Can kamikaze drones endanger the entire state?



Kamikaze drones or loitering ammunition are tools that are proven effective against Russia. But can those loitering ammunition endanger the Western military? If security personnel are not prepared. Those things can destroy soft targets like jet fighters. The kamikaze drones are excellent tools for surprise attacks. The attacker can bring them near targets in plastic bags. 

Or those drones can look like briefcases or canning jars. And if those drones can travel to a target without nobody disturbing them, they can cause bad damage at least stealth fighters and electric supply. If we think about things like cases where small-size drones are used to attack those drones can threaten a person's safety. They are almost perfect assassination tools. And that makes those systems very dangerous. 




Above: Implet, or contact mine, used in "Frankton" operation


When we think about things like ships and especially submarines the underwater quadcopters can cause new threats to marine systems. The quadcopter can carry similar contact mines to those used by British commandoes in the "Frankton" operation in Bordeaux harbor in, 1942. 

Those commandoes used contact mines and today things like stealth fighters or agents can deliver those destructive systems to the harbour. And then. They can search for targets like submarines and ships and connect to them using suction cups or other low-pressure systems. 

The system can work with a low-pressure chamber. When ventilation opens the system touches the hull of the ship. 

The pressure system's mission is to make ammunition contact and stay on antimagnetic hulls.  The system can use the cavity charge or regular explosive. The system can use image-ID and acoustic target recognition. It can prowl targets at the bottom of the harbors. 

Those devices can damage submarines or surface ships very badly. So if we think that drones can give a solution to the war, we must realize that there are many counteractions against them. But the problem is if those counter actions do not exist or they are not used drones are effective. Small-size drones can dropped to operational areas or near targets from aircraft. They can search things like bunker's entrances or missile silos. And. Those systems can also be used to eavesdrop and image intelligence.

The MIT sound-absorbing silk is a new and exciting innovation.


"MIT researchers developed a silk fabric, which is barely thicker than a human hair, that can suppress unwanted noise and reduce noise transmission in a large room. Credit: MIT News; iStock" (ScitechDaily, The Future of Silence Is Here: MIT’s Noise-Canceling Silk)

One of the newest practical innovations. Is sound-absorbing silk by MIT. Those kinds of materials are classified. The chemical compounds of them are not public. And they involve very interesting nanotechnology. The thing that makes this nanotechnology interesting is that the elastic and flexible structure can deny the noise. 

It is possible to make the 2D material structure like a non-linear graphene where the ball-shaped molecules jump between the walls of the nanotubes. That system's purpose is to pull energy out of the structure. The non-linear nanotubes conduct sound to the structure. The non-linear nanotubes mean that the graphene molecules are not in line. However, the MIT invention is elastic. And that means any structure can be covered by it. 

"MIT researchers have developed a silk fabric that suppresses sound using vibrations, offering two techniques: canceling noise through interference and preventing its transmission." (ScitechDaily, The Future of Silence Is Here: MIT’s Noise-Canceling Silk)

The nanotechnology behind the silk makes the structure the acoustic Faraday gage. In those models, the structure makes standing acoustic waves that travel into the fabric. It's possible. The structure in the fabric makes the acoustic fall that aims incoming waves at the strings. The side-coming waves pull energy out from incoming waves that attempt to travel through that silk. 

These kinds of innovations are tools that can revolutionize airports. The acoustic silk can deny or make the jet engine noise lower. The lightweight sound insulators can also in vehicles to make their noise lower. If that kind of acoustic silk is around the engines like turbines it can decrease the sound of the engine. That kind of silk can also used in face masks that allow the users to talk into the microphones and radios. But those systems deny outsiders to hear what those people say without technical devices. 

 Another thing is that this kind of effective, lightweight, transportable system can decrease the noise of the building sites. Make meetings more secure because people cannot hear things that meeting participants say. And that acoustic silk can protect places like band rooms so that neighbors don't hear the noise.

Ions and metasurfaces are the new tools for robotics.


"Schematics of multiplexing metadevices based on coherent wave interferences. Credit: OEA" (ScitechDaily, Pushing Optical Limits: Metasurfaces Achieve Near Infinite Light Control in a Single Device)


The new metasurfaces and ion channels turn information technology and nanomechanics forever. The photonic or photon-reacting and interacting metasurfaces make it possible to create devices that can operate independently in complex situations. 

Those photonic-controlled devices can make things like highly advanced morphing systems possible. In nanotechnology, it's essential to control systems. That is smaller than some molecules. And the metasurfaces are one thing that makes that system possible. When we think about systems like cars and robots that can change their shape, we must realize one thing. 

Those morphing surfaces will be created by nanomachines that act as the morphing neural network. Those small robots can take any form that they ordered. The system can interact with outsider observers like small drones that can tell that small, soundbite size nanorobot swarm how they should move to take a certain form. That thing means that the AI-controlled system can take any shape that it sees. The drone can make the 3D scanned image, and then order those nanorobots to take it. 

In some futuristic visions of the future, the data travels in the organic network. Those systems can be neurons or some hybrid cells. The long threads transport information like neurons. Those systems can transport information between those neurons by using the lion channels. Those ion channels make it possible for information to travel most of the time in chemical form. When that neurotransmitter reaches that neurotransmitter, it sends an electric impulse to the microchip that decodes the message. 

Ion channels are interesting. Those channels can form the ion superhighways that can make new ultra-secured data transmission possible. In those nanorobots, the system can have a small tube that transfers those ions from one place to another. The ion can transport information as well as electrons or photons.  There are multiple ways to make that data transportation. 



"Record ion speeds are achieved in organic conductors where local molecules can attract or repel ions from nanochannels that act as ion superhighways. Credit: Second Bay Studios" (ScitechDaily, Ion Superhighways: The Nanotech Breakthrough Powering Tomorrow’s Tech)

One is to use two ion channels and shoot ions through them. The ion channel one is the one in the binary system. And the ion channel two is the zero in the binary system. Those ion channels can be thousands of kilometers long. And that allows the system to transport ions over long distances. 

In some Sci-fi-Books that kind of system can also transport antimatter like positrons and anti-protons into the wanted point. This kind of system can installed in the robot bug. The robot bug transports those antimatter particles to the wanted point in the magnetic chamber, that puts them to flow. 

That denies antimatter contact with the walls of that chamber. Then the robot injects antiparticles through that ion accelerator or ion proboscis. That kind of weapon would be extremely horrible. And one of them can destroy even warships. The antimatter energy level is so high, that a gram of that matter turns the entire Earth into a molecular cloud. 

The ion-based information transport system is one of the versions of ultra-secured data transmission. The idea is that. The system can deny the outsider observer. To see ion. If the outsider harms the ion channel that thing is seen in control rooms. The receiving system must require the energy level and speed of ions to be at a certain level. Those things tell that ion is part of the message. 

The ion channel is also a vacuum, and if somebody wants to steal information, that launches the pressure sensor and denies the ion flow. The ion systems might not look as effective and wonderful as photonic systems. But they can interact between living neurons or organic microchips and regular, non-organic systems. In that system, the microchip transports information to the neuron cell's ion channel using the ions.

Solar wind research. And the use of diamonds to cool the atmosphere.

 

"In this animation, the CODEX instrument can be seen mounted on the exterior of the International Space Station. Credit: CODEX Team/NASA" (ScitechDaily, NASA’s CODEX Ready To Unlock Solar Wind Mysteries From the ISS)

NASA will send a CODEX instrument to the ISS to observe solar wind. 


"NASA’s Coronal Diagnostic Experiment (CODEX) is set to launch to the International Space Station to explore new details about the solar wind, including its origins and evolution."  (ScitechDaily, NASA’s CODEX Ready To Unlock Solar Wind Mysteries From the ISS)


The solar wind is well-known as an entirety. The solar wind is the particle flow that the source is in the sun. The mystery thing is how deep the solar wind forms. And the second question is how much the sun's magnetic field will accelerate those particles. And what role things like photons and impacting opposite and same polar particles play in that flow. 

So how much photons accelerate those ions and electrons? That information can help to build next-generation ion engines that have magnetic acceleration but things like laser beams can give extra punch to ions. 

Also, things like solar sails require information on the solar wind. That information can use to protect those system's electric components. And one thing is that the particles that form solar wind have very high energy levels. That makes it possible to use those things as energy sources. An interesting thing is how many of those particles can turn into antimatter when they fall into the atmosphere. The antimatter engines can create antimatter straight from the solar wind. 

Another interesting thing is the role of the solar wind in weather. The solar wind includes many interesting things. It drives small dust particles into Earth's atmosphere. And if it impacts satellites it can cause malfunction. This is one of the reasons why the solar wind is under research. 


"Globally averaged quantities resulting from 5 Mt/yr injections of the corresponding material (a) and (c) and quantities normalized by globally averaged net all sky top of the atmosphere (ToA) radiative forcing (RF) (b) and (d). Credit: Geophysical Research Letters (2024). DOI: 10.1029/2024GL110575" (Phys,org, Could injecting diamond dust into the atmosphere help cool the planet?)

The use of diamonds is one of the most expensive solutions for atmosphere cooling. Or is it? And other versions of that idea. 


Researchers think that injected diamond dust can decrease the temperature of the planet. The injected very cold nanodiamonds can act as the cooler beam, that can absorb heat from the air. Diamonds can form Bose-Einstein condensate that can absorb very much thermal energy. 

If researchers can send any material to space at the shadow side of Earth they can cool the atmosphere. Even if the air tank is sent to the orbiter and then somebody opens that tank can decrease the temperature on the ground. But there is a need for a large mass of that cooled gas. So that means that this is one of the most expensive ways to cool Earth's atmosphere. 

The use of diamond rain to cool the atmosphere is one of the most expensive ideas in the world. The idea is that the system will transport diamonds outside the atmosphere. Then it drops from the sky to the ground. And that means diamonds would bind thermal energy into themselves. That thing is very expensive. But what if somebody collects those diamonds or other particles back? 

The idea is that the system drops so-called nanodiamonds or "diamond sand" into the artificial lake. There can be the mylar tarpaulin on the bottom of the lake, and that thing can help to recycle those diamonds. The system must not use diamonds for that thing. The sand or water is the thing that can make this thing real as well as diamonds. 

The system can use so-called stratospheric satellites to transport particles to the high stratosphere. Then the system can wait until it releases its thermal energy to the high atmosphere. And then they can drop them to the ground. There are many versions of this thing. In some versions, the stratospheric satellite comes to the ground, pulls water into a tank, and then rises to the edge of the space. The system keeps water in motion, and then it will not turn into large ice bites. Then the system drops that artificial snow to the ground. 

There are suggested things like ultra-cold ions that the satellite shoots to the higher atmosphere to decrease the temperature on the ground. In some suggestions, people will create stratospheric towers that conduct air through the heat exchanger. Then that cooled air will drop to the ground.

Things like centrifugal launch systems that allow low-cost applications to shoot satellites to orbiters can make that kind of system possible. The system just shoots miniature satellites through the suborbital trajectory. Those satellites carry the particles like diamonds, snow, or sand that should cool on that trip. When they return to the atmosphere they release those particles to air.

Bacteriophages can take the form of sunflowers.



"McMaster University researchers found that bacteriophages treated under specific conditions form flower-like structures that are highly efficient in targeting bacteria, opening new possibilities for the treatment and detection of diseases." (ScitechDaily, Nature-Inspired Viruses Form Living “Sunflowers” To Combat Disease)

Complicated DNA-controlled structures can revolutionize medicine development. But it can make also many more things. 

Bacteriophages can make forms that look like sunflowers. Their ability to combine their bodies makes phages more effective against targeted bacteria. Sunflower-form virus structures can be a tool for researchers to use against infections. However, those virus structures are also interesting tools for people who create nanomachines and nanostructures. 

As you see, viruses can make complicated structures. And that makes it possible to use them to create structures for nanomechanics. The DNA-controlled crystal formation is the tool that developers can use to create the nanomachines. The nanomaterial means material that looks the same as normal material. But there are nanometer-sized internal structures. That gives those materials new abilities. If we think about things like nanotechnical wires. 



The ability to create complicated structures. Can make it possible to create medicines and structures that can make many things possible from medicine to nanomachines and DNA-based data storage. 

The nanotechnical wire can have structures that look like plates. There can be a pike on the other side of the plate. And hole at another side. That thing makes it possible to increase the length of the wire. Or if something cuts the wire. It's possible to create a structure that can fix itself. The only need is to put those gripping surfaces together. The nanowires can form structures like nano-canvas that can fix their damages without needing help. 

Nanotechnology is an impressive tool. The viruses that can take any form are the things that can make many things for nanotechnology. When the virus is made the structure the UV-radiation can destroy the DNA. And that helps to create a complicated crystal structure that is suitable for nanotechnology. 

The data can be stored in genetically engineered cells to create the wanted forms. (ScitechDaily, Nature-Inspired Viruses Form Living “Sunflowers” To Combat Disease)

The form of the cell can mean zero or one. The third form can mean. That the system must wait for the new cell. 

In DNA-based data storage, the system can use the forms that genetically engineered cells can take to transmit data to an AI-based operating system. 

If we think of the possibility of creating DNA-based data storage. There is one simple way to create that thing without the need to read the DNA. DNA-controlled viruses or cells can take a series of certain forms. There is a need for two or three forms if the DNA-based data storage uses binary data storage. 

Those forms like "star" can mean one, and "square" can mean zero. And ring might mean that the DNA ends and the system must wait for the next cell or virus group. There can be two groups of cells. The other is dark and another has a genome for bioluminance. The system shares the data in two cell lines and it can use the luminance to see that the system has changed the cell. 

The other forms have let's say pink and red colors. And the other is green and yellow. In those systems, the data is stored in two lines. The system feeds the reading system. By using those lines one after one. A change of color or shine tells that the cell or virus group is changed. And that makes the reader collect data together. 

Or red sunflower can mean one and yellow sunflower can mean zero. The green sunflower can mean the end of the DNA. The system requires a microscope with a machine view to observe those structures. The operating system follows those images. That the cells or viruses can make. And then it can use the DNA as data storage in an easy way.
