselves in flat masses of plates. If cubes became damaged, they could be automatically discarded and replaced by the other cubes Such temporary airstrips can be carried on ship where they are "dumped" into the sea, and "walk" themselves to land. Minefield clearing cubes could run about autonomously keeping tack of location with satellite navigation, brimming with sensors sniffing explosives, detecting magnetic fields, using ground penetrating radar and even X-Ray and Gamma-Ray spectrography (bombard the ground and see what bounces back).

Smaller cubes get interesting. A large number of tiny cubes, possessing much computer power could be a great childrens toy, morphing into letters, speaking to and teaching kids to read-- later, picking up the kid's room and, if needed, walking the dog. How long before cubes become tireless indispensable servants?

Like many inventions, all the parts were already "on the shelf"-- it just took someone to put them together. The large 3' heavy construction models (first commercial application) will be a "gentle" introduction to the world of "Digital Matter." These things come with "tool kits" including "stick on" arms to manipulate materials. When cube assembly by other cubes drops price dramatically and the use of older generation chip facilities start pumping out masses of sub-millimeter generations, also assembled by other cubes... things could get interesting. The engineering path is clear.

Remember the "bad guy" robot in Terminator-2... what's the difference?

WASHINGTON (Reuters) - Researchers have found a way to target cancer cells by injecting tiny particles that will attack only the diseased cells while leaving healthy cells unscathed, according to a study released on Monday.

A team of researchers working at MIT and Brigham and Women's Hospital in Boston laced tiny particles with lethal doses of chemotherapy and when injected they targeted cancer cells alone.

The team first conducted experiments on cells growing in laboratory dishes and then on mice bearing human prostate tumors, according to the study, published in the online edition of the Proceedings of the National Academy of Sciences.

In the mice, the tumors shrank dramatically and all of the mice survived the study while the untreated control animals did not.

"A single injection of our nanoparticles completely eradicated the tumors in five of the seven treated animals, and the remaining animals also had a significant tumor reduction, compared to the controls," said Dr. Omid Farokhzad, assistant professor at Brigham and Women's Hospital and Harvard Medical School.

While all the parts of this new delivery system are known to be safe, it must still be proven safe for humans. The scientists said that further testing is needed on larger animals, and eventually in humans.

Some reports have suggested that nanoparticles might cause damage to cells and be hazardous to health because of their tiny size, and some experts advocate more research before they come into wide use.

According to the study, the researchers tailor-made tiny sponge-like nanoparticles laced with the drug docetaxel. The particles are designed to dissolve in a cells' internal fluids, releasing the anti-cancer drug either rapidly or slowly, depending on what is needed.

To make sure that only the correct cells are hit, the nanoparticles are "decorated" on the outside with targeting molecules called aptamers, or tiny chunks of genetic material.

Like homing devices, the aptamers specifically recognize the surface molecules on cancer cells, while avoiding normal cells.

The team chose nanoparticles as drug-delivery vehicles because they are so small that living cells will readily swallow them when at the cell's surface.

How to Digitally Record/Video a UFO sighting:

Como registar digitalmente ou gravar um vídeo de um avistamento de um UFO:

Stabilize the camera on a tripod. If there is no tripod, then set it on top of a stable, flat surface. If that is not possible lean against a wall to stabilize your body and prevent the camera from filming in a shaky, unsteady manner.

Estabilize a camera com um tripé. Se não tiver um tripé, então coloque-a em cima de uma superfície estável. Se não for possível, então encoste-se a uma parede para estabilizar o corpo e evitar que a camera registe de maneira tremida e instável.

Provide visual reference points for comparison. This includes the horizon, treetops, lampposts, houses, and geographical landmarks (i.e., Horsetooth Reservoir, Mt. Adams, etc.) Provide this in the video whenever is appropriate and doesn’t detract from what your focus is, the UFO.

Forneça pontos visuais de referência para comparação. Isso inclui o horizonte, cimo das árvores, postes de iluminação, pontos de referência geográficos (como o Reservatório de Horsetooth, Mone Adams, etc) Forneça esses pontos no vídeo sempre que for apropriado e não se distraia do que é o seu foco, o UFO/a Nave.

Narrate your videotape. Provide details of the date, time, location, and direction (N,S,E,W) you are looking in. Provide your observations on the weather, including approximate temperature, windspeed, any visible cloud cover or noticeable weather anomalies or events. Narrate on the shape, size, color, movements, approximate altitude of the UFO, etc and what it appears to be doing. Also include any unusual physical, psychological or emotional sensations you might have. Narrate any visual reference points on camera so they correlate with what the viewer will see, and thereby will be better able to understand.

Faça a narração do vídeo. Forneça pormenores sobre a data, hora, local e direcção (Norte, Sul, Este, Oeste) que está a observar. Faça observações sobre as condições atmosféricas, incluindo a temperatura aproximada, velocidade do vento, quantidade de nuvens, anomalias ou acontecimentos meteorológicos evidentes. Descreva a forma, o tamanho, a cor, os movimentos, a altitude aproximada onde se encontra o UFO/nave, etc e o que aparenta estar a fazer. Inclua também quaisquer aspectos pouco habituais de sensações físicas, psicológicas ou emocionais que possa ter. Faça a narração de todos os pontos de referência visual que o espectador irá ver e que, deste modo, será capaz de compreender melhor.

Be persistent and consistent. Return to the scene to videotape and record at this same location. If you have been successful once, the UFO sightings may be occurring in this region regularly, perhaps for specific reasons unknown, and you may be successful again. You may also wish to return to the same location at a different time of day (daylight hours) for better orientation and reference. Film just a minute or two under “normal” circumstances for comparison. Write down what you remember immediately after. As soon as you are done recording the experience/event, immediately write down your impressions, memories, thoughts, emotions, etc. so it is on the record in writing. If there were other witnesses, have them independently record their own impressions, thoughts, etc. Include in this exercise any drawings, sketches, or diagrams. Make sure you date and sign your documentation.

Seja persistente e não contraditório. Volte ao local da cena e registe o mesmo local. Se foi bem sucedido uma vez, pode ser que nessa região ocorram avistamentos de UFOs/naves com regularidade, talvez por razões específicas desconhecidas, e talvez possa ser novamente bem sucedido. Pode também desejar voltar ao mesmo lugar a horas diferentes do dia (durante as horas de luz)para ter uma orientação e referência melhor. Filme apenas um ,inuto ou dois em circunstâncias “normais” para ter um termo de comparação. Escreva tudo o que viu imediatamente após o acontecimento. Logo após ter feito o registo da experiência/acontecimento, escreva imediatamente as impressões, memórias, pensamentos, emoções, etc para que fiquem registadas por escrito. Se houver outras testemunhas, peça-lhes para registar independentemente as suas próprias impressões, pensamentos, etc. Inclua quaisquer desenhos, esbolos, diagramas. Certifique-se que data e assina o seu documento/testemunho.

Always be prepared. Have a digital camera or better yet a video camera with you, charged and ready to go, at all times. Make sure you know how to use your camera (and your cell phone video/photo camera) quickly and properly. These events can occur suddenly, unexpectedly, and often quite randomly, so you will need to be prepared.

Esteja sempre preparado, Tenha sempre uma camera digital, melhor ainda, uma camera vídeo consigo, carregada e pronta a usar sempre que necessário. Certifique-se que sabe como lidar com a sua camera (ou com o seu celular/camera fotográfica) rápida e adequadamente. Esses acontecimentos podem acontecer súbita e inesperadamente e, por vezes, acidentalmente, por isso, necessita estar preparado.

Look up. Be prepared. Report. Share.

Olhe para cima, Esteja preparado, Relate, Partilhe.
