The MRI-based technology can allow making new, green microchips and revolutionary sensors


In phys.org is an interesting article that the researchers create an MRI-like technique for imaging magnetic waves(1). The new ultrathin magnets can make many things in many fields of technology. The new sensor is using spin waves(2) for creating the magnetic field, and it can detect the magnetic field radiated inside the atom. That means this kind of technology can use in extremely small microchips and MRI(Magnetic Resonance Imaging)-based microscopes, which can detect the magnetic fields of objects, which is extremely small. 

The spin waves, which are created by using atom-thick magnets are promising information carriers because they are producing very low heat. And that means they can be used in the new nanotechnical microchips, which are controlling nanorobots. Using spin-waves the magnetic fields can move single atoms on the tables, and that thing opens new paths for nanotechnology. 

The system bases the nitrogen-vacancy (NV) centers where a nitrogen atom is sitting on the carbon diamond lattice. The rotating nitrogen atoms are creating the spin-field. That thing allows the system to detect very small-size objects by using magnetic fields. The problem with the MRI-technology is to create a small enough antenna or detector, which can separate the magnetic fields, what is coming from the resonating object. The idea of the MRI-scanner is that the hydrogen in the body is stressed with some kind of radiation. 

And then the hydrogen atoms will emit the radio frequential signal. In normal research of the human body, the accuracy of the MRI is about 1 mm. The problem with MRI-scanner is how to make the antenna, which can be small enough, that it would detect extremely small objects. And the benefit of MRI is that can observe the processes in the living cells. 

But the MRI can use to observe other things like bacteria and the thing, what interests researchers is how the bacteria is moving. The movement of the bacteria is a very well known thing. It happens by rotating the small fibers by using small electric motors. But the details of the process has been a mystery. And the thing can uncover how the bacteria is aiming its target. The MRI can uncover what kind of processes are causing that bacteria will start to aiming for some cells. The MRI can observe reactions in the living cells, which uncovers many things about their processes. 

If that process can uncover, the new type of chemicals can just call bacteria away from the area, where they can infect people. Or the movement of bacteria can just paralyze. Sama way the extremely accurate MRI-sensor can observe how virus releases its genome to the cell. If that thing can be denied, that will open the path to a new type of antiviral medicals. Those medicals can just deny the virus to release the genomes.

When robots are laughing and crying.

When robots are laughing and crying.  Does the AI have feelings?  Does the AI have feelings? Or can it be emphatic? The fact is this program code that controls the AI determines if it can give empathic reactions. The problem with the human nervous system is that we don't make a difference in the writing of empathic letters or telling empathic stories human or AI. Our nervous system is not adapted to AI yet. And that's why we cannot separate text written by AI from text that made by humans.  What does somebody make with AI that can emulate feelings? The fact is that the cyborgs are useful tools for infiltration operations. The human-size robots can have WLAN/6G connections with the central computers. Or they can form a neural network that shares information between all group members. The robots can also act as walking neural network-based supercomputers. That can make complicated solutions.  In those networks, each member shares information and their data-handling capacity all o

Earth 2.0 has been caused discussion about the possibility to find another civilization

    Earth 2.0 has been caused discussion about the possibility to find another civilization The Earth 2.0 or officially Kepler-452b is locating extreme log distance from Earth(1).    A new Earth-type planet has been found near the star, which is similar to our own Sun. The journey to that planet would take 1400 years, even if the spacecraft will reach the speed of the light. The planet has been found in the year 2008, but the confirmation of the existence of that planet has been taken time, but in 2015 the confirmation has been got, and Earth 2.0 has turned true.  The mass of that planet is 1,9 times Earth and the temperature is excellent if we are thinking about liquid water, but the journey to that planet will take so long, that we cannot ever go in there by using regular rockets and technology. The thing is that this kind of planets are the most interesting if we are looking for the lifeforms, which are similar to us, and the problem with that kind of things is that the communicatio

Tunguska meteorite and the natural nuclear fission

  Image I Tunguska meteorite and the natural nuclear fission 1) Tunguska UFO-theory  Tunguska meteorite is the mystery, that has been solved once, but then the case has been open again because Lake Cheko was not suitable for an impact crater. That lake has been introducing as an impact crater of the Tunguska meteorite. But the problem is that the shape of that lake is like a swimming pool. And that means it cannot form by a meteorite. So the mystery remains.  Meteorites can launch the natural nuclear fission if they hit the uranium ore, and transfer the impact energy to that ore. And is the thing that the famous "Tunguska" meteorite caused that kind of effect? There is also a theory that some "UFO" explode in that area, but the thing is that it is only theory, but interesting topics for some TV-series.  So I will begin this text by handling that theory, which is one of the incredible and outstanding theories in the world. Officially there is no physical evidence of
