Revolution for nanotechnology: the engine that is 1/10,000th of a millimeter

 Revolution for nanotechnology: the engine that is 1/10,000th of a millimeter


In the future, the medicines might be packed in protein capsules. When that protein capsule faces the ion pump, that cell organ pushes medicine away from the nanomachine. One way to make that thing possible is to connect the protein or enzyme that makes the virus homing to certain cells to the nanomachine. The small-size nanomachine requires new technology. In some visions, the ion pumps that deliver nutrients to the cells can connect with nanomachines. And those nanomachines would use those ion pumps as ion engines. Controlling the nanomachine is very important.

Nanomachines can use enzymes that are long chemical fibers for dosing medicines. The medicine will connect to an enzyme that acts like a conveyor belt. And that enzyme travels over the nano-rolls that allow the nanomachine to apportion chemicals to cells. 



The enzyme can also connect with RNA, and it can transport that molecule into the desired position in the cells. The reason enzymes catalyze chemical reactions is that their shape is like wire. Other molecules, like acids, are connected with enzymes. The wire-looking molecule always transports new and fresh acid or some other molecules to the reaction point.

The nanomachine requires new, extremely small engine types. The size of those machines is smaller than a cell. And that is the reason why researchers investigate things like the swimming of sperm—that they can make the nanomachine move in liquid. In those processes, developers try to copy the movement mechanism in those cells into nanomachines.

The new nano-engine created by using RNA polymerase makes it possible to create engines for very small molecular machines that can transport drugs into the right cells. The new nanomachine is like a tweezer, where the structure pulls together and releases. 

And that thing can make the nanomachine able to touch things like molecules. So a nano engine is more useful than just an engine. Nanotechnology is the next-generation tool. And we don't yet know all the applications. What this thing like machines that are smaller than cells can have. But the nanomachines will revolutionize all technology in the world.

What is the difference between TR-3A and TR-3B? And are those planes real?

What is the difference between TR-3A and TR-3B? And are those planes real? Is TR-3B (0) "Black Triangle UFO" or is it only the piece of paper?  The study project, what is used to create advanced ideas for use of the nuclear-powered aircraft. Or is it the study project or black budget aircraft, where lost 2,3 trillion dollars (1)of the stealth bomber were gone. In this text is things, that might seem very difficult to accept, and when we are thinking about things like doubling the object or making it smaller by using huge layers of energy, nothing denies to test those things. But were those tests successful, there is no data about that in public Internet, so we must say that things like doubling the human or aircraft can be tested, but the results can be unknown.  But in the source two is the tale, what seems like impossible, those men, who got Noble Prize put at first time one atom to the box, and hit it with photon one photon in the box and hit it with th

Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.

  Mythic Planet X is an interesting thing because that allows the way to the perfect stealth technology.  Could a hypothetical Planet X tunnel all radiation?  The myth of Planet X still lives. Nobody ever saw that planet, and the thing that supports the theory of previously unknown large-size planets in Kuiper's belt are mysterious anomalies in Neptune's trajectory. The thing is that nothing else supports the theory of the existence of the "invisible planet". The size of the planet must be very big. And its gravitational field strong that it can affect Neptune's trajectory.  And the search for that mysterious planet is very long work. In some visions, the mysterious gravitational source is mentioned as the small black hole, but nobody understands why that black hole doesn't seem to interact.  In some other theories, Planet X is a glimpse of dark matter. And that thing makes it invisible. But there is one weakness. The dark matter object must have some kind of

Nanoparticles are excellent tools for medicine transporters.

"Researchers have developed a new therapy for pancreatic cancer involving nanoparticles that stimulate immune responses and improve drug delivery. This innovative method has led to significant tumor reduction in mice and holds potential for treating other cancers. Credit: SciTechDaily.com" (ScitechDaily, New Nanoparticle Cancer Treatment Successfully Shrinks and Eliminates Pancreatic Tumors) Nanoparticles can carry medicines into wanted cells. The idea is that the same system that feeds those cells transports those nanoparticles into cells that need medicine. When a nanoparticle goes, into a cell, it releases the chemicals into the targeted cells. Because nanoparticles don't let medical molecules interact with a body that makes it possible to create new and more powerful cytostatics. Nanoparticles can transport things like ricin molecules into wanted cells.  Ricin is one of the most poisonous chemicals. That chemical is useful for next-generation cytostatics, if researche
